I think that whenever NPC-Server gets a PM, it should trigger "actionPM" to the control NPC, and in order to PM back, it would be something like
PM Faheria_GP2,Text;
so, some things could be added to the Control-NPC like
NPC Code:
if (actionPM) {
tokenize #p(0);
if (strequals(#p(0),Hello)) {
PM #p(1),Hi!;
}
}
In this example, #p(0) is the PM text, while #p(1) is the account of the player that sent it
I dunno if this is possible/practical or not, but it would be handy to have...
