Does anyone know of a super simple sample or tutorial that might get me started?
Many thanks in advance!
Have you already read Craig Reynold's website?
The general idea is linear algebra. Move you boids towards the center of mass. This can be done by using vector operations which is very affordable in simulation. If the linear algebra is the problem try reading up on it before. Other than that I would recommend to start looking at biods from the mathematical point of view first to not become confused with the indexes of vectors and stuff like that. If you understand the general mathematical principal the implementation is no problem.
