1. Display of the final effect
The effect picture is as follows:
Draw a static bezel
The code is as follows:
# include#include#define High 480 / / Game screen size # define Width 640 int ball_x,ball_y;// / global variable coordinates of the ball int ball_vx,ball_vy;// speed of the ball, radius of the ball, central coordinates of the int bar_x,bar_y;// bezel, height and width of the int bar_high,bar_width;// bezel / / the left and right upper and lower position coordinates of the bezel void startup () / / data initialization {ball_x=Width/2; ball_y=High/2; ball_vx=1; ball_vy=1; radius=20; bar_high=High/20; bar_width=Width/5; bar_x=Width/2; bar_y=High-bar_high/2; bar_left=bar_x-bar_width/2; bar_right=bar_x+bar_width/2 Bar_top=bar_y-bar_high/2; bar_bottom=bar_y+bar_high/2; initgraph (Width,High); BeginBatchDraw ();} void clean () / / display screen {setcolor (BLACK); / / draw black lines, black filled circle setfillcolor (BLACK); fillcircle (ball_x,ball_y,radius); bar (bar_left,bar_top,bar_right,bar_bottom) / / draw black, black filled bezel} void show () / / display screen {setcolor (YELLOW); / / draw yellow line, green filled circle setfillcolor (GREEN); fillcircle (ball_x,ball_y,radius); bar (bar_left,bar_top,bar_right,bar_bottom); / / draw yellow, green filled bezel FlushBatchDraw (); Sleep (3) } void updateWithoutInput () / / updates independent of user input {ball_x=ball_x+ball_vx; ball_y=ball_y,ball_vy;// update ball coordinates if ((ball_x=Width-radius)) ball_vx=-ball_vx; if ((ball_y=High-radius)) ball_vy=-ball_vy } void updateWithInput () / / updates related to user input {} void gameover () {EndBatchDraw (); closegraph ();} int main () {startup (); / / initialization of data while (1) {clean (); / / clear updateWithoutInput () of previously drawn content; / / update updateWithInput () that is not related to user input / / update show () related to user input; / / display new screen}}
The effect picture is as follows:
3. Control bezel
The code is as follows:
# include#include#define High 480 / / Game screen size # define Width 640 int ball_x,ball_y;// / global variable coordinates of the ball int ball_vx,ball_vy;// speed of the ball, radius of the ball, central coordinates of the int bar_x,bar_y;// bezel, height and width of the int bar_high,bar_width;// bezel / / the left and right upper and lower position coordinates of the bezel void startup () / / data initialization {ball_x=Width/2; ball_y=High/2; ball_vx=1; ball_vy=1; radius=20; bar_high=High/20; bar_width=Width/5; bar_x=Width/2; bar_y=High-bar_high/2; bar_left=bar_x-bar_width/2; bar_right=bar_x+bar_width/2 Bar_top=bar_y-bar_high/2; bar_bottom=bar_y+bar_high/2; initgraph (Width,High); BeginBatchDraw ();} void clean () / / display screen {setcolor (BLACK); / / draw black lines, black filled circle setfillcolor (BLACK); fillcircle (ball_x,ball_y,radius); bar (bar_left,bar_top,bar_right,bar_bottom) / / draw black, black filled bezel} void show () / / display screen {setcolor (YELLOW); / / draw yellow line, green filled circle setfillcolor (GREEN); fillcircle (ball_x,ball_y,radius); bar (bar_left,bar_top,bar_right,bar_bottom); / / draw yellow, green filled bezel FlushBatchDraw (); Sleep (3) } void updateWithoutInput () / / updates independent of user input {/ / the bezel collides with the ball, and the ball bounces if (ball_y+radius > = bar_top) & & (ball_y+radius=bar_left) & & (ball_x0) {bar_x=bar_x-15;// position moves left bar_left=bar_x-bar_width/2; bar_right=bar_x+bar_width/2) } if (input=='d'&&bar_right0) {bar_y=bar_y-15;// position move left bar_top=bar_y-bar_high/2; bar_bottom=bar_y+bar_high/2;} if (input=='s'&&bar_bottom
