How to make an object/NPC move freely?

Question

Unity

I am making a top view game. NPCs (let's take animals) that I have only go back and forth, like bobbleheads. How to make them move freely in a certain space, for example, a deer will sit in a clearing, and only in this clearing can move.

Answer 1

Guys, I immediately say I myself recently began to study Yunka and Sea Sharp.
In general, take a clearing for a deer. I would make triggers along the borders of the clearing that would give the deer a turn (random), that is, the deer is walking and then bam .. collided with the trigger, and the trigger turned it -+ by 65 degrees.

Answer 2

NavMesh can be used to move in 3D space. There are many different tutorials on YouTube on this topic. For example here .
And for 2D space, you need to do something of your own. Describe how to move with your hands. Look for this about moving Rigidbody2D.
