+title: Box2D Motor Joint
+brief: Create and control a motorized Box2D joint from script using Box2D V2 and V3.
+author: Defold Foundation
+scripts: box2d_motor_joint_v3.script, box2d_motor_joint_v2.script
+thumbnail: thumbnail.webp
+---
+
+This example creates a motorized Box2D joint at runtime. It works with both Box2D V2 and V3 by attaching one script for each backend. Each script checks `b2d.get_version()` during `init()` and becomes a no-op when the other backend is active.
+
+Click or tap the window to reverse the motor direction.
+
+## What You'll Learn
+
+- How to get Box2D body handles from Defold collision objects
+- How to detect the active Box2D version with `b2d.get_version()`
+- How to create a pivoted motor joint with `b2d.joint.create_revolute()`
+- How to control joint motor speed with `b2d.joint.set_motor_speed()`
+- How to tune the Box2D V3 joint solver with `b2d.world.set_joint_tuning()`
+
+## Setup
+
+The collection contains a static `pivot` game object, one dynamic `arm` game object with a particle effect, and a controller game object.
+
+The `pivot` object marks the world point the arm should rotate around. The `arm` object is the dynamic body driven by the joint. The example uses a revolute joint with its motor enabled, because the revolute joint provides a stable hinge pivot while the motor drives the rotation.
+
+The controller has both backend scripts attached. Each script checks `b2d.get_version()` and only runs when the selected app manifest matches its Box2D backend.
+
+![setup](setup.png)
+
+The `game.project` of this example is configured to build with `/box2D_V3.appmanifest` by default. To test V2 locally after downloading the example, change `Native Extensions -> App Manifest` in `game.project` to `/box2D_V2.appmanifest`.
+
+![game_project](game_project.png)
+
+## How It Works
+
+Both scripts read `b2d.get_version()` once. `box2d_motor_joint_v2.script` only continues when the major version is 2, while `box2d_motor_joint_v3.script` only continues when the major version is 3.
+
+`b2d.get_body()` returns the Box2D bodies owned by the `pivot` and `arm` collision objects. The active script then creates a revolute joint between those bodies with `b2d.joint.create_revolute()`.
+
+The joint definition uses:
+
+- `local_anchor_a` on the pivot body
+- `local_anchor_b` on the arm body
+- `enable_motor` to turn on the joint motor
+- `max_motor_torque` to limit how strongly the motor can rotate the arm
+- `motor_speed` to set the current motor direction and speed
+
+The important part is the arm anchor. The pivot is placed in the collection as a visible reference point. The scripts convert that world position into the arm's local space, so the arm rotates around the same visible pivot instead of rotating around its center.
+
+Click or tap to reverse the motor with `b2d.joint.set_motor_speed()`. The V3 script also calls `b2d.world.set_joint_tuning()` to adjust the joint solver used by the Box2D V3 backend.

+3. Reverses the stored motor direction before applying the new speed.
+4. Reads the active Box2D backend version.
+5. Enables this script only when the project is running the Box2D V3 backend.
+6. Stops the script early when Box2D V3 is not active.
+7. Acquires input focus so this script can receive click or touch input.
+8. Gets the current Box2D world handle.
+9. Clears world gravity so the arm stays in the editor-placed setup.
+10. Tunes the Box2D V3 joint solver used by the motorized joint.
+11. Reads the editor-placed pivot position, which is the world point the arm should rotate around.
+12. Gets the Box2D body from the static `pivot` collision object.
+13. Gets the Box2D body from the dynamic `arm` collision object.
+14. Disables gravity on the arm body so the example focuses on the joint motor.
+15. Converts the pivot world position into the arm's local space using the V3 body helper. This keeps the arm rotating around the visible pivot.
+16. Creates a revolute joint with its motor enabled. The revolute joint provides the pivot, while the motor drives the rotation.
+17. Skips input handling if this script is inactive.
+18. Handles a click or touch press and uses it to reverse the motor direction.
+19. Destroys the runtime-created joint during cleanup.
+20. Releases input focus when the script or collection is unloaded.
