BTREE BIRD

The object of this example is to show how Artificial Intelligence can be applied to a videogame.

The Bird (enemy) has a patrol way, with differents "point checks" along him.

When the Bird reach a point check, stops a little time and continue to next point check.

Meanwhile, the player goes yellow if go near to the Bird, and red if closer.

When the player is yellow, the point checks of the patrol way begins to move to the player, and change the music. 

When the player is red, the bird looks at the player and shoot.

All of this is controlled thru a Behaviour Tree who decide all de bird actions.

The player goal is to resist max. time without die and total time in red color also.

Controls: Left/Right to rotate.  Up/Down to forward - backward.
