force applied to rigidbody

[bisciasia]

hi to all.
i have a problem in my game.
i have 2 models of zombie with a rigidbody attached.
one zombie stay in one point waiting for that i go near him, other zombie walk in random way.
my problem is that when zombie that is in movement collides with not moving zombie, this start to move because has received a force during collision.
is there the way for keep stopped this zombie?
thanks a lot

Yes you can set the RigidBodies constraints. Tick the constrain boxes to constrain x,y and z. You can also stop rotation in the same way.
