Hallo
Ich habe mir einen Nagelband script besorgt und bischen bearbeitet.Es kommt dauert ein error dann stürzt der Server ab.
Script:
nagelband = createObject(2892,-2047.4000244141,-102.69999694824,39.900001525879,0,0,90.25 )
x = -2047.4000244141
y = -102.69999694824
setElementData ( nagelband, "nagel", "nagel")
hammer1 = createColCircle(x,y-1,1)
hammer2 = createColCircle(x,y-2,1)
hammer3 = createColCircle(x,y-3,1)
hammer4 = createColCircle(x,y-4,1)
hammer5 = createColCircle(x,y-5,1)
hammer6 = createColCircle(x,y,1)
hammer7 = createColCircle(x,y+1,1)
hammer8 = createColCircle(x,y+2,1)
hammer9 = createColCircle(x,y+3,1)
hammer10 = createColCircle(x,y+4,1)
hammer11 = createColCircle(x,y+5,1)

function damage(hammer1,hammer2,hammer3,hammer4,hammer5,hammer6,hammer7,hammer8,hammer9,hammer10,hammer11)
 local players = getElementsByType("player")
	for i,player in ipairs(players) do


		if isElementWithinColShape(player,hammer1) or isElementWithinColShape(player,hammer2) or isElementWithinColShape(player,hammer3) or isElementWithinColShape(player,hammer4) or isElementWithinColShape(player,hammer5) or isElementWithinColShape(player,hammer6) then
			if isPedInVehicle(player) then
			vehicle = getPedOccupiedVehicle(player)
			setVehicleWheelStates(vehicle, 1, 1, 1, 1)
			end
		end
	end
end
addEventHandler( "onElementColShapeHit", getRootElement(), damage)

Errorcode:

178: Bad argument @ 'isElementWithinColShape'
