我正在使用 starling-framework 开发游戏。我的问题是当我将一组元素添加到juggler
.
目前我的计划是
while(some_condition){ //allocate a set of tween
var tween=createTween(tweenCount++);
tween.onComplete=function(){
tweenCount--;
}
}
function checkComplete(){
if(tweenCount==0)
doStuff();
else
setTimeout(checkComplete,1000);
}
还有更好的解决方案吗?谢谢你的时间!
更新
写一个简单的类来解决这个问题,似乎更好
public class TweenMonitor
{
public function TweenMonitor()
{
throw new Error('static class');
}
private static var refDict:Dictionary = new Dictionary();
public static function monit(tweens:Vector.<Tween>,onAllFinish:Function,id:String='$default$'):void
{
for (var i:int = 0; i < tweens.length; i++)
{
var tween:Tween = tweens[i];
if (tween == null)
continue;
if (refDict[id] == null) {
refDict[id] = 1;
}else
refDict[id]++;
tween.addEventListener(Event.REMOVE_FROM_JUGGLER,function (e:Event):void
{
refDict[id]--;
if (refDict[id] == 0)
onAllFinish && onAllFinish();
});
}
}
}
