如何在两个动画 Canvas 元素之间进行通信？

Question

我想在两个动画 canvas 元素之间进行交流。

我用 Adobe Animate CC 制作了两个 html5 canvas js 动画。我已将这两个元素放在一个 html 页面中。我可以从这些动画中成功调用函数 - 警报在下面的代码中成功触发。

我想从一个动画中调用函数来控制另一个动画。我需要帮助了解如何正确 call/name/address 动画。到目前为止，我没有收到 canvas_ship.gotoAndPlay(12); 和 canvas_car.gotoAndPlay(7); 的回复，我已经花了几个小时尝试不同的参考资料。我不是一个大程序员，但我确信这是一件简单的事情。感谢您的帮助！

我得到了帮助，现在分享答案。不客气。找个时间请我吃顿饭吧。

在 Adobe Animate 中，您需要将库命名空间（我认为是在“高级”选项卡的“发布”设置中）更改为 lib_jerry 或您想出的任何自定义名称...只要它不同于其他动画。然后只需按照此代码中的设置进行操作。您可以从 Animate 动画中调用函数。

<script src="jerry.js"></script>
<script>

var canvas, stage, tomtom, jerjer;
function init() {

    var exportRoot;

    //Tommy
    canvas = document.getElementById("canvas_tommy");

    tomtom = new lib_tommy.tommy();
    stage = new createjs.Stage(canvas);
    stage.addChild(tomtom);
    stage.update();

    createjs.Ticker.setFPS(lib_tommy.properties.fps);
    createjs.Ticker.addEventListener("tick", stage);


    //Jerry
    canvas = document.getElementById("canvas_jerry");

    jerjer = new lib_jerry.jerry();

    stage = new createjs.Stage(canvas);
    stage.addChild(jerjer);
    stage.update();

    createjs.Ticker.setFPS(lib_jerry.properties.fps);
    createjs.Ticker.addEventListener("tick", stage);

}

function button_from_tommy_was_clicked(){   
    tomtom.gotoAndPlay(5);
}

function button_from_jerry_was_clicked(){   
    jerjer.gotoAndPlay(5);
}
