godot-kotlin

Introduction

Disclaimer - I probably do not have the technical expertise to actually make this work. If you happened upon this repo by searching or just browsing the org, don't expect much here :)

I have come across one (maybe two) others from Google searching who have posted about supporting Kotlin in Godot Engine. I'm probably wrong, but the little I have experimented and understand so far, the steps may be to use the cinterop to generate c bindings, and then perhaps a ton of work to expose Kotlin classes to interface with the interop functions.

Setup

1. Install Gradle
2. Clone godot-kotlin
3. Validate that the godot_headers submodule was pulled down, otherwise init
4. Install Kotlin plugin

Clone godot-kotlin

git clone git@github.com:godot-addons/godot-kotlin.git
git submodule init

Run Gradle

./gradlew clean build

Install the godotapi.klib

Run the command below, then open the project in CLion and it should pick things up.

klib install build/konan/libs/macos_x64/godotapi.klib

Kotlin Plugin

https://plugins.jetbrains.com/plugin/10454-kotlin-native-for-clion

Structure

• src/main/c_interop/godotapi.def is the Kotlin Native interop definition file which tells konan (kotlin native compiler) to include the c (*.h) header files from godot_headers
