Createjs - Tweenjs不适用于Bitmap

[英]Createjs - Tweenjs doesn't work with Bitmap

I have an example, i want to create animation with easel.js Bitmap but it seems not working. 我有一个例子,我想用easel.js Bitmap创建动画,但它似乎无法正常工作。 In this project, i use preload.js to load image; 在这个项目中,我使用preload.js来加载图像; crop card in cards picture; 卡片中的裁剪卡; create Bitmap object and try to animate this bitmap by using tween.js Anyone can help me. 创建Bitmap对象并尝试使用tween.js为此位图设置动画。任何人都可以帮助我。 Thank you! 谢谢!

This works just fine - except you skipped the "duration" parameter on the Tween.to call (and instead specified the ease, which is the 3rd parameter). 这很好 - 除了你跳过Tween.to调用上的“duration”参数(而是指定了ease,这是第3个参数)。 This makes it a 0-duration tween, which ends up off-stage (so you never see it). 这使得它成为一个0持续时间的补间,最终在场外(所以你永远不会看到它)。

Try this instead: 试试这个:

createjs.Tween.get(card).to({ x: 600, y: 1000 }, 1000, createjs.Ease.linear);
