We are developing a game in Unity. That game contains multiple mini-games. Those games are developed in Cocos2d-x. So the requirement is to combine the Cocos2d-x mini games on top of Unity game. I couldn’t get any clue how to do that. So any suggestion or guidance will be greatly appreciated.
If I’m understanding you correctly what you are asking is fundamentally impossible. If you want to house multiple mini games coded in a separate game engine than Unity you need to use Visual Studio or put them on a website.
