Hey
Im having ALOT of trouble in figuring out how to map the gun locations on sprites in the shan resource. Basically, the 'orbital path' never seems to track the ship properly.
In addition, when I render the sprites and insert them into the shans, the very centre pixel of the render is never the part of the ship that stays in the same place, is this a CRITICAL problem? (......this is hard to explain) Must the sprite spin on an axis which is exactly centered in the window?
I hope this all makes sense. Any help would be apreciated.
cheers

Sounds like you need to start clipping from the center of the image. Try using Dr. Ralph's "Sprites" package to solve this problem.
Play around with the Up/Down Compress X/Y fields while you're at it to generate elliptical orbits; look at the values for similarly sized ships in the default scenario.

At what angle are you rendering your ships?
Actually, the center pixel of the render is not going to be the same (location on the ship) if you render the ship at a non-vertical angle. What's important is that the ship rotates about a point that's centered in the middle of the render. Did that make sense to you? Basically, if the origin is centered in the middle of the render, and the ship rotates about that point, then you should be fine.
To get the orbital path to track the ship correctly, just play around with the up and down compressions. If you rendered the ship at 45° above the plane of the ship, then you could simply copy the compression settings from the ship data files.

Ive really just been rendering ships at various angles for now, just experimenting, ill probably render them the same as the existing nova sprites, 45deg?
Btw, is there an easy way to make sure the point the ship rotates on is centered in the render? - Or is it basically just doing it by eye?
Thanks,
Wait a second........ I think I see what's going on. If you don't rotate around the camera interest, you're basically screwed......... What program are you using?

what? Why would you rotate the camera around the interest? You be better off setting the interest at <0,0,0>, and having the ship rotate around the origin as well. Rotating the camera will cause the light to only hit one side of the ship (making it look as if the light is rotating with the ship), rather than... yea....

I meant to rotate the ship around the camera interest. It doesn't matter where that is as long as the two converge.
Does anyone know what the UpComp.XY and DnComp.XY fields do?

Ill try and give an excuse, but well, whats the point?
<edit> ive just had a broswe through the ship files and well, all the vales are the different in the upcomp.XY and dncomp.XY fields, and i find this really confusing given that all the ships were rendered at the same angle. Im sure there is an easy explanation of how they work, but could someone 'tutorial' me in it, you know, the one with big pictures, big writing, and for ages 5+. <edit>

I found that using the shuttle's up and down comp values generally works.

Go to the delta-v subscribe page on ambrosias web page, or whatnot, and download the delta-v.mbox file or whatever it is, the gigantic text file which contains all the posts to the list ever made. Somewhere in the list someone posted an unscientific and silly way to find the correct upcompress dncompressxy etc fields. It didn't seem to make much sense logically, but it worked for someone I think as a good way to find the right values to make the exit points work right.

I dont s'pose youve got a extract of the text on hand do you?
thx
