[SCRIPT] Somekind of CheckPoints needed

[Obliviator27]

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.
