I've been breaking my head for days. I really don't know how to make a door. When the player opens the door he can go into another room and if he comes back to the door he goes back to the previous room. I tried with a checkpoint, with portal and I don't find a way. Is it impossible? With checkpoint, my player goes to the next checkpoint without a problem. But when he goes to the next checkpoint he can't go back. I really don't know why. Why there is no variable or Id on a feature like checkpoint? I really need your help.
@HueTheDev , thanks a lot. Whoah, it works perfectly! I tried so complex methods, this one is so easy... Why I didn't think about it? ^^
