We are 4th year students trying to build an android app using unity, but we need to embed or add a language compiler or interpreter so users can do live coding while they use the android application we made? is this possible in unity?
Yeah I would also recommend a scripting language, preferably Lua. You will find a solution on the store as well as github and even taking a general C# wrapper for Lua and make it work (if at all necessary) within Unity is within reach.
Seconding the suggestions on Lua or MiniScript. Lua may be familiar to users who already have experience modding games. If you don’t think there’s an overlap between modders and your app users, MiniScript is somewhat simpler to learn, easy to get working in Unity, and the author ( @JoeStrout ) is here on the forums.
