Enjoy a new example in our engine: [examples/space\_shooter](https://github.com/castle-engine/castle-engine/tree/master/examples/space_shooter). Features:

- 

- Background (drawn efficiently as one quad, with texture repeating to infinity).

- Rockets (fired by the player’s cannons). Each rocker has a collider and can detect when it hit an enemy. Rocket can be “armed” (destroys enemies) or “not” (just a ball that bounces off enemies).

- Enemies, played by the _Mighty Rotating Rocks_! They just move slowly towards the player. You can shoot them to destroy.

Technically:

- The player is just a `TCastleScene` inside a `TCastleViewport`, with input events handled in `TViewMain`.

- Using `TCastleComponentFactory` to create rockets and rocks. Each of them is defined by a [reusable design](https://castle-engine.io/reuse_design).

- Using [behaviors](https://castle-engine.io/behaviors) to define various behaviors of rocks and rockets.

- Using [physics](https://castle-engine.io/physics) to handle collisions between rockets and rocks.

- Special component [TTilingBackground](https://github.com/castle-engine/castle-engine/blob/master/examples/space_shooter/code/gametilingbackground.pas) to draw a background that (seems to) repeat to infinity. This is a reworked version of an old example `background_tiling`.
