+title: Joint physics
+brief: This example shows a simple setup with a dynamic body physics object and two dynamic wheel physics object joined together with a joint of type "hinge". The hinge joint can simulate an axle or a pin on which other object is rotating in respect to the base. The example shows how to create, destroy and change properties of the joints.
+scripts: hinge_joint.script
+---
+
+![hinge_joint](hinge_joint.png)
+
+The setup consists of four game objects. The *game.project* physics *GravityY* property is set to -500 to match the scale of the setup.
+
+body
+: The square stone block. Contains:
+  - A *Sprite* component with the stone block image.
+  - A *Collision object* component. The *Type* is set to `DYNAMIC`. A box *Shape* matching the sprite image is added to the components.
+  - A script that joines the wheel game objects to to the body and reacts to user input by changing the direction of the rotation of the hinge joints.
+  - A label with an instruction to the user.
+
+frontwheel
+: The cirular metal wheel. Contains:
+  - A *Sprite* component with the metal circle image.
+  - A *Collision object* component. Also has *Type* set to `DYNAMIC`, *Friction* set to 0.9 and *Restitution* to 0.1. A box *Shape* matching the sprite image is added to the components.
+
+backwheel
+: The same as above.
+
+walls
+: The outer walls. Contains:
+  - A *Collision object* component. The *Type* is set to `STATIC`. 4 box *Shapes* are added to the component. These are placed just outside of the game view.

+1. Store collision objects ids, vectors used for anchors and hinge properties used for creating joints in local variables.
+2. Tell the engine that this object ("." is shorthand for the current game object) should listen to input. Any input will be received in the `on_input()` function.
+3. Set a flag self.forward used to define the direction of the rotation of the joined wheels.
+4. Create a joint of type "hinge" (a revolute joint, a pin or an axle) between a center of frontwheel collision object and an anchor ((-60,-60) from the center) on body collision object with provided properties. Do the same for the second wheel.
+5. If we receive input (touch or mouse movement) we switch the direction of rotation of the wheels.
+6. Negate the current flag defining the direction.
+7. If the direction flag is true, we are going forward.
+8. Set the motor_speed property to 5 revolutions per second in clockwise direction.
+9. If the direction flag is false, we are going backward.
+10. Set the motor_speed property to 5 revolutions per second in counter-clockwise direction.
+11. Destroy a current joint for frontwheel and backwheel.
+12. Recreate the joints with new properties.
