This project is a VR Escape Room challenge developed in Unity using the XR Interaction Toolkit as part of the Unity VR Development Pathway. The experience focuses on implementing multiple interactive VR mechanics such as button interactions, password validation, object spawning, swipe detection using vector math, and constrained object movement. The player must solve a sequence of interactions to unlock and open the exit door.
The player must unlock the door by completing the following sequence:
1- Enter the correct 4-digit password using the keypad. 2- A keycard spawns on the bench. 3- The player grabs the keycard. 4- The player swipes the card in the reader beside the door. 5- The door lock disappears. 6- The player slides the door open to escape.
The scene contains several interactive elements:
- A keypad used to enter a password
- A display that shows the entered digits
- A bench where the keycard appears
- A keycard reader beside the door
- A locked sliding door
The keypad allows the player to enter a 4-digit password by pressing physical buttons.
- XR button interaction
- Cooldown system preventing button spam
- Each button press adds a digit to the password
- Input is limited to 4 characters
The entered digits are displayed on a screen object inside the scene.
- A GameObject acts as the display
- The display has a TextMeshPro (TMP) child component
- The TMP text is updated dynamically through a script
- Each keypad input updates the displayed characters
This provides the player with visual feedback on the password being entered.
When the player enters a password:
- The system checks if the entered digits match the correct password
- If correct, a keycard spawns on the bench
- If incorrect, the system resets and the player must try again
After entering the correct password:
- A keycard object spawns on the bench
- The card is configured as an XR Grabbable object
- The player can pick it up and interact with the reader
The keycard must be swiped through the reader beside the door. The swipe detection uses vector dot product calculations to determine whether the card was moved in the correct direction.
If the swipe direction is correct:
The padlock disappears The locking bar on the door is removed
Incorrect swipe directions do not trigger the unlock.
After unlocking the door, the player must slide the door open manually. The door movement is controlled using direction validation with a dot product.
Features:
The door can only slide in the correct direction Movement in the wrong direction is prevented
This ensures the door behaves like a physically constrained sliding door.
