Roblox Studio: Scripting #1

I am teaching you how to do scripting.
Script Code:
local door = script.Parent

function open()
-- This function will open the door.
door.CanCollide = false -- Make players able to walk through the door.

for transparency = 0, 1, .1 do
door.Transparency = transparency
wait(.1)
end
end

function close()
-- This function will close the door.
for transparency = 1, 0, -.1 do
door.Transparency = transparency
wait(.1)
end

door.CanCollide = true -- Make players unable to walk through the door.
end

-- This function returns the player a certain part belongs to.
function get_player(part)
--iterate over each player
for _, player in ipairs(game.Players:GetPlayers()) do
--if the part is within the player's character
if part:IsDescendantOf(player.Character) then
--return the player
return player
end
end
end


door.Touched:connect(function(part)
-- If it isn't a character that touched the door, then we ignore it.
local player = get_player(part)
if not player then return end

local allow = (
player.Name == "Player Name" or
player.Name == "Player Name" or --Put your name here.
player.Name == "Player Name" or
player.Name == "Player Name" or
player:IsInGroup(61277) and player:IsFriendsWith(game.CreatorId) or -- This demonstrates how you can use 'and' to combine two restrictions.
game:GetService('BadgeService'):UserHasBadge(player.userId, 1032571) or
game.CreatorId == player.userId
)
if allow then
open()
delay(4, close)
end
end)
