Now I'm getting an error when I click in the guardia egg idk what happens :/

 

ok here it is the error: http://prnt.sc/ebrsyz

 

@tigres810
The string is null for the replace method on line 109 of the onInteract method. The code you posted before is not the correct class or has been modified since you posted it. Just make sure that you nullcheck objects before you use them.

 

But the line 109 is a message and it works :/

 

@tigres810
What is the line where you use the "replace" method a string? Are you sure both the code and the error message are up to date?

 

Yes all works now I need to make a ArrayList and save players name when I click in the egg how I do it?
and I want that arraylist in the config if it's possible pls

Guys, how I do it. I can't if you don't help me :/

No all works just I need to make a arrayList and when I click the egg save the player name how I do it?

@tigres810
Do not double post. Wait 24 hours before bumping the thread.

Did you fix the error yet?

 

Yes it was in the config just change the int to 1 and it works fine but now I need to make the arrayList and when click the egg save the player name How I do it? sorry Im new in the page din't know :/

 

@tigres810
Do you want to create a new arraylist for each player, or have an arraylist that stores players?

 

I have this ArrayList: public static ArrayList<Player> jugadores = new ArrayList<Player>(); and when I store a player I do: jugadores.add(p); and jugadores.remove(p); but Idk if it saves when I reload the server or onenable it resets and how I choose all players in that list?

 

@tigres810

It does not. You will have to save the list to the config and reload it in the onEnable.

Also, do not store players inside of collections. This will cause memory leaks. Instead, store their UUID.

For loop through all the contents of the array. If you did what said above, after for looping through the UUIDs, use Bukkit.getPlayer(UUID) to get the player's instance.

 

How I save their UUID? Can you make me a code or something?

 

@tigres810

Code:

List<String> list = new ArrayList<>();
for(UUID uuid: YOU_LIST){
 list.add(uuid.toString());
}
getConfig().set("Path.to.uuids",list);

Use the above to save uuids. What it does is it converts each uuid to a string, put the string into a list, and saves the stringlist.

Code:

List<String> list = getConfig().get("Path.to.uuids");
for(String uuid: list){
 YOUR_LIST.add(UUID.fromString(uuid));
}

Use this to load the uuids. This gets the stringlist, loops through all the strings, and adds the UUID version of each string.

 

How I do this when I click the egg?

 

@tigres810
PlayerInteractEvent. Check if the item in the main hand is not null and that it is equal to an egg.

 

I get the next error when I added YOUR_LIST.add(UUID.fromString(uuid));
The method add(String) in the type List<String> is not applicable for the arguments (UUID)

 

@tigres810
That is because the list you provide is not the right list. You need to provide the one that stores UUIDs.
