You are actually doing good, the sscanf and the clientmessages are fine. But you are NOt ACTUALLY IMPLEMENTING the action drag. Use getplayer pos of the cop and then set a timer every second to set the targets position X+2, Y+2 (X and Y are the cops position). You could do it differently, this is how I would do it though..if there's a better way, please share!
