You can use the Lock device to customize the state and accessibility of a door. Locking and unlocking can be triggered by player actions or by other devices.
This device only works with assets that have a door or gate attached.
Locking a Door
The most basic use for the Lock device is — you guessed it — locking a door!
Connect the lock to a Button device for easy toggling between locked and unlocked states.ndefined

Design Tip
The Lock device can very easily be connected to a Conditional Button device to give the added requirement that aplayer possess the correct key. The key can be anything: an actual key, a specific weapon, a fish, or anything else you can imagine.
Escape Room Exit
Locks are a core part of any escape room or puzzle game where players must solve a puzzle to get out of an area. In this example, you’ll set up a basic puzzle that unlocks the player’s exit when solved.

Configure the following event on the master switch so that when turned on, it checks the puzzle switch, unlocks the doors, and plays the audio player.

Duplicate the puzzle switch two more times and place them strategically around the building. Duplicating the device will ensure that they retain the correct direct event bindings.
You now have the basic functionality for an escape room using locks!
Design Tip
To add some more tension to a puzzle like this, try giving the player some type of time limit. That could be as simple as a Timer that locks them inside permanently if they don’t complete the puzzle in a certain amount of time. Or, think of more creative ways to limit the player, like slowly doing damage to them while inside or filling the room up with water!
Build a Door Parkour Game!
When combined with other devices like the Timer, the Lock device can produce very interesting results. In this example, you’ll create a parkour map using opening and closing doors as a primary mechanic!
Devices Used

Set Up Your Parkour Island
Begin by setting up your parkour island using floors from the Colossal Coliseum Floor & Stair Gallery and doors from the Colossal Coliseum Wall Gallery. While setting up the island, test out the jumps yourself to dial in the distances between objects! If you’re confused about how things should look, see the video above.
Place a floor floating high up in the air.
On the starting floor, place a Player Spawner.
Customize the Player Spawner so Visible in Game is set to Off
In front of the starting platform, place a few floors with doors on either side.
In front of this platform, place another floor up and slightly to the left.
Place a Prop Mover on this platform. Make sure that the device appears green while placing, which indicates that it is connected to the platform. Rotate the Prop Mover to point to the right.
Customize the Prop Mover:

In front and below this platform, place a bouncer from the Bouncer Gallery device.
Customize the Bouncer:
Way above the Bouncer, place another platform with a door in front.
Create a path of four horizontal doors with gaps between them, each one raised slightly from the last. Rotate them differently to create some variation.
After the last door, place another platform blocked by a door. This will be the ending point for the parkour course!
Place a Damage Volume on the ground below the parkour course.
Customize the Damage Volume:

Duplicate the lock and place duplicates on each door throughout the course. Duplicating the devices ensures that they retain the correct direct event bindings.
Set Up the Game End
Right after the final door on the ending platform, place a Trigger device on the ground.
Customize the trigger so Visible in Game is set to Off:
Place an End Game device somewhere where the player won’t be able to see it, and customize it with a Course Completed! victory callout.
Configure the following event on the Trigger device so that when the player reaches it, the game ends.
Event Select Device Select Function
Modify Island Settings
Make the following modifications to the island settings.
Go to Island Settings > Player.
Under Locomotion, change Glider Redeploy to Off.
Under Equipment, change Start With Pickaxe to No.
Go to Island Settings > Mode.
Under Spawning, change Respawn Time to 1 Second.
You now have a working parkour game using locks!
Design Tip
This example uses only one timer to control all of the locks, but consider having more timers to control each lock individually. This would give more control over each door, allowing you to set some to be quicker than others!
