+title: Kinematic physics
+brief: This example shows a simple setup with a kinematic physics objects. The difference between dynamic objects, simulated by the physics engine, and kinematic objects, that are user controlled, is clearly seen here.
+scripts: kinematic.script
+---
+
+![kinematic](kinematic.png)
+
+The setup consists of three game objects. The *game.project* physics *GravityY* property is set to -500 to match the scale of the setup.
+
+block
+: The square stone block. Contains:
+  - A *Sprite* component with the stone block image.
+  - A *Collision object* component. The *Type* is set to `KINEMATIC`. A box *Shape* matching the sprite image is added to the components.
+  - A script that moves the game object to where the user clicks.
+
+block2
+: The rectangular stone block. Contains:
+  - A *Sprite* component with the stone block image.
+  - A *Collision object* component. Also has *Type* set to `DYNAMIC`, *Friction* set to 0 and *Restitution* to 1.0. A box *Shape* matching the sprite image is added to the components.

+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. 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.
+2. Store a flag in `self` (the current script component) to indicate if the game object is moving or not.
+3. If we receive an input action named "touch" and it is pressed then run the following.
+4. If the `moving` flag is not set.
+5. Disable (don't show) the help text label.
+6. Set the `moving` flag.
+7. Create a new position called `pos` (of type `vector3`) where the user clicked.
+8. Animate the game object's ("." is shorthand for the current game object) position to `pos`.
+   When the animation is done, call the function `landed()`.
+9. The function `landed()` is called when the animation is done. It just resets the `moving` flag
+   so subsequent clicks will result in a new movement.
