Java libgdx加载资源，纹理打包器
很抱歉打扰您，我知道已经有人问过了，但我无法解决它。我已经开始与libgdx合作，并决定将一本书作为教程——《学习LigbGDX游戏开发》。在第四章之前一切都很顺利，我无法将资产加载到canyonbunny.pack。我不知道发生了什么事。在../CanyonBunny android/assets/images中创建了两个文件-一个是png，另一个是atlas。如果你能帮我一把，我将非常欢迎Java libgdx加载资源，纹理打包器,java,libgdx,texturepacker,Java,Libgdx,Texturepacker,很抱歉打扰您，我知道已经有人问过了，但我无法解决它。我已经开始与libgdx合作，并决定将一本书作为教程——《学习LigbGDX游戏开发》。在第四章之前一切都很顺利，我无法将资产加载到canyonbunny.pack。我不知道发生了什么事。在../CanyonBunny android/assets/images中创建了两个文件-一个是png，另一个是atlas。如果你能帮我一把，我将非常欢迎 DesktopLauncher.java package com.packtub.libgdx.ca

TexturePacker自动放置settings.atlasExtension（“.atlas”）定义的扩展名
更改此设置或将Constants.TEXTURE_ATLAS_OBJECTS变量的值更改为“canyonbunny.pack.ATLAS”。将设置atlasExtension设置为“”
