For any mod team who want to combine NPCs and the Half-Life 2: deathmatch maps (which lack nodegraphs), may I recommend this pack. Created as described (by me - yay, go me!) in this article, enclosed are nodegraphs for all the built-in hl2dm maps. These should be considered to be completely freely redistributable.

My now only occasionally-updated attempt at a speech engine. With all the sounds spoken by yours truly. It excels at some words, and is terrible at others, and while one or two of the sounds need updating, i really just need to carefully time the 1600 or so possible combinations of consecutive syllables.

A patch file that updates the HL2MP version of the Orange Box Source SDK to have working NPC & monster AI. Uploaded for three reasons:

• Firstly, because it involved hundreds of fiddly little changes, but nothing actually clever, so is very time consuming to implement manually.
• Secondly, because a lot of people would seem to want to make Co-op mods, and this is an integral part of that. And although several people have clearly implemented AI successfully already, no one so far has made anything like this available. Sods!
• Lastly, because the developer.valvesoftware.com wiki upload feature won't accept anything but images!

Update: Now includes NPC lag compensation, which was missing in the previous version.
