Nice mega bump guys, but really this does need to be stickied like a mother forgeter!!!
Edit: Just tested this in my server, it works.
findclientbyname(yournamehere).setcontrolobject(findclientbyname(victim));
Makes whoever's name you put in the first parentheses control the person in the victim parentheses
localClientConnection.setControlObject(findclientbyname(victim));
Makes you control whoever is in the victim parentheses
Note: The victim gets very, very weird images on their screen / their screen freezes up until they ctrl k, admin orb out, or leave.
findclientbyname(victim).crash();
Is it that hard? Makes the person the victim parentheses have a popup saying blockland has encountered a problem and needs to close, sorry for the inconvenience.
