Since it is difficult to calculate the aiming position and aim direction by npc, it has been found that npc can shoot a target almost accurately (an exception when the player is in the almost north of npc 3.10~3.14 ) when the aiming position of npc is set exactly as the target position and aiming direction z co-ordinate set as -PI/2 if player is to the west ( of npc's position with N (north pole) taking into account. npc angle will be positive ) or PI/2 if player is to the east of npc ( the angle of bot will be negative ).|

{{Welcome| desc=This will send a packet to server which is filled by the following parameters.|

params=

( sniperid, aimposx, aimposy, aimposz, dx, dy, dz)

sniperid : The weapon ID of sniper (28 or 29) to fire.
aimposx : The x co-ordinate of aim position of NPC ( can be determined using server using player.AimPos or can be calculated artificially).
aimposy : The y co-ordinate of aim pos
aimposz : The z co-ordinate of aimpos
dx, dy, dz = The normalized direction vector(from aimpos to target ) multiplied by 16.
