How do I make a strider, gunship, and hunter-chopper move on its own accord?

[Sweet in C]

I have been trying to use the gunship, strider, and hunter-chopper and have them move to the enemy, but they will either stay in one spot or go to a specific part of the map. Can someone please help?

The certain map requires air nodes in order, to have flying NPCs moving.
