The Co-op Ping In Sp
Oh, it seems you can have a func_tank track pings with the new DLC! I suppose one could put a laser or tractor beam or paint sprayer or bridge or portalgun or something on it, and have it fire something.
Darn. I have R bound as "reload". Is there any way to change the SP ping key?

What would you be reloading in Portal?

Well I learned something today!

I think (but I'm not sure) that this was a new feature added to Co-op in the Peer Review DLC that accidentally made it into SP maps. With this feature, you can "ping" something with a thumbs up or a thumbs down symbol, so it might be to "Review" your partner (hence the name Peer Review).
I may be wrong though.
Is this feature still functional? I just attempted to use it and I got the menu to appear, but its stuck in the menu. Not even reloading the map will make the menu disappear and allow the player to walk again...
And I was hoping to incorporate this into a map... 
i noticed that some people who have made fairly advanced hammer maps utilized the teaching tool to teach players how to use what they added in their maps that are completely original, and due to an undesired effect, the tool got stuck on and was repetitiously reminding the players how to play the game in other maps
The game instructor hints? I don't know why, but if you play a map straight from Hammer (having it launch Portal 2 with $game_exe) and that variable is on it starts the tutorial over again from the beginning of the game. :S
is what i meant
