Playing with maps !

Hi !
I'm trying to use the Map API of bukkit.
I'm testing something : I want that if I write something like /revealmap, all the transparent blocks in the map are changed to what they should look like.
How do I do this ? I found no tutorial about it

Thanks

I can't figure out how I can reveal the map... This should be easy !

Code:java

public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args) {
        if (commandLabel.equalsIgnoreCase("map")) {
            if (sender.hasPermission("itsn3wMap.base") || sender.isOp()) {
                if (!(sender instanceof Player)) {
                    sender.sendMessage(HEADER + "In Game only command");
                    return false;
                } else {
                    Player player = (Player) sender;
                    if (player.getItemInHand().getType().equals(Material.MAP)) {
                        MapView map = getServer().getMap(player.getItemInHand().getDurability());
                        map.setCenterX((int) player.getLocation().getX());
                        map.setCenterZ((int) player.getLocation().getZ());
                        map.setScale(Scale.FARTHEST);
                        /*
                            Reveal the map here !
                        //*/
                        player.sendMap(map);
                        return true;
                    } else {
                        player.sendMessage("No map held");
                        return false;
                    }
                }
            } else {
                sender.sendMessage(HEADER + "No permission !");
                return false;
            }
        } else {
            return false;
        }
    }

Ok so this is just impossible.

You need to write your own MapRenderer wich populates the map. The map is just a canvas where you can draw on. It's not a prerenderd map with just some "fog of war" over it. It redraws the blocks when you move.

PS: I had a lot of trouble figuring the map out. PM me if you need a kick-start.
