Editing Signs

Hi everyone!

I want to edit the text of a sign.
Basicly I have the coords and the world of a sign in a HashMap.

So now I want to check if the block at that coords is a sign and then write something on it.
Can I also check whether the row is at an end?

Please Help!

First get the block and it's state

Code:

Block block = world.getBlockAt(x, y, z);
BlockState state = block.gteState();

Then to see if it's a sign

Code:

if (state instanceof Sign){
    Sign sign = (Sign) state;
}

You then have sign.getLines() which will get all 4 lines and sign.getLine(int) which will get a specific lines, there are also corresponding set*() methods

Is the "world" in

Code:

Block block = world.getBlockAt(x, y, z);

the worldname?

No that would just be a string :? It's the world object.

I saved only the Worldname into the hashmap can I use that too?

You can get the world from that

Code:

World world = Bukkit.getServer().getWorld(worldName);

Thanks alot I test it.

So another problem occures.

I thought my code is correct so I tested it. But When I use the command to set the Line of a sign it didnt work! There was nothing to see onto the sign but there is also no error in the console or something like that.

Here the code:

Code:

public boolean ExecuteCmd(Player p, String cmd, String[] args) {
if (cmd.equalsIgnoreCase("set")){
StringBuilder news = new StringBuilder();
for(int i = 1; i < args.length; i++)
            {
                if(i > 1)
                    news.append(" ");
                news.append(args[i]);
            }
String newschecked = news.toString();
if (newschecked == null) {
p.sendMessage("Aufschrift kann nicht leer sein!");
p.sendMessage("Korrekte Verwendung: /signnews set [Aufschrift]");
} else if (newschecked != null) {
 
String SignName = "Sign";
int length = 4;
for (int i = 0; length < plugin.signs.get(SignName).length; i++) {
SignName = "Sign" + i;
}
 
String[] SignArguments = {plugin.signs.get(SignName)[0], plugin.signs.get(SignName)[1], plugin.signs.get(SignName)[2], plugin.signs.get(SignName)[3], newschecked};
plugin.signs.put(SignName, SignArguments);
 
//Koordinaten aus der Hashmap
int x = new Double(SignArguments[0]).intValue();
int y = new Double(SignArguments[1]).intValue();
int z = new Double(SignArguments[2]).intValue();
 
//Weltname aus der Hashmap in eine Welt umwanden
World world = Bukkit.getServer().getWorld(plugin.signs.get(SignName)[3]);
 
//Auf Sign überprüfen
Block b = world.getBlockAt(x, y, z);
BlockState state = b.getState();
 
if (state instanceof Sign) {
Sign sign = (Sign) state;
sign.setLine(2, newschecked);
p.sendMessage("Schild erfolgreich beschriftet!");
 
} else {
p.sendMessage("Der Block ist kein Schild!");
}
}
return true;
}
return false;
}

I dont know what to do.

Please Help!

Does nobody know why that doesnt work???

you never updating the sign whit BlockState.update();
yes, you using a block state inside you code
