用VS写了一个下一百层的代码，出现bug。

Question

我定义了五块板子，标写有ABCDE，现在的问题是，
我的球碰到板子不会上升，会穿过，每过一波，
BE的板子可以带着球一起走，然后下一波是C的板子可以带着球走，其他的板子都会穿过
下面是代码，请大佬看一下谢谢

 void withoutinput()  //输入无关
{
    static int speed = 0;
    static int k = 0;

    speed++;
    for(int i=0;i<barNumber;i++)
    {

        if( ball_y - (bar_y[i]-bar_high/2-radius) < 5 && ball_y - (bar_y[i]-bar_high/2-radius) > -5) //改这里，因为不一定刚刚好相等，所以会错过
        {
            if(ball_x>=bar_x[i]-bar_width/2 && ball_x<=bar_x[i]+bar_width/2)
            {
                ball_v = -5;
                break;
            }
            else
                ball_v = 1;
        }
    }
