Platinum Arts Sandbox - Free 3D Game Maker Forum

I would like to make RPG with some co-op(maybe). I have some ideas, it will be something ala LOST game, but I would like to know some things first. My questions is how to:
- make menu(start, options, high scores etc)
- create character option
- make invisible wall...
...becose player can get out of map

Its not going to be multiplayer. But...

I was searching in FAQ and Wiki but I didnt found answer to mu question.

invisible walls are clip and no clip, character creation isn't available at the moment. The menu will require some coding FYI =]

Ok thx

Its possible to made character creation with code?
