How do I make a touch brick that make npc appear and disappear after awhile?

I tried many scripts, I searched on YouTube too. I couldn't find a script that makes a npc appear for a while then disappears. Is there anyway I can get help?

Put the NPC in storage and then call for it to be :cloned() to workspace by a script which detects when a block it touched :) then wait for a while the :destroy() it :)

If you wanted to make an NPC, for example, appear for maybe 5 seconds after a brick is touched we could do the following:

-- By using the RBXScriptSignal, or event, Touched, the script will detect when a block is touched

game.Workspace.OurBrick.Touched:Connect(function	

end)

Now, let's set up a few functions when the event fires

game.Workspace.OurBrick.Touched:Connect(function

	-- This function makes the NPC appear (or change position)

	local function npcAppear()
		local npc = game.Workspace.NPC
		local appearPart = game.Workspace.appearPart -- This is the block that the NPC will teleport to		

		npc:SetPrimaryPartCFrame(appearPart.CFrame) -- This will make the NPC teleport to the part

	end


	-- This function will make the NPC disappear

	local function npcDisappear()
	
		local npc = game.Workspace.NPC
		local disappearPart = game.Workspace.disappearPart
		
		npc:SetPrimaryPartCFrame(disappearPart.CFrame) -- The part it positions to should be in a place the player cannot see
	

	end

end)

So now that we have set up our functions to make the NPC appear/disappear, let's use them

game.Workspace.OurBrick.Touched:Connect(function


	local function npcAppear()
		local npc = game.Workspace.NPC
		local appearPart = game.Workspace.appearPart	

		npc:SetPrimaryPartCFrame(appearPart.CFrame)

	end


	local function npcDisappear()
	
		local npc = game.Workspace.NPC
		local disappearPart = game.Workspace.disappearPart
		
		npc:SetPrimaryPartCFrame(disappearPart.CFrame)
	
		-- Now we will use our functions and make the NPC appear and then disappear after 5 seconds		

		npcAppear()
		wait(5)
		npcDisappear()

	end

end)

So, to recap what we just talked about: We set up a connection when the .Touched event is fired. Inside the connection, we set up two functions, one to make the NPC appear and one to make it disappear. Inside these functions we used :SetPrimaryPartCFrame so that it would teleport the entire NPC and not just one part. Once we set up the functions, we used them to make the NPC appear for 5 seconds then disappear. I hope this helped you!
