Valve Developer Community talk:Community portal
Geogriffith: I am not entirely sure as to what should go here. But it seemed like a good place to list links to other sites that may be of use to developers.
Ideas: Create a standardized system to distinguish between sites that cater to HL1 and HL2 mapping.
Solo: I suggest that we make a more centralized table of contents per se... I'm currently scavaging around on the site finding random tidbits of information, but I still can't find what I'm looking for which happens to be how to create breakable glass in CS:S.
Geogriffith: Yeah, that sounds pretty good. This site is going to need a lot of cross referencing before it becomes useful. Oh, and Func_breakable is what you're looking for, btw. This is the HL1 guide, but the entity has the same name in source.
