Door continues to open even if player is not near?

You can use the Magnitude like me and make your Door work.

Today I created something similar to this but did otherwise.

I created two doors, one open and one closed, used magnitude for when I get the block the Closed Door model Stay invisible and Opened Door stay Visible, the version and more simplificated that his and which does not need a lot of work and moreover you you can leave her with many details.

The Script:

IntPart = script.Parent.Interact
Children = script.Parent.Parent.Door:GetChildren()
Children2 = script.Parent.Parent.OpenedDoor:GetChildren()

while wait() do
    for i,v in pairs(game.Players:GetChildren()) do
        if (v.Character.Torso.Position - IntPart.Position).magnitude <= 10 then
            v.PlayerGui.IntGuis[IntPart.Type.Value].Visible = true
            script.Key.Disabled = false

            for i = 1,#Children do
                if Children[i].ClassName == "Part" then
                    Children[i].Transparency = 1
                end
            end
            for i = 1,#Children2 do
                if Children2[i].ClassName == "Part" or Children2[i].ClassName == "UnionOperation" then
                    Children2[i].Transparency = 0
                end
            end
        else
            v.PlayerGui.IntGuis[IntPart.Type.Value].Visible = false
            script.Key.Disabled = true

            for i = 1,#Children do
                if Children[i].ClassName == "Part" then
                    Children[i].Transparency = 0
                end
            end
            for i = 1,#Children2 do
                if Children2[i].ClassName == "Part" or Children2[i].ClassName == "UnionOperation" then
                    Children2[i].Transparency = 1
                end
            end
        end
    end
end

This is your script, see if it works

local sp = script.Parent
local trigger = sp.trigger
local left = sp.left
local right = sp.right
local openOrClosed = sp.openOrClosed

local leftPosClosedX = 4.28
local leftPosOpenX = 10.28
local rightPosClosedX = -1.26
local rightPosOpenX = -7.26

while wait() do
    for i,v in pairs(game.Players:GetChildren()) do
        if (v.Character.Torso.Position - trigger.Position).magnitude <= 10 then
            if right.Position.X ~= rightPosClosedX and left.Position.X ~= leftPosClosedX then
                repeat
                        left.Position = Vector3.new(left.Position.X - 0.1, left.Position.Y, left.Position.Z)    
                        right.Position = Vector3.new(right.Position.X + 0.1, right.Position.Y, right.Position.Z)
                   wait(0.1)
                until
                right.Position.X == rightPosClosedX and left.Position.X == leftPosClosedX
            end
        else
            if right.Position.X ~= rightPosOpenX and left.Position.X ~= leftPosOpenX then
                repeat
                    left.Position = Vector3.new(left.Positon.X + 0.1, left.Position.Y, left.Positon.Z)
                    right.Position = Vector3.new(right.Position.X - 0.1, right.Position.Y, right.Position.Z)
                    wait(0.1)
                until
                right.Position.X == rightPosOpenX and left.Position.X == leftPosOpenX
            end
        end
    end
end

If it dont worked let me take a little longer to fix.
