Dependencie(s)
-
ioctl-napi, version 0.3.0.
This library communicates with game controller Linux' driver. In C language, to communicate with driver, we use "ioctl" function.
-
python-struct, version 1.1.3
This library permits to facilitate data transmission to controller driver by creating Bytes Array with a kind of variables definitions. As its name indicate it, it's a port the struct library from Python.
HOW TO USE
-
Get Character device path of game controller
- If plugged, unplug your game controller
- Then have a look, with ls command, on the folder /dev/input/.
- Check the list of files which begin by JS
- Plug your game controller and look again on the folder /dev/input/.
- A new JSx file should have appared -> Memorize the path, it's necessary to create a GameController object
-
Needed files
In the same folder, have the following files :
- GameController.js
- input.js, porting of C constants, found in Python code
- ioctl_macros_and_constants.js , porting of C macros for ioctl function. Currently not implemented in ioctl-napi NodeJs library :-(
-
Optionnal files
- json file of buttons and axes mapping (see the example in folder "json").
-
Try it !
In your nodeJs script, create a GameController object with the character device path of your controller. Then catch events 'GameControllerEvent'.
To help you, have a look in folder "examples"
