AS2:setInterval只调用一次

Question

我有以下函数和间隔,它被调用一次但后来再也没有.谁能明白为什么？

    function tweenArrow() {
        trace("called");
        var TweenAX:Tween = new Tween(circle.current.arrowHead, "_x", mx.transitions.easing.Strong.easeOut, circle.current._x, Stage.width/2, 2, true);
        var TweenAY:Tween = new Tween(circle.current.arrowHead, "_y", mx.transitions.easing.Strong.easeOut, circle.current._y, Stage.height/2, 2, true);
    }
    setInterval(tweenArrow(),2000);

Answer 1

您正在调用您的函数而不是引用setInterval.尝试

setInterval(tweenArrow,2000);
