Asshault is an in-browser action game started in 2013 to play around with game feel, or juice. Juice, among other things, comprises effects such as camera shake, particles, and sounds.
This is a for-fun project! I get to do things I don't usually get to do: animations, sprites, sounds, game ideas and the like. As such, the code is hacked together, and should really be refactored from the current prototypal inheritance into an entity-component system.
Some of the more interesting features and optimisation techniques I've used/experimented with here include:
- Flexible upgrade system with constraints, along with a flexbox UI for available upgrades
- 3D camera shake; affects UI (CSS)
- Triple canvases, one for decals, one for drawing, and one for fading effects trails
- Proper HTML canvas resizing based off window size
- Simple spatial hash for faster collision detection
- JSON-based asset loading
- Simple sound system for playing sounds, with an audio compressor attached
- Simple sprite management and rendering system
- Dirty detection of text for rendering on canvases (big perf hit)
- Waves/levels
- Sprite-based effects
- Animated sprites
- Highlighting in-canvas objects on hover of HTML elements
- Dynamically throttling effects to get a target 60fps
