在iOS上显示Starling-触摸事件处理程序“死亡" [英] Starling on iOS - Touch event handler "dies off"

问题描述

我有一种在Box2d中向球施加力的方法.

I have a method that applies force to a ball in Box2d.

在台式机上进行本地测试可以正常运行，但在iPad(ios7)上可以正常运行 该方法仅执行到一半！

Testing it locally on desktop it works fine, but on iPad (ios7) the method get executed only until the half!

我从来没有遇到过这种奇怪的错误，这是怎么回事:

I never came accross such a weird error, what is wrong here:

function onTouch(e:TouchEvent) {

    var touch:Touch = e.getTouch(this) as Touch;



    if (touch && touch.phase == TouchPhase.ENDED) {


        //do something

        _debugT.text = "works";


            var mouseX_m:Number = touch.globalX;
    var mouseY_m:Number = touch.globalY;

    _debugT.text = "stops here...";


    var xDiff:Number = mouseX_m - (_whiteBall.GetPosition().x * WORLD_SCALE);
    var yDiff:Number = mouseY_m - (_whiteBall.GetPosition().y * WORLD_SCALE);


    var angle:Number = Math.atan2(yDiff, xDiff);
    var angleDeg:Number = angle * 180 / Math.PI;



    _debugT.text = "never gets executed"



    var len = Math.sqrt((xDiff * xDiff) + (yDiff * yDiff));






    var vx = len * Math.cos(angle);
    var vy = len * Math.sin(angle);



    var vel = _whiteBall.GetLinearVelocity();

    vel.x += (vx * 5);
    vel.y += (vy * 5);



        var force = new b2Vec2(vel.x, vel.y);
        _whiteBall.SetAwake(vel);
        _whiteBall.SetLinearVelocity(force);





    }

}

推荐答案

对我来说，它看起来像Multitouch.inputMode = MultitouchInputMode.GESTURE;导致此问题.

To me it looks like Multitouch.inputMode = MultitouchInputMode.GESTURE; causes this problem.

我遇到了同样的问题，并注释了这一行，现在可以了.

I had the same issue and commented out this line and it works now.
