A processing game that demonstrates herd behaviour. Game can be accessed at https://harshjn.github.io/P5jsGame-EggVsSperm/
Every element of the flock (also known as vehicle) has a predefined target (egg in this case), but it is able to observe only a narrow neighbourhood around it. Therefore, it makes decisions about which direction it wants to move in based on the following factors:
- Whether it can find the target in it's neighbourhood (seek the target).
- What direction other vehicles around it are moving in (follow the herd).
- Avoid collision with other members.
Based on these factors, it calculates a force to locomote with. Force on the vehicle will be more closer to a target. With more motivation, it will move faster, but the maximum speed will be limited because of environmental constraints.
Herd formation or cluster formation is observed because of each vehicle wanting to do what others want within it's neighborhood. This appears a cohesive force between vehicles. Without this behaviour, no clusters will be formed.
