Writing Joystick Code: Part 4: Difference between revisions

This is fine if you are using the joystick on your system. But imagine that you have worked out a brilliant button assignment scheme, using modifiers, so that the joystick is a joy to use. You want to post your code in the forum so everyone can use it.

There's a problem though. Different operating systems assign different numbers to the axes. Let's say that with a your joystick, Windows says that the Aileron axis is number 0, and Macs and Linux say it is axis 2. We have to change our format of the axis definition to

Unfortunately, there is no fixed relationship between axis numbering in the operating systems, and the information must be garnered form experience. Fortunately, the button numbering doesn't seem to change.

Here is a list of axis numbers for various joysticks. The list will be expanded as and when I get the required information. If you have axis numbers for a joystick not listed here, please post the information [http://flightgear.org/forums/viewtopic.php?f=24&t=17924 here]. Don't post the axis number as they are currently in the xml file, we already know them.
