java碰撞小球代码 js两个小球碰撞

IT技术小球

java 小球碰撞 条件是球心距离 导致"黏住"2个球相撞，2个球心在一定距离内就可以认为相撞 。
两球相撞反弹运动 if((x1-x20)(y1-y20)){ if((x1-x2=r)(y1-y2=r)){ dr1=3; dr2=1;} } if((x1-x20)(y1-y20)){ if((x1-x2=r)(y2-y1=r)){ dr1=0; dr2=2;} } if((x2-x10)
JAVA如何实现小球的弹性碰撞我没用java写过代码，所以我只说算法，代码你自己翻译下
按C的语法来：
void xiaoqiu
{
int UB=10,DB=200,LB=10,RB=200;//定义弹球范围的边界
int sh=1;//定义横向步长
int sz=1;//定义纵向步长（两步长之比决定了反弹的角度）
int x=LB,y=UB;//定义坐标
int i=10000;//循环次数（自己选择跳出手段）
while(i0)
{
i--;
x=x+sh;
if(x=RB||x=LB) sh=-sh;//碰壁后步长变反
y=y+sz;
if(y=DB||y=UB) sz=-sz;//碰壁后步长变反
(显示代码)
}
return;
}
总得来说，就是相当于横向和纵向分别处理移动、反弹的问题，碰壁后步长变为相反数

JAVA做一个作业，制作一个window框里面有三个小球碰撞，碰到边框或者小球变色加反弹，错误代码求指点没办法了 只能注册一个马甲了
