SetAngularVelocity() rotates which way?

by Tim Doty · in Torque Game Builder · 04/17/2005 (2:05 pm) · 4 replies

I could have sworn this was working as expected, but I just tried it on a clean application and it behaved the same.

Basically, angles measure in degrees from 0 being vertical (pointing up) in a clockwise fashion. Fine, no problem. So why does setAngularVelocity(20) rotate counterclockwise?

Because that was a bug. ;)

I can't believe this one wasn't spotted earlier! Amazing how slippery those damn bugs are.

ROFL!!!

I've spent the better part of 20 hours trying to figure out why my bees all turn right when the queen bee hangs a left :-)

Between reversing angles and adding or subtracting 90 between formulas and methods, I actually made a few of the bees sick enough to lose their lunches all over the monitor :-)

Next are cows, then people. It's amazing how close the herding AI is between the two :-)

Be sure to let us know when you get down to the people version--I know I for one am very interested in squad movement from a herding/flocking perspective!

@Melv: Well, when I saw it at first I was convinced there was something in my code because I'd gone over the angle stuff a month ago. Turns out due to an update issue I'd ended up using setRotation() rather than using setAngularVelocity() before noticing the behavior (obviously I figured out what I was doing to make the updates an issue and am using angular velocity now).
