我有一个可以拖入另一个对象的对象。我已经为碰撞设置了一个命中测试。当发生碰撞时,我想进入下一帧但是,我必须单击可拖动对象才能执行此操作。我想立即移动到下一帧而不点击。无论如何要解决这个问题吗?
我的意思是在我拖动了对象以创建碰撞后,我需要再次单击该对象以进入下一帧。我不想再次点击该对象我希望它在发生碰撞时转到下一帧。
这是我的代码
bottle.buttonMode = true;
bottle.addEventListener(MouseEvent.MOUSE_DOWN, drag);
bottle.addEventListener(MouseEvent.MOUSE_UP, drop);
function collision():void{
if(bottle.hitTestObject(hit)){
nextFrame();
}
}
function drag(e:MouseEvent):void{
bottle.startDrag();
collision();
}
function drop(e:MouseEvent):void{
bottle.stopDrag();
}

将collision()
更改为事件监听器并将其附加到bottle
。

您应该在drop
之后检查是否发生了碰撞,而不是drag
的开头:
function collision():void{
if(bottle.hitTestObject(hit)){
nextFrame();
}
}
function drag(e:MouseEvent):void{
bottle.startDrag();
}
function drop(e:MouseEvent):void{
bottle.stopDrag();
collision();
}

试试这个(改编自Gary Rosenzweig):
bottle.buttonMode = true;
bottle.addEventListener( MouseEvent.MOUSE_DOWN, startBottleDrag );
stage.addEventListener( MouseEvent.MOUSE_UP, stopBottleDrag );
function collision():void {
if( bottle.hitTestObject( hit ) ) {
stopBottleDrag();
nextFrame();
}
}
// to keep bottle location as it is when clicked
var clickOffset:Point = null;
function startBottleDrag( e:MouseEvent ) {
clickOffset = new Point( e.localX, e.localY );
bottle.addEventListener( Event.ENTER_FRAME, dragBottle );
}
function stopBottleDrag( e:MouseEvent = null ) {
clickOffset = null;
bottle.removeEventListener( Event.ENTER_FRAME, dragBottle );
}
function dragBottle( e:Event ) {
bottle.x = mouseX - clickOffset.x;
bottle.y = mouseY - clickOffset.y;
collision();
}
