Each function is not limited to executing the process described in the following embodiment. Which process is realized by which function can be appropriately selected.

Player character control unit 31A
The player character control unit 31A controls the action of the player character 50 in the virtual game space. Specifically, the player character control unit 31 </ b> A is based on the operation of the controller 38 by the user from a state where the player character 50 is confined in a room in the virtual game space by the non-player character 51 that is hostile to the player character 50. The operation to escape from the room door 43 (see FIG. 6) is controlled.

  In the escape game, the player character 50 aims to escape from the room while solving the mysteries provided in the confined room in order based on the operation of the controller 38 by the user.

  A plurality of objects (operation target objects) for solving a mystery are provided in the room. Although details will be described later, the above-described operation target object can be returned to the original state (that is, the state before the operation) even if the player character 50 is operated, and once the player character 50 is operated. There are things that can never be restored (irreversible objects).

Non-player character control unit 31B
The non-player character control unit 31B takes the non-player character 51 out of the room and returns the non-player character 51 to the room in response to a predetermined action by the player character 50 after the non-player character 51 leaves the room. Control behavior. For example, it is assumed that the player character 50 makes a noise due to a failure action such as breaking a glass in a confined room. Based on this point in time, for example, after one minute, the non-player character control unit 31B controls the non-player character 51 to return to the room.

  Here, when the non-player character 51 returns to the room, the object determination unit 31D described later determines whether all of the plurality of operation target objects provided in the room are in the original state. If even one operation target object is not in the original state, the non-player character control unit 31B causes the non-player character 51 to punish the player character 50 such as, for example, a whip. The movement of the character 51 is controlled. Details will be described later.

Object creation / restoration unit 31C
The object generation / restoration unit 31C generates one or a plurality of operation target objects that the player character 50 operates (touches) to escape from the room. For example, as illustrated in FIG. 3, the object generation / restoration unit 31C generates objects such as a desk 40 and a painting 42 provided with a drawer 41 as operation target objects. In addition to the above, the object generation / restoration unit 31C generates operation target objects such as a table, a table, and a bed.

  Further, when the player character 50 operates the operation target object based on the operation of the controller 38 by the user, the object generation / restoration unit 31C changes the position or shape of the operation target object, or changes the operation target object. delete. This will be specifically described below.

  For example, it is assumed that the player character 50 has pulled out the drawer 41 of the desk 40 in FIG. 3 and has taken the painting 42 from the wall. In this case, as illustrated in FIG. 4, the object generation / restoration unit 31 </ b> C changes the drawer 41 as the operation target object to the drawn state and deletes the painting 42 from the game screen 350.

  Furthermore, the object generation / restoration unit 31C operates the operation target object when the player character 50 performs an operation to re-operate the operation target object or return the operation target object based on the operation of the controller 38 by the user. Return to the previous state. This will be specifically described below.

  For example, when the player character 50 returns the painting 42 to the original position from the state of FIG. 4, the object generation / restoration unit 31C displays the painting 42 as the operation target object on the game screen 350 as shown in FIG. Draw again.

  Here, when the drawer 41 of the desk 40 in FIG. 4 is the above-described irreversible object, even if the player character 50 tries to return the drawer 41 to the original state, the drawer 41 does not return as shown in FIG. It is like that.

  When the drawer 41 is not an irreversible object, when the player character 50 performs an operation to return the drawer 41, the object generation / restoration unit 31C displays the drawer 41 (drawer in a state where the drawer 41 is not pulled out) as an operation target object. Draw on the game screen 350.

Object determination unit 31D
The object determining unit 31D determines whether or not the position or shape of the operation target object has changed when the non-player character 51 returns to the room (after a predetermined in-game time has elapsed) by the non-player character control unit 31B (or It is determined whether or not an irreversible object exists) or whether the operation target object has been deleted.

  For example, referring to FIG. 5, the object determination unit 31D determines that the painting 42 as the operation target object has not been deleted, and determines that there is a drawer 41 that is an irreversible object and does not return to the original state.

・ Penalty grant unit 31E
When the object determining unit 31D determines that the position or shape of the operation target object has changed (or an irreversible object exists) or the operation target object has been deleted, Penalize the user.

  For example, referring to FIG. 5, since there is a drawer 41 as an irreversible object, the penalty grant unit 31E gives a penalty to the user. In this case, as shown in FIG. 6, on the game screen 350, the non-player character control unit 31 </ b> B performs a punishment such that the non-player character 51 attacks the player character 50.

<About the game>
The game provided by the game program executed in the game apparatus 3 in the present embodiment is applied to an escape game in which the user escapes from the room while solving a mystery existing in the room (place) in confinement. The present invention is not limited to the above, and can also be applied to RPG and adventure games.

  The escape game includes a game executed in a three-dimensional space and a game executed in a two-dimensional space.

  In this embodiment, the escape game is processed at a frame rate of 60 fps (1 frame = 1/60 seconds), for example. The frame rate is not limited to this embodiment. The frame rate is determined to be 60 fps, 30 fps, etc. depending on the processing capability of the game device (hardware).

<Process flow>
Next, the process flow of the game apparatus 3 will be described.

  FIG. 7 is a flowchart showing a process flow of the game apparatus 3. These processes are executed at predetermined intervals (for example, 60 fps intervals). Note that the overall flow of the game is omitted. In addition, each process is not limited to the present embodiment, and may be executed in parallel, and the order may be changed as appropriate.

  As shown in FIG. 7, first, the object generation / restoration unit 31C determines whether or not the operation target object on the game screen 350 is operated by the player character 50 by the operation of the controller 38 by the user (step S1). .

  As a result of step S1, when it is determined that the operation target object has been operated (step S1: YES), the object generation / restoration unit 31C changes the position or shape of the operation target object, or deletes the operation target object. (Step S2). On the other hand, as a result of step S1, if it is not determined that the operation target object has been operated (step S1: NO), the object generation / restoration unit 31C waits as it is.

  Next, the object generation / restoration unit 31C determines whether or not an operation to return the operation target object to the original state (the state before the operation) is performed by the player character 50 by the operation of the controller 38 by the user (step S3). .

  As a result of step S3, when it is determined that the operation of returning the operation target object by the player character 50 has been performed (step S3: YES), the object generation / restoration unit 31C returns the operation target object to the state before the operation (step S3). S4). If the above-described irreversible object is set as the operation target object operated in step S3, the object generation / restoration unit 31C does not return the operation target object to the original state in step S4.

  Subsequently, after the process of step S4 or when it is not determined in step S3 that the player character 50 has performed an operation of returning the operation target object (step S3: NO), the object determination unit 31D displays the non-player character. It is determined whether or not the non-player character 51 has returned to the room by the control unit 31B (step S5).

  As a result of step S5, when it is determined that the non-player character 51 has returned to the room (step S5: YES), the object determination unit 31D determines whether the position or shape of the operation target object has changed, or whether the operation target object has changed. It is determined whether or not has been deleted (step S6).

  On the other hand, as a result of step S5, when it is not determined that the non-player character 51 has returned to the room (step S5: NO), the object determination unit 31D waits as it is.

  As a result of step S6, when it is determined that the position or shape of the operation target object has changed or it is determined that the operation target object has been deleted (step S6: YES), the penalty granting unit 31E A penalty is given (step S7).

  The reason for giving a penalty in this way is as follows. The purpose of the non-player character 51 is to confine the player character 50 in the room. Under such a background, when the player character 50 does not return the operation target object to the original state, the non-player character 51 determines that the player character 50 is about to escape from the room, and the non-player character 51 This is to give a punishment for attempts to escape that obstruct the above purpose.

  On the other hand, if it is determined in step S6 that the position or shape of the operation target object has changed or it has not been determined that the operation target object has been deleted (step S6: NO), the non-player character control unit 31B Then, control is performed so that the non-player character 51 is removed from the room (step S8). After this, the user can continue the puzzle solving for the player character 50 to escape from the room by operating the controller 38.

  As described above, according to the present embodiment, in order to escape from the confined room, the operation performed after the player character 50 operates the operation target object and before the non-player character 51 returns to the room. If the target object is not returned to its original state, it will be penalized. Thus, it is possible to provide a game program and a game device that can provide thrilling by giving the user a novelty and a further difficulty level in the escape game.

<Modification>
A modification in the present embodiment will be described. Even in the modified example, the above-described effects can be obtained. Note that all of the following modifications may be employed instead of or in addition to the present embodiment, and a game with higher interest can be provided by appropriately combining them.

  In the present embodiment, the drawer 41 and the painting 42 of the desk 40 are described as examples of the operation target object. However, the present invention is not limited thereto, and examples thereof include a wine bottle, a book stored in a bookshelf, and a chair. Other operation target objects may be adopted. In other words, any object that can be provided in a room is not particularly limited.

  Further, a penalty may be imposed if the operation target object is not returned to the original state in the order in which the player character 50 operates the plurality of operation target objects.

  In the present embodiment, the non-player character 51 is returned to the room in response to a failure action such as making a noise by the player character 50. However, the present invention is not limited to this. The non-player character 51 may be controlled to return to the room after a certain time has elapsed after the non-player character 51 leaves the room.
