So, hi. I was thinking just now, and I had an idea, for which the title is perhaps a little misrepresentative. There is an entity that can detect pings in co-op, seen in the calibration course, right? Well, why couldn't that be utilised for a single player map? I know, there's no ping tool in SP, but the little hack would be that the player ss_maps the map, and then just shows one screen (the other player would probably have to be trapped in a box somewhere so that no alternate puzzle solutions could be found). So, do you think this could work? I can't actually think of any good puzzles that use this idea yet, but I think there could be a few... My main concern is that the average player doesn't even mess around with custom maps, let alone bother reading new instruction to play it, and so they might get confused. Thoughts?

Well, what would the player use Ping for? Maybe activate stuff? I don't know.

I am looking into an similar option (that would probably accomplish the same kind of things), trying to figure out a way to intercept portal gun particles to have objects that can respond to it abnormally. If anyone has any tips on this, they would be appreciated.
Thank You,
