How to make it so you turn unvisible when your press a text button?

So i have a game were your in a lobby and you can only see yourself. I made it so your not invisible but all the other players are. So to a players eye they only see there own character. But i have a text button "Play" so when they press that button they are supposed to fight each other.. the thing is they are invisible accept for them self's how to i make it when they press that text button it undos the invisible script.

while wait(1) do
local hide = true

local orignalTransparency = {}

local function checkPart(part)
	for a,b in pairs(part:GetChildren()) do 
		checkPart(b) 
	end
	if part:IsA("BasePart") or part:IsA("Decal") then
		if hide then 
			if not orignalTransparency[part] then
				orignalTransparency[part] = part.Transparency
			end
			part.Transparency = 1
			
		else 
			if orignalTransparency[part] then 
				part.Transparency = orignalTransparency[part] 
				orignalTransparency[part] = nil 
			end
		end
	end
end

local players = game:GetService("Players")
local localPlayer = players.LocalPlayer

game:GetService("RunService").RenderStepped:Connect(function()
	for i,v in pairs(players:GetPlayers()) do
		if v ~= localPlayer then
			local char = v.Character
			if char then
				checkPart(char)
				char:WaitForChild("Head").OverHead.Enabled = false
			end
		end
	end

	for part,trans in pairs(orignalTransparency) do
		if not part then
			orignalTransparency[part] = nil
		elseif not part.Parent then
			orignalTransparency[part] = nil
		end
	end
end)

while true do
	hide = true
	wait(2.5)
end
end

Try disabling the script. Just say: TheScriptYouWantToStop.Disabled = true

BaseScript.Disabled
