Script only runs while a player is standing on a specific brick

[k6den (kaden)]

Hi! I’m pretty sure what I am trying to do is supposed to be simple, however I cannot figure out how to script it. What I’m trying to do is have a simple brick turn visible when it detects that a player is standing on it. As soon as the brick doesn’t detect a player standing on it, the brick will turn invisible. How would I be able to achieve this?

You would use .Touched and .TouchEnded to detect when the brick is touched and when it’s not. In those functions, you can set Transparency to 1 and 0 respectively.

In this case, you would want to connect to Humanoid.Touched to avoid too many connections.

--StarterPlayerScripts
local Players = game:GetService("Players")
local RunService = game:GetService("RunService")

local Player = Players.LocalPlayer
local RenderStepped = RunService.RenderStepped

local rcParams = RaycastParams.new()
rcParams.FilterType = Enum.RaycastFilterType.Include

local down = -Vector3.yAxis
local invisibleTransparency = 0.6 --change to 1 to make it fully invisible

function onCharacterAdded(character)
	if not character then
		return
	end
	local inProcess = false
	local Humanoid = character:WaitForChild("Humanoid")
	local Root = Humanoid.RootPart
	Humanoid.Touched:Connect(function(hit)
		if inProcess then
			return
		end
		--If the hit part exists and is named 'transparentBrick', initialize the raycast params and make it visible.
		if hit and hit.Name == "transparentBrick" then
			inProcess = true
			rcParams.FilterDescendantsInstances = {hit}
			hit.Transparency = 0
			
			--[[
			Every frame, check if the raycast result is returned. If not, the part is
			not on the humanoid and we can end the loop and make it invisible.
			]]
			while true do
				local result = workspace:Raycast(Root.Position, down * 3, rcParams)
				if not result then
					break
				end
				RenderStepped:Wait()
			end
			hit.Transparency = invisibleTransparency
			inProcess = false
		end
	end)
end

onCharacterAdded(Player.Character)
Player.CharacterAdded:Connect(onCharacterAdded)

In the code above, the part that the humanoid steps on is checked via raycasting downwards and as soon as the humanoid exits the position, the part is made invisible.
