Blinking for NPC not working

Help and Feedback Scripting Support

#1

Hey, I’ve been trying to add blinking to my NPC. But it just doesn’t work, there used to be an error saying attempt to index nil with “Closed” but since I added the “if face then” it’s gone. But it still doesn’t work, could anyone check it out and tell me what is wrong?

local faceTable = {}
	
	for i,v in pairs(game.ReplicatedStorage:WaitForChild("Faces"):GetChildren()) do
		table.insert(faceTable,v)
	end
	
	local face = faceTable[math.random(1,#hairTable)]
	local mobFace = mob:WaitForChild("Head"):WaitForChild("Decal")
		
	if mobFace and face then
		coroutine.wrap(function()

			while true do
				mobFace.Texture = face:WaitForChild("Closed").Texture
				wait(0.5)
				mobFace.Texture = face:WaitForChild("Open").Texture
			end
		end)()
	end

As I can see you’re trying to find all faces inside of Replicated Storage, but isnt that easier to just find them with WaitForChild?

Thats blinking script that i using in my game:

local Face = script.Parent

local Closed = Face:GetAttribute("Closed")
local Open = Face:GetAttribute("Open")

local Wtick = Face:GetAttribute("Tick")

if Face then
	while true do
		local randomV = math.random(15,50) / 10
		wait(randomV)
		Face.Texture = Closed
		wait(Wtick)
		Face.Texture = Open
	end
end

I added 3 Attributes: Closed eyes texture, Open eyes texture and delay between opening and closing eyes

Thats seems like easiest way to do it in my opinion

All that script i put in Face decal

'attempt to index nil with “Closed”' means that the face doesn’t exist

My first questions here then are:

  • Are there faces in the face folder?

  • If the answer to that is yes, does the number of items in the hair table match the number of items in the face table

  • If the answer to that is no, that might be your issue

  • third, add a wait(0.05) between the open texture and the end of the while true do loop, as the textures might be changing so fast that it LOOKS like nothing is happening
