[Solved] Once again, I need help. How do you make it so when they login it will do something

I need help on the script were if someone goes on the server it will do something, I know how to make it do something but I need to know how to make it so if they login it will please post.

 

Code:

@EventHandler
public void onPlayerLogin(PlayerLoginEvent event)
{
  //What ever here
}

 

You'd need to register PlayerLoginEvent in onEnable() then do what kumpelblase2 said in the class <plugin name>PlayerListener.

 

What you said is the old event system.

Code:

public class YourListener implements Listener
{
  @EventHandler
  public void playerLogin(PlayerLoginEvent event)
  {
 
  }
}

Code:

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

done.

 

And were shall i put that?.... In my main or make another class?

 

in my second post the first code part is a separate class for you listener where you can add more events if you'd like to. The second part is the registration of the listener which goes into your onEnable().

 

getServer().getPluginManager().registerEvents(this, this); in your onEnable and
the other one after your onEnable

 

Ah ok thx for your help i will try that out .

 

I've tried the above steps, and it's not working for me D:.

Here is the basics of my code, and the rrors:

Code:

public class blacklistcheckogin implements Listener {
    blacklist plugin;
 
    @EventHandler
 
    public void onPlayerLogin(PlayerLoginEvent event)
    {
    //stuff in here :)
    }
}
//Code in the onEnable() in my main class...
@Override onEnable() {
    blacklist plugin;
    getServer().getPluginManager().registerEvents(new blacklistcheckogin(), plugin);
 
}
 
//And finally all the wonderful erros...

Might be a long shot but is your class really named "blacklistcheckogin"?

 

looks like it is.

'plugin' is empty.

 

I tried using this as a second param, still threw an exception.

And yes, my class name is blacklistchecklogin, but that in no way would throw any sort of exception. .
By the way, I do want to mention that I have done a lot of debugging (I would say around a good day or 2) and I just can't figure it out, even after looking @ the bukkit javadocs, and a lot of other resources. I'm hoping that once the new event system is a little bit more ironed out, there will be more resources on it.

Looks like you're having an issue that I'm having, registerEvents() can't be found in PluginManager. Is this a bug in Bukkit 1.1-R4? (@kumpelblase2)

 

Its not a bug R4 works for me this is what i use Below

Code:java

 
    @Override
  public void onEnable()
  {
    registerEvents();
}
 

Code:java

 
  public void registerEvents() {
    PluginManager pm = getServer().getPluginManager();
    pm.registerEvents(new ExampleListener(), this);
    log.info("[Example] Events registered");
 
    }
}

Doesn't work for me, I'm getting an "The method registerEvents(ElderTrollsListener, Main) is undefined for the type PluginManager" from eclipse and a stack trace from CraftBukkit.

Does ElderTrollsListener implement Listener?

 

try doing /version at the server,a nd post the result, so we can see its version

 

It's registerEvent and not registerEvents.

 

uhhmmmm... no, not really.
http://jd.bukkit.org/doxygen/d1/dff...anager.html#a7e74e25e0c6bbc6ef23429f912c44163

 

It does, yes.

Server version? Erm, running CraftBukkit 1.1-R4, not sure how this is relevant to a compilation issue.

 

what version are you compiling against?
if it's an older version then "The method registerEvents(listener, plugin) is undefined for the type PluginManager"
meaning that the method "registerEvents(Listener, Plugin)" does not exsist in the PluginManager

 

Update your Bukkit.
The method is registerEvents, not registerEvent Pandemoneus

 

I am still used to the old event system.
But registerEvent does still exist.

 

Yes, but for the purpose of their discussion that's not applicable

 

mayby you compiling whit r4, but your server are running an onlder version, because you forgot to chence r3 to r4 at the start up script, whit /version we can see

 

Erm, what? I am using Bukkit R4 and CraftBukkit R4.

 

what version of r4?

 

Recommended on both.

 

what build nummer, because I also use that function at the recommend build whitout problems

 

nvm, it fixed itself.
