Building the plugin

Easy installation

Unreal.js is now on the Unreal Engine MarketPlace. If you have installed Unreal Engine from Epic Games Launcher, you can grab Unreal.js from the MarketPlace.

Build process

• Make sure you have installed the UnrealEngine 4.13.? canonical build.
• Create a UE4 C++ project and close the editor after the project creation is finished
• Clone the content of Unreal.js-core into the {ProjectRoot}\Plugins\UnrealJS directory of the UE4 project directory

cd {ProjectRoot}
git clone https://github.com/ncsoft/Unreal.js-core Plugins/UnrealJS
cd Plugins/UnrealJS

• For Windows,
  • Run install-v8-libs.bat in Git CMD
  • Or run install-v8-libs.sh in Git bash
• For other platforms,
  • Run install-v8-libs.sh
• Now open the C++ .uproject again in the UE editor
• Once the UE Editor opens the project it should ask if you want to rebuild the plugin modules, click Yes to start the C++ build
• The compilation of the Unreal.js plugin should go through and you end up with a compiled version of the plugin in the {ProjectRoot}\Plugins\UnrealJS directory
• To verify that the C++ binaries of the plugin have been built check that the DLLs for the plugin have been created in {ProjectRoot}\Plugins\UnrealJS\Binaries\Win64
• In the UE Editor you can check that the plugin was successfully loaded in Edit > Plugins > Project > Programming > Unreal.js - Javascript Runtime
• You can then start using the plugin in the project or copy the built plugin folder to a different UE project (Blueprint or C++) and use it there
