handler

Component that receives input events.

Members

on_key

putils::function<void(entt::entity window, int keycode, bool pressed), KENGINE_INPUT_FUNCTION_SIZE> on_key;

on_mouse_move

putils::function<void(entt::entity window, const putils::point2f & screen_coordinates, const putils::point2f & relative_movement), KENGINE_INPUT_FUNCTION_SIZE> on_mouse_move;

on_mouse_button

putils::function<void(entt::entity window, int button, const putils::point2f & screen_coordinates, bool pressed), KENGINE_INPUT_FUNCTION_SIZE> on_mouse_button;

on_scroll

putils::function<void(entt::entity window, float xoffset, float yoffset, const putils::point2f & screen_coordinates), KENGINE_INPUT_FUNCTION_SIZE)> on_scroll;

All these callbacks take as a first parameter the window entity in which the event happened.

The maximum size for these functors defaults to 64 and can be adjusted by defining the KENGINE_INPUT_FUNCTION_SIZE macro.
