I want t o make an RPG where along with giving you weapons your class morphs you and you continue respawning the same.
This is a rather complex question, and you require knowledge about all sorts of things. I'd recommend starting out with a basic class changer, and after that looking at morphs and incorporating their scripts into your own. This would be the easiest way to go about doing this, however if you made one from scratch it could be time consuming and advanced.
