Alright, here is a plugin for anyone who wants it, it teleports a user to wherever the admin is pointing his cursor.
Usage: type /tele <user> or sm_tele <user> in console.
Warning: Users may get stuck in the wall if used whilst pointing at a wall. To resolve this, try to always point at the ground when teleporting someone.
Ok, I have updated this plugin. The formula I tried to use to limit the distance didn't work too well so the wall glitch still exists. However, I have now made the command more user-friendly and added particle effects for the teleport. The @all and @teams commands should be working, but for some unknown to me reason, they don't.
Enjoy!
