How to attach an IR grenade to a ammo box without script?

[BlackbirdSD 15]

New to the forum, played since Operation Flashpoint.

I want an ammo box to be placed in the jungle with a 100 placement radius(which I know how to do) and have an IR grenade or IR strobe of some sort, be attached to or follow the placement of the ammo box.  Im not into scripts yet so preferably in the Init field.  Currently I tried placing the ammo box and put the "IR module" next to it and synced it to the box.  This works and I see the IR Grenade but once I have a random placement of the ammo box, the IR grenade stays where it is and doesn't move to it.

 

Thanks

("O_IRStrobe" createVehicle position this) attachTo [this,[0,0,0]];

Put this on init field of the ammo box. If you want to adjust relative position of IR strobe and ammobox, adjust [0,0,0].

[BlackbirdSD 15]

That worked great!  So I did the same by adding the strobe to a player and it worked but in my mission I start off as a scuba diver parachuting using

this addBackpack "B_Parachute"; this setPos [getPos this select 0, getPos this select 1, 3000]

Now the strobe works in freefall but once the chute opens, the strobes get left behind and not sure why.  So I thought I will just add a backpack with the strobe, to be manually picked up from the inside the ammo box but how do I get that backpack (with the strobe Init command) inside the ammo crate?

Thank you

Because this is what happens to attached items when you enter a vehicle (in this case parachute)

[BlackbirdSD 15]

I just noticed that while getting in and out of a sub.  When I said that when the chute opens I lose the strobe, I found out that it only gets lost for the 2 AI parachuters but not me as the player.  when I land I still have the strobe but as soon as I enter my sub and get out, its gone.  Any suggestions?  Can the command line in the Init, be activated by a trigger or radio command to turn it back on after you exit the vehicle?

@BlackbirdSD,

You can paste this function and call into your init.sqf. When player is NOT in a vehicle (including parachute) they will have IFF strobe.

Spoiler

you_fnc_strobeIFF=
{	params [["_caller", player]];

if (alive _caller) exitWith {
	_obj = "NVG_TargetC" createVehicle [0,0,0]; _obj removeMagazine "B_IR_Grenade";
	_obj attachTo [_caller, [0,-0.03,0.07], "LeftShoulder"];
waitUntil {!isNull objectParent _caller || !alive _caller};
	deleteVehicle _obj;
waituntil {isNull objectParent _caller};
	[_caller] spawn you_fnc_strobeIFF;
	};
};

[player] spawn you_fnc_strobeIFF;

Will work with AI characters too.

Have fun!

Thanks for the reply.  I will need help with this.  I haven't done scripts before.

Works great for myself, haven't tried with human players but it doesn't seem to work with the playable AI

Do my players need to have a specified name?  "you_fnc_strobeIFF=" does this need to be left at "you"

I have 3 human players playing my mission.  Currently named p1,p2,p3

Thanks

[wogz187 1086]

@BlackbirdSD,

This is the call,

[player] spawn you_fnc_strobeIFF;

Anybody who calls the function gets the IR,

[anybody] spawn you_fnc_strobeIFF;

If it's MP it should probably be something like this,

[p1,p2,p3] remoteExec ["spawn you_fnc_strobeIFF"];

but I haven't figured out remoteExec yet so somebody may care to correct me.

Have fun!

1. What do you mean by "This is the call"?

2. Do I just add this "[p1,p2,p3] remoteExec ["spawn you_fnc_strobeIFF"];" at the end of the INIt file?

Thanks

The call to start the function. Just putting the function in the init doesn't begin it. In this case it's technically a "spawn" not a "call".

Try creating an "initPlayerLocal.sqf" file in your mission folder and pasting,
 

Spoiler

you_fnc_strobeIFF=
{	params [["_caller", player]];

if (alive _caller) exitWith {
	_obj = "NVG_TargetC" createVehicle [0,0,0]; _obj removeMagazine "B_IR_Grenade";
	_obj attachTo [_caller, [0,-0.03,0.07], "LeftShoulder"];
waitUntil {!isNull objectParent _caller || !alive _caller};
	deleteVehicle _obj;
waituntil {isNull objectParent _caller};
	[_caller] spawn you_fnc_strobeIFF;
	};
};

[player] spawn you_fnc_strobeIFF;

I created a file called InitPlayerLocal.sqf and pasted in the above.  I setup myself as player another ai in my group as playable and another ai outside my group as playable and only I had the strobe and not the others.

Good. Okay. So when other players fill those slots they will get IR, I think.

 

To make the two AI have IR-- in init.sqf,

[p2] spawn you_fnc_strobeIFF;
[p3] spawn you_fnc_strobeIFF;

That might be sufficient to get the other players blinking, too-- I really don't know.

I'm only scratching the surface of MP myself but now that I think about it you may need to use remoteExec to a) make everybody blink, and b) so everybody can actually see each other blinking. Which would be something like,

[p1,p2,p3] remoteExec ["spawn you_fnc_strobeIFF;"];

but I'm not sure.

Have fun!

[BlackbirdSD 15]

This worked for me and AI.  just need to test with friends but im sure it will be ok.

 

To make the two AI have IR-- in init.sqf,

[p2] spawn you_fnc_strobeIFF;

[p3] spawn you_fnc_strobeIFF;

 

Thanks a lot!

Is there a way to attach an IR strobe to the parachute vehicle once it's deployed?

Yes
 

player addEventHandler ["GetInMan", {
	params ["_unit", "_role", "_vehicle", "_turret"];
if (_vehicle isKindOf "B_Parachute") then
	{
		private _toAttach = "";//classname of strobe effect
		private _IRG = _toAttach createVehicle (position _vehicle); 
		_IRG attachto [_vehicle, [-0.2,0,0.6]];
	}; 
}];

 

[wogz187 1086]

An event handler is better for the removal of lights from dead units,

			{	IRLight = "NVG_TargetC" createVehicle [0,0,0];
				_x removeMagazine "B_IR_Grenade";
				IRLight attachTo [_x, [0,-0.03,0.07], "LeftShoulder"];
	_x addEventHandler ["Killed", {_lightID= _this select 0; {deleteVehicle _x;} forEach attachedObjects _lightID;}];
				} forEach units _grp;

Have fun!

[wogz187 1086]

Here's a more comprehensive solution,
(after a bit more testing I found the GetInMan EH only works about 70% of the time... investigating)

Spoiler

 

			{	private _IRLight = "NVG_TargetC" createVehicle [0,0,0];
				_IRLight attachTo [_x, [0,-0.03,0.07], "LeftShoulder"];
	_x addEventHandler ["Killed", {		{deleteVehicle _x} forEach attachedObjects _unit}];
	_x addEventHandler ["GetInMan", {	{deleteVehicle _x} forEach attachedObjects _vehicle}];
	_x addEventHandler ["GetOutMan", {	private _IRLight = "NVG_TargetC" createVehicle [0,0,0];
						_IRLight attachTo [_unit, [0,-0.03,0.07], "LeftShoulder"]}];
	
				} forEach units _grp;

Removes light when boarding vehicles and reapplies upon exit. Units removed by script will leave a light unless attached items are also removed.

 

Have fun!

[wogz187 1086]

Fixed it,

Spoiler

you_fnc_addIR=
{	params [["_grp", grpnull, [grpNull]]];
			{	private _IRLight = "NVG_TargetC" createVehicle [0,0,0];
				_x setVariable ["you_IRLight", _IRlight];
				_IRLight attachTo [_x, [0,-0.03,0.07], "LeftShoulder"];

_x addEventHandler ["Killed", {deleteVehicle ((_this select 0) getVariable ["YOU_IRlight", objNull])}];
_x addEventHandler ["GetInMan", {deleteVehicle ((_this select 0) getVariable ["YOU_IRlight", objNull])}];
_x addEventHandler ["GetOutMan", {private _IRLight = "NVG_TargetC" createVehicle [0,0,0];
					(_this select 0) setVariable ["you_IRLight", _IRlight];
					_IRLight attachTo [(_this select 0), [0,-0.03,0.07], "LeftShoulder"];}];
			} forEach units _grp;
};

Paste the function in init.sqf, a unit init, mission init field, etc.
Call example (unit init):

[group this] call you_fnc_addIR;

 

Or to do what OP asked for,

Spoiler

null= this spawn {
				private _IRLight = "NVG_TargetC" createVehicle [0,0,0];
				_this setVariable ["you_IRLight", _IRlight];
				_IRLight attachTo [_this, [0, 0, 0]];
};

right in the init dialog box of the object.

Have fun!

Guys, hi. Base on @wogz187 approch:

 

1) Create a file called "strobHuman.sqf" into your mission folder;

 

2) Put it in the file:
private _IRLight = "NVG_TargetC" createVehicle [0,0,0]; 
(_this select 0) setVariable ["you_IRLight", _IRlight]; 
_IRLight attachTo [(_this select 0), [-0.08,-0.35,0.1], "LeftShoulder"]; //attached on the unit backpack.

3) In each INIT unit, insert it:
null = [this] execVM "strobHuman.sqf";


OR

For ACE users, this is a simple solution that works with units, objects and vehicles without calculation of axis position:

Unique step) Just put it in each INIT object that you want to strobed:
[this, this, ["ACE_IR_Strobe_Item"],true] remoteExec ["ace_attach_fnc_attach"]; 
 

 

Both solution i have tested 😉

Cheers!

[wogz187 1086]

@thy_,

Using a script function allows us to skip creating a new .sqf file. Paste the function in init.sqf, in the init field of a unit, object, helper, or directly in the mission init dialog field.

Call the function any time with a single line,

// in a script
[_grp] call you_fnc_addIR;

or
// in a unit init field
[group this] call you_fnc_addIR;

This iterates through each unit in the group.

The event handlers are necessary. Otherwise units will leave their IR beacon behind when boarding vehicles or upon death.

To remove the lights,

{
	deleteVehicle (_x getVariable ["you_IRlight", objNull])
} forEach units _grp

Have fun!

@wogz187 and everyone, hello.

I've tried your solution and something is getting wrong here (but without error message):

 

 

1) In init.sqf file:

 

 

 

 

2) Then I've added the call into the group lead. When I ran it, there's no IR strobe on in-game, only darkness instead. 

 

 

No clue what is happening and some help where, will be very much appreciated. 

[wogz187 1086]

@thy_,

I checked by copying and pasting the script above (my post) into an open scenario and it worked as expected.

You can check by pasting the function into the unit's init along with the call. It does not have to be the leader of the group. Or call it on your player character from the debug menu!

Have fun!

Me too. Take a look in here:

Not sure what I'm doing wrong. If you put some light would be brilhant.

[thy_ 171]

Regarding the example (link above), any idea why that is not working as expected?
