当使用GWT为HTML编译时，LibGDX“.DT_Store”文件未找到错误消息

Question

在基于LibGDX的项目中，编译HTML项目时（使用GWT），您的资产文件夹中隐藏的'.DT_Store'文件将不会部署但仍然会被引用。这会导致：

“.DT_Store文件” 找不到

当你打开页面。

Answer 1

您需要过滤掉您不希望包含在您的部署中的文件。

此解决方案可以应用于任何其他您要排除的文件。

在.gwt.xml文件

，添加以下标签：

<set-configuration-property name="gdx.assetfilterclass" value="com.my.Package.DefaultAssetFilter" /> 
<set-configuration-property name="gdx.assetpath" value="../android/assets" /> 

在你的HTML项目

，添加一个类：

package com.my.Package; 

import com.badlogic.gdx.backends.gwt.preloader.AssetFilter;
