I think there is too much cconverting back and forth. When debugging you can convert the angle before displaying, but besides that there is no need to have angles in degrees. The developer never really has to work with the radians.

I.e. aiming and such. So the user will most likely only ever be aware of the actual angle an entity is facing in context of a compass heading. This is purely for the comfort of the developer so we can more easily work with game code and not lose our bloody minds doing so!… lol! -Know what I mean?… It's a whole lot easier working with 30 degrees rather than 0.5235987756 radians, yes? lol! Have a totally awesome night and hope the holidays are treating you and yours wonderfully! -Thanks for the great notes keeping this way cool topic happening!… Smiles, Cara :) On Dec 12, 2010, at 8:24 PM, dwill...@gmail.com wrote: Yes, but the actual value doesn't matter as long as you stick to using one or the other method. Under normal surcomstances it wont be shown anyway and only the angles that are displayed need to be converted. -original message- Subject: Re: [Audyssey] game objects in memory From: Cara Quinn <caraqu...@draconisentertainment.com> Date: 13/12/2010 1:53 am Hi Willem, right you are! -For me though, holy crap! I wouldn't feel at all comfortable dealing in radians all the time. lol! I prefer to work in degrees and just convert back and forth on the fly. I basically have two methods I send pointers to; one to get an angle which returns in degrees, and the other to set an angle which takes degrees. I personally just don't naturally think in radians, but there ya go. Have a terrific day!… Smiles, Cara :) On Dec 12, 2010, at 9:28 AM, Willem Venter wrote: Hi Cara and all. Thanks for the discussion. Reading all this was very informative and helpfull. An observation I might make is that if you work only in radians, multiplying and dividing with the constant (pi/180) becomes redundent. This will save some small calculation and simplify the code. If you really want to see the normal degree form of the angle you could just use standard functions to convert it back for displaying.
