Please help me understand Boids / Blender 2.5

Lancer · June 21, 2010, 12:57am

Does anyone have info on getting boids to work on blender 2.5? I’m following the tutorial for earlier Blender at…

http://feeblemind.org/blog/index.php?post/2007/12/28/106-setting-a-prey-predator-relationship-using-boids-particles

…but it’s confusing. About the stage where I’m supposed to put in the logic for Goal / Crowd / Collision / Avoid etc I lose it because I can’t find these values. Attempting other friend / foe relationships does not seem to work either.

Anyone please point me to somewhere I can wise up on 2.5 boids?

I would like to make…

Predator / Prey swarm
Mass crowd run over hilly terrain.

Thanks to anyone who can help.

I am lurking right over your shoulder!

One of mfoxdoggs videos included a demo of using boids in 2.5. Have a look at his site to pick out which one.

Among the several videos I’ve actually looked at, two ended up having particles, but I saw no boids:

http://mfoxdogg.com/2_5_tour9_physics.ogg had lots of particle experiments (and blender crashes) but I didn’t see boids
http://mfoxdogg.com/2_5_tour_10.ogg has bouncey particles, but again no boids.

I’m still lost on the things. This video is the best I’ve found; http://www.youtube.com/watch?v=ih_ZMhS8WzU but the resolution is so bad it’s almost a poor joke.
The manual page (http://wiki.blender.org/index.php/Doc:2.5/Manual/Physics/Particles/Particle_physics) lists properties of boids butI’m confused by all the spherical fields and stuff… would like a really simple example of predator chase, and/or how to make a boid army run over a hilly landscape if some one would be so kind.

Have you popped over to Jahka’s blog?

Richard, thanks for narrowing that one down… I saw boids at the end and it’s hopefully just in time to be useful for my current project. Odd that I found (and picked for review) one called tour 9, but did not see “tour 9 part 5”.

Atom thanks also. I understand the proper name for the particle system is “Jahka Particles”… are they named after the owner of that blog?
