  • 重现方式：重复调用loadBundle方法去加载同一个bundle

  • 之前哪个版本是正常的 ：

  • 手机型号 ：

  • 手机浏览器 ：

  • 编辑器操作系统 ：

  • 编辑器之前是否有其它报错 ：

  • 出现概率：

  • 额外线索：
    想实现的场景是游戏进来先预加载一些弹窗模块 等到用户主动拉起弹窗的时候可以更快的展示出来

这个是游戏刚进来时的预加载弹窗代码

这个是用户主动拉起弹窗时的代码

我也遇到了，这个问题解决了么？

#3

@jare 确实是bug 必现

#4

我也碰到了。感谢提示是重复调用loadBundle导致的问题。
我改成存在相同调用，就使用同一个回调，果然没问题了。

我也遇到了，必现bug；引擎版本2.4.1

#6

能给个demo？

#8

2.4.2也有这个bug，用tbwind的方法顺利解决，demo大概这样

for(let i=0; i<10; i++)
{
cc.assetManager.loadBundle(bundleName, (err:Error, bundle: cc.AssetManager.Bundle)=>{

            });

}
在web-mobile release下回出现bug，在CC_PREVIEW不会出现。

@tbwind 大神也，比引擎组不知高到哪里去了。
