本文介绍了想用C / C ++移动球的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
#include<graphics.h>
#include<conio.h>
#include<alloc.h>
#include<dos.h>
#include<stdlib.h>
void *ball;
void image()
{
setcolor(RED);
setfillstyle(SOLID_FILL,RED);
fillellipse(10,10,10,10);
ball=malloc(imagesize(0,0,20,20));
getimage(0,0,20,20,ball);
cleardevice();
}
void main(void)
{
int gmode,gdriver=DETECT;
initgraph(&gdriver,&gmode,"c:\\tc\\bgi");
int l=getmaxx()/2,r=0,t=0,b=0;
int x=1,y=1;
int s=0,key=0;
int xstep=1,ystep=1;
image();
setbkcolor(GREEN);
while(key!=27)
{
while(!kbhit())
{
outtextxy(250,350,"");
setcolor(7);
putimage(l,t,ball,XOR_PUT);
delay(5);
putimage(l,t,ball,XOR_PUT);
if(l>=getmaxx()||l<=0)
{
x*=-1;sound(1000);
s=0;xstep=x*(random(4)+1);
ystep=y*(random(3)+1);
if(l<=0)
l=0;
else
l=getmaxx();
}
if(t>=getmaxy()||t<=0)
{
y*=-1;sound(1000);
s=0;ystep=y*(random(4)+1);
xstep=x*(random(3)+1);
if(t<=0)
t=0;
else
t=getmaxy();
}
l+=x+xstep;
t+=y+ystep;
s++;
if(s==5)
{
nosound();
}
}
key=getch();
}
closegraph();
}
这个球随机移动,但我想把这个球向左(中),右(中),向上(中),向下移动(中心)像钻石<>
This ball moves randomly, but I would like to move this ball just left(center), right(center), up(center), down(center) like diamond <>
推荐答案
这不是问题。你使用随机
,然后抱怨球随机移动。这没有道理。 Obvious上尉说:如果你想以某种方式移动它,就这样移动它。 :-)
-SA
This is not a question. You userandom
and then complain that the ball moves randomly. It makes no sense. Captain Obvious says: if you want to move it in certain way, move it in this way. :-)
—SA
您可以使用第一个随机数来决定哪个您要移动的轴。然后根据第一个数字,执行水平或垂直移动。
You might use a first random number to decide along which axis you want to move. Then according to that first number, you execute either the horizontal or the vertical move.
