Updating lobby signs

Hi everyone,

I am trying to create plugin, that will update Lobby signs, but I don't know how. I googled and tried everything, but it doesn't work. I saved X,Y,Z,World of the sign to the config, but I can't make loop, that will change text on every sign in that list. For example, I want to put text "Test" to last line. But I can't make a loop, that will work.
If you want more info, just ask me.

Thank you!

 

@ano95 Get the block at that location, get the state, cast it to Sign (after checking), edit the sign, update the sign.

 

I know, but I want lopp, that will do it for every registred sign

Also, my actual code:

Code:

public static void updateSigns(Plugin mainplug){
        List<String> signs = mainplug.getConfig().getStringList("hubsigns");
        for(String sign : signs)
        {
           World w = Bukkit.getWorld(mainplug.getConfig().getString("hubsigns."+sign+".world", "world"));
           if(w == null)
               continue;
           int x,y,z;
           x = mainplug.getConfig().getInt("hubsigns."+sign+".x");
           y = mainplug.getConfig().getInt("hubsigns."+sign+".y");
           z = mainplug.getConfig().getInt("hubsigns."+sign+".z");
           Block b = w.getBlockAt(x, y, z);
           if(b.getState() instanceof Sign){
               Sign tsign = (Sign) b.getState();
               tsign.setLine(3, ChatColor.GREEN+"Online");
               tsign.update();
           }
        }
    }

Config file:

Code:

hubsigns:
  test:
    x: 15
    y: 100
    z: 3
    world: hub

FIXED: The hubsigns are not List Thank you, Skionz

1) If you fixed it, put solved
2) Heres a quick tip for saving multiple signs
Use UUID.getRandom().toString() to get a random number every time. This is if you are going to have an unspecified number of signs. If every time your gonna name the sign, you don't need this.

 

@ano95 Just gotta say. you need to cancel the event when the chunk where the signs are in gets unloaded.
