A hitbox is a representation of the hit detection system used by the Counter-Strike series and many other games. Different boxes represent the different areas of the body, such as the head, which influence the damage of a shot. Hitboxes can be displayed using the server command sv_showhitboxes. However, due to the complexities of the networking code, this does not accurately represent how hits are actually determined, particularly in CS:Source where the networking code is more complex. This has caused many complaints by players who do not understand the system and for this reason, more recent versions of the Source engine have disabled the sv_showhitboxes command.
