--This is the principal Door script--


local P1 = script.Parent.Puerta1

local P2 = script.Parent.Puerta2

local Det1 = script.Parent.Det1

local Det2 = script.Parent.Det2

 

P1.Transparency=0

P2.Transparency=1

P2.CanCollide=false

Det2.ClickDetector.MaxActivationDistance=0

 

Det1.ClickDetector.MouseClick:connect(function()

P1.Transparency=1

P1.CanCollide=false

P2.Transparency=0

P2.CanCollide=true

Det2.ClickDetector.MaxActivationDistance=32

Det1.ClickDetector.MaxActivationDistance=0

end)
