First babysteps coding. This bugged me when I was AI in 3 AI round. Now any number of AIs can use a single holopad. However, they cannot hear each other say things via holopad. I didn't want to dig into say code too much, some advice on that would be appreciated. Do let me know if there's poor code in here.
ah shit, i was supposed to say that you can't sign comments like that.
too late for that, i guess
