My NBTTagCompound isn't working with SMP. It will edit everyone's properties.

Also the player chat message only sends to the last person to log in.

 

Attatching my mod project files to use for reference. It's a lot of code to post on here and would be better understood if ran on server and opened with eclipse.

Mmmmm~  Static properties. <3

Obviously sarcasm, and obviously a solution/alternative way of doing this. Care to inform or "Support" instead of that sarcasm that doesn't really help anyone. I'm trying to learn, Don't bring me up to your level.

You have static properties.

private static EntityPlayer player;
private static int miningXP;

 

If you don't know why I'm telling you this, you don't have a basic grasp of Java (or any programming language, to be blunt) and that is a base requirement of getting help on this board:

 

Modder Support

 

This is the support section for those modding with Forge. Help with modding goes in here, however, please keep in mind that this is not a Java school. You are expected to have basic knowledge of Java before posting here.

I do know java, quite well actually and I do know what static means and why youd say that. The issue wasnt that I didnt know, the issue was the rude reply, true better than none, but could have been done nicer without sarcasm.

 

Btw, from what I do know of java, static is only 1 instance or things like variables and methods can be used without instantiating.

 

And thank you for replying again even though I myself was a little rude as well.

The reason I get a little sarcastic is because people using static for inherently not-static purposes has happened four times in the last two days and several more times in the past.  90% of the time people don't understand what I mean when I say "why are you using static here?" because they don't know what they're doing.

 

And rather than try and supply copy-paste solutions, I'm forcing people to think.  Doing so means they learn things, even if it makes me look like an asshole.

 

It also means I don't have to do as much work to get a better result.

 

And I'm all about efficiency.  And I don't care what people think about me.

Well I do appreciate your help. I dont ask for code, but I honestly thought you were talking about the register and get methods being static, never even noticed the variables were static. And because you helped point it out, I noticed and that wws the solution. Thank you for all your help! =o)

Hence "static properties" not "static methods" and quoting the two in question.

The whole class is a custom property, and the register method is the only new initialization of it. So I thought thats what you meant by static properties, and ive never heard anyone call variables properties. But now that this is solved I shall lock it cause it's just spam now.
