The easiest way is finding it on the Unreal Marketplace: 22 | https://www.unrealengine.com/marketplace/en-US/product/unrealjs 23 | 24 | If you can't find it in the Unreal Marketplace, you can install it manually following this instructions: 25 | https://github.com/ncsoft/Unreal.js/ 26 | 27 | - Clone or download this repository. 28 | 29 | Optionally change to a branch matching your engine version: 30 | 31 | [master](https://github.com/hiperbou/kotlin-unreal) branch will always be updated with the latest Unreal Engine version 32 | 33 | **Unreal Engine 5** 34 | 35 | [UE5.0.1](https://github.com/hiperbou/kotlin-unreal/tree/UE5.0.1-Kotlin1.4.31) 36 | 37 | **Unreal Engine 4** 38 | 39 | [UE4.27.2](https://github.com/hiperbou/kotlin-unreal/tree/UE4.27.2-Kotlin1.4.31), 40 | [UE4.27.1](https://github.com/hiperbou/kotlin-unreal/tree/UE4.27.1-Kotlin1.4.31), 41 | [UE4.26.1](https://github.com/hiperbou/kotlin-unreal/tree/UE4.26.1-Kotlin1.4.31) 42 | 43 | - You should be able to right click the file "KotlinUnreal.uproject" and select "Launch Game" 44 | - You might be asked to recompile or update the project to your engine version and after that you should be seeing the First Person Game example. 45 | 46 | ## Check out the map examples 47 | Open the project with the Unreal Editor and open and play the maps located on the Maps directory inside the Content folder. 48 | Some of them might look empty at first, but the Kotlin magic will fill them with surprises when you get into the Play mode. 49 | 50 | ## WIKI 51 | Check out the wiki for details, tutorials and guides: 52 | 53 | https://github.com/hiperbou/kotlin-unreal/wiki 54 | 55 | ## VIDEOS 56 | Playlist on Youtube 57 | 58 | https://youtube.com/playlist?list=PLJm5YzQnui1RfCue2NJtEKDSAJf-Kh0WG 59 | 60 |
