Npc monster walkSpd

[submissive]

Hello all, I have some question about NPC moves. I would like that my npc (monster), don't move until I attack him. I can do this : can_move = 1, walkspd = 1, runspd = 180 for exemple (For what I understood, walkspd is when is not under attack, and runspd when attacked) With that configuration, when npc is not attacked, I see them legs move (like when he's walking) but he don't really move. I would like to have the npc legs don't moving. Is there any way to do this ? If I put can_move = 0, then when I attack him, he don't move, and if i put walkspd = 0, my client crash when i see the npc.
