How to change the server icon?

Hey Bukkit,

I was wondering, how i can change the server icon, with a command or any trigger.

I do not have any code, but i don't know you i must get started.

Greeting,
Ronald

 

Just put a suitable image in the root directory of the server, I believe it must be a 64x64 px image in jpeg or png file format.

 

That's not what i want to have..

For example: I execute the command: /online, then changed the server icon to a 'Offline' icon

Maybe the loadServerIcon method?

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

There's no other way I believe. It must have a unique name, making it impossible to trigger.

 

I believe you can do that with ProtocolLib, but you can try loadServerIcon.

Edit:
Do this in a ServerListPingEvent

Code:java

File fileObject = new File("pathToSomeImage.png");
event.setServerIcon(Bukkit.loadServerIcon(fileObject));

(Should work, not sure tho)

 

Here, check my signatures plugin. I'll grab code snippets in a sec.

Code:

 
@EventHandler
    public void serverPing(ServerListPingEvent evt) {
      evt.setServerIcon(YOUR IMAGE HERE);
    }

Just have the 'YOUR IMAGE HERE' change when you execute your command.

Can this with a command?

 

DusRonald Yes.

• Create a field of type CachedServerIcon
• When you execute the command, it has to set that field to the icon you want to load (the CachedServerIcon loading has been posted in a previous post)
• When the ServerListPingEvent fires, you check if the field is null. If it is not null, you set the icon in the event to the one loaded in the field.

 

fireblast709 Maybe this?: (I don't have experience with ServerListPingEvent, and Server icons.

Code:java

File fileObject;
 
    @Override
    public boolean onCommand(CommandSender sender, Command command,
            String label, String[] args) {
        if (command.getName().equalsIgnoreCase("online")) {
            // TODO: Permission Check.
 
            File fileObject = new File("online.png");
            return true;
        }
        return false;
    }
 
    @EventHandler
    public void onServerListPing(ServerListPingEvent e)
            throws IllegalArgumentException, UnsupportedOperationException,
            Exception {
        if (fileObject != null) {
            e.setServerIcon(Bukkit.loadServerIcon(fileObject));
        }
 
    }

 

DusRonald Almost. fileObject on line one will always stay null because you never assign anything to it (line 9 will create a local File object instead of using the field). Just remove the 'File' from 'File fileObject' and you should be good to go.

Also, to boost performance a bit, I recommend you do the Bukkit.loadServerIcon in the onCommand (since file IO can be slow).

 

Yes, but you can i call the event?
Bytheway: Sorry for my very bad english, i'm dutch, and it's hard for me to understand english..

 

DusRonald why do you need to call the event?

 

Oh i understand the code right now, At the Event althrough..
fireblast709 Does this efficient work:

Code:java

File fileObject;
    public ServerState state;
 
    private enum ServerState {
        ONLINE, OFFLINE;
    }
 
    @Override
    public boolean onCommand(CommandSender sender, Command command,
            String label, String[] args) {
        if (command.getName().equalsIgnoreCase("online")) {
            // TODO: Permission Check.
 
            fileObject = new File("online.png");
            this.state = ServerState.ONLINE;
 
            return true;
        }
        return false;
    }
 
    @EventHandler
    public void onServerListPing(ServerListPingEvent e)
            throws IllegalArgumentException, UnsupportedOperationException,
            Exception {
        if (fileObject != null) {
            if(this.state == ServerState.ONLINE){
                e.setServerIcon((CachedServerIcon) new File("online.png"));
                setState(ServerState.ONLINE);
            } else {
                e.setServerIcon((CachedServerIcon) new File("offline.png"));
                setState(ServerState.OFFLINE);
            }
 
            //e.setServerIcon(Bukkit.loadServerIcon(fileObject));
        }
 
    }
 
    public void setState(ServerState state){
        this.state = state;
    }

 

DusRonald You seem to misunderstand what I meant.

Code:java

private CachedServerIcon icon;
...
this.icon = Bukkit.loadServerIcon(new File("online.png")); // Could be "offline.png"
...
if(this.icon != null)
{
    e.setServerIcon(this.icon);

 

Sorry for misunderstand, i try to understand, but sometimes and somethings......
