"make me a keycard system for a hotel, provide me with instructions"

To create a keycard system for a hotel, you will need to follow these steps:

1. Create the keycard model.
2. Create a script for the keycard that assigns it to a specific room and player.
3. Create a script for the hotel room door that checks if the player has the correct keycard.
4. Create a system for distributing keycards to players.

Here's a basic implementation of each step:

Step 1: Create the keycard model
- In Roblox Studio, create a new part and name it "Keycard".
- Customize the appearance of the keycard as desired (color, size, etc.).

Step 2: Create a script for the keycard
- Insert a new script inside the keycard model and add the following code:

```lua
local keycard = script.Parent
keycard.RoomNumber = 1 -- Change this to the room number you want this keycard to unlock
```

Step 3: Create a script for the hotel room door
- Insert a new script inside the hotel room door model and add the following code:

```lua
local door = script.Parent
door.RoomNumber = 1 -- Change this to the room number this door belongs to
local unlocked = false

local function checkKeycard(player)
    for _, item in pairs(player.Backpack:GetChildren()) do
        if item.Name == "Keycard" and item.RoomNumber.Value == door.RoomNumber then
            unlocked = true
            break
        end
    end
    if unlocked then
        -- Open the door (e.g., change transparency, canCollide, etc.)
        door.Transparency = 0.5
        door.CanCollide = false
        wait(3) -- Wait for 3 seconds before closing the door
        door.Transparency = 0
        door.CanCollide = true
        unlocked = false
    end
end

door.Touched:Connect(checkKeycard)
```

Step 4: Create a system for distributing keycards to players
- This can be done in various ways, such as giving the keycard to the player when they spawn or having an NPC give the keycard to the player when they interact with it. Here's an example of giving the keycard to the player when they spawn:

```lua
local function giveKeycard(player)
    local keycard = game.ServerStorage.Keycard:Clone()
    keycard.RoomNumber.Value = 1 -- Change this to the room number you want to assign to the player
    keycard.Parent = player.Backpack
end

game.Players.PlayerAdded:Connect(giveKeycard)
```

Remember to place the keycard model inside the ServerStorage and customize the room numbers as needed.
