Solved change the direction of a sign

Hi everyone,

I was wondering how I could create a sign that always "looks" at the player that created it with the tool I designed in my plugin.
You can enter the lines of the sign and then rightclick with a golden hoe to create lots of them.
However, I don't know how to get the direction from the player, invert it and give it back to the sign.
This is my code so far:

Code:java

 
Location loc = event.getClickedBlock().getLocation();
loc.add(0, 1, 0);
loc.getBlock().setType(Material.SIGN_POST);
Sign sign = (Sign)loc.getBlock().getState();

Thanks in advance.

Does anyone know how to change it into a direction like north, south, east, west at least?

Use this:
Where 3 is south, 2 is north, 5 is east, and 4 is west.

Code:java

 sign.setRawData((byte) 3);

 

Code:

    public byte getDirection(Player player){
          double rotation = (player.getLocation().getYaw() - 90) % 360;
            if (rotation < 0) {
                rotation += 360.0;
            }
            if (0 <= rotation && rotation < 22.5) {
                return 0xC; //S > E
            } else if (22.5 <= rotation && rotation < 67.5) {
                return 0xE; //SW > SE
            } else if (67.5 <= rotation && rotation < 112.5) {
                return 0x0; //W > E
            } else if (112.5 <= rotation && rotation < 157.5) {
                return 0x2; //NW > SW
            } else if (157.5 <= rotation && rotation < 202.5) {
                return 0x4; //N > W
            } else if (202.5 <= rotation && rotation < 247.5) {
                return 0x6; //NE > NW
            } else if (247.5 <= rotation && rotation < 292.5) {
                return 0x8; //E > N
            } else if (292.5 <= rotation && rotation < 337.5) {
                return 0xA; //SE > NE
            } else if (337.5 <= rotation && rotation < 360.0) {
                return 0xC; //S > E
            } else {
                return null;
            }
        }

You can modify this to your needs.

 

I get something like 0x2 now, but how do I make the sign go into that direction?
