How to make building games?

so i want to make a builder type game, but i don’t fully understand how they work. i’m talking about games like Crossout where you build the entire model from scratch. how does that work, because doesn’t the model have to be rigged and things like that to be functional? how would i make a game where the player can create their own things?

@Lt.Matthew You’re probably not getting an answer to this because it’s way too vague :wink:

You basically need to make a game that works a little bit like the editor.

Start simple, just have a cube, write some code so the player can pick it up and put it down again. Then work from there…( this might use ‘Attach component’ or something like that )
