So Ive been working on a Christmas Town full of fun games for those who play on my server. I spent a few days working on this epic snowball arena only to realize snowballs don't give knock back to players in vanilla minecraft! I was hoping with the addition of functions someone would have created one to give snowballs knock back in Vanilla minecraft but I have been unsuccessful in locating such a thing. So this is somewhat of a suggestion/request for those who have the knowledge and are able to write functions. I'm sure i'm not the only one who would love to have it!
