Hinge Joint Door

This guide was written for Patch 3 and may contain outdated information.

This is a simple guide for using joints to create a door!

Creating a prefab

Make a prefab for the door, inside, add a GameObject called JointDoor, this is used for the door itself.

If you don’t have a frame or anything outside the door that isn’t supposed to move, instead add the following components to the root of the prefab.

Add an InteractableHost, Hinge Joint, and a Rigidbody to the JointDoor GameObject. (Or the root)

The Rigidbody

You can do whatever you want with this, as the setting varies depending on the type of door you’re making.

The InteractableHost

You can just leave this component alone.

The Hinge Joint

Add any colliders, models, or grips as children under the JointDoor GameObject.

• You can leave the Connected Rigidbody empty, or you can give the root a Rigidbody, set it to Kinematic, and then connect it to that, but as far as I know, there’s not much point in doing that.
• The anchor is what the object will rotate around. You’ll usually want to set this to the side of the door, assuming it is a similar model to the one in the GIF.
• Set some of these numbers to 0 or 1, using the “Edit Angular Limits” view to see the rotation. It’s important you set this correctly.
• At its current settings, the door has no rotation limit; if you want it to stop moving at a specific rotation, check the “Use Limits” toggle. Under “limits,” you can adjust it however you want. Use “Edit Angular Limits” to view the object’s limit.
• Lower Break Force or Break Torque to make your door destructible when positional or rotational force is applied. It’s set to infinity by default.

Here’s the settings I use most of the time:

You can play around with the rest of these settings. Although usually just changing the settings I listed works fine though.
