## PhysicsWheelJoint(PhysicsHandle)

Create a joint from a physics handle.

NOTE: You must ensure that the physics handle represents the correct object type otherwise hard to detect bugs can occur.

```csharp
public PhysicsWheelJoint(PhysicsHandle physicsHandle)
```

### Parameters

**** (\[PhysicsHandle]\(/engine/6000.5/script-reference/unity/u2d/physics/physicshandle)): The physics handle to use.

## PhysicsWheelJoint(PhysicsJoint)

Create a [PhysicsWheelJoint](/engine/6000.5/script-reference/unity/u2d/physics/physicswheeljoint.md) from the specified base joint. The provided joint must be a joint type of [PhysicsJoint.JointType.WheelJoint](/engine/6000.5/script-reference/unity/u2d/physics/physicsjoint/jointtype/wheeljoint.md).

```csharp
public PhysicsWheelJoint(PhysicsJoint physicsJoint)
```

### Parameters

**** (\[PhysicsJoint]\(/engine/6000.5/script-reference/unity/u2d/physics/physicsjoint)): The base joint to cast.
