Negative Yaw? (Sdk)
Negative Yaw? // Sdkrunay@cyberjunkie.com (runay)Mar 1, 1999, 7:09pm
Hi,
Don't know what I'm doing wrong but somehow I'm getting a negative AW_AVATAR_YAW (-1800) when facing south (according to the SDK docs it should be between 0 and 3599). Any ideas? Runay edward sumerfieldMar 2, 1999, 1:20pm

<html> <body bgcolor="#D8D0C8"> Are you saying that if you are facing east then it will report 900? <p>It is supposed to report 0 as North, 900 as West, 1800 as South and 2700 as East. My trig functions are based on yaw/10. If it didn't do that I would expect my deer to be running in all kinds of strange directions.

Yes I came to the same conclusion after checking some variables.
N = 0 S = -1800 W = 900 E = -900 So, going counterclockwise (left) it goes from 0 to 1799 and clockwise (right) it goes from -1 to -1800. This means that values on the West side are OK but values on the East side will yield incorrect results. Weird, but I guess I can convert this before calling any functions.

I've also noticed this rather strange behavior, on the other hand, when
setting the yaw, 0-3599 works fine..... /Baggis [View Quote] decastro@cable.a2000.nl (xelag)Mar 3, 1999, 11:25am
In my experience, the SDK doesn't seem to mind if you write East as
-900 or 2700, both seem to be treated correctly. Querying property I found out that some objects have their yaw stored as negative angles, maybe due to a clockwise rotation. I myself use only positive values. XelaG. On Tue, 2 Mar 1999 18:35:46 +0100, "Walter Knupe" <wak at faber.ping.de> [View Quote] > >Well, i have.

Thanks all, I finally got it to work. At last I can finish my Holodeck
experiment. Computer, end program ;-) Runay [View Quote] >Hi, > >Don't know what I'm doing wrong but somehow I'm getting a negative >AW_AVATAR_YAW (-1800) when facing south (according to the SDK docs it >should be between 0 and 3599). Any ideas? > >Runay |
