Getting possition of smoke grenade

[Bashkire]

Well, simple question, I'm guessing not so simple answer. I want to enable the player to determine where a helo will land for extraction by throwing a smoke grenade and then the helo will land on or near its possition.

Is this possible and if it is, can someone let me know the code/script I'll need to write to do it?

Thanks.

Short form pseudo code:


-Event Handler fired
-Figure out what type of object was fired
if(smokegrenade) then getPos _this select X

Then you got it! questions? Ask!

You could use fired -eventhandler. Another way, if the extraction place is defined, to use nearobjects.

[Bashkire]

Right... erm, I've never used event handlers before. Care to give me a step by step guide?

Gonna write you an example when I got my arma running again.That's in about 2 hours.

Place the following to your init.sqf for example:

TAG_fired =
{
     _unit = _this select 0; //The unit that fired the weapon
     _wpn = _this select 1; //The weapon that was fired
     _muzzle = _this select 2; //The muzzle of the weapon that fired
     _ammo = _this select 4; //The ammunition type (classname) of the fired projectile

     if (_wpn == "Throw" && _muzzle == "SmokeShellMuzzle") then //A smoke grenade was thrown
     {
          _smoke = (getPos _unit) nearestObject _ammo; //Get the object
          if (!isNull _smoke) then //Make sure the above didn't fail
          {
               hint format ["The smoke grenade is: %1", _smoke];
               //Some addition handling, do not forget to spawn/execVM if you want to use sleep/waitUntil!
          };
     };
};
unit addEventHandler ["fired", {_this call TAG_fired}];

Thanks mate! I'll give it a go.

Doesn't it work with move an invisible H to the smoke?

[Tankbuster]

Perhaps I'm out of date, but I thought a thrown grenade didn't generate a fired EH?

[Bashkire]

Yeah, I'm not sure what I did wrong but the code didn't work.

Any other hints?
