## 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.
|
|
|
|
#### `sbyte input_dx`
|
|
|
|
Horizontal joystick movement. 1 if right, -1 if left, 0 if neither.
|
|
|
|
#### `sbyte input_dy`
|
|
|
|
Vertical joystick movement. 1 if right, -1 if left, 0 if neither.
|
|
|
|
#### `byte input_btn`
|
|
|
|
1 if main button pressed, 0 id not pressed.
|
|
|
|
#### `void reset_joy()`
|
|
|
|
Resets the state variables.
|
|
For platforms with more than one button, this resets only the main button state.

On those platforms use the platform-specific functions instead.

## `x_coord` module
|
|
|
|
#### `alias x_coord`
