Initiate chat by npc
by unknown posted previously in scripting
I couldn't get Pavel's script to work for me for some reason
this one does though.

void main(){
object oNPC = GetObjectByTag("put_npc_tag_here");
object oPC = GetEnteringObject();
if(GetIsPC(oPC) &&
IsInConversation(oNPC) == FALSE &&
GetObjectSeen(oPC,oNPC))
{
AssignCommand(oPC, ClearAllActions());
AssignCommand(oNPC, ClearAllActions());
AssignCommand(oNPC, ActionMoveToObject(oPC));
AssignCommand(oNPC, ActionStartConversation(oPC));
}
}

The DM needs to login to a new module so he can't use the
mod transition.
