Description

  The present invention relates to a game device and a display control program executed in the game device, and more particularly to a display control program in a game device having a display screen as a virtual game space.

  As one of action games, a player (player) operates an object (or character) appearing in the game to move the object and a moving object (or object) to be played by the object in the game space. There is. For example, there is a game in which a racket prepared in advance or a racket handwritten by a player is used as an object, and the player operates the racket to strike back a ball.

When handwriting input is performed in such a game, it is realized by displaying an image previously input by a player using a handwriting input device (see Patent Document 1).

And an external storage medium that stores game programs and data (including video and music data) as information resources for electronic games It is configured to include a memory) 8.

  The control unit 7 executes a game program stored in the external storage medium 8, controls the entire system, and an image processing circuit that generates image information based on information resources, and is necessary for the CPU 71 to perform processing. The RAM 73 that stores programs and data, the ROM 72 that stores programs and data that operate first prior to the game program when the game apparatus 100 is activated, and other game apparatuses transmit and receive information. A communication interface 77 serving as an information transmission / reception circuit that receives information on an operation object operated by another user by communication and transmits information on an operation object operated by the operation button 5 or the touch panel 4 to another game device by communication; , Objects and objects to play A sound controller 76 as sound effect generating means for generating sound effects according to the behavior of the moving body (ball), and a display for performing control for displaying the object and the moving body (ball) on the screen of the main monitor 2 A main monitor graphic controller 74 as a control circuit, and an operation unit monitor graphic controller 75 that controls the object and the moving body (ball) to display an image on the screen of the operation unit monitor 3. Has been.

  As shown in FIG. 2, the main monitor graphic controller 74, the operation unit monitor graphic controller 75, and the CPU 71 include an operation button data input unit 101, a touch panel data input unit 102, a pointer position control unit 103, a gauge level control unit 104, The game image generation unit 105, the pointer image generation unit 106, the gauge image generation unit 107, the operation unit background image generation unit 108, the main monitor image generation unit 109, and the operation unit monitor image generation unit 110 are configured. The unit 109 is connected to the main monitor 2, and the operation unit monitor image generation unit 110 is connected to the operation unit monitor 3.

  The main monitor 2, the operation unit monitor 3, the main monitor graphic controller 74, and the operation unit monitor graphic controller 75 may each be a single monitor or graphic controller. The main monitor image generation unit 109 and the operation unit monitor The image generation unit 110 may also be a single image generation unit as a function.

  In the configuration of the game apparatus 100, a display control program used for control for displaying a game image using the display screens of the main monitor 2 and the operation unit monitor 3 as a virtual game space will be described below.

  FIG. 3 is a flowchart for explaining the processing of the display control program according to the present invention.

  First, when the game apparatus 100 is activated, a handwriting racket (line smasher) 40 is formed as a figure of an object for each predetermined distance by a continuous input of a pointing device, for example, a touch pen on the player's touch panel 4, as shown in FIG. The constituting racket figures 42, 44, 46,... Are arranged (step S1). These racket figures 42 to 46 are arranged at equal intervals along the direction in which the touch pen is moved from the coordinates at which the touch pen is first touched on the touch panel 4. Then, ID (Identity) numbers are set in order for the racket figures 42, 44, 46 and the like arranged at equal intervals (step S2). For example, ID = 0 is set for the racket graphic 42, ID = 1 is set for the racket graphic 44, and ID = 2 is set for the racket graphic 46.

When the handwritten racket 40 is completed, it is registered as an operation target object in the game control as a polygon or sprite as a racket object, and the game is started (step S3). The CPU 71 performs control for placing the handwritten racket 40 and the ball 50 at the initial position of the display screen (virtual game space) (step S4). At this time, the ball may be moved in the initially set direction from the initial position, or may be moved after waiting for the racket to contact. Thereafter, as a process mainly performed by the CPU 71, it is determined whether or not there is an operation input, that is, whether or not the operation button 5 or the touch panel 4 is operated by the player's operation (step S5). Next, with the execution of the program, the movement position of the handwritten racket 40 and the generation of the movement image are executed (step S6). After that, it is determined whether or not the ball (pack) 50, which is a moving object to be played by the handwritten racket (object) 40, has come into contact with the handwritten racket 40, that is, whether or not both have collided (step S7). . Whether or not the ball and the racket have been hit is determined based on whether or not the display area of the ball or the racket or an area (coordinates) obtained by simplifying the display area is overlapped. When the ball 50 and the handwritten racket 40 come into contact with each other, for example, as shown in FIG. 4, among the racket figures 42, 44, 46 of the handwritten racket 40, Straight lines (segments) A and B connecting the representative points (center points) of the adjacent racket figures 42 and 46 are calculated (step S8).
Next, an angle that is ½ of the angle at which the straight line A and the straight line B intersect is calculated, and the straight line A or the straight line B is set to the angle (½ angle) around the intersection of the straight line A and the straight line B A straight line C that is equal to the straight line that has been rotated by the distance is calculated (step S9). That is, the straight line C may be calculated not as a process of rotating the straight line A or the straight line B but as a straight line passing through the intersection of the straight line A and the straight line B and the midpoint of the straight line A and the straight line B. This eliminates the process of accurately calculating the contact position between the ball 50 and the handwritten racket 40, thereby enabling a process that is not affected by the shape of the handwritten racket 40. A straight line connecting either one of the representative points of the racket graphic 42 and the racket graphic 46 may be used as the straight line C with respect to the racket graphic 44. The straight line C is the same as the racket graphic 44 with which the ball 50 collides. Any straight line calculated based on a straight line connecting the representative points of the racket figure adjacent thereto may be used.

  Next, the angle θ between the movement vector Vb of the ball 50 and the straight line C is calculated (step S10), and the relative velocity between the ball 50 and the handwritten racket 40 is calculated (step S11). Since step 5 and subsequent steps in the flowchart of FIG. 3 are repeatedly executed at regular time intervals (for example, every 1/60 seconds), the relative speed between the ball 50 and the handwritten racket 40 is determined in the collision direction during the regular time. The distance traveled is calculated respectively.

  Next, it is determined whether or not the color change flag is set (step S12). When the color change flag is not set, the process proceeds to step S13. When the color change flag is set, the process is set to step S15. Migrate to This determines whether the ball hitting the racket has hit after hitting the opponent's racket, which will be described later, or whether the ball hit by the player bounces back without hitting the opponent's racket.

  In step S13, it is determined whether or not the angle θ is larger than a predetermined value (specified value). If the angle θ is larger than the predetermined value, whether or not the relative speed is larger than a predetermined value (specified value). Is determined (step S14). For example, it is determined whether or not it hits the vertical direction. That is, in steps S13 and S14, an evaluation value is calculated from the calculated relative speed and angle, and the image of the handwritten racket 40 after the collision is affected by the following processing according to the calculated evaluation value. Yes.

For example, as shown in FIG. 6, when the evaluation value when the ball 50 collides with the handwritten racket 40 exceeds a specified value, the racket graphic 42 positioned on both sides of the racket graphic 44 hit by the ball 50 in step S17. 46, the number of racket figures located next to each other is calculated as the number of IDs. Then, the racket figures 42 and the subsequent ones with a small number of racket figures arranged on both sides of the racket figure 44 with which the ball 50 collides are deleted. In other words, the racket graphic belonging to the region where the length from the collision point to the end of the racket graphic 42 or 46 is short is erased from the handwritten racket 40 based on the collision point (racquet graphic 44). The racket graphic may be erased as a racket graphic belonging to an area where the length from the collision point to the end of the racket graphic 42 or 46 is reversed by reversing the determination criteria.
As a specific image, as shown in FIG. 7, the evaluation value obtained from the relative speed and the angle θ between the ball 50 and the handwritten racket 40 exceeds the specified value, and the ball 50 is reflected from the handwritten racket 40. Then, a part of the image of the handwritten racket (line smasher) 40 is erased.
When only the sequence affecting the handwritten racket is taken out from FIG. 3, for example, as shown in FIG. 8, an evaluation value is calculated based on the moving speed and angle of the handwritten racket 40 and the ball 50 (step S201). It is determined whether or not the value exceeds the specified value (step S202). When the evaluation value exceeds the specified value, the shorter one (region) from the collision part (collision point) to the end of the handwritten racket 40 is determined. Erasing is performed (step S203). This handwritten racket sequence is executed until the game ends (step S6).

On the other hand, in the processing of steps S13 and S14 shown in FIG. 3, the angle θ is smaller than the predetermined value (specified value), the relative speed is smaller than the predetermined value (specified value), and the evaluation value exceeds the specified value. 9 and 10, even if the ball 50 collides with one handwritten racket 40 of the two handwritten rackets 40 arranged in parallel to each other, the ball 50 is reflected from the handwritten racket 40. Just do it.
Similarly, as shown in FIGS. 11 and 12, when the ball 50 collides with the handwritten racket 40 arranged along the longitudinal direction of the display screen, the evaluation value determined from the relative angle and the angle exceeds the specified value. If not, the ball 50 will only reflect from the handwritten racket 40.

  When the evaluation value determined from the relative speed and angle θ between the ball 50 and the handwritten racket 40 does not exceed the prescribed value, the movement position of the ball 50 corresponding to the reflection angle and relative speed of the handwritten racket 40 and the ball 50 is calculated. The ball 50 is placed at a predetermined position according to the value (step S15). Thereafter, a process of setting a color change flag for changing the color of the ball 50 to a predetermined color is executed (step S16).

  Next, it is determined whether or not the ball 50 has entered the goal of the player (step S19). When the ball enters the goal set on the player's side, the point is decremented (step S20), and the ball is When the goal is not entered, it is determined whether or not the ball 50 has entered the goal set on the opponent's side (step S21). When the ball 50 is not in the opponent's goal, as the opponent's game processing, for example, when the ball 50 hits the handwritten racket 40, the color of the ball 50 is changed to another color and the color change flag is changed. Is performed (step S22), and the process returns to step S3.

  On the other hand, when the ball 50 enters the opponent's goal, points are added (step S23), and it is determined whether or not the game is over (step S24). If the game is not over, the process proceeds to step S22. When the game is over, the game is terminated and the processing in this routine is terminated.

  Further, when obtaining the evaluation value, if the movement vector Vb of the ball 50 and the vector Vr of the handwritten racket 40 are obtained and the deceleration constant is P, the evaluation value can be obtained as θ · (Vb−Vr · P). This evaluation value is the highest when the ball 50 collides with the handwritten racket 40 and the approach angle is close to vertical, and when the ball 50 and the handwritten racket 40 collide with each other at high speed.

  Also, instead of erasing a part of the image of the handwritten racket 40 when the evaluation value is obtained from the relative speed and angle of the handwritten racket 40 and the ball 50 and the evaluation value exceeds a specified value, The part can also be deformed. Further, instead of the evaluation value, the number of collisions between the handwritten racket 40 and the ball 50 is measured, and a process of erasing a part of the image of the handwritten racket 40 when the number of collisions exceeds a specified number may be adopted. it can.

  Specifically, as shown in FIG. 13, the number of collisions is measured at the time of collision between the handwritten racket 40 and the ball 50, and it is determined whether or not the number of collisions exceeds a specified number (step S301). When the number of times is exceeded, a process of deleting the shorter one (region) from the collision part (collision point) to the end of the handwritten racket 40 is executed (step S302).

  Further, as shown in FIG. 14, when the handwritten racket 40 and the ball 50 collide, the moving speed and the angle θ of the handwritten racket 40 and the ball 50 are obtained, and the evaluation value is calculated from this calculated value (step S401). Then, it is determined whether or not the evaluation value exceeds the specified value (step S402). When the evaluation value exceeds the specified value, it is determined whether or not the number of collisions exceeds the specified number (step S403). When the specified number of times is exceeded, a process of deleting the shorter one (region) from the collision part to the end of the handwritten racket 40 is executed (step S404).

  Furthermore, as shown in FIG. 15, when the handwritten racket 40 and the ball 50 collide, the moving speed and the angle θ of the handwritten racket 40 and the ball 50 are calculated, and an evaluation value is calculated from the calculated value (step S501). It is determined whether or not the evaluation value exceeds a specified value (step S502). When the evaluation value exceeds the specified value, the vicinity of the collision portion of the handwritten racket 40 is determined according to the evaluation value or a separately calculated impact of the collision. Deformation (step S503). For example, the relative moving direction and moving speed are calculated from the moving speed and the angle θ of the handwritten racket 40 and the ball 50 at the time of collision, and a distance corresponding to the moving speed is calculated with respect to this moving direction. A new handwritten racket having a shape obtained by moving the racket figure 44 hit by the ball is set.

  According to the present embodiment, when the handwriting racket 40 and the ball 50 collide, the handwriting racket 40 is affected according to the state of the collision. Therefore, the player not only hits the ball 50 but also against the handwriting racket 40. Since the game is played in consideration of influence and the monotonous operation of hitting back is an important game, the range of games (how to play) can be expanded. In addition, whatever the shape of the handwritten racket, the angle at which it collided with the ball can be obtained with a certain degree of accuracy with a simple calculation. Can be reduced.
