Description

  The present invention relates to an information processing method and apparatus, a recording medium, and a program, and more particularly, to an information processing method and apparatus, a recording medium, and a program that make it easy to recognize a starting state when connecting transitions.

  Development tools that support the development of application software programs are becoming increasingly popular. For example, there is one that supports the development of an object-oriented program (for example, see Patent Document 1).

  Also, a UI (User Interface) development tool for an application software program using a state transition diagram represented by UML (Unified Modeling Language) has been proposed.

  The state transition diagram is a diagram in which an operation to be executed for each state is logically described, and a direction in which a transition is made to another state by a predetermined event occurring in each state is shown. The UI development tool of the application software program described above displays the program as a state transition diagram, and when the displayed state transition diagram itself is operated, the operation content of the state transition diagram is reflected in the program, Edit the program.

  By the way, in the development tool as described above, the state is expressed by a rectangular frame (state frame), and the state frame indicating the first state is shown to indicate that the state is shifted from the first state to the second state. And a state frame indicating the second state are connected by an arrow-like transition. The transition indicates that the state transitions from the state of the state frame that is the base point of the arrow to the state of the state frame that is the end point, and an event that is an operation that triggers the transition is displayed beside the transition.

  In the development tool described above, the transition is directly written in the state transition diagram using the pointer. More specifically, move the pointer over the state frame you want to start from and drag to start drawing an arrow, move to the state frame that will be the end point while dragging, and release the pointer. This completes the drawing of the arrow.

  However, in the state transition diagram, since the entire view is not necessarily displayed on the display screen, the state frame where the drawing of the transition is started and the end state frame may not be displayed on the same screen. In such a case, if an operation is performed such that the start position for drawing the transition protrudes from the screen, the state transition diagram scrolls correspondingly, and only the pointer moves on the state transition diagram by scrolling. Become.

  At this time, since the state of the state frame that is the starting point disappears from the screen by scrolling, if the state that becomes the starting point is forgotten during the operation, the state that becomes the starting point and ending point of the transition is mistakenly connected. There were times when I was lost. In addition, if you forget the starting state in the middle of the operation, in order to draw the transition more accurately, stop drawing the transition once and return to the position where the state frame of the starting state is displayed. It was necessary to scroll the transition diagram and check it again, which made the drawing of transitions cumbersome.

  The present invention has been made in view of such a situation, and in particular, when a transition is drawn, the drawing can be performed while accurately recognizing the starting state.

  In the process of generating the copy frame, a copy frame that is a copy of the starting state frame can be generated at a position near a predetermined position with respect to the start position of the editing transition.

Change the display color of and display. The transition 42 generates an arrow indicating a transition destination for each event that occurs during operation in each state.

  The editing transition generation unit 44 generates an editing transition drawn from the state frame that is the starting point based on the information about the transition being edited supplied from the editing unit 12.

  The accompanying state frame generation unit 43 generates a copy of the state frame in a state that is the starting point of the transition at a predetermined position near the start position of the editing transition. At this time, the generated copy is generated based on the accompanying state frame setting data set by the accompanying state frame setting data setting unit 45 in advance.

  The state transition engine 15 reads out the state data stored in the state data storage unit 13 and searches the current state based on the event information supplied from the event detection unit 19 and obtains the current search result. Information indicating the current state is supplied to the state transition diagram generation unit 14 and the state operation execution unit 16.

  The state operation execution unit 16 executes the operation of the current state based on the state data of the current state supplied from the state transition engine 15 and supplies the execution result to the display control unit 17.

  The display control unit 17 includes a state transition diagram display control unit 51 and a state operation display control unit 52, and generates and displays a display screen to be displayed on the display unit 18.

  The state transition diagram display control unit 51 generates, for example, the state transition diagram display screen 111 of FIG. 2 based on the information of the state transition diagram supplied from the state transition diagram generation unit 14, and controls the display. In FIG. 2, a state frame 131 indicating a state A (State A), a state frame 132 indicating a state B (State B), a state frame 133 indicating a state C (State C), In addition, a state frame 134 indicating a state D (State D) is shown, and each is connected by transitions 141 to 148. Transitions 141 to 148 indicate the direction and event of transition between states.

  More specifically, the transition 141 is indicated as “KeyPress_x”, the arrow is displayed from the state A to the state D, and when the operation of the state A is executed, the “x” of the operation unit 11 is displayed. When an event that a key is operated occurs, the state A changes to the state B.

  Similarly, the transition 142 is indicated as “KeyPress_2”, the arrow is displayed from the state A to the state B, and when the operation of the state A is executed, the key “2” of the operation unit 11 is displayed. When an event to be operated occurs, the state A transitions to the state B.

  In addition, the transition 143 is indicated as “KeyPress_3”, the arrow is displayed from the state B to the state A, and when the operation of the state B is executed, the “3” key of the operation unit 11 is operated. When an event occurs, the state B transitions to the state A.

  Further, the transition 148 is indicated as “KeyPress_z”, the arrow is displayed from the state D to the state A, and when the operation of the state D is executed, the “z” key of the operation unit 11 is operated. When an event occurs, the state D changes to the state A.

  Returning to the description of FIG.

  The state operation display control unit 52 generates a state operation screen 112 as shown in FIG. 2 based on the execution result of the state operation supplied from the state operation execution unit 16, and controls the display.

  The display unit 18 includes a CRT (Cathode Ray Tube) or an LCD (Liquid Crystal Display), and displays a screen generated by the display control unit 17.

  Next, state information stored in the state data storage unit 13 will be described with reference to FIG.

  For example, when the state transition diagram as shown in the state transition diagram display screen 111 of FIG. 2 is configured, the state information is stored in the state data for each of the states A to D in the state as shown in FIG. Stored in the unit 13. In FIG. 3, the data structure of state information is shown in the order of states A to D from the left.

  In each state (state), an area in which information of a state that is a transition destination corresponding to each event is recorded as transition information. In addition, an area for recording a script in each state is secured.

  That is, in the state A (State A) of FIG. 3, “KeyPress_2” and “KeyPress_x” are recorded in the event column as transition information, and “State B” and “State D” are respectively set as the corresponding transition destinations. It is recorded. That is, the transition information is recorded as information corresponding to the transitions 142 and 141 in FIG. In the case of state A, “script A” (a description indicating an operation executed in state A) is recorded as script information under the transition information.

  Furthermore, in state B (State B), “KeyPress_3” and “KeyPress_b” are recorded in the event column as transition information, and “State A” and “State C” are recorded as the corresponding transition destinations, respectively. Yes. That is, this transition information is recorded as information corresponding to the transitions 143 and 144 in FIG. In the state B, “script B” is recorded as script information under the transition information.

  Furthermore, in state C (State C), “KeyPress_a” and “KeyPress_1” are recorded in the event column as transition information, and “State B” and “State D” are recorded as the corresponding transition destinations, respectively. Yes. That is, this transition information is recorded as information corresponding to the transitions 145 and 146 of FIG. In the state C, “script C” is recorded as script information under the transition information.

  Furthermore, in state D (State D), “KeyPress_z” and “KeyPress_0” are recorded in the event column as transition information, and “State A” and “State C” are recorded as the corresponding transition destinations, respectively. Yes. That is, this transition information is recorded as information corresponding to the transitions 148 and 147 in FIG. In the state D, “script D” is recorded as script information under the transition information.

  Next, the state transition program editing process by the editing unit 12 will be described with reference to the flowchart of FIG.

  In step S <b> 1, the state editing unit 31 determines whether or not state editing is instructed based on the signal supplied from the operation unit 11. In step S1, for example, when it is determined that state editing processing has been instructed, in step S2, the state editing unit 31 executes state editing processing, and the processing returns to the original. The state editing process will be described later with reference to FIG.

  In step S1, for example, when it is determined that the state editing process is not instructed, in step S3, the transition editing unit 32 determines whether transition editing is instructed based on the signal supplied from the operation unit 11. Determine whether. In step S3, for example, when it is determined that the transition editing process has been instructed, in step S4, the transition editing unit 32 executes the transition editing process, and the process returns to the original. The transition editing process will be described later with reference to FIG.

  In step S3, for example, when it is determined that the transition editing process is not instructed, in step S5, the script editing unit 33 determines whether script editing has been instructed based on the signal supplied from the operation unit 11. Determine whether. In step S5, for example, when it is determined that the script editing process is instructed, in step S6, the script editing unit 33 executes the script editing process, and the process returns to the original. The script editing process will be described later with reference to FIG.

  Since the state data is updated by the above processing, the corresponding state transition program is updated.

  Next, the state editing process will be described with reference to the flowchart of FIG.

  In step S <b> 21, the state editing unit 31 determines whether the process is a process of generating a new state (state) based on the signal from the operation unit 11. For example, when a button (not shown) on the display screen 101 in FIG. 2 is operated and a process for generating a new state is instructed, in step S22, the state editing unit 31 generates a new state. That is, the state editing unit 31 records state information corresponding to the new state in the state data storage unit 13.

  In step S23, the state editing unit 31 sets the newly generated state as the editing target state.

  In step S24, the state editing unit 31 determines whether there is an update in the state information of the editing target state. Here, whether or not there is an update is determined in the state information such as the state name and the display position of the corresponding state frame. That is, the state editing unit 31 edits the state name and the state frame display position information among the state information.

  In step S24, when it is determined that the state name and the display position information of the state frame are updated in the state information, in step S25, the state editing unit 31 displays the updated state name and state frame. The position information is updated by reflecting it in the state information of the edit target state.

  On the other hand, if it is determined in step S24 that there is no update, the process of step S25 is skipped.

  In step S26, it is determined whether or not the end of the state editing process is instructed. If the end is not instructed, the process returns to step S24, and if it is determined that the end is instructed, the state editing process ends. .

  If it is determined in step S21 that a new state is not generated, it is determined in step S27 whether an existing state is selected. That is, any of the existing state frames 131 to 134 displayed on the state transition diagram display screen 111 as shown in FIG. 2, for example, which is displayed by a display process described later with reference to FIG. Whether or not any of the state information stored in the state data storage unit 13 of the corresponding state A to D is selected is determined based on whether or not the pointer is selected by operating the operation unit 11. For example, when state information of an existing state is selected, in step S28, the state editing unit 31 sets the selected state as an editing target state, and the process proceeds to step S24.

  On the other hand, if it is not determined in step S27 that an existing state has been selected, the process returns to step S21, and the subsequent processes are repeated.

  That is, by the above processing, the state name and the display position of the state frame are newly set or updated for state information of a new state or an existing state.

  Next, the transition editing process will be described with reference to the flowchart of FIG.

  In step S41, the transition editing unit 32 determines whether or not the operation button of the operation unit 11 has been pressed. More specifically, when the operation unit 11 is a mouse, for example, the operation unit 11 determines whether or not a mouse operation button has been pressed. For example, when it is determined in step S41 that the operation button of the operation unit 11 has been pressed, the process proceeds to step S142.

  In step S42, the transition editing unit 32 sets the drag mode to OFF, and initializes information on the edit target state (state to be edited). That is, at present, the drag mode is not performed and the edit target state is not set. The drag mode refers to a mode in which any of the editing objects is fixed to a pointer (mouse pointer) when the operation button of the operation unit 11 is pressed, and can be moved in synchronization with the pointer. If there is no, no editing target is set to move in synchronization with the pointer.

  In step S43, the transition editing unit 32 acquires the position (Xc, Yc) of the pointer based on the signal from the operation unit 11.

  In step S44, the transition editing unit 32 accesses the state data storage unit 13 and determines whether or not the position (Xc, Yc) of the pointer is in any state frame. For example, as shown in FIG. 7, when the pointer 171 exists in the state frame of the state A of the state frame 131, the pointer position (Xc, Yc) exists in the state frame 131. The position (Xc, Yc) is set to the start position (Xs, Ys) of the editing transition, and the process proceeds to step S45.

  In step S45, the transition editing unit 32 sets the state A of the state frame 131 to the editing target state, and the process proceeds to step S46.

  In step S46, the transition editing unit 32 determines whether or not the operation unit 11 has been operated to instruct the end of the transition editing. When the end is instructed, the process ends. On the other hand, if it is determined in step S46 that the end of editing has not been instructed, the process returns to step S41.

  Furthermore, if the pointer position (Xc, Yc) is not in any state frame in step S44, the process in step S45 is skipped, and none of the states is maintained as an editing target state. It becomes.

  When it is determined in step S41 that the operation button of the operation unit 11 is not just pressed, the transition editing unit 32 is pressed and moved in step S47. It is determined whether or not. If it is determined in step S47 that the operation button of the operation unit 11 has been pressed and moved, it is determined in step S48 whether or not an edit target state exists.

  For example, when the operation unit 11 is operated from the state shown in FIG. 7 and the pointer 171 is pressed and moved in any direction, the edit target state is set to the state A indicated by the state frame 131. Therefore, it is determined that there is an editing target state, and the process proceeds to step S49.

  In step S49, the transition editing unit 32 acquires the position (Xc, Yc) of the pointer.

  In step S50, the transition editing unit 32 determines whether or not the drag mode is set. In this case, since the drag mode is not set, the process proceeds to step S51.

  In step S51, the transition editing unit 32 controls the state transition diagram generating unit 14 to delete the editing transition drawn so far and the accompanying state frame described later. At this time, the accompanying state frame generation unit 43 and the editing transition generation unit 44 of the state transition diagram generation unit 14 generate the editing transition (displayed by the display processing described later) generated for editing in the processing so far. , All the accompanying state frames are deleted.

  In step S52, the transition editing unit 32 controls the state transition diagram generating unit 14 to draw an editing transition from the edit target state to the pointer position (Xc, Yc). At this time, for example, the edit transition generation unit 44 of the state transition diagram generation unit 14 generates an edit transition 181 from the state frame 131 of the state A that is the edit target state to the pointer 171 as shown in FIG. Then, it is supplied to the display control unit 17 (the generated editing transition is displayed by display processing by the display control unit 17 described later).

  In step S53, the transition editing unit 32 supplies the information of the pointer position (Xc, Yc) and the start position (Xs, Ys) to the state transition diagram generation unit 14 to execute the accompanying state frame generation process, for example, An adjoint state frame 182 as shown in FIG. 8 is generated.

  Here, the accompanying state frame generation processing will be described with reference to the flowchart of FIG.

  In step S81, the accompanying state frame generation unit 43 reads the accompanying state frame setting data set by the accompanying state frame setting data setting process described later with reference to FIG. The accompanying state frame setting data includes information on transparency when displaying the accompanying state frame, distance L, reduction ratio with respect to the editing target state frame, and foreground color. Details of the accompanying state frame setting data will be described later.

In step S82, the accompanying state frame generation unit 43 determines the pointer position (Xc, Yc) and the start position (Xc, Yc) based on the pointer position (Xc, Yc) and the start position (Xs, Ys) from the transition editing unit 32. Xs, Ys) is determined whether or not the distance (= √ ((Xc−Xs) ² + (Yc−Ys) ² )) is longer than the distance L that can be displayed in the associated state frame. To do. Here, the distance L is a distance from the start position of the editing transition 181 to the center position for displaying the accompanying state frame 182 as shown in FIG. This is the distance that the accompanying state frame 182 cannot be displayed unless 181 exists. The distance L is preferably a distance in the vicinity from the pointer position (Xc, Yc).

  Therefore, if the length of the edit transition 182 is equal to or longer than the distance L in step S82, the accompanying transition 182 can be drawn, and the process proceeds to step S83.

  In step S <b> 83, the accompanying state frame generation unit 43 obtains the center position of the accompanying state frame 182. Here, as shown in FIG. 10, the center position (Xd, Yd) is a position on the editing transition 181 and a distance L from the position (Xc, Yc) of the pointer 171. Note that the center position of the accompanying state frame is not limited to the position shown in FIG. 10 but may be set in the vicinity of the pointer 171. For example, the editing transition frame 181 is not covered with the editing transition 181. It may be set in the vicinity of the position (Xc, Yc) of the pointer 171 on the extension of 181.

  In step S84, the accompanying state frame generation unit 43 generates the state frame to be edited by reducing the size so that the obtained center position (Xd, Yd) is centered based on the accompanying state frame setting data. The generated transparency and foreground color are generated and supplied to the display control unit 17 (the generated accompanying state frame is displayed by display processing by the display control unit 17 described later).

  With the above processing, the accompanying state frame 182 in which the editing target state frame 134 is reduced as shown in FIG. 8 is generated following the position of the pointer 171.

  Now, the description returns to the flowchart of FIG.

  In step S54, the transition editing unit 32 turns on the drag mode. As a result, after that, if the pointer 171 is moved while the operation button of the operation unit 11 is kept pressed, it is determined in step S50 that the drag mode is set. Is skipped, and the processing of steps S41, S47 to S50, S52 to S54, and S46 is repeated, so that the edit target state frame 134 is reduced following the movement of the pointer 171 shown in FIG. The associated state frame 182 thus displayed continues to be displayed.

  Further, when it is determined in step S47 that the mouse is pressed and not moved, the transition editing unit 32 determines whether or not the operation button of the operation unit 11 is released in step S55. For example, if the operation button of the operation unit 11 is released when the pointer moves to the state frame of the transition destination, it is determined that the operation button has been released. Therefore, the process proceeds to step S56, and the transition editing is performed. The unit 32 determines whether or not the edit target state exists. In this case, since the editing target state is state A, it is determined that there is an editing target state, and the process proceeds to step S57.

  In step S57, the transition editing unit 32 determines whether or not the drag mode is set. In this case, since the drag mode remains on in step S54, it is determined in step S57 that the drag mode is set, and the process proceeds to step S58.

  In step S58, the transition editing unit 32 acquires the position (Xc, Yc) of the pointer based on the signal from the operation unit 11.

  In step S59, the transition editing unit 32 accesses the state data storage unit 13, and determines whether or not the position of the pointer (Xc, Yc) is a position in any state frame excluding the editing target state frame. judge. For example, as shown in FIG. 11, when the pointer 171 exists in the state frame of the state frame 133 in the state C, the position (Xc, Yc) of the pointer 171 exists in the state frame 133. The process proceeds to step S60.

  In step S60, the transition editing unit 32 sets the state of the state frame at the position where the pointer 171 is present as the transition destination state (state). At this time, the transition editing unit 32 controls the editing transition generating unit 44 of the state transition diagram generating unit 15 to delete the editing transition, and controls the transition generating unit 42 to control the transition 201 indicating the original transition destination. To draw.

  In step S61, the transition editing unit 32 requests to specify an event. More specifically, that is, for example, when the transition 201 in FIG. 11 is pulled by the pointer 171 as a process of specifying the transition destination, the transition editing unit 32 specifies an event beside the transition 201 (not shown). Displays a blank and prompts for input.

  In step S62, the transition editing unit 32 determines whether an event for transition is specified, and repeats the process until it is determined that the event has been specified. That is, the transition editing unit 32 determines whether or not information specifying an event is input to the blank, and determines whether or not an event is specified.

  In step S62, for example, as shown in FIG. 11, when an event that the key “Q” of the operation unit 11 is input is designated as indicated by “KeyPress_Q”, it is determined that the event is designated. Then, the process proceeds to step S63.

  In step S63, the transition editing unit 32 accesses the state data storage unit 13, reads the state information of the editing target state, and updates it by reflecting the specified transition destination and event information. That is, for example, in the case of the transition 141 in FIG. 2, “State C” is newly designated as the transition destination and “KeyPress_Q” is designated as the event, so that the transition destination is shown in the left part of FIG. "State C" and "KeyPress_Q" are added to the event and updated.

  On the other hand, if there is no edit target state in steps S48 and S56, the process proceeds to step S46. If it is determined in step S59 that there is no state frame at the position (Xc, Yc), the transition editing unit 32 and the accompanying state frame generation unit 43 of the state transition diagram generation unit 14 and the editing transition are determined in step S64. The generation unit 44 is controlled to delete the editing transition and the accompanying state frame that have been drawn so far.

  With the above processing, it is possible to edit transition information simply by operating the pointer with the operation unit 11 and drawing an arrow from the state frame of the editing target state to the state frame of the transition destination. In addition, when a transition is edited, the editing transition is displayed until the transition destination is confirmed, and the editing is performed in the vicinity of the pointer by following the movement of the pointer existing at the head position of the editing transition. Since the state frame of the target state is displayed as an accompanying state frame in a reduced state, when the transition is drawn, the state transition diagram is scrolled on the state transition diagram display screen 111, etc. Even if there is no state frame for the state, information on the edit target state that is the starting point is displayed in the accompanying state frame, so it is possible to recognize the edit target state (the state that is the starting point of the transition) Thus, the transition can be easily created.

  Next, script editing processing will be described with reference to the flowchart of FIG.

  In step S101, the script editing unit 33 determines whether an existing state is selected, and repeats the process until it is selected. That is, any of the existing state frames 131 to 134 displayed on the state transition diagram display screen 111 as shown in FIG. 2, for example, displayed by the display process described later with reference to FIG. Whether or not any of the state information stored in the state data storage unit 13 of the corresponding state A to D is selected is determined based on whether or not a pointer (not shown) is selected by operating the operation unit 11. . In step S101, for example, when state information of an existing state is selected, in step S102, the script editing unit 33 sets the selected state as an editing target state, and the process proceeds to step S103. .

  In step S103, the script editing unit 33 determines whether the script has been updated. More specifically, the script editing unit 33 determines whether or not the description content of the script information has been updated by the operation unit 11.

  In step S103, for example, if it is determined that the script information has been updated, in step S104, the script editing unit 33 accesses the state data 13, reads the state information of the editing target state, changes the script, Update information.

  In step S105, the script editing unit 33 determines whether or not the end of the script editing process is instructed. If the end is not instructed, the process returns to step S101. If the end of the state editing process is instructed, the process ends.

  The script is edited by the above processing.

  Next, the state transition program execution process will be described with reference to the flowchart of FIG.

  In step S111, the state transition engine 15 determines whether any state on the state transition diagram display screen 111 is selected based on the operation signal transmitted from the operation unit 11, and until the state is selected. Repeat the process. More specifically, the state transition engine 15 does not show any of the state frames 131 to 134 on the state transition diagram display screen 111 of FIG. 2 based on the signal supplied from the operation unit 11, for example. It is determined whether or not the pointer is selected, and the process is repeated until any state is selected.

  In step S111, for example, when any state is selected, in step S112, the state transition engine 15 sets the selected state as the current state. That is, based on the signal from the operation unit 11, for example, the state transition engine 15 sets a state frame selected by a pointer (not shown) among the state frames 131 to 134 on the state transition diagram display screen 111 in FIG. Set the corresponding state to the current state.

  In step S <b> 113, the state transition engine 15 accesses the state data storage unit 13, reads state information of the current state, and supplies the state information to the state operation execution unit 16.

  In step S114, the state operation executing unit 16 interprets the supplied state information of the current state. That is, the state operation execution unit 16 reads script information, in particular, of the supplied current state state information, and recognizes the operation in that state.

  In step S115, the state operation execution unit 16 executes the process described in the script information.

  In step S116, the state operation executing unit 16 determines whether or not the end of the state transition process is instructed. That is, the state operation executing unit 16 determines whether or not the end of the state transition process has been instructed based on the signal from the operation unit 11, and if the end has not been instructed, the process proceeds to step S117. .

  In step S117, the state transition engine 15 determines whether an event has occurred. That is, the state transition engine 15 determines whether or not the information of the event detected by the event detection unit 19 has been supplied. If there is no event, the process returns to step S115 and the subsequent processes are repeated. . That is, the processes in steps S115 to S117 are repeated until an event is detected. On the other hand, if it is determined in step S117 that there is an event, the process proceeds to step S118.

  In step S118, the state transition engine 15 determines whether or not the transition destination is set based on the supplied event information. That is, when the state information is shown in FIG. 3 and the current state is state A, for example, as an event, an event that the “A” key of the keyboard of the operation unit 11 is operated. Even if this occurs, the transition destination is not set. For this reason, in such a case, the process returns to step S115. That is, it is processed as if the event did not substantially occur.

  On the other hand, if it is determined in step S118 that there is a transition destination, that is, if the state information is as shown in FIG. 3 and the current state is state A, for example, as an event, the operation unit When an event occurs in which the “2” key of 11 keyboards is operated, the transition destination B is set. Therefore, in step S102, the state transition engine 15 sets the transition destination state as the current state, the process returns to step S113, and the subsequent processes are repeated. That is, by this process, the state B as a new transition destination is set as the current state, and the processes after step S113 are repeated.

  With the above processing, the state transition engine 15 changes the state according to the state transition diagram based on the event information supplied from the event detection unit 19, reads out the state information of the corresponding state, and sends it to the state operation execution unit 16. It becomes possible to supply. Further, the state operation executing unit 16 changes the state set based on the user's operation, and the state operation executing unit 16 can execute the operation specified by the script in the corresponding state. ,

  Next, state transition diagram generation processing will be described with reference to the flowchart of FIG.

  In step S131, the state transition diagram generation unit 14 accesses the state data storage unit 13 and reads all stored state data.

  In step S132, the state frame generation unit 41 generates a state frame on the state transition diagram for every state information, and describes the description contents of all scripts in the state frame based on the script information.

  In step S133, the transition generation unit 42 generates a transition based on the transition destination information corresponding to the event in the state information.

  In step S134, the state transition diagram generation unit 14 generates information constituting the state transition diagram based on the state frame generated by the state frame generation unit 41 and the transition generated by the transition generation unit 42, and performs display control. The process is supplied to the unit 17, and the process returns to step S131, and the subsequent processes are repeated.

  Through the above processing, a state transition diagram can be generated based on the state information stored in the state data storage unit 13 and supplied to the display control unit 17.

  Next, display processing will be described with reference to the flowchart of FIG.

  In step S <b> 141, the state transition diagram display control unit 51 displays the state transition diagram display screen 111 based on the state transition diagram information supplied from the editing transition generation unit 44 of the state transition diagram generation unit 14.

  In step S142, the state transition diagram display control unit 51 determines whether an editing transition is supplied from the editing transition generation unit 44 of the state transition diagram generation unit 14. For example, when the image information on the state transition diagram of the editing transition is supplied by the process of step S52 in the transition editing process of FIG. 6, it is determined that the editing transition is supplied. It is displayed on the transition diagram display screen 111.

  On the other hand, if it is determined in step S142 that the editing transition has not been supplied, the process of step S143 is skipped.

  Further, in step S144, the state transition diagram display control unit 51 determines whether or not the accompanying state frame has been supplied from the accompanying state frame generating unit 43 of the state transition diagram generating unit 14. For example, when the image information on the state transition diagram of the accompanying state frame is supplied by the process of step S53 in the transition editing process of FIG. 6, it is determined that the accompanying state frame is supplied. It is displayed on the transition diagram display screen 111.

  On the other hand, if it is determined in step S144 that the accompanying state frame has not been supplied, the process of step S145 is skipped.

  In step S146, the state operation display control unit 52 determines whether or not the current state is designated based on the information supplied from the state transition diagram generation unit 14. In step S146, for example, when it is determined that the current state is designated, in step S147, the state operation display control unit 52 performs the operation executed by the state operation executing unit 16 set as the current state. The state operation screen 112 is displayed based on the content, and the processing returns to step S141.

  If the current state is not designated in step S146, the process in step S147 is skipped.

  Through the above processing, the display screen 101 including the state transition diagram display screen 111 and the state operation screen 112 as shown in FIG. 2 is displayed on the display unit 18.

  The state transition program editing process of FIG. 4, the state editing process of FIG. 5, the transition editing process of FIG. 6, the script editing process of FIG. 13, the state transition program execution process of FIG. 14, the state transition diagram generation process of FIG. The following operations are realized by the display processing of FIG.

  The transition state information (state data) is edited by the state editing process of FIG. 5 in the state transition program editing process of FIG. 4, the transition editing process of FIG. 6, and the script editing process of FIG. 13, and the state transition program execution process of FIG. The state transition process is executed based on the state transition information edited by. Further, a state transition diagram is generated based on the state transition information edited by the state transition program execution process of FIG. At this time, when the transition editing process of FIG. 6 is executed, the editing transition and the accompanying state frame are supplied to the display control unit 17 as information of the state transition diagram. As a result, in the display process of FIG. 16, a state transition diagram based on the edited state transition information is displayed, and when the transition editing process is being executed, the editing transition and the accompanying state are further displayed. A frame will be displayed.

  As a result, when the transition is edited, the state frame of the state to be edited is reduced in the vicinity of the movement of the pointer at the beginning of the transition until the transition destination of the transition is determined. Since it will be displayed in the accompanying state frame of the state, when drawing a transition, even if there is no state frame of the editing target state on the state transition diagram display screen 111, the editing target state Can be recognized, and transitions can be easily created.

  Next, the accompanying state frame setting data setting process will be described with reference to the flowchart of FIG.

  In step S161, the accompanying state frame setting data setting unit 45 determines whether or not setting of the accompanying state frame setting data is instructed, and repeats the process until setting of the accompanying state frame setting data is instructed. For example, when the operation unit 11 is operated and setting of the accompanying state frame setting data is instructed, the accompanying state frame setting data setting unit 45 displays the setting screen on the display unit 18 via the display control unit 17 in step S162. Display.

  At this time, the accompanying state frame setting data setting unit 45 displays a setting screen 251 as shown in FIG. 18, for example. In FIG. 18, “copy display attribute” is displayed at the top of the setting screen 251, the accompanying state frame is a copy of the editing target state frame, and the display attribute is the setting data of the accompanying state frame. It is shown that.

  In FIG. 18, “transparency”, “L”, “reduction ratio”, and “foreground color” are displayed from the top of the setting screen 251, and the transparency and distance L (FIG. 10) when the accompanying state frame is displayed. ), Setting items for the reduction ratio for the editing target state frame and the foreground color of the accompanying state frame. The transparency is displayed in% and is set in the range of 0 to 100. As the value of transparency is higher, the transparency is higher. For example, when the value is 0%, the transparency is not completely transparent. As described with reference to FIG. 10, the distance L indicates the distance from the position of the pointer to the center position of the accompanying state frame displayed in units of pixels. The reduction ratio is a reduction ratio with respect to the edit target state frame, is displayed in%, and is set in a range of 0 to 100. The foreground color is an item for designating the foreground color of the accompanying state frame, and is set in the range of 0 to 255 for the three primary colors of RGB light from the left. In the case of FIG. 18, R (Red) is set to 0, G (Green) is set to 255, B (Blue) is set to 0, and the foreground color is displayed in green.

  In step S163, the accompanying state frame setting data setting unit 45 determines whether or not the accompanying state frame setting data has been set, and repeats the process until it is determined that the setting has been made. For example, if it is determined that all settings have been made, in step S164, the accompanying state frame setting data setting unit 45 updates and stores the accompanying state frame setting data as shown in FIG.

  With the above processing, the accompanying state frame setting data for displaying the accompanying state frame is set, so that the accompanying state frame can be displayed with desired transparency, position, size, and color.

  According to the above, when the transition is edited, until the transition destination of the transition is determined, the movement of the pointer existing at the start position of the transition is followed and the edit target state (the transition start point and State state) is displayed as an associated state frame in a reduced state. Therefore, when a transition is drawn, even if there is no state frame of the edit target state on the state transition diagram display screen 111, the accompanying state frame is displayed. It is possible to recognize the state to be edited simply by looking at the state frame, and when drawing a transition, it is possible to draw while accurately recognizing the starting state.

An editing step of editing state transition information including information on an operation in each state, an event at the time of transition in each of the states, and a transition direction indicating which other state is to be transitioned by the event;
A display step for displaying a state transition diagram based on the state transition information edited by the processing of the editing step;
An operation step of operating the state transition diagram displayed by the processing of the display step;
In accordance with the operation content in the processing of the operation step, an edit transition generation step for generating an edit transition from a state frame indicating a state serving as a starting point on the state transition diagram;
A copy frame generation step for generating a copy frame that is a copy of the starting state frame at a position near the start position of the editing transition;
If the start position of the editing transition is connected to a state frame different from the starting state according to the operation content in the operating step processing, the editing step processing is the starting point. A recording medium on which a computer-readable program is recorded for editing the state transition information so that a state different from the state is a transition destination in the starting state. An editing step of editing state transition information including information on an operation in each state, an event at the time of transition in each of the states, and a transition direction indicating which other state is to be transitioned by the event;
A display step for displaying a state transition diagram based on the state transition information edited by the processing of the editing step;
An operation step of operating the state transition diagram displayed by the processing of the display step;
In accordance with the operation content in the processing of the operation step, an edit transition generation step for generating an edit transition from a state frame indicating a state serving as a starting point on the state transition diagram;
A copy frame generation step for generating a copy frame that is a copy of the starting state frame at a position near the start position of the editing transition;
If the start position of the editing transition is connected to a state frame different from the starting state according to the operation content in the operating step processing, the editing step processing is the starting point. A program that causes a computer to execute a process of editing the state transition information so that a state different from a state becomes a transition destination in the starting state.
