Avirox's Rotation Tutorial Adapted to NetQuake

[mh]

I wouldn't mind a copy of it, just to test that my fix actually does work with it, before you make any changes to your own engine.

(deleted stuff that wasn't actually needed; mental note to self: read the original code first!!! )

Also note the nifty "sv_novis" cvar.

Confirmed, adapted mh's fix to FitzSDL/QS/RMQ engine. Works like a charm. Giant rotating bmodels, here I come.

Oddly enough, it also works perfectly with Enhanced GLQuake (aguirRe's engine) and he doesn't seem to have done anything to particularly fix this one - although I haven't looked too far yet. It does suffer from a "keyname too long" Sys_Error when parsing globals though, on account of the fact that he reduced the max key name length to 32 (from 64).

Yeah, but I guess it doesn't rotate there.

There is also no flicker when the offending thing is turned into a simple func_wall.

The problem only appears if the thing rotates, and the engine actually supports the rotation, I think.

[mh]

Of course, you're right (and you had mentioned it before now that I check back).

It really should rotate the bbox, then build a new bbox around the rotated coords instead. I wonder though, would it still be possible for an entity to exceed 16 leafs even if that was done? I had originally put my code in to fix the very same problem with an elevator in apsp1.

I wouldn't dispute that handling the bbox better is one way of fixing this specific problem (and should probably be done anyway), but I would argue that it is more of a general problem which needs more of a general solution. It's perfectly possible to construct a huuuuuge brush model that exceeds 16 leafs without even having it rotate, for example, and we haven't even touched on huge alias models yet.

r00k: Like Baker said, start with phat map capacity, skyboxes, fog, alpha, support -sndspeed 44100, raise static entities limit to like 1024, raise max_channels, modify Read/WriteCoord for higher map size limit and include this rotation stuff with the smooth angles fix and the flicker fix.

RMQ's engine source is available at my blog. We declared our collection of hacks protocol 999.

We have this evil plan to add csqc support, so be warned.
