This can be handled several ways. But the simplest is to use a version of the above function in the Root text (first line) of the NPC. Place this script in the "Actions Taken" script handle on the first line of the NPCs conversation. Note: you must remove the nw_walk_wp script from the "End Conversation Normally" script handle found in the "Current File" Tab or the NPC will stand up at the end of the conversation.
