I just saw that you decided to integrate a real scripting language after all, great news!
Whatever language you chose here, will likely become the core of modding in the future. Especially for more complex mods that would be a chore to create in blueprints.
So it’s very important that this does not require any pre-compile steps in the editor, and the game (in shipping configuration) is able to execute and update custom scripts at runtime.
I’m sure you have already planned it like this, just want to confirm!
