The Magic of Waiting: Making Platforms Disappear

Do you like building secret bases? Do you like traps that only work sometimes? Today, we will make a disappearing platform. It will vanish when you step on it. Then it will come back after a short wait. This wait is called a cooldown. It is like a video game power-up that needs time to recharge.

What You'll Learn

• How to make a platform hide and show up.
• How to use a variable to store a number.
• How to use Sleep to pause the game for a moment.
• How to connect devices using Verse.

How It Works

Imagine a trapdoor in a castle. You step on it. It falls down. You cannot walk on it for ten seconds. After ten seconds, it pops back up.

In Fortnite, we use a device called a Trick Tile. It can hide or show a platform. But we need a brain to tell it when to hide and when to show. That brain is Verse.

We need two things in our brain:

1. A Variable: This is like a box. We put the number 2.0 in it. This means "wait 2 seconds."
2. A Loop: This is like a merry-go-round. It goes round and round forever.

The code will do this:

1. Wait for you to touch the tile.
2. Hide the platform.
3. Wait for the time in the box (2 seconds).
4. Show the platform again.
5. Go back to step 1.

Let's Build It

First, place a Trick Tile in your island. Place a Prop on top of it. This prop is your platform.

Now, let's write the code. Copy this into a new Verse file.

# We need the Trick Tile device tools
using { /Fortnite.com/Devices }
using { /Verse.org/Simulation }

# This is the main script for our island
MyIsland := class(creative_device):

    # This is our Trick Tile device.
    # Drag your Trick Tile from the editor onto this property.
    @editable
    TrickTile : trick_tile_device = trick_tile_device{}

    # This is our "brain" that starts when the game begins
    OnBegin<override>()<suspends>:void=
        # We create a variable called 'wait_time'
        # It holds the number 2.0 (seconds)
        wait_time := 2.0

        # We start a forever loop
        loop:
            # We wait for a player to touch the tile
            TrickTile.ActivatedEvent.Await()

            # When touched, we hide the tile
            TrickTile.Disable()

            # We wait for the time in our variable
            Sleep(wait_time)

            # Then we show the tile again
            TrickTile.Enable()```

### Walkthrough

1.  `wait_time := 2.0`: This creates a box. We put `2.0` inside. This is our **variable**. It changes if we edit the number.
2.  `Sleep(wait_time)`: This is the magic pause button. The game stops for exactly the number of seconds in our box.
3.  `loop:`: This starts the cycle. It never ends. It keeps checking for players.

## Try It Yourself

Can you make the platform wait longer? Try changing the number `2.0` to `5.0`.

**Hint:** Find the line that says `wait_time := 2.0`. Change the `2.0` to `5.0`. Save your code. Play the island. Does it wait longer?

## Recap

You built a looping trap! You used a **variable** to store time. You used **Sleep** to pause the action. You used a **loop** to keep the game running. Great job, coder!
