The basic animal AI is finished, passive and aggressive behavior. It is a very basic ai, and of course some polishing needs to be done such as hit animations, sounds, hearding behavior.... For basic animals and testing this works great.
Also you can see how the spawning zones are set up, this is just a small one (the big cube with the dragon icon in it) for testing. The player walks inside of the zone, and animals are spawned randomly in location, as well as the number of animals spawned. The player can walk outside of the zone, and a timer will start for de spawning the animals. So if players are not around in the zone, animals, etc will be de spawned.
This is a great feature to save on performance.
Also, funny things happen when testing AI..... The wildebeest happened to run in between the player, and the rhino, so the rhino ended up killing both the wildebeest, and the player. Pretty silly stuff.
