Actionscript 3 can'；t在flash actionscript中存储对象x和y坐标

似乎无法使用此代码存储坐标

    var collisions:Array = _collisionList.checkCollisions();
    if(collisions.length)
    {
        var tempX:Number = 0;
        var tempY:Number = 0;

        _speedX = 0;
        _speedY = 0;
        _wheel.vx = 0;
        _wheel.vy = 0;

        if(tempX==0 || tempY== 0){
            trace(_wheel.x+" "+_wheel.y);
            if(_speedX>0) tempX = _wheel.x - .5;//GOING RIGHT
            if(_speedX<0) tempX = _wheel.x + .5;

            if(_speedY>0) tempY = _wheel.y - .5;//GOING DOWN
            if(_speedY<0) tempY = _wheel.y + .5;

            trace(tempX+" "+tempY);
        }

        //_wheel.x = tempX;
        //_wheel.y = tempY;
    }
    else{

        //_wheel.vy += GRAVITY;

        //Moves Hero
        _wheel.vx += _speedX;
        _wheel.vy += _speedY;

        //Slows down hero's motion.
        _wheel.vy *= FRICTION;
        _wheel.vx *= FRICTION;

        //Updates hero's position.
        _wheel.x += _wheel.vx;
        _wheel.y += _wheel.vy;

        if(_wheel.x > stage.stageWidth) _wheel.x = stage.stageWidth;
        if(_wheel.x < /*0*/stage.stageWidth*-1) _wheel.x = stage.stageWidth*-1
        if(_wheel.y > stage.stageHeight - (_wheel.height >> 1) )//reset ball.
        {
            //_wheel.y = 10;
            //_wheel.x = 30;
            //_wheel.vx = _wheel.vy = 0;
        }

    }

这就是speedX和speedY值的变化方式

您的值未被存储的原因是因为从未满足

if

条件：（请参阅我的代码注释）

\u speedX=0//你不想在这里设置这个
_速度=0//还是这个
_车轮vx=0//可能也不是这样
_wheel.vy=0；//还是这个
如果（tempX==0 | | tempY==0）{
轨迹（_-wheel.x++u-wheel.y）；
//由于上面您刚刚将_speedX设置为0，因此将不满足此条件。
如果（_speedX>0）tempX=_wheel.x-.5；
//由于上面您刚刚将_speedX设置为0，因此将不满足此条件。
如果（_speedX0）tempY=_wheel.y-.5；
//由于上面您刚刚将_speedY设置为0，因此将不满足此条件。
如果（| speedy不能做布尔运算或类似的运算，如果我正确地阅读了你的代码-必须做
tempX==0 | | tempY==0
将它从if（（tempX | | tempY）==0）更改为if（tempX==0 | | tempY==0）仍然无法存储坐标。您是否遇到了错误，或者只是意外行为？错误/行为是什么？此外，出于好奇，如果
，为什么会这样做？您只需将它们设置为0-这将始终是真的。
\u wheel.x
，
\u wheel.vx
和
\u wheel.y
，
\u wheel.vy
是否应该不同，或者这是一个典型的问题o？在if语句之前，您正在将
\u speedX
和y设置为0，因此在执行
if（\u speedX>0）
