Rigidbody collision

I have added a wall of cubes, I have added a rigidbody component to them so that I can shoot them and they will fall. But the bullet, wich is another cube, sometimes passes the wall without doing any damage. I look like it only makes the cubes move if the bullet hits the center of the cube. How can I fix this?

You can try the game for yourself and see the problem http://www.kongregate.com/games/xKripz/cube-murder

Thank you.

try scaling the colliders in cubes of wall and bullet.

You have to set the Collision Detection for RigiBody of bullet to Continuous Dynamic.

I fixed the problem. The box collider was 0,1,1.
