bug where the player is looking

from the image, you can see that im trying to make something similar to a sonic boom appear when right clicked with an item, ti works, the part that dosen't however is the direction of the sonic boom itself, i also can't get it to make damage when it hits something. i tried inserting pretty much anything in "with vx, vy, vz," but it either desen't work or it makes the game straight up not load and it tells theres a but with the code, any ideas on how to fix it?
