Function Documentation

◆ joypad_get_state()

uint8_t joypad_get_state ( uint8_t controller )

MSX Get the status of the joystick buttons and levers.

Get the status of the two trigger buttons and eight-way lever of the specified joystick (or SPACE key and arrow keys of the keyboard).

Parameters

controller

joystick number

0 : keyboard (the arrow keys and the SPACE key)
1 : joystick #1
2 : joystick #2

Returns

status of buttons.
the following bits will be 1 if corresponding buttons / keys were pressed or will be 0 if released.

bit #0 : VK_UP
bit #1 : VK_DOWN
bit #2 : VK_LEFT
bit #3 : VK_RIGHT
bit #4 : VK_FIRE_0
bit #5 : VK_FIRE_1

Note: Each bit of the return value is independent and dedicated to the corresponding button/key. Therefore, a single call to joypad_get_state() can be used to get the state of all buttons on the specified joystick.; For example, if you push the joystick lever to the upper right and press trigger #1, bit #0, bit #3, and bit #4 of the return value will be set to 1 (i.e., the value VK_UP | VK_RIGHT | VK_FIRE_0 will be returned).
