Problem with conveyor style cogs

[money•bie]

When I've recently gone to make a rounded waterfall (i.e., the trajectory of the waterfall is protrusive, so as to seem realistic), I've noticed that basic conveyer cogs seem to animate the surfaces at different speeds (basically, the larger surfaces are slower than those small). So, to cut to the chase, I'm having trouble manipulating the cogs to make the surfaces animate in concordance.

I vaguely recall Halucid/SniperWolf working on a cog that dealt with conveyors on sloped surfaces. I may be misunderstanding you, but ask one of them. I'll look around a bit for the thread.

Scroll down to SniperWolf's last few posts.

Curse you CavEmaN, I'll get you !!!!

I noticed that scrolling surfaces never seem to properly line up, even though I line them up in Jed =\ *goes to link*

That's exactly what I was looking for, thanks! I had actually come to the same conclusion as halucid and had tried the same method he suggested where each surface had their own vector, but, strangely, it didn't work. I’d put it down to the fact that my math -> cog skills are, shall we say, unrefined.

Weird, I finally got the chance to use it, and it doesn't work.

Looks like you didn't copy correctly. From the looks of it, the forums messed up one of the lines...
# ==================================================
======================================

That all needs to go on one line. Otherwise, the === aren't properly commented out, and the cog won't work.

[money•bie]

Actually, I corrected that in the final cog file. It's just something it does everytime you subject it to [code] brackets.

But maybe there's something else eluding me that was screwed up by the forums. Help? :\

[zagibu]

Yeah, it messed up your <> signs on code line two and three.

[money•bie]

Er.. I don't see what you're talking about. Would ya mind editing it in Notepad or whatever and attaching it?

[LKOH_SniperWolf]

Try this. It should work. I think I got all the forum stupidities out...

[LKOH_SniperWolf]

Just change the extension, and it SHOULD work, unless I'm missing something...

[money•bie]

Still doesn't work. :\ I'll probably just end up doing away with the curved waterfall if I can't figure out the problem.

[LKOH_SniperWolf]

Fixed... Apparently after halucid got it, I modified it slightly. Because of the way the vectors were done, this left an error if the X chosen was 0. This has been fixed. The appropriate file is attached below. You should have no problems whatsoever. (This has gone through several more tests. (I should note, I don't think in original testing, 0 was ever used for X...))

I gotta say, I really appreciate your persistence. It works bootifully.
