And then other threads I dont know about.

I'm a total newb as for reading crash logs, I guess from the log that it probably got stuck at my function normAngle2 ?

my function normangle2 goes like this

Code:
float normAngle2(float angle) //returns an angle between -180 and 180
{
    while(angle<-180)
    {angle+=360;}
    while(angle>180)
    {angle-=360;}
    return angle;
}

which should work if i'm not missing something...

if it hung, then that only tells you that you were in an infinite loop and that one of the things it was doing was in that function.

So your loop issue is probably above that function somewhere. Or possibly you are passing a really freekin huge float into that function and it's taking a long time to get to the -180 to 180 range?

If you pass any suitably large negative or positive number (such that adding or subtracting 360 results in exactly the same float) or any NaN into that, it'll loop forever. Don't do those things Wink

Try using fmod() instead.

Oh right, it might have been a NaN problem...

And you're right, fmod does the same thing with constant time and no risks...

Thanks
