Minimal Survivors

A 2D action shooter prototype by Brett Chalupa

Inspired by Vampire Survivors and the like. Made over the course of a week. The starting point for the experimental Exquisite Corps jam by the DragonRuby Game Toolkit community.

Minimal Survivors is dedicated to the public domain.

Built with DragonRuby Game Toolkit v3.24 Pro Edition (uses Standard features in the code but uses the Pro high DPI and bytecode features).

Controls

Move: WASD / Arrow Keys / Gamepad
Select & Fire: J / Z / Space / Gamepad A button

Developing

The engine files are not included in this source repository so that people can use whatever operating system they want. Also, if we open source it when it's done, it's easier to not have to deal with that.

Unzip the DragonRuby Game Toolkit engine zip
Delete the mygame directory
Clone the repository into the DRGTK engine folder with the folder name mygame: git clone git@github.com:brettchalupa/minimal_survivors.git mygame
Start DragonRuby, and make it awesome!

On the Code Architecture

The code is intentionally structured to make use of functions and args.state without any classes. A functional-ish approach. This follows in the spirit of DRGTK's docs.

Keyboard Shortcuts

There following debug-only shortcuts can be used to help make developing easier:

i -- reload the sprites from disk
r -- reset the game
0 -- render debug details
1 -- level up player
2 -- toggle player invincibility

Tests

Tests for methods live in app/tests.rb. Run the tests with from within your engine dir with:

./dragonruby mygame --eval mygame/app/tests.rb --no-tick --exit-on-fail
