4.4.3 Joystick

- -

(use-modules (sly input joystick))
-

- -

Joystick hooks, signals, and procedures. -

Before using joystick procedures, you must first call the -initialization procedure enable-joystick. -

Scheme Procedure: enable-joystick: Initialize joystick module. -

- -

Scheme Procedure: joystick-num-axes idx: Get number of axes of joystick at idx. -

- -

Scheme Procedure: joystick-num-buttons idx: Get number of buttons of joystick at idx. -

- -

Scheme Variable: joystick-axis-hook: This hook is run whenever a joystick motion occurs. Procedures added -to this hook should accept three arguments: which, the joystick -ID; axis, the axis ID; and value, the motion coordinate. -

- -

Scheme Variable: joystick-button-press-hook: This hook is run whenever a joystick button is pressed. Procedures -added to this hook should accept two arguments: which, the -joystick ID; button, the button ID. -

- -

Scheme Variable: joystick-button-release-hook: This hook is run whenever a joystick button is released. Procedures -added to this hook should accept two arguments: which, the -joystick ID; button, the button ID. -

- -

Scheme Variable: raw-axis-min: -32768 -

- -

Scheme Variable: raw-axis-max: 32767 -

- -

Scheme Procedure: axis-value-raw idx axis: Create a signal on the axis at axis of the joystick at -idx; joystick axis values are stored in a signed 16 bit integer -and so, values range from [raw-axis-min, raw-axis-max]. -

- -

Scheme Procedure: axis-value idx axis: Create a signal for the value of axis on joystick idx; -values are scaled to the range [-1,1]. -

- -

Scheme Procedure: button-down? idx n: Create a signal for the state of button n on joystick at -idx. -

- -

Scheme Procedure: make-directional-signal idx x-axis y-axis: Create a signal for a directional pad or analog stick with x -and y axes. Values are scaled to the range [-1,1]. -

- -

Scheme Procedure: make-directional-signal-raw idx x-axis y-axis: Create a signal for a directional pad or analog stick with x -and y axes. Values range from [raw-axis-min, -raw-axis-max]. -

- -

Scheme Procedure: axis-scale raw-value: Map raw-value in the range [raw-axis-min, -raw-axis-max] to a value in the range [-1, 1]. -

- -

Scheme Procedure: joystick-name joystick: Return the name of joystick. -

- -

Scheme Procedure: num-joysticks: Return the number of joysticks available. -
