Well yes that thread has quite a bit of neat information but unfortunately it deals more with ai_relationships and console commands. Looking through it I couldn't find anything about info_nodes or scripted sequences...
I'm deeply confused how example .vmf maps that have everything set up...
I want to do some work with crows on a level I'm working on and so have been attempting to learn how to use info_node_hint/info_node (experimenting with ground npcs and the air version of the nodes for the crows) and have had no luck what-so-ever.
In addition, I've tried scripted sequences...
