[Tutorial] Stop signs from being destroyed and the surrounding blocks

I'm making a new plugin and did this to stop signs from being destroyed and the surrounding blocks, so I decided to share it.

(Don't know why there's the colour tags)

Code:java

[COLOR=#000000] @EventHandler[/COLOR]
[COLOR=#000000]    public void blockSignBreak(BlockBreakEvent event) {
        if(event.getBlock().getState() instanceof Sign) {
            Sign sign = (Sign) event.getBlock().getState();
            // Stop the destruction of signs all together, if they contain stuff on each line
            if(sign.getLine(0).contains("VARIABLE")) {
                // if(sign.getLine(LINE).equalsIgnoreCase(anotherString)) {
                /* 
                 * Sign lines:
                 * 0 = First line
                 * 1 = Second line
                 * 2 = Third line
                 * 3 = Forth line
                 */                
                event.setCancelled(true);
            }
        }
 
        // Stop the blocks the signs are touching from being destroyed
        // We use 68 as the ID because the sign is a 'Wall Sign'
        if(event.getBlock().getRelative(BlockFace.NORTH, 1).getTypeId() == 68) {
            Sign sign = (Sign) event.getBlock().getRelative(BlockFace.NORTH, 1).getState();
            if(sign.getLine(0).contains("VARIABLE")) {
                event.setCancelled(true);
            }
        }
        if(event.getBlock().getRelative(BlockFace.EAST, 1).getTypeId() == 68) {
            Sign sign = (Sign) event.getBlock().getRelative(BlockFace.EAST, 1).getState();
            if(sign.getLine(0).contains("VARIABLE")) {
                event.setCancelled(true);
            }
        }
        if(event.getBlock().getRelative(BlockFace.SOUTH, 1).getTypeId() == 68) {
            Sign sign = (Sign) event.getBlock().getRelative(BlockFace.SOUTH, 1).getState();
            if(sign.getLine(0).contains("VARIABLE")) {
                event.setCancelled(true);
            }
        }
        if(event.getBlock().getRelative(BlockFace.WEST, 1).getTypeId() == 68) {
            Sign sign = (Sign) event.getBlock().getRelative(BlockFace.WEST, 1).getState();
            if(sign.getLine(0).contains("VARIABLE")) {
                event.setCancelled(true);
            }
        }
        // We use 63 as the ID because this sign isn't placed on a wall, so it's a 'Sign Post'
        if(event.getBlock().getRelative(BlockFace.UP, 1).getTypeId() == 63) {
            Sign sign = (Sign) event.getBlock().getRelative(BlockFace.UP, 1).getState();
            if(sign.getLine(0).contains("VARIABLE")) {
                event.setCancelled(true);
            }
        } [/COLOR]
[COLOR=#000000] }[/COLOR]

P.S If there's a better way of doing this, either leave a comment or fork the gist...

 

Just use a for loop and add to the location...
