[SCRIPT] Somekind of CheckPoints needed

[Ermu]

EDIT: A bit offtopic question, but how do block ie. unlitted candle from being litted by the player?

You can either
A) Edit it in the model editor so it's just a staticprop
or
B) Clever use of script areas. I/e, putting a box around the entity which, when interacted with displays a message of "This candle cannot be lit." I'd have to look into it to be completely sure that it would work, but it should work just fine for you.

Got that figured out right before reading this, now i only got the problem with the lever.
Thanks anyways!
