I thought Small was a weak-typed language ?
Anyway, like I said, I don't know the AMX Mod X way of doing things at all, but provided there is a possibility to send and hook the same messages than in native code, it should be possible to send "fake" radio messages, and bots should be able to interpret them.
But like I said too, for the bots to interpret them correctly, they need to know the sender of the message, and the sender
of the message must be a valid player edict
. That's all
