Defective collision sensor

How would i get the collision sensor to detect what i shoot at it?The object it is on physics type is sensor.Here’s the blend.Press c to shoot the bullet.

You are using dloc to move the bullet which technically teleports the bullet, I changed the blend file so that your bullet using linear velocity instead, now it works.

The property of shatter is not decreasing.Is it decreasing for you?

Sorry, this is the right blend… misread the question. You were sending the message to cube instead of enemy, and your sensor receiving the message was not hooked up.
