...use physics impulse?

I want my asteroids to get knocked back slightly when a bullet hits the and I already set the physics but it won't work. I tried it with asteroid on collision with bullet and I tried it the other way around and nothing seems to be working. How do I get this to work?

If you are using Physics behaviors for everything, make sure the mass of the bullet is higher than the asteroids.

The bullet doesn't have the physics behavior, only the asteroid.

You need to apply physics to the bullet as well. Physics will only interact physically with another object that has physics also applied to it.
