Building the plugin

• Make sure you have installed the UnrealEngine 4.12.? 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
• (or download the ready to build Zip file and extract it in the {ProjectRoot}\Plugins\UnrealJS directory)
• Download the V8 prebuilt binaries or build them yourself and put them in the {ProjectRoot}\Plugins\UnrealJS\ThirdParty\v8\lib\Win64\Release directory
• 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
