带有 gradle 的 LibGDX 的 TexturePacker

LibGDX#39;s TexturePacker with gradle(带有 gradle 的 LibGDX 的 TexturePacker)

问题描述

我正在尝试创建一个根据说明运行 TexturePacker 的 gradle 任务 这里.(请注意，我使用的是 Android Studio 及其目录结构，而不是 Eclipse.)我首先将以下内容添加到 Android Studio 项目的 build.gradle:

I am attempting to create a gradle task which runs TexturePacker according to the instructions here. (Note that I am using Android Studio and its directory structure rather than Eclipse.) I first added the following to the Android Studio project's build.gradle:

import com.badlogic.gdx.tools.texturepacker.TexturePacker
task texturePacker << {
  if (project.ext.has('texturePacker')) {
    logger.info "Calling TexturePacker: "+texturePacker
    TexturePacker.process(texturePacker[0], texturePacker[1], texturePacker[2])
  }
}

这给出了错误

无法解析 com.badlogic.gdx.tools.texturepacker.TexturePacker 类

unable to resolve class com.badlogic.gdx.tools.texturepacker.TexturePacker

将 texturePacker 任务移动到桌面项目中的 build.gradle 会产生相同的错误.根据 http://www.reddit.com/r/libgdx/comments/2fx3vf/could_not_find_or_load_main_class_texturepacker2/，我还需要在根build.gradle下添加compile "com.badlogicgames.gdx:gdx-tools:$gdxVersion"桌面项目的依赖项.当我这样做时，我仍然得到同样的错误.

Moving the texturePacker task to build.gradle in the desktop project produces the same error. According to http://www.reddit.com/r/libgdx/comments/2fx3vf/could_not_find_or_load_main_class_texturepacker2/, I also need to add compile "com.badlogicgames.gdx:gdx-tools:$gdxVersion" to the root build.gradle under the desktop project's dependencies. When I do so, I still get the same error.

所以我有几个问题:

1. texturePacker 任务的正确位置在哪里?我应该把它放在哪个 build.gradle 中?

1. Where is the correct place for the texturePacker task? Which build.gradle do I put this in?

如何解决依赖问题和unable to resolve class...错误?

How do I solve the dependency issue and the unable to resolve class... error?

使用 gradle 运行时如何指定输入输出目录和 atlas 文件?(假设前两个问题已经解决.)

How do I specify the input and output directories and the atlas file when running this with gradle? (Assuming the first two questions are solved.)

推荐答案

我通过将 gdx-tools 添加到我的 buildscript 依赖项中使其工作:

I got it working by adding gdx-tools to my buildscript dependencies:

buildscript{
    dependencies {
       ...
       classpath 'com.badlogicgames.gdx:gdx-tools:1.5.4'
    }
}

通过这样做，我桌面的 build.gradle 能够导入纹理打包器类:

by doing this, my desktop's build.gradle was able to import the texture packer class:

import com.badlogic.gdx.tools.texturepacker.TexturePacker
task texturePacker << {
    if (project.ext.has('texturePacker')) {
        logger.info "Calling TexturePacker: "+ texturePacker
        TexturePacker.process(texturePacker[0], texturePacker[1], texturePacker[2])
    }
}

请注意，您的桌面项目的 ext 需要定义 texturePacker:

please note that your desktop project's ext will need to have texturePacker defined:

project.ext {
    mainClassName = "your.game.package.DesktopLauncher"
    assetsDir = new File("../android/assets");
    texturePacker = ["../images/sprites", "../android/assets", "sprites"]
}
