You have to split your game to sessions and only work with NPC in the session where is at least one player. When working with NPC, test their set locattion (you have to set location for each NPC, like Place=wood) if it exist, simple every time when session is created add its name to array, when session dies, deletes. Then simply use If "sessionName"exist.

About animations, you can just convert it. If X1>X, then X+1 and set direction to Right. If <X, then X-1 and set direction to Left. If delta X is different than 0, set animation to Walking.
