Broken RotatePivot()

[Emon]

Right, so I decided to dig up this stale Space Noxx II level that I never finished, and I'm trying to attach my sun light to my skybox in some fashion. Actually attaching it didn't make it rotate around the pivot point of the skybox, so I tried RotatePivot() instead. It doesn't work either... My template is basically a ghost with light and 0x1 thingflags, and move=path as well as the needed frames.

Inside the pulse, the position of the sun is printed out, but it never changes (which is clearly visible while playing).

What could be wrong?

RotatePivot(); will rotate the sun around its own pivot, not around something else's.

Also, the move should be move=physics unless you are going to use frames to move it, which would be a lot easier IMO. Also the tpye=weapon should be used if you want to set the velocity or use ApplyForce() and have it use relative axis instead of world axis.

No, RotatePivot() rotates around a frame in the object, which you specify. I got it working, since before I didn't realize you needed to specify PYR in the frame for it to work. Only trouble now is getting it to match up with the sun in my skybox.

I did that, GBK, it didn't work. It does not make the sun light pivot around the center of the skybox, and that pivot is in a totally different area of the map.

Well I converted my skybox to a skysphere (made in 3ds max by spherizing the textured cube, no distortions or misalignments at all), or more specifically, a starsphere. Not only does it look much better, but aligning the light is much easier.

Then I realized a few minutes before posting this that instead of trying to find the proper values for RotatePivot() (for the frame that specifies pivot) to match up with the (2/4/6) angvel on my starsphere ((2/4/6) wasn't the same for the frame on the RotatePivot()), I can simply use another RotatePivot() on my starsphere, and once I find good values for that, I'll just use them on the moving light. http://forums.massassi.net/html/redface.gif
