someone know a delay script?

To be honest it depends on the sort of situation you're making a delay for, and you haven't said.

If it's a quest:

Int bQuickeningBegin GameMode	If (bQuickening != Criterion)		Set bQuickening to (bQuickening == 0)		If bQuickening			SetQuestDelay ThisQUST 0.01 ; Every frame		Else			SetQuestDelay ThisQUST 0 ; Five second intervals (Default)		EndIf		Return	ElseIf bQuickening		;Fast code	Else		;Slow code	EndIfEnd

Or do you mean you just want it to not run until... something happens?

i want a delay before resurrect an npc

The quest method is probably what you want. I'd look at the character generation quest (VCG01), it has a delay between most of its stages (to time the doc's lines, that are spoken outside of dialog mode, etc)
