Use the same same instance

Hi

I wanna execute some sql query when a player joins and quits.
Now is my problem i can't use the instance who i made in the Main class.

Code:

public class CraftingTerritory extends JavaPlugin {
Logger log;
private GSMCommandExecutor mycExecutor;
public String logPrefix = "[CraftingTerritory] ";
public GSMMysql gsmMysql;
...
@Override
public void onEnable() {
...
/*Listener*/
getServer().getPluginManager().registerEvents(new GSMListener(), this);
 
.....
/*MySql*/
gsmMysql = new GSMMysql("localhost", "3306", "root", "", "gsm");
}
}

Now i wanna use the gsmMysql for my listener.

Code:

public class GSMListener implements Listener {
private CraftingTerritory plugin;
private funcs fu = new funcs();
@EventHandler(priority = EventPriority.HIGHEST)
    public void onPlayerJoin(PlayerJoinEvent e){
Player p = e.getPlayer();
 
if(plugin.gsmMysql.playerExists(p)){
plugin.gsmMysql.exStatemen("UPDATE spieler SET lastlogin_mc = '" + fu.getTime() + "' WHERE mcname = '" + p.getName() + "'");
}
 
    }
@EventHandler(priority = EventPriority.HIGHEST)
    public void onPlayerQuit(PlayerQuitEvent e){
Player p = e.getPlayer();
    }
}

 

Either make the methods static or send a instance of the main class to the subclass in the constructor

 

You mean this so?

Code:

private static CraftingTerritory plugin;

 

When you create GSMListener, are you assigning the plugin variable?

 

I don'tunderstand what you mean.

Here is the code if you need it.


Edit:
If i make a new instance of the GSMMysql class in the Listener class it works, but this way is very awkward.

 

add this to the listener

Code:

public GSMListener(CraftingTerritory plugin) {this.plugin = plugin;}

Change this in CraftingTerritory :

Code:

getServer().getPluginManager().registerEvents(new GSMListener(this), this);

This is what it looks like in my listener

Code:

public class CloneBlockListener implements Listener {
 
    private CloneMe plugin;
 
    public CloneBlockListener(CloneMe plugin) {this.plugin = plugin;}

 

Thx alot. This i alrdy tryd but i had:
private CraftingTerritory plugin;

i miss the static.

Thx.
