Line of sight problems

When I use player.getLineOfSight(null, 12) it returns the block the player is standing in and all blocks inbetween that block and the targetblock.
I want all blocks. I don't want the line to stop at the targetblock, I want it to stop at the number I define (12).

I would greatly appreciate any help I can get

 

As the Bukkit API says:

getLineOfSight

List<Block> getLineOfSight(HashSet<Byte> transparent, int maxDistance)
Gets all blocks along the player's line of sight List iterates from player's position to target inclusive

Parameters:
transparent - HashSet containing all transparent block IDs. If set to null only air is considered transparent.
maxDistance - This is the maximum distance to scan. This may be further limited by the server, but never to less than 100 blocks.
Returns:
List containing all blocks along the player's line of sight

By default, the HashSet only contains AIR, so it will stop if something that isnt air is in the way. Set the HashSet, so that it will not stop when it hits something else.

 

You can use a BlockIterator with getLineOfSight to get the wanted result.
