}
@EventHandler
public void event(PlayerJoinEvent event) {
Player player = event.getPlayer();
// create a new scoreboard with title
SimpleScoreboard scoreboard = new SimpleScoreboard("§a§lGamersPlay:");
// text with custom score
scoreboard.add("§lTestinam", 1337);
// also supports blank lines (up to 23 of them!)
scoreboard.blankLine();
scoreboard.add("§cTestuojam");

// if you dont specify a score it will display them in the order you add them in
scoreboard.add("testas");
scoreboard.add("§bin");
scoreboard.add("§edescending");
scoreboard.add("§2order");
scoreboard.add(":) lol");
scoreboard.blankLine();
// the text can be up to 48 characters long (including color codes)
scoreboard.add("bla bla bla §l48 :eek:");
// call this to create the scoreboard, nothing will happen if you forget to call this
scoreboard.build();
// send the scoreboard to the player(s), takes an array
scoreboard.send(player);
player.sendMessage("testinam");
}
public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args){
Player player = (Player) sender;
if(cmd.getName().equalsIgnoreCase("rangas")){
if(player.hasPermission("extra.narys")) {

pleasse help me to fix this :/

 

Register. Events.

 

zDylann
Can you help me to do that?

 

Hsas4849

in your onEnable() {

type

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

and of course, if the the events class is your main class, just put this.

 

ZodiacTheories
What to do if i don't have an Event's class?

 

Hsas4849

What do you mean, which class did you type @EventHandler ?

 

ZodiacTheories
in main class ( GamersPlay )

 

Really? No @EventHandler?

 

Hsas4849

Well then type getServer().getPluginManager().registerEvents(this, this); under getLogger().info("GAMERSPLAY IJUNGTAS");

 

TGRHavoc
look up, i edited the post ( mistake sorry ), so how i can fix this :? pleasse help me

 

Hsas4849

i told you

 

ZodiacTheories
still dosen't shows the Scoreboard :/

 

Hsas4849

Stack-Trace?

Also, show me where you typed it please.

 

ZodiacTheories
I typed it here:

Code:java

public void onEnable(){
getLogger().info("GAMERSPLAY IJUNGTAS!");
getServer().getPluginManager().registerEvents(this, this);
}

 

Hsas4849

Stack trace?

 

ZodiacTheories
What you mean whith "Stack trace?" ( if i translate to Lithuania it i get "footprint" )

 

Hsas4849
"Stack Trace" is the error that you get in the console when something in the code goes wrong.

 

Oh okey :

Code:
