Custom Creeper chrashes test client before it even starts
Fri, 11/02/2018 - 21:07

So I tried my best to create a custom creeper mob, and apparently everything is fine with the class itself however, if I try to start a client, a fatal error appears and I can't detect the reason of that error, but I know that the error comes from the Creeper Class. If someone can look what causes this major error and knows how to fix it, please reply!
