删除小球的方法
function updateBalls(){
/*更新小球属性*/
for(var i=0;i<balls.length;i++){
balls[i].x += balls[i].vx;
balls[i].y += balls[i].vy;
balls[i].vy += balls[i].g;
/*下边缘检测*/
if(balls[i].y >= Window_Height-Radius){
balls[i].y = Window_Height-Radius;
balls[i].vy = - balls[i].vy*0.75;
}
/*右边缘检测*/
if(balls[i].x >= Window_Width+Radius && balls[i].x+Radius >= 0){
delete aBall;//删除小球
}
}
}可以用delete删掉出界的小球吗？
