Hello everybody. I am hellrogu3 and i really like wire mod. I don't know many things about it but im trying to learn. Here i will post a tutorial about how to make a amraam homing missile. The amraam is an addon that works with wire mod. It shoots missiles and you can make with it lots of "explosive" things:
Here comes the video:

Oh and there is something you don't see , i will explain it written :
- You have these things: The amraam , the beacon sensor , the constant value (1:0) , the target finder and the numpad input
- Wire the X , Y and Z of the Amraam Missile Launcher to the Beacon Sensor (For X select output world_x , for Y select output world_y and for Z select output world_z)
-Wire the Beacon Sensor to the Target Finder
-Wire the "Launch" option of the missile to the Numpad Input
-Wire the "Lock" option of the missile to the Target Finder
-Wire the "LockTime" option of the missile to the constant value.
And there you go!

You can download the amraam missile addon here: http://www.garrysmod.org/downloads/?a=view&id=11851
Something else: If you want to make it to don't seek for Players and seek for NPCs or Thrusters or Hoverballs just set the Target finder as you want and thats all.
