C语言基于ege图形库的图片碰撞检测

WSAD移动有碰撞的话会显示一个原点

我用的是两张80*80的图片用其他的图片的话自己改代码把图片改名成1.png和 2.png

就是这两张图片

#include<graphics.h>
#include<windows.h>
#include<stdio.h>
int xx,yy;
int wanjiax=20,wanjiay=120;
SMALL_RECT z,f,naka;
bool panduan(PIMAGE img,PIMAGE img2)
{bool zf=0;if(wanjiay<=200) {zf=1;z.Left=wanjiax;z.Top=wanjiay;z.Right=wanjiax+80;z.Bottom=wanjiay+80;f.Left=100;f.Top=200;f.Right=180;f.Bottom=280;}else {zf=0;z.Left=100;z.Top=200;z.Right=180;z.Bottom=280;f.Left=wanjiax;f.Top=wanjiay;f.Right=wanjiax+80;f.Bottom=wanjiay+80;}//主副框赋值完成if(f.Top>z.Bottom||f.Right<z.Left||f.Left>z.Right||f.Bottom<z.Top) return 0;//排掉没有相交完成color_t *zh,*fh;if(f.Right<=z.Right) {//如果副框在框左边 包含中线naka.Left=z.Left;naka.Top=f.Top;naka.Right=f.Right;naka.Bottom=z.Bottom;for(int j=naka.Top;j<=naka.Bottom;j++){if(zf) {zh=getbuffer(img);fh=getbuffer(img2);}else {fh=getbuffer(img);zh=getbuffer(img2);}fh+=(j-naka.Top)*80;zh+=(j-z.Top)*80;fh+=(naka.Left-f.Left);for(int i=naka.Left;i<=naka.Right;i++,fh++,zh++){if((*zh)!=0&&(*fh)!=0) {xx=i;yy=j;return 1;}}}}else {//如果副框在框右边 不含中线naka.Left=f.Left;naka.Top=f.Top;naka.Right=z.Right;naka.Bottom=z.Bottom;for(int j=naka.Top;j<=naka.Bottom;j++){if(zf) {zh=getbuffer(img);fh=getbuffer(img2);}else {fh=getbuffer(img);zh=getbuffer(img2);}fh+=(j-naka.Top)*80;zh+=(j-z.Top)*80;zh+=(naka.Left-z.Left);for(int i=naka.Left;i<=naka.Right;i++,zh++,fh++){if((*zh)!=0&&(*fh)!=0) {xx=i;yy=j;return 1;}}}}
}
main()

}
