Most efficent way to store players in a lobby.

I am currently developing a minigame plugin for a server. I am currently using hashmaps to store players in a lobby. Example below.

Code:java

public HashMap<Player, Integer> hub = new HashMap<Player, Integer>();

Is theyre a better way of doing this or am I on the right track.

 

DividedByZero
Should store the Player's name instead of the Player object.

 

Hi, i have send you a message on skype, can you please answer. I have rtyed to get you in a long time

 

You can use ArrayList, it is better and faster. I don´t think you need to store Integers

Code:java

ArrayList<Player> hub = new ArrayList<Player>();

 

Ok i have this error I cannot solve!!! I dont know how to fix this.

Code:

This is my error


And this is my listener class.

Code:java

public class QuickRushListener extends JavaPlugin implements Listener {
    private Plugin plugin;
    public QuickRushListener(Plugin plugin) {
        this.plugin = plugin;
    }
 
    QuickRushVars vars = new QuickRushVars();
 
    @EventHandler
    public void onPlayerInteract(PlayerInteractEvent event) {
        Player player = event.getPlayer();
        boolean tempInHub = false;
 
        //Check if InHub
        if(vars.inHub.get(player)) {
            tempInHub = true;
        }
 
        //Check NetherStar InHub
 
        if(player.getItemInHand().getType() == Material.NETHER_STAR && tempInHub == true) {
            player.sendMessage("YES");
        }
        //End Check NetherStar InHub
 
        //Restore all values
        tempInHub = false;
    }
}

 

What's line 30?

 

there is none. it has something to do with
vars.inHub.get(player) == true


btw inHub is a hashmap that store a boolean

HashMap<Player, Boolean> inHub = new HashMap<Player, Boolean>();

Problem solved. I did vars.inHub(player) == dklfsdf
instead of .equals();
derp.

Why are you even storing the players?
