I don't know how to play animations, i know how to make them though, how would i make it so that instead of doing the regular walking, the npc does a walking animation that i want it to do?
inside of the model put this script which will change the walking animation assuming you have animate in the model.
local npc = script.Parent npc.Animate.walk.WalkAnim.AnimationId = "rbxassetid://YOUR ID NUMBERS HERE"
that is seriously it ^^
if this helped please accept! ~KIHeros
