我正在为FreeCodeCamp的前端证书做最后的项目。我把它变成了一个格斗游戏,按钮序列开始移动。问题是动画真的很麻烦。以下是详细信息:
--- ---背景 - codepen链接和代码位于底部 - 当我在本地编码时,一切都运行良好,玩家的动作是使用基于jquery的动画完成的。 (我使用了setTimeout(),animation(),css()和attr()来移动虚拟形象并切换图片以显示移动
- 问题--- - 我把代码放在codepen上,所以我需要托管精灵图像来使用它们(我使用了dropbox)。此更改导致动画无法正常工作。一些图像和声音加载缓慢或根本不加载。如果你去codepen并尝试底部的按钮,你会很快看到我的意思。
---我尝试了什么--- - 我认为这可能是一个问题,应用程序花了太长时间来加载资产并缓存它们。 (因为在我重复之后,一些动画变得更加流畅)所以我在顶部附近添加了一个函数来加载照片的开头' imageInit()'。但问题仍然存在。
任何人都可以帮我弄清楚是什么让我的jquery动画变得如此不稳定和不一致?我可能使用错误的技术吗?如果您需要更多信息,请与我们联系。代码如下:
谢谢!
