Solved Setting player skin as server pic

That worked, I have a question.. I dont want to make a new post.. I want to make it so that the players avatar will be the server picture.. I want to do it so the players names arent in a hashmap so it will always be stored.. how would I do it with config? I have this:

Code:

            e.setMotd("§6Welcome!");

        }
    }
}

With this error:



Thanks for any help.. I can't figure it out :/
I get that error when I have never joined, and it says "Welcome back, null"

When I join it says "Welcome back, sgavster" and shows my picture.

 

@sgavster What is line 48 of drugs.java?

 

@sgavster i is null

 

@CodePlaysMinecraft I marked it with a note

@Skionz But I have checked if it's not :/ I can't figure it out

 

@sgavster Why do you have so much checks?

Code:

if(event.getAction() == Action.RIGHT_CLICK_AIR || event.getAction() == Action.RIGHT_CLICK_BLOCK){
            if(event.getMaterial() == Material.SOMETHING && event.getItem() != null))){
               
                //Stuff
               
            }   
        }
        

 

@sgavster It seems like you are checking if its type isn't null. Check if the ItemStack itself isn't null.

 

@sgavster Sorry, didn't see that, try checking if i equals Material.AIR

I get that error when I have never joined, and it says "Welcome back, null"

When I join it says "Welcome back, sgavster" and shows my picture.

 

bump, instead of making a new post I just changed the info and the title.

 

@sgavster Just create a new thread instead and set this one to solved by going to Thread Tools > Edit Title > Prefix > Solved.

 

@CodePlaysMinecraft Okay. I had made 2 posts the day I post this so I didn't want people to think I was spamming. I will do that.

 

@sgavster It's okay, as long as you don't post multiple threads of the same problem, you aren't spamming.

 

Moved to Alternatives Section.
