How can I change a property of a part for the localplayer?

I have made a code when you touch a block the properties of an other part changes. It works, but everyone sees it. I want that the property only changes for the local player. Can someone help me? these are the codes I have made 2 local scripts in the startergui.

local Workspace = game.Workspace

local mainpart = Workspace.Touchablewall1
local secondarypart = Workspace.Part28
local thirdpart = Workspace.Part29
local secondmainpart = Workspace.Touchablewall2
local Players = game:GetService("Players")

local db = true
mainpart.Touched:connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") ~= nil then
		if db == true then
			db = false
			secondarypart.Transparency = 1
			secondarypart.CanCollide = false
			mainpart.Transparency = 0
			thirdpart.CanCollide = true
			thirdpart.Transparency = 0
			secondmainpart.Transparency = 1
			local player = game.Players:GetPlayerFromCharacter(hit.Parent)
			player.leaderstats.Coins.Value = player.leaderstats.Coins.Value + 1
			mainpart.Transparency = 0
			secondarypart.Transparency = 1
			secondarypart.CanCollide = false
			thirdpart.CanCollide = true	
			thirdpart.Transparency = 0
			secondmainpart.Transparency = 1
			wait(0.1)
			db = true
			mainpart.Transparency = 1
			secondarypart.Transparency = 0
			secondarypart.CanCollide = true
			thirdpart.CanCollide = false
			thirdpart.Transparency = 1
			secondmainpart.Transparency = 0
		end
	end	
end)

-----other script

local Workspace = game.Workspace

local mainpart = Workspace.Touchablewall2
local secondarypart = Workspace.Part29
local thirdpart = Workspace.Part28
local secondmainpart = Workspace.Touchablewall1

local db = true
mainpart.Touched:connect(function(hit)
	if hit.Parent:FindFirstChild("Humanoid") ~= nil then
		if db == true then
			db = false
			secondarypart.Transparency = 1
			secondarypart.CanCollide = false
			mainpart.Transparency = 0
			thirdpart.CanCollide = true
			thirdpart.Transparency = 0
			secondmainpart.Transparency = 1
			local player = game.Players:GetPlayerFromCharacter(hit.Parent)
			player.leaderstats.Coins.Value = player.leaderstats.Coins.Value + 1
			mainpart.Transparency = 0
			secondarypart.Transparency = 1
			secondarypart.CanCollide = false
			thirdpart.CanCollide = true
			thirdpart.Transparency = 0	
			secondmainpart.Transparency = 1
			wait(0.1)
			db = true
			mainpart.Transparency = 1
			secondarypart.Transparency = 0
			secondarypart.CanCollide = true
			thirdpart.CanCollide = false
			thirdpart.Transparency = 1
			secondmainpart.Transparency = 0
		end
	end	
end)
