• Live demo: https://www.danneu.com/elm-space-arena

A sloppy 2D spaceship shooter built with Elm to explore game development.

It's a work-in-progress with shameful code.

Clone

$ git clone https://github.com/danneu/elm-space-arena.git
$ cd elm-space-arena
$ npm install
$ elm make
$ npm start
Dev server running on <http://localhost:8080>

Technical Notes

• (x, y) starts at the top-left. x increases going right, y increases going down.
• position is always the center of an entity.
• Deploys to gh-pages branch done with https://github.com/X1011/git-directory-deploy

Optimization Notes

• obj.visible = false means container and all of its children's matrices won't be updated.
• obj.renderable = false means that the container will be updated but not rendered (use for culling).
• texture = Texture.EMPTY has no special cases. Sprite is rendered anyway.
