Create Block with Plugin

Hi guys,
maybe it's a silly question, but
1. how do I create a block or a wall in front of a player?
2. How do I create signs on which the is printed a String variable, that updates automatically?

1. If this is in a command executor, you need to cast the sender to a player first.
This code creates a wall in front of the player (if I used the getLineOfSight() correctly)

Code:

Location pLoc = player.getLocation();
List<Block> locs = player.getLineOfSight();
for (Block b : locs) {
if (b.getLocation().getY() == pLoc.getY() + 1) {
b.setType(Material.STONE);
}
}

2. You would use setLine()

Code:

Location loc = new Location(world, x, y, z);
Block b = loc.getBlock().setType(Material.WALL_SIGN) // or SIGN depending if it's on a wall or not
Sign s = (Sign) b.getState();
s.setLine(0, "First Line");
s.setLine(1, "Second Line");
s.setLine(2, "and so on...");
s.update();
}
}

When setting a sign's lines you need to update the state of the Sign.

thanks very much. I see what I can do...

But with this you need to look exactly the right way. Is there a way to just create a wall with an angle that I can set in my script?
