Particle deflection

Hi everybody!

I was working in some animations and I couldn’t figure out how to get the particle deflection to work. My particles keep running through my walls! :< Does anybody has a tut about it, or can simply explain me how this thing works?

One more about particles: do they collide/interact to each other?

Think it’s all… Thanks

Right from the Blender site. It explains it all pretty well.
Don’t forget to do RecalcAll on your emitter mesh after changing deflection parameters (that may actually have been the problem).

And, no, particles do not interact with each other.

yet :-?%|

Thanks guy… The RecalcAll was the problem.
