如何使用动画 HAXE/OPENFL 显示形状

如何解决如何使用动画 HAXE/OPENFL 显示形状

这是我创建形状和添加到数组的代码

'''

var sprite:Sprite;
var step = 0.5;

var colors = [
    0xFFFF0B,0xFF700B,0x4286f4,0xf441e8,0x8dff6d,0x41ccc9,0xe03375,0x95e032,0x77c687,0x43ba5b,0x0ea3ba

    // fallDown();
    // super();
}

    return sprite;
}

    var rectangle = new Sprite();

    sprite.y += step;

public function fallDown() {

'''

我有一个这样的数字代码。 和我的主类中的代码

'''

public function new() {
    super();
    model.fallDown();
    showInterval();
    clickBtn();
}

private function showInterval() {
    var timer = new Timer(1000);
    timer.run = anim.bind();
}

private function anim() {
    var getArr = model.getfigures();
    for (i in 0...num) {
        addChild(getArr[i]());
    }
}

private function clickBtn() {
    var plus = browser.document.getElementById("increasefigure");
    plus.onclick = (event) -> num++;
    var minus = browser.document.getElementById("reducefigure");
    minus.onclick = (event) -> num--;
}

}

现在圆圈是自动添加的，如何制作，以便单击另一个图形并且已经添加了动画，并且自动推导出了2个图形。即点击1秒显示2个数字，
