How do I make a barrel into a weapon crate

[donalexander 10]

Can someone please help me to make a barrel contain an ACE2 jerrycan so I can add it to my mission, I would like to be able to walk up to and and press GEAR to get a jerrycan out of a barrel to refuel vehicles in my mission.

Use ACE? :)

Actually, if you have ACE just make a script that checks if they have a launcher already, then gives them a jerrycan. Seems the jerrycan just "works" once you have it.

Well, making a invisable weapon holder in order to make a real gear menu might be a little to complicated i'll go with addaction and adding the jerrycan to the player.

put that in the init of the barrel

this setVariable ["ammount",2]; //change the ammount to the number of jerrycans you want
nul = this addAction ["Take Jerrycan", "jerrycan.sqf",[],0,false];

now make a jerrycan.sqf file and put this in.

private ["_caller","_type","_barrel","_ammount","_backpack"];
_barrel = _this select 0;
_caller  = _this select 1;

_ammount = _barrel getVariable "ammount"; //How many jerrucans are there
if (_ammount>0) then
 {
   _backpack = [_caller] call ACE_fnc_FindRuck;
   if (_caller hasWeapon _backpack ) then {_caller removeWeapon _backpack }; //Get rid of                               backpack if he has one
   sleep 0.3; 
   _caller addWeapon "ACE_JerryCan_Dummy_15"; //Add the Jerrycan
   _ammount = _ammount - 1;
   this setVariable ["ammount",_ammount ];
 } else 
   {
    hint "There are no more jerrycans in the barrel";
   }; 

You can limit the amount of jerrycan you want to give to the players by using a global variable and some if inside.

Thank you gman it worked perfectly I just had to change the barrel init to nul = this addAction ["Take Jerrycan", "jerrycan.sqf",[],0,false]; it didnt work the other way.

Just wondering how to put in a global variable? or how can I make it so there is just one or two jerrycans in there?

private ["_caller","_type","_barrel","_dummyTarget","_backpack", "_limit", "_avail"];
_barrel = _this select 0;
_caller  = _this select 1;

_limit = 2; //Max number of jerrycans available
_avail = _barrel getVariable ["TAG_jerrycans_available", _limit]; //Retrieve the current number of jerrycans available, if none were taken the variable does not exist, default to the limit
if (_avail > 0) then //Some are available
{
  _backpack = [_caller] call ACE_fnc_FindRuck;
  if (_caller hasWeapon _backpack) then
  {
      hint "You must drop your backpack first!";
  }
  else
  {
     _barrel setVariable ["TAG_jerrycans_available", _avail - 1, true]; //Save the number of jerrycans available now
     _caller addWeapon "ACE_JerryCan_Dummy_15"; //Add the Jerrycan
  };
}
else
{
  hint "No more jerrycans available.";
};

The code should be 100% MP safe thanks to the broadcasted setVariable. I also removed the automatic backpack removal. I think it's much better to let the player do it himself so he doesn't wonder where it's gone.
