Making checkpoints and make them WORK

[Beatlebattle]

Isn't it possible to just make a save command at the checkpoint and when you die it loads the auto save? I don't know what AutoSave(); is used for but it would rather be much easier to make a save then resettiing everything in the whole map when respawning at the checkpoint.

I'm gonna explain what I'm trying to do;

You get into a room and theres a key you need to pickup. When you picked it up, enemies spawn in the map. You get killed by one of the monsters. You will respawn in front of the room again and need to pickup the key once again. So it's not like I want specific things to reset. I just want the game to auto save my position when infront of the room.
