This is a simple Godot 4 project with the additional Gradle parts necessary to build and run scripts written in Kotlin, Java, or Scala. It will simply display text on screen written by unique Kotlin, Java, and Scala source files.
To use it, simply download the Godot Kotlin/JVM custom engine here: https://github.com/utopia-rise/godot-kotlin-jvm/releases
Then build the project, like you would with any other Kotlin project to generate a .jar. It will be picked up automatically by the engine. Make sure that the engine version defined the gradle.build file matches the one you downloaded.
