Bevy Input Map

Input Map decouples gameplay code from device specific input api. By converting user inputs from different input hardware into game specific actions, eg. keyboard "Space" or joystick "A" can be mapped to "Jump" Action. This improves the overall code quality, by keeping the gameplay code separate from input code.

Usage

Add to Cargo.toml dependencies [dependencies] bevy_prototype_input_map = "0.1"

In code ```rust fn main() { App::build() ... .addplugin(InputMapPlugin::default()) .addstartupsystem(setup.system()) .addsystem(system.system()) .run(); }

fn setup( mut inputmap: ResMut, ) { inputmap .bindkeyboardpressed(KeyCode::Return, "SHOOT") .bindmousemotion(Axis::YNegative, "AIMUP") .setdeadzone("AIMUP", 0.1) }

// system fn system(inputmap: Res) { if inputmap.isactionactive("SHOOT") { println!("Bang..."); } ```
