Setting a particle's angle based on the mouse

Oh s*** ... I checked the ParticleSystem source just now, and I discovered a huge mess with the degrees/radians conversions. Oh, well. That's what we get for speedcoding.

I'm considering whether we should change everything to radians. I would prefer everything in degrees (which is more intuitive), but we can't (shouldn't) change the standard Lua math library. That's for another thread, though.

Wiki: yes, it will come, but I haven't even started on it yet. I need to make a template for Dokuwiki, integrate it with phpBB and probably make custom plugins. It's a big project in itself.

I myself prefer everything in radians. The reason is that this is what is used after elementary school, and every single sin, cos, atan2, or any other trigonometry function i have ever come across uses radians.

But the problem is that it's so damn... non-intuitive... unless we teach every newbie that up is pi/2, left is pi and down is 3pi/2...

I guess if we always remember that everything in LÕVE is in degrees, and everything in Lua is radians, we'll be fine

Could always make your own sin, cos, tan which uses degrees... But everything in radians will be more consistent; IMHO just add a function to convert between radians and degrees.
