JordyPwner Ensure that you are running the latest version of your code, and that your code matches the above.

 

What you mean?

 

JordyPwner Your stacktrace says that you're trying to add the player rather than their UUID

 

yeah so how will i fix it?

 

JordyPwner Firstly make sure that you don't try to add the player to the list

 

still dont understand

 

JordyPwner Your stacktrace is telling you that somewhere you're trying to do list.add(player) rather than list.add(player.getUniqueId())

 

well then u may tell me where cause on line 17 it says: Commands.donators.add(player.getUniqueId());

 

JordyPwner Exactly, that's why I said make sure that you're running the latest version of the code. I'd try re-exporting to see if that changes anything.

 

Still dont know the fix. BUMP

 

Show us the entire class and the new stack trace.

 

its still the same if u can read

 

JordyPwner No need to be an asshole. Your stack trace says you are trying to do something like this

Code:

ArrayList<UUID> list = new ArrayList<UUID>();
list.add(player);

instead of

Code:

ArrayList<UUID> list = new ArrayList<UUID>();
list.add(player.getUniqueId());

Show me the commands class.

 

I didnt mean to say it angry just saying that if have readed u have might know it that it is still the same also thx for the fix

Also where do u put: list.add(player);
:/ sorry

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

JordyPwner The stack trace says your trying to add a Player to a list of UUID's instead of a UUID to a list of UUID's

 

then it says list is not defined or something

 

post your commands class

 

It said: list cannot be resolved

change all of these

Code:

Commands.donators.add(player);

to

Code:

Commands.donators.add(player.getUniqueId());

 

then it says: Cannot make a static reference to the non-static field Commands.donators

 

Change it to static then

 

then it gives the UUID error back

this is the player class of now what i have when i decompile it:

JordyPwner Stop using static. You are using it wrong. Go learn about Passing Information to a Method or a Constructor.

 

MAYBE you should help me to get the right thing. and not post some links THAT I CANT UNDERSTAND cause its in english >.<

 

He is trying to help you, If you want help on this forum don't be an asshole to the people.

Anyway, to the fix (as many people have said in this thread before);

Code:

The method add(UUID) in the type List<UUID> is not applicable for the ar
guments (Player)

This says exactly what your problem is.

Code:java

 Commands.donators.add(player);

To

Code:java

 Commands.donators.add(player.getUniqueId());

The problem is you're trying to store the entire player where you should actually be storing his UUID.

 

What's wrong with English? It's the dominant language on this forum and you seem to read my posts just fine. Did you just TLDNR that link?

 

You know im not english but dutch? and only understand basic english not coding english :/

Thats why i have!
This is my current class

The error i have on the lines Commands.donators.add(player.getUniqueId());
is: "Cannot make a static reference to the non-static field Commands.donators"
so how will i fix that error?

JordyPwner
1: Learn java
2: put the word "static" in front of each of the arraylists.

EDIT: Make sure you put a space after the "static"

 

PHP:

Commands.list.remove(player);

Your IDE should have told you how to fix this, but anything that says "player" in your code (where you're doing anything with these lists) change it to "player.getUniqueId()"
