MvYawRightSpeed --- What does the value mean?

by Jay Barnson · in Torque Game Engine · 06/04/2007 (1:53 pm) · 1 replies

I'm at work, so I don't have the source code handy... wondered if anybody who knew the answer could shout it out.

What does the value of mvYawRightSpeed and mvYawLeftSpeed really mean? I thought it might be radians per second, but it's moving much too fast for this. Is it radians per frame (in other words, framerate dependent?)

I'm used to just sticking in some value that "feels right," but for some stuff I'm working right now I'd like an exact turn rate.

    Okay --- I'm home now, and was able to look through the code. Did some digging through, though not as extensively as I'd like...

    It looks like this is the amount of rotation in radians per "tick", or 0.032 of a second (31.25 ticks per second). Not framerate dependent (I should have realized this, but I haven't mucked with the source code in a few months and I have a terrible memory).

    So if you are looking at radians per second, just multiply it by 0.032 and it should work out. At least it seems to work for my purposes. Hopefully this might be of value to someone else.
