How to Create Custom Colliders for a More Realistic 2.5D World

In this tutorial, you'll learn how to create custom colliders to control where avatars can or can’t walk—perfect for making avatars walk behind tall buildings or block off specific areas to enhance realism in your world.

1️⃣ Open Settings

When you're inside your world, click the Settings button at the top-right corner of your screen.

👉 This opens the customization menu.

2️⃣ Click “Add Map” and then “Add Collider”

Inside the Settings panel:

1. First, click the Add Map icon (it looks like a map with a plus sign).

2. Then click the Add Collider button.

3️⃣ Draw the Collider Area

Move your mouse to where you want to block movement (for example, the base of a tall building).

• Left-click and hold, then drag your mouse to draw a rectangle covering the area you want to set as a collider.

• Release the mouse once you’ve outlined the area.

4️⃣ Confirm the Collider Placement

After selecting the area, click the pink “Add Collider” button on the right panel to confirm.

5️⃣ See the Collider Preview (Temporary Yellow Box)

You’ll see a yellow rectangle appear over the area you just set. 👉 Don’t worry—this yellow box is only visible to you (the world owner) to show where the collider is.

To finish, click the “Done” button at the bottom of the screen.

✅ After clicking Done, the yellow rectangle will disappear—but the collider will stay active, blocking avatars from walking through it.

✅ Extra Tips:

• You can add multiple colliders by repeating this process to cover different parts of your map.

• Use colliders creatively to let avatars walk behind buildings, while still keeping certain areas blocked for realism.

Always remember to click “Done” to save your changes when you're finished adding colliders!
