How do I stop a sprite from being knocked back when hit?

I want to stop my sprites from being knocked in the opposite direction when hit by a bullet. How do I do this? (For clarity, the bullets are destroyed when they hit anything.)

and the sprites that you want to stop geting nocked back are??? wich behaviours they use?? more info please

The sprites that are getting knocked back use the solid, physics, and 8-direction behaviors.

the bullet itself should not cause any kind of force...

can you paste the .capx file???

Should the bullets not be solid and/or not have physics?

Not normally a good idea to mix physics behaviour with anything else, it can lead to unexpected problems....
