Um, I'm not sure I understand exactly where you're getting at, but NPC's do act upon collision with the player with an if (playertouchsme) {}. I've noticed that if you create an NPC and set it to move from point A to point B, and the player is standing somewhere inbetween the path, idle, then when the NPC goes through the player, the system reads it as if the player is touching the NPC, even though the player did not move at all.
