Hello,

i am developing an android game with libgdx and box2d. I made a simple enemy that walks towards the player.

I can shoot bullets and move the bullets like this:

body.applyForce(m_impulse,body.getWorldCenter(),true); // This is applied only once

This moves the bullet straight forward, that is what I want. But when the ( small ) bullet hits an enemy, he gets thrown back like 100kilometers. How can i prevent that?

Physically speaking, see if you could change the enemy's mass.

Now speaking according to my personal experience with farsear for xna (which is based on box2d)
If I'm not mistaken you can override the collision event of the enemy. Just make sure you return false and it'll be like the collision never happened (though you could alter the enemy's life attribute and remove the bullet before returning false)

Excuse me for my english and grammar
