That line should save the last visible position of the bot, so he remembers for a while last enemy instead just forget him after 1 second or so. The problem is - the bots hsouldn't react on each noise every frame, becase it's inhuman. When You are hunting an enemy, You are remembering alos the last visible position of him and for some time You are trying to be more careful for that direction, no matter what You can hear around. For bots with lower than 100 skill, the aiming should be a bit scrambled (defined by AIM_OFFS_X,Y,Z) and updated every 1 second (higher frequency - the scrambling effect is annoying and inhuman). That line shouldn't affect the normal aiming for the bot with skill 100.
