[Solved] Change the text of a redstonepowered sign

Hello, i want to get a sign powered by redstone to view the time, with the code i made the sign needs power directly, but i want to make it posible to change the text like this:
[sign][a random block]___[redstonetorch]
_____ = redstonedust

Code:

    public void onBlockRedstoneChange(BlockRedstoneEvent event){
        Block block;
        block = event.getBlock();

        if(block.getState() instanceof Sign){
            Sign sign = (Sign)block.getState();
            if(sign.getBlock().isBlockPowered()){
                if(sign.getLine(0).equalsIgnoreCase("Tiden er:")){
                    Date Dato = new Date();
                    SimpleDateFormat Tid;
                    Tid = new SimpleDateFormat("HH:mm:ss");
                    Tid.setTimeZone(TimeZone.getTimeZone("GMT+1"));
                    sign.setLine(1, ChatColor.DARK_BLUE + Tid.format(Dato));
                    sign.update();
                }
            }
        }
}

I personally don't know how to do what I am about to say, but I'm sure it's possible:

Check the block the sign is attached to if it is powered, I'm sure there is a method in the sign class to allow this to be possible (if not you could always do an area check)

 

ok, solved, not so tidy but works

Code:

    @Override
    public void onBlockRedstoneChange(BlockRedstoneEvent event){
        Block block;
        block = event.getBlock();
        if(block.isBlockIndirectlyPowered()){
            Location loc = block.getLocation().add(0, 0, 2);
            Block signblock = event.getBlock().getLocation().getWorld().getBlockAt(loc);
            if(signblock.getState() instanceof Sign){
                Sign sign = (Sign)signblock.getState();
                if(sign.getLine(0).equalsIgnoreCase("Tiden er:")){
                Date Dato = new Date();
                SimpleDateFormat Tid;
                Tid = new SimpleDateFormat("HH:mm:ss");
                Tid.setTimeZone(TimeZone.getTimeZone("GMT+1"));
                sign.setLine(1, ChatColor.DARK_BLUE + Tid.format(Dato));
                sign.update();
                }
            }
        }
        if(block.isBlockIndirectlyPowered()){
            Location loc = block.getLocation().add(0, 0, -2);
            Block signblock = event.getBlock().getLocation().getWorld().getBlockAt(loc);
            if(signblock.getState() instanceof Sign){
                Sign sign = (Sign)signblock.getState();
                if(sign.getLine(0).equalsIgnoreCase("Tiden er:")){
                Date Dato = new Date();
                SimpleDateFormat Tid;
                Tid = new SimpleDateFormat("HH:mm:ss");
                Tid.setTimeZone(TimeZone.getTimeZone("GMT+1"));
                sign.setLine(1, ChatColor.DARK_BLUE + Tid.format(Dato));
                sign.update();
                }
            }
        }
        if(block.isBlockIndirectlyPowered()){
            Location loc = block.getLocation().add(2, 0, 0);
            Block signblock = event.getBlock().getLocation().getWorld().getBlockAt(loc);
            if(signblock.getState() instanceof Sign){
                Sign sign = (Sign)signblock.getState();
                if(sign.getLine(0).equalsIgnoreCase("Tiden er:")){
                Date Dato = new Date();
                SimpleDateFormat Tid;
                Tid = new SimpleDateFormat("HH:mm:ss");
                Tid.setTimeZone(TimeZone.getTimeZone("GMT+1"));
                sign.setLine(1, ChatColor.DARK_BLUE + Tid.format(Dato));
                sign.update();
                }
            }
        }
        if(block.isBlockIndirectlyPowered()){
            Location loc = block.getLocation().add(-2, 0, 0);
            Block signblock = event.getBlock().getLocation().getWorld().getBlockAt(loc);
            if(signblock.getState() instanceof Sign){
                Sign sign = (Sign)signblock.getState();
                if(sign.getLine(0).equalsIgnoreCase("Tiden er:")){
                Date Dato = new Date();
                SimpleDateFormat Tid;
                Tid = new SimpleDateFormat("HH:mm:ss");
                Tid.setTimeZone(TimeZone.getTimeZone("GMT+1"));
                sign.setLine(1, ChatColor.DARK_BLUE + Tid.format(Dato));
                sign.update();
                }
            }
        }
        if(block.getState() instanceof Sign){
            Sign sign = (Sign)block.getState();
            if(sign.getBlock().isBlockPowered()){
                if(sign.getLine(0).equalsIgnoreCase("Tiden er:")){
                    Date Dato = new Date();
                    SimpleDateFormat Tid;
                    Tid = new SimpleDateFormat("HH:mm:ss");
                    Tid.setTimeZone(TimeZone.getTimeZone("GMT+1"));
                    sign.setLine(1, ChatColor.DARK_BLUE + Tid.format(Dato));
                    sign.update();
                }
            }
        }
    }

 

Auch.
Do you know about a "for" loop?
If so, you could just create a method like:

Code:

public static BlockFace[] directions = {BlockFace.NORTH, BlockFace.SOUTH, BlockFace.WEST, BlockFace.EAST} 

public static Sign findAttachedSign(Block baseBlock){
    for (BlockFace direction : directions){
        Block block = baseBlock.getRelative(direction);
        if (block.getState() instanceof Sign){
            Sign sign = (Sign) block.getState();
            if (sign.getLine(0).equalsIgnoreCase("Tiden er:")){
                return sign;
            }
        }
    }
    return null;
}

Then, just call this function to find the sign if the block is indirectly powered. It returns null if there's no attached sign with that format.
