A simple-to-use input manager for the Bevy game engine that empowers players and makes accessibility easy.
- Make accessibility easy.
- Players can create and share custom input configs. Configs can be merged at runtime.
- Post acceptance delay helps players with conditions like Parkinson's avoid unintended key presses.
- Toggling continuous input helps players who physically cannot hold down a button for long periods of time.
- Macro support coming soon.
- Offer a unified, abstracted view of input.
- Games should be agnostic of specific input devices.
- No more manually gathering keyboard, mouse and gamepad input from multiple sources.
- Never allow the game to crash, but provide clear and direct feedback when something goes wrong.
- Scans player-made keybinding configurations and composes a report containing detailed feedback.
- Recognise the existence of different kinds of input (axis, dual-axis, continuous and pulse), and leverage the type
system to differentiate between them at compile time.
- DualAxis: Inputs a direction along two axes. E.g. an analog stick.
- SingleAxis: Inputs a direction along one axis. E.g. the mouse wheel.
- Continuous: Is active continuously. E.g. while a button is held down.
- Pulse: Pulses occasionally. E.g. clicking left mouse button.

- Macro support
- Recording and playing back input sequences
- Helper functions for implementing a key re-mapping settings screen in-game.
- Full local multiplayer support
- Support for on-screen button prompts
- Different input contexts
- Maybe a tie-in to GUI?
