我想移动阵列中的所有对象产生体育场波浪效果,我该怎么做? 我想根据舞台上的y值移动对象......我的所有正方形都是50x50。我想把它们向上移动然后向下移动它们。 以下是我的代码,请给我建议。谢谢!
import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;
var t1:Timer = new Timer(100, 0);
var index:int = 0;
t1.addEventListener(TimerEvent.TIMER, ping);
t1.start();
var array:Array = new Array();
addToArray();
function addToArray():void {
for(var i=0; i<10; i++) {
array[i] = new Sq();
array[i].x = i*50 + 50;
array[i].y = 100;
addChild(array[i]);
}
}
function ping(e:TimerEvent) {
if(index < array.length){
moveUp(array[index]);
index ++;
}
}
function moveUp(sq:Sq):void{
var tweenRight:Tween = new Tween(sq,"y",None.easeOut, sq.y, sq.y - 50, 1, true);
tweenRight.addEventListener(TweenEvent.MOTION_FINISH, moveDown);
}
function moveDown(e:TweenEvent):void {
//what to put here?
//or this is not the right way to do this?
}
答案 0 :(得分:1)
您需要在moveDown函数中抓取补间对象并应用补间动画(增加y)。
function moveDown(e:TweenEvent):void {
var sq:Sq = Sq(e.target.obj);
var tweenDown:Tween = new Tween(sq,"y",None.easeOut, sq.y, sq.y + 50, 1, true);
if (Sq(e.target.obj) === array[array.length - 1]) {
trace("this is the last tween down");
tweenDown.addEventListener(TweenEvent.MOTION_FINISH, lastTweenFinish);
}
}
function lastTweenFinish(e:TweenEvent):void {
trace("DONE");
}
还有一件事是为什么在moveUp函数中使用Timer t2。
