There are different ways to achieve this - if you want to do this only using ORK, you'll have to set up your NPCs to be combatants and use the move AI:
- the NPC's combatant should be an ally of the player (and potentially also of all other factions), so setting up an NPC faction that's friendly with every other faction might be a good idea
- use an Add Combatant component to add the combatant to your NPC game object in the scene
- if you want to use waypoints for the NPC to follow, you can add them in the Add Combatant component
- make sure the used combatant is set up to use a move AI
As for the animations, they'd be set up in the animation settings the combatant uses, similar to how it was explained in the game tutorial series. Since you only have idle and walk animations, you only need to set up those :)
The move AI doesn't actually move the game object around, it just tells the used movement component (e.g. a NavMesh agent) where to go. ORK's built-in default movement component is pretty dumb and just moves the game object toward the position, so I'd recommend setting up NavMesh in your scenes and using agents for movement.
