AS2：动态补间标识符

Question

如何动态设置补间标识符。我试过eval，但它说我需要在赋值运算符的左边有一个变量。这是我试过的：

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

Answer 1

我并非100％确定我理解您要实现的目标，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);

这将在名为this和TweenAXN的{​​{1}}上创建两个属性，其中TweenAYN是N的值
