Group Behaviour

• So far, we have largely talked about single objects, or a moving and a stationary object.
• However, it can be really cool to have agents work together.
• This is like A-Life, and involves emergent behaviour.
• Emergent behaviour means that simple actions by simple agents, together yield complex behaviour.
• In the context of movement, simple behaviours of agents (e.g. a bird), can lead to complex behaviours of groups of agents (a flock).
• Of course, the game developer can cheat, and decide on all behaviours simultaneously, so all the agents move exactly the same in a flock.
• This can even be a nice computational short cut.
