/*
(c) Trooper 2009
This is the Filterscript "Maverick Gunner",originaly written by Trooper.
Please don`t miss my credits, i put a lot of work in it.
If you would do your own script, you would dislike this kind of people editing and sharing scripts like one of their own !

Information:
*You need to get in a Police Chopper
*You need a skin from Governmental Services (Skin ID 280 to 288)
*Use the arrows (to aim X & Y)
*Use the keys you would use for an hydra to start (for example) to in-/decrease height

//#################### Server Settings ##############################

// ---------------- Section Performance -----------------------------
new camtime = 100; //the time for refreshing the camera of the gunner
new rockettime = 200; //the time to check if the rocket is at the aiming spot
new keytime = 100; //the time to lookup pressed keys for gunners

// ---------------- Section Testing ---------------------------------
new testing = 0; //0 = off, 1 = on || testmodus meaning teleporting to an existing chopter + getting police skin to test this script (type /testing ingame)

// --------------- Section General Options --------------------------
new explosiontype = 6; //type of explosion, see wiki
new Float:explosionradius = 10.0; //radius of explosion, see wiki
new Float:rocketspeed = 56.0; //speed of the rocket to move

/* ---------------- Some Informations -------------------------------
1.Look at line 79/80 to change the Model of your raket (to see what model it is, use google or read the commentary at their back)
2.I used a lot of variables, i dont know anymore exactly, for what they are used ! You can delete unused Variables if you want to !
3.If your not good in scripting, just edit the values above (!!!)
4.If the message appears too often, that the Launcher is not ready, use /reload
5.Feel free to edit, but never miss out my credits in script & console-printout
