Flash Actionscript +检测边缘碰撞

我有两个圆形物体。我试图在圆圈触摸时立即检测到。当一个圆圈到达另一个圆圈的中心时,轨迹会检测到碰撞,但我希望一旦圆圈接触就会检测到碰撞。

我的两个符号是coin_mc和mugbounds_mc。

function checkHitArea(evt:Event)
{

 if (coin_mc.hitTestPoint(mugbounds_mc.x,mugbounds_mc.y, true)) {
  coin_mc.x=-1;
  coin_mc.y=-1;

                trace("Hit Mug"); // Is triggered when coin_mc reaches center of mugbounds_mc
        }
        else
        {
                trace("Didn't Hit Mug");
        }
}

试试这个:

addEventListener(Event.ENTER_FRAME, checkHitArea)

function checkHitArea(e:Event) 
{
    a.x += 2;
    if (a.hitTestPoint(b.x,b.y, false)) 
    { 
        // do our in-circle check
        if((a.x - b.x) * 2 + (a.y - b.y) * 2 <= (a.width/2 + b.width/2) * 2)
        {
            trace("hit");
        }
    }
    else
    {
        trace("Didn't Hit Mug");
    }
}

我将您的影片剪辑重命名为a和b。
