EntityAnno

Utility tools for generating Mindustry custom entity component classes.

Installation

Note that this only works with Java projects, not Kotlin or Scala or other similar JVM languages. The important bits are as following:

0. • Install JDK 17 or above.
   • Use Anuke's mod template. Not doing so will render you as "know what you're doing" and it's your responsibility to bend the guides as suited to your needs (see Entesting for an example without the template).
   • Assume / is your mod's root folder.
   • If mentioned files don't exist, create them.
1. Go to /settings.gradle and add these lines:

   pluginManagement{
       repositories{
           gradlePluginPortal()
           maven{url 'https://www.jitpack.io'}
       }
   }
   
   if(JavaVersion.current().ordinal() < JavaVersion.VERSION_17.ordinal()){
       throw new GradleException("JDK 17 is a required minimum version. Yours: ${System.getProperty('java.version')}")
   }

   This is done so that Gradle can find this plugin, and to enforce usage of Java 17+ for compiling.
2. Go to /gradle.properties and add these lines:

   mindustryVersion = v145
   arcVersion = v145
   entVersion = 1.1.0
   
   kapt.include.compile.classpath = false
   kotlin.stdlib.default.dependency = false

   • You can tweak mindustryVersion to any tag/commit you prefer (and have arcVersion exactly the same as said Mindustry version uses, done by looking at the archash property in Mindustry's gradle.properties).
   • entVersion should be left alone, and set to the latest release of this repository (not Mindustry! Exact fetched sources will be dealt with later).
   • The KAPT/Kotlin stuff at the bottom is used to decrease compile-time penalty and not use the entire Kotlin JVM standard libraries, because they're literally pointless in this context.
3. Go to /gradle.properties, and in the property org.gradle.jvmargs, replace --add-exports with --add-opens and remove --illegal-access=permit so it looks like below:

   org.gradle.jvmargs = \
   --add-opens=jdk.compiler/com.sun.tools.javac.api=ALL-UNNAMED \
   --add-opens=jdk.compiler/com.sun.tools.javac.code=ALL-UNNAMED \
   --add-opens=jdk.compiler/com.sun.tools.javac.model=ALL-UNNAMED \
   --add-opens=jdk.compiler/com.sun.tools.javac.processing=ALL-UNNAMED \
   --add-opens=jdk.compiler/com.sun.tools.javac.parser=ALL-UNNAMED \
   --add-opens=jdk.compiler/com.sun.tools.javac.util=ALL-UNNAMED \
   --add-opens=jdk.compiler/com.sun.tools.javac.tree=ALL-UNNAMED \
   --add-opens=jdk.compiler/com.sun.tools.javac.file=ALL-UNNAMED \
   --add-opens=jdk.compiler/com.sun.tools.javac.main=ALL-UNNAMED \
   --add-opens=jdk.compiler/com.sun.tools.javac.jvm=ALL-UNNAMED \
   --add-opens=jdk.compiler/com.sun.tools.javac.comp=ALL-UNNAMED \
   --add-opens=java.base/sun.reflect.annotation=ALL-UNNAMED

   This is done to grant necessary internal API accesses for the annotation processor.
4. Go to /build.gradle and replace this line:

   apply plugin: "java"

   With these:

   plugins{
       id 'java'
       id 'com.github.GlennFolker.EntityAnno' version "$entVersion"
   }

   This is the core part of the usage.
5. Go to /build.gradle and replace these lines:

   targetCompatibility = 8
   sourceCompatibility = JavaVersion.VERSION_16

   With these:

   sourceCompatibility = 17
   tasks.withType(JavaCompile).configureEach{
       sourceCompatibility = 17
       options.release = 8
   
       options.incremental = true
       options.encoding = 'UTF-8'
   }

   This is to allow compiling with Java 17 syntaxes while targeting Java 8 bytecodes.
6. Go to /build.gradle and replace these lines:

   ext{
       //the build number that this mod is made for
       mindustryVersion = 'v145'
       jabelVersion = "93fde537c7"
       sdkRoot = System.getenv("ANDROID_HOME") ?: System.getenv("ANDROID_SDK_ROOT")
   }
   
   //java 8 backwards compatibility flag
   allprojects{
       tasks.withType(JavaCompile){
           options.compilerArgs.addAll(['--release', '8'])
       }
   }

   With these:

   ext{
       sdkRoot = System.getenv("ANDROID_SDK_ROOT") ?: System.getenv("ANDROID_HOME")
   }

7. Go to /build.gradle and replace these lines:

   dependencies{
       compileOnly "com.github.Anuken.Arc:arc-core:$mindustryVersion"
       compileOnly "com.github.Anuken.Mindustry:core:$mindustryVersion"
   
       annotationProcessor "com.github.Anuken:jabel:$jabelVersion"
   }

   With these (without the comments, of course):

   dependencies{
       // i.
       compileOnly "com.github.Anuken.Arc:arc-core:$arcVersion"
       compileOnly "com.github.Anuken.Mindustry:core:$mindustryVersion"
   
       // ii.
       annotationProcessor "com.github.GlennFolker.EntityAnno:downgrader:$entVersion"
   
       // iii.
       compileOnly "com.github.GlennFolker.EntityAnno:entity:$entVersion"
       // iv.
       kapt "com.github.GlennFolker.EntityAnno:entity:$entVersion"
   }

   1. Adds Mindustry and Arc as a compile classpath.
   2. Lets you use Java 9+ syntaxes while still targeting Java 8 bytecode (which is necessary), mostly because Java is stupid.
   3. Adds the annotation processor classpath into your project, without bundling them into the final .jar.
   4. Registers the annotation processor to the compiler. Why KAPT? Because KAPT is fast and generally friendly to incremental compilation, especially if your project is decoupled into several modules (like Confictura).
8. Go to /build.gradle and remove these lines:

   //force arc version
   configurations.all{
       resolutionStrategy.eachDependency { details ->
           if(details.requested.group == 'com.github.Anuken.Arc'){
               details.useVersion "$mindustryVersion"
           }
       }
   }

9. Add this property block in /build.gradle wherever you like (as long as it's done in project evaluation, that is):

   entityAnno{
       modName = 'your-mod-name'
       mindustryVersion = project['mindustryVersion']
       revisionDir = file("$rootDir/revisions/")
       fetchPackage = 'yourmod.fetched'
       genSrcPackage = 'yourmod.entities.comp'
       genPackage = 'yourmod.gen.entities'
   }

   • modName is the internal mod name as specified in your /mod.json.
   • mindustryVersion is the Mindustry version that you use (project['mindustryVersion'] refers to the property in /gradle.properties, so make sure the property name matches!), so that the annotation processor fetches correct entity component source codes.
   • revisionDir is used for saves and netcodes history, don't worry about it. Just make sure not to .gitignore the folder.
   • fetchPackage, genSrcPackage, and genPackage are respectively the package names for storing downloaded vanilla sources, your entity component sources (that'll be excluded from the final .jar), and the resulting generated entity classes. Change yourmod to your mod's root package name.
10. Add the line EntityRegistry.register(); (from the genPackage) in your mod class' loadContent() method.
11. Refer to usage for more detailed entity annotation usages.
12. Compile and use the mod as the guide in the mod template says.
