We are maintaining our game engine forked from ‘Cocos2d-x’. Recently, official support is stopped, we want to change its base implementations to Unreal.
Does Unreal have pure APIs to build games without its editor? If we can’t build a game or a scene from scratch with pure APIs only, we can’t change ‘Cocos2d-x’ implementation to Unreal’s?
We know old version of Unreal Engine has a SDK named ‘UDK’, is it still there in Unreal Engine 4.x?
