The input system manages external input devices like a mouse and a keyboard.
Keyboard and mouse button input is done through a class called BinaryInput.
Binary input is an interface over a rebindable control scheme, with each having one or multiple asset-defined activators (keyboard or mouse buttons).
Binary inputs can be requested from the asset system:
#include "input/binary_input.h"
#include "managers/asset_manager.h"
const BinaryInput* jump_input = AssetManager::request<BinaryInput>("jump.keybind.xml");
bool still_jumping = jump_input->get_pushed();
bool just_jumped = jump_input->poll_pushed();
bool just_stopped_jumping = jump_input->poll_released();.keybind.xml assets have the following format:
<keybind>
<input code="KEY_SPACE"/>
<input code="BTN_LEFT"/>
</keybind>Keyboard an mouse input codes can be found at the end of this document.
Mouse movement input can be retrieved from the InputController class.
#include "input/input_controller.h"
double mouse_pos_x = InputController::get_mouse_x();
double mouse_pos_y = InputController::get_mouse_y();
double mouse_shift_x = InputController::get_mouse_delta_x();
double mouse_shift_y = InputController::get_mouse_delta_y();It is possible that in the future the system will be replaced with an event-based system.
It is also possible that a text input system will be added.
