ToWarsDz nói:

Phần fix :
public class Main extends JavaPlugin {

public static Main main;

@Override
public void onEnable() {
main = this; <====================== thêm phần nữa này
registerEvent();
}

@Override
public void onDisable() {

}

public void registerEvent() {
PluginManager pm = Bukkit.getPluginManager();
pm.registerEvents(new PlayerChat(), this);
}

}

Trần Hữu An nói:

Thay vì dùng Main.main thì có thể dùng this để đỡ tốn thời gian hơn :)
