water in halflife, coding question

[imkongkong]

not sure whether this goes into coding as it is not a esf code question, mapping, off topic, so i decided to post here

is it possible to have lagless water in half life? where it doesnt tremendously eat your fps if theres a large amount? i remember the esf island map by stryker wasn't at all very laggy... is there a way to code it in so that it doesnt lag? or any mapping techniques to seriously reduce it?

Are you using one single brush for the water, or many? Wave and transparency settings probably have the most significant effect, but I don't think you'll find much to change at the source code level. As far as the engine cares, water is just a special type of door:

LINK_ENTITY_TO_CLASS( func_water, CBaseDoor );

So take a look at the CBaseDoor (in doors.cpp) if you want to mess around with it, but to be honest I can't really think of much you could do that way. You'd have to define your own class and link func_water to it if you change a lot, since whatever you change will effect normal doors as well.
