Scenic Asteroids

This is an Asteroids clone written in Elixir with Nerves, more for fun and learning than for anything else. Also since the code (and behavior) is relatively simple, I hope that it can serve as an example for Scenic, Nerves, and as a simple poncho project.

It is licensed under the 3-clause BSD license (see LICENSE) for details.

Instructions

From the root of the repository run the following commands:

• Install scenic pre-requisites
• cd play_ui
• mix deps.get
• iex -S mix

Keys:

• W - Move up
• A - Move left
• S - Move down
• D - Move right
• SPC - Shoot an asteroid

Use the mouse to target the asteroids (or your finger if you're running with a Nerves touch screen)

Have fun!

Implementation Notes

SchedEx is used to implement the core animation timer which runs at a rate of 60 frames per second.

Collision detection is incredibly basic and non-performant. Ideally either scenic or a cooperating library would implement some collision detector helpers. If you're interested in collision detection then please contribute to Scenic issue #91.

Projects

• play/ - The main game logic
• play_ui/ - Run via scenic on the desktop
• fw/ - Run on a Nerves device with a touchscreen
  • Official Raspberry PI touch screen is supported

TODO:

• Get basic nerves install working on network
• Run scenic play application on nerves!
