(if player joins, a part becomes transparent)Can someone help with my playerAdded problem?

script.Parent.Touched:Connect(function(hit)
game.Workspace.LavaLetdown.BarrierLLD.Transparency = 1
game.Workspace.LavaLetdown.BarrierLLD.CanCollide = false
end)

game.Players.PlayerAdded:connect(function(player)
local stat = Instance.new("IntValue",  player) -- can just change this to whatever type of value you want
stat.Name = "variable"
stat.Value = 0
end)

I need help with combining this two or something so that: if the player joins, barrierlld becomes transparent and false cancollide

You just take away the Touched Event so whenever the player joins it automatically turns invisible

game.Players.PlayerAdded:Connect(function(player)
	local stat = Instance.new("IntValue",  player) -- can just change this to whatever type of 			value you want
	stat.Name = "variable"
	stat.Value = 0

	game.Workspace.LavaLetdown.BarrierLLD.Transparency = 1

	game.Workspace.LavaLetdown.BarrierLLD.CanCollide = false
end)

Or if this is what you want just put the Touched Event inside the PlayerAdded Event which isn't different than the code you have written, so I don't see how you would want this.

game.Players.PlayerAdded:Connect(function(player)
	local stat = Instance.new("IntValue",  player) -- can just change this to whatever type of 			value you want
	stat.Name = "variable"
	stat.Value = 0

	script.Parent.Touched:Connect(function(hit)
		game.Workspace.LavaLetdown.BarrierLLD.Transparency = .3

		game.Workspace.LavaLetdown.BarrierLLD.CanCollide = false
	end)
end)
