Expand description

Maps raw inputs to game controls and exposes controls for respective player and their control source.

InputCollector::apply_inputs maps raw input to game controls and updates them.

InputCollector::update_just_pressed computes any changes in pressed buttons that may be stored on control.

InputCollector::advance_frame is used to mark that the input has been consumed, and update the prev frame inputs to current, to compute changes next frame.

Generic type param ControlMapping is HasSchema because it is expected to be a Resource retrievable on world.

Required Methods§

fn apply_inputs( &mut self, mapping: &ControlMapping, keyboard: &KeyboardInputs, gamepad: &GamepadInputs )

Update the internal state with new inputs. This must be called every render frame with the input events. This updates which buttons are pressed, but does not compute what buttons were “just_pressed”. use InputCollector::update_just_pressed to do this.

fn advance_frame(&mut self)

Indicate input for this frame has been consumed. An implementation of InputCollector that is used with a fixed simulation step may track what keys are currently pressed, and what keys were “just pressed”, (changing from previous state).

This saves current inputs as previous frame’s inputs, allowing for determining what is “just pressed” next frame.

fn update_just_pressed(&mut self)

Update which buttons have been “just pressed”, when input has changed from last frame and current input state.

This does not modify previous frame’s input, to do this use InputCollector::advance_frame.

fn get_control( &self, player_idx: usize, control_source: ControlSource ) -> &Control

Get control for player based on provided ControlSource.
