this is my main class :

and this is my register team class :

and this is my inventoryclickevent class :

@nightwolf111
Inventory click: this.main = new main();
You can't re-init your plugin, call it in a class constructor.
Also please use proper-naming conventions. Don't use main as a class name, name it the name of your plugin. also for packages, me.<name>.<pluginname> !

I found some errors in this code that can bring problems to you:

- You are checking an ItemStack in this line:

Code:

if(itemclicked == new ItemStack(Material.EMERALD_BLOCK,1)

it is wrong because ItemStack is an object and you need to use method .equals(anotherObject) instead of "==".

- You need to show where is the line of the errors to me find where is wrong and help you.

- You are not in accordance with the name conventions, it difficults to understand your code.

 

i changed the name of main to Game and i made a new class called Scoreboards :

this is the new Game Class :

and this is the new InventoryClick class :

and if needed that's the register teams class :

i tried what you said but it gives me errors too :

help me plzzz

 

Please read the following link:

The reason you are getting this error is because something is null on line 24 of the RegisterTeams class. Figure out what is null, and set that variable equal to something.

 

well, if iknow how to fix it i wouldn't post this thread i am a beginner in java coding i need some help the line 24 is : scoreboard.registerNewTeam(name); i don't know what's the problem can you help me pls ?

If you are a beginner of Java, then you should not be working on Bukkit plugins just yet. Although you may want to do bukkit first or may even want to learn Java while making plugins, you need to know Java before working on Bukkit plugins. The reason why is so you don't have to make simple mistakes like this one. Knowing the language you are writing in will help you both understand what you are doing (and make your programs more efficient) and will prevent you from making mistakes that should be avoided (making the time to create a plugin much shorter). Please, if you have not learned Java just yet, pick a tutorial from the following link and learn Java before returning to Bukkit.

The issue is that you're getting an NPE, which means a value on that line is not set to anything (null) and you are trying to make it do something . There are only two variables on that line: scoreboard and name. One of those to variables has to be null. What you need to do is check which variable is null and figure out why it is null. Once you do that, you need to make sure it is not null.

 

Why do that when you can just do

Code:

if (itemClicked.getType() == Material.EMERALD_BLOCK);

 

i am not totally begginer i learned the basics of java and i learned some buckets but i wanted to create a plugin to learn more, i know i always make mistakes like those x) i'll try to find out what is the problem. thanx anyways for helping me .

i can not use that it says it must be an ItemStack

 

@nightwolf111
Notice how it says

Code:

itemClicked.getType()

and not just

Code:

itemClicked

 

aah x) ok i did it


i solved the problem, i added a method in my main class wich is the game class to add new teams, and i called onEnable method thanx guys for your supports
