HID

Human Interface Device (HID) module provides APIs to access platform's input and output devices, like mouse, keyboard, controller, etc.

Types

• Luna::HID::ControllerInputState

  The fetched input state for one generic game controller.

• Luna::HID::ControllerOutputState

  The state to set for a controller.

Enumerations

• Luna::HID::ControllerButton

  Specifies controller buttons. These values can be bitwise-OR combined to select multiple mouse buttons if needed.

• Luna::HID::KeyCode

  A platform-independent key code mapping for standard QWERTY keyboard.

• Luna::HID::MouseButton

  Specifies mouse button. These values can be bitwise-OR combined to select multiple mouse buttons if needed.

Functions

• bool supports_controller()

  Checks if game controller input is supported on the current platform.

• ControllerInputState get_controller_state(u32 index)

  Fetches the input state of the specified controller.

• RV set_controller_state(u32 index, const ControllerOutputState &state)

  Sets the output state of the specified controller.

• bool supports_keyboard()

  Checks if keyboard input is supported on the current platform.

• bool get_key_state(KeyCode key)

  Checks the if the specified key on the keyboard is pressed.

• bool supports_mouse()

  Checks if mouse input is supported on the current platform.

• bool get_mouse_button_state(MouseButton mouse_button)

  Checks if the specified mouse button is pressed.

• Int2U get_mouse_pos()

  Get the position of the mouse cursor in screen space.

• RV set_mouse_pos(i32 x, i32 y)

  Sets the OS mouse cursor position. The position is based on the screen coordinates. This only works for platforms that support mouse input.
