AS2：动态补间标识符

我如何动态设置补间标识符。我尝试过 eval 但它说我需要在赋值运算符左侧有一个变量。这是我尝试过的：

eval ("TweenAX" + circle.current.arrowHead.count) = new Tween(circle.current.arrowHead, "_x", mx.transitions.easing.Strong.easeOut, circle.current._x, Stage.width/2, 2, true);
eval ("TweenAY" + circle.current.arrowHead.count) = new Tween(circle.current.arrowHead, "_y", mx.transitions.easing.Strong.easeOut, circle.current._y, Stage.height/2, 2, true);

干杯

How do i go about setting the tween identifier dynamically. I have tried eval but it says I need a variable on the left of the assignment operator. here's what I tried:

eval ("TweenAX" + circle.current.arrowHead.count) = new Tween(circle.current.arrowHead, "_x", mx.transitions.easing.Strong.easeOut, circle.current._x, Stage.width/2, 2, true);
eval ("TweenAY" + circle.current.arrowHead.count) = new Tween(circle.current.arrowHead, "_y", mx.transitions.easing.Strong.easeOut, circle.current._y, Stage.height/2, 2, true);

Cheers

我不是 100% 确定我理解您想要实现的目标，但我认为您正在寻找括号语法：

this["TweenAX" + circle.current.arrowHead.count] = new Tween(circle.current.arrowHead, "_x", mx.transitions.easing.Strong.easeOut, circle.current._x, Stage.width/2, 2, true);
this["TweenAY" + circle.current.arrowHead.count] = new Tween(circle.current.arrowHead, "_y", mx.transitions.easing.Strong.easeOut, circle.current._y, Stage.height/2, 2, true);

这将在 this 上创建两个名为TweenAXN 和 TweenAYN，其中 N 是 circle.current.arrowHead.count 的值

I'm not 100% sure I understand what you are trying to achieve, but I think you're looking for the bracket syntax:

this["TweenAX" + circle.current.arrowHead.count] = new Tween(circle.current.arrowHead, "_x", mx.transitions.easing.Strong.easeOut, circle.current._x, Stage.width/2, 2, true);
this["TweenAY" + circle.current.arrowHead.count] = new Tween(circle.current.arrowHead, "_y", mx.transitions.easing.Strong.easeOut, circle.current._y, Stage.height/2, 2, true);

This will create two properties on this named TweenAXN and TweenAYN where N is the value of circle.current.arrowHead.count
