Creating Fire At Crosshair

Okay so I've got a plugin and I was planning on adding fire at a radius configurable from my config.yml, the fire would either be created where the player's cross hair was or around a player of choice. So such as /FSmite [Player].
Here is the code I have so far.

Code:

       if(commandLabel.equalsIgnoreCase("fsmite")&&player.hasPermission("smite.fsmite")) {
            if(args.length == 0)  {
                Block targetblock = player.getTargetBlock(null,  100);
                Location location = targetblock.getLocation();
                player.sendMessage(ChatColor.GRAY + "Lightning with fire at Crosshair");
                world.strikeLightning(location);  
            } else if (args.length == 1) {
                if(player.getServer().getPlayer(args[0]) != null) {
                    Player targetplayer = player.getServer().getPlayer(args[0]);
                    Location location = targetplayer.getLocation();
                    world.strikeLightning(location);
                    
                    
                    player.sendMessage(ChatColor.GRAY + "Creating lightning with fire at " + targetplayer.getDisplayName());
                } else {
                    player.sendMessage(ChatColor.RED + "Error: That player is offline.");
                }
            } else if (args.length > 1) {
                player.sendMessage(ChatColor.RED + "Error: Too many arguements!");
            }
            return false;
    }

Any help at all would be very appreciated. Thanks!

All of what you need is in your code?

 

no I don't not know what code to use for creating a radius of fire above the ground around the player or at crosshair

 

Use the mathematical formula for a circle: x^2+y^2 = r^2

Code:java

// Get the origin of your circle (your players x and z)
                int ox = p.getLocation().getBlockX();
                int oz = p.getLocation().getBlockX();
                // define radius yourself
                int radius = 10;
                double radiusSquared = Math.pow(radius, 2);
                for(int x = 0; x <= radius;x++)
                {
                    for(int z = 0; z <= radius; z++)
                    {
                        if(Math.pow(x,2)+Math.pow(z, 2) <= radiusSquared)
                        {
                            Block b = p.getWorld().getHighestBlockAt(ox+x, oz+z);
                            Block up = b.getRelative(BlockFace.UP, 1);
                            up.setType(Material.FIRE);
                        }
                    }
                }
