The Behavior tree in unity-tracking

In the game, in order to make the enemy more intelligent or "IQ" higher, we introduced the concept of behavior tree, what is the behavior tree? The simple understanding is that the other side will act in response to each other's actions when one is acting, as if it were a tree, and when the trunk moved, the branches and leaves would move accordingly. Now we apply its theory to our game and use it to track players, first of all we want to clear the target: the following:

You see, with the arrow is the target point, 22 is based on the target point of movement to take corresponding behavioral tracking. Let's show you a few more pictures:

Different moving positions, each other's boats make corresponding changes.

Next we implement the code, first we need to know whether the target is within our traceability range:

Next we need to determine how to track.

Finally, the following function is implemented to move to the target point.

I am here simply to explain to you, if the real implementation of a lot of things to do. The above is the tracking behavior tree, that is, when the player is moving, the enemy will be based on the player's direction to make corresponding judgments.
