1. We will not support ancient versions. There is no reason to stay on older updates, as posted in this thread. We will provide help assuming you are on the newest version, but if it does not work on 1.7, then it is up to you to either update or figure it out yourself.
2. If you want to reply to this thread, after you already made a reply, click the edit button and add what you want to say. Do not double post.
3. We do not provide code here. We are here to help you solve your problem, not write your plugin for you.

Again, to achieve the '10 block grid distance', do the following:

1. Create a Location instance. This should be equal to the player's location.
2. Create a Vector. This is equal to the player's location's direction (player#getLocation().getDirection()). This is the direction the player is looking. Use the .normalize method so all numbers are between 0 and 1.
3. Create a for loop. This will loop up to 10, starting at 0.
4. Inside the loop, spawn a particle at the location. You can either use the World#spawnParticle method, or use one of the many utils already out there.
5. After that, add the vector to the location, using Location#add(Vector);.
