Solved Preventing Snowballs From Knocking Items Out of Frames

Hello! I have a plugin that uses snowballs as projectile weapons. the only problem is that they can knock items out of item frames, witch is not a very good thing when you have item frames everywhere in your main spawn area.

Is there a way to prevent them from knocking the items out of frames?

I tried canceling the HangingBreakByEntityEvent, however this did not stop the item from being knocked out or from me destroying the frame. upon further investigation i discovered i could only break the frame if i threw the snowball by hand (I spawn the snowballs upon right clicking a item). any help/advice would be nice, thank you!

 

Thanks! this worked.
