Sorry if the title isn't self explanatory. I've worked previously on the development of many small indie games for computers, but never really bothered on developing anything for a console, until recently when I got accepted for an indie development program for a well known game console. The games I'm working on (as most console games) will use the analog sticks for moving the character and rotating the camera, so far so good... except that the analog sticks don't work as I thought they would. When the analog stick is facing up, the "value" returned is pi / 2 (90°). When it's facing to the left the value is 0. When it's facing down, the value is (-pi / 2) (-90° ??) and when it's facing on the right the value is either -pi (-180° ??) or pi (180°). And obviously there are values in between all of those.
Small "ascii art" to demonstrate what I mean.
^ pi /2 +- pi < > 0 V -pi /2
The values that I don't get are the negative ones, how can I convert those negative values to an actual circle, so that I get a value between 0° and 360° (0 and 2 pi)?
Sorry if the question might sound stupid, I'm really new to console development. At first I thought I would ask in the official developers forum for this game console, but I thought that a public resource like stack exchange might be better since, I'm most likely, not the only one that has to deal with this, and probably other consoles have the same mechanism too.
