Stumbled on this page in the Valve Developer Wiki (http://developer.valvesoftware.com) today.

http://www.lduke.com/mapping/hl2_entities_byentity.php

Basically it's a list of all HL2 entities, and for each just which HL2 maps use them. So if you are wondering how to use an ENV_FIRESENSOR, this page will tell youy that there is one in d1_town_01_d and d2_prison_05_d. Decompile the maps and then open them up in Hammer to see how it's used.

This will be a big help.. Thanks!

thank you.

Very useful, thanks

now it might be a dumb question, but how might one go about figuring out where some of the entities are used? like i know it says what map, but it doesn't exactly show where in the map its used. some are fairly self explanatory but others i'm not quite sure where i'd look to see it.

In hammer:

Map menu -> Entity Report... -> locate item and dbl. click it in the list, it will take you right to it.
