joy
The module contains global variables representing the state of the one-button joystick. If the program is not using any joystick driver, the state of these variables is undefined.
To actually use this module, an appropriate joystick module must be used, such as c64_joy, nes_joy or gb_joy.
sbyte input_dx
Horizontal joystick movement. 1 if right, -1 if left, 0 if neither.
sbyte input_dy
Vertical joystick movement. 1 if down, -1 if up, 0 if neither.
byte input_btn
1 if main button pressed, 0 id not pressed.
void reset_joy()
Resets the state variables.
The default implementation resets only the main button.
May be overridden by a strong alias on some platforms that have more buttons.
null_joy_default
This module set the default joystick to no joystick.
alias read_joy
A reserved name for reading the default joystick.
mouse
The mouse module automatically imports the x_coord module.
The module contains global variables representing the state of the mouse. If the program is not using any mouse driver, the state of these variables is undefined.
To actually use this module, an appropriate mouse module must be used, such as c1531.
x_coord mouse_x
Mouse X position.
byte mouse_y
Mouse Y position.
byte mouse_lbm
1 if the left mouse button is being pressed, 0 otherwise
byte mouse_rbm
1 if the right mouse button is being pressed, 0 otherwise
