Tutorial: Adding Alpha Transparency to stock GLQUAKE

[Baker]

Baker you are a life saver! I've been trying to figure out getting alpha to work on brush models in ezquake. I'll give this a shot tomorrow night, and hopefully if it works the ezq devs will add my alpha .patch to the SVN build along with your brush alpha method. Thanks!

MSG_WriteFloat (msg, alpha);


I'm sorry, but... EGADS!
the first float is redundant, the second float is 4 times as large as is really useful.

looks good other than that though.

currently, this tutorial creates an engine that is only good for single-player, and won't even be able to read stock quake demos. might be good to:

1. change the protocol number so other clients will know they can't talk to this modified server, and can't play demos recorded with this modified client.

2. have the modified client check for protocol version and not read the extra bytes if protocol == 15, otherwise you won't be able to read stock protocol 15 demos.

3. get rid of most of the #ifdef GLQUAKE lines, otherwise the win and gl compiles from the same codebase won't even be able to talk to each other. The only thing winquake should do differently from glquake is ignore transparency when rendering. The network code and server-side stuff should be identical between the two builds.

Exactly.

I think "Winquake" should simply not render transparent brush entities - so you can still look through windows. All other transparent entities should just be solid in software.

Sure, you'll alert monsters etc - but that's the mapper's problem. Monsters behind an .alpha func_wall really should be alerted, too.

Then add alpha transparency to stock winquake too to make it fair - just rip the code from Quake2!
