Activate trigger is someone shot inside trigger area init

[muj Mobil 0]

Hello,

I would like to use Event Handlers for Fired but I am little lost.

 

I want create trigger area for example 10x10 m and if anyone, AI or player shoot inside that trigger it will activate code trigger. I do not really know what to write inside condition area.

flrObj = "F_40mm_white" createvehicle ((player) ModelToWorld [0,100,200]); flrObj setVelocity [0,0,-10];

Since the shot happens quite quickly, you will most likely have to add an event handler to the units, and not check the trigger state.

 

To get started, just put a trigger or create it in a script. Give it a name (variable name), for example, trg_1.

 

Then add a shot handler to all units that need it:

_units = allUnits; // As an example

{
	_x addEventHandler ["FiredMan", 
		{
			params ["_unit", "_weapon", "_muzzle", "_mode", "_ammo", "_magazine", "_projectile", "_vehicle"];
			
			// Here is your block called on every fired shot:
			
			if (_weapon in ["Throw","Put"] or !alive trg_1) exitWith {}; // Will not continue, if unit throws some grenade or put an explosive or trigger is deleted  
			
			if (_unit inArea trg_1) then 
				{
					// Here is your block called in case _unit fired while in area of trg_1
					
					call Your_script.sqf // As an example
					
					deleteVehicle trg_1; // If you do not need to call Your_script.sqf on every shot
				}
		}];
} forEach _units;

This handler will check at each shot whether the unit is inside the trigger trg_1, and if so, then run the script that you need.

So, if you need the script to run only once, and not from each shot in the trigger, that you need to delete the trigger at the first shot in it, as you can see it in the code.

So if anybody  fires a shot within a trigger area, you want that shot to cause the trigger to fire?

 

I don't know sorry.

 

You can start by finding out how to do it for yourself. That is, you walk into a trigger area, fire your weapon and that causes the trigger to fire.  Once you have learnt that, you can apply it to other soldiers on the map.

@Ibragim A already provided the answer.

...forget this top one I can't move it... just note the globals at the top which get called as a script off init.sqf... haveDamageBat... etc... its important...also notice how this is integrated with a firing drill... 

Spoiler

haveDamageBat = 0 ; 
hitObjIdsBat = [] ;
hitObjPosBat = [] ;

 



battle_guy addEventHandler ["Fired", { 
params ["_unit", "_weapon", "_muzzle", "_mode", "_ammo", "_magazine", "_projectile", "_gunner"]; 

[] execVM "battleShot.sqf" ;
	
}];

battle_guy addEventHandler ["Killed", {
	params ["_unit", "_killer", "_instigator", "_useEffects"];
	selectPlayer BIS_FD_Competitor ;
	[] execVM "init.sqf" ;
	
}];

 

Suppose there's a handler that goes off when I shoot...and when that handler is called... it runs some code, and also calls another script or file....

Spoiler

sleep 6 ;

_listObj = nearestObjects [ killBox, [], 150] ;
_hasDamage = 0 ;
{

	_damage = getDammage _x ;

	if( _damage == 1 ) then 
	{

		_hasDamage = 1 ; 
		
		_placeOfHit = getPos _x ;
		hitObjIds pushback (str _x ) ;
		hitObjPos pushback _placeOfHit  ;
		//_x setDamage [ 0 , false ] ;
		hitObjs pushback _x ;
		deleteVehicle _x ;

	}

} forEach _listObj ;


if( _hasDamage == 1 ) then 
{

haveDamage = 1 ; 
hint "theres some damage" ; 
sleep 2 ;
}

That's your puzzle... what is "killBox"... I look for triggers in my sqm... virtual object or trigger..... there's things inside

I'll post a vid in a sec... 

A look at the sqm and trigger going off in my sniper's range.... the trigger constantly repeats... checking for my haveDamage variable...

 

Spoiler

class Item41
		{
			dataType="Trigger";
			position[]={6875.5742,2.5,3466.1338};
			class Attributes
			{
				condition="haveDamage == 1 ";
				onActivation="[] execVM ""snipers.sqf"" ;";
				sizeA=222;
				sizeB=222;
				sizeC=12;
				repeatable=1;
			};
			id=139;
			type="EmptyDetector";
		};

 

in retrospect haveDamage... my variable... goes back to 0 on camera termination... the trigger starts the camera script if you can find it above

[ZaellixA 383]

I believe @Ibragim A has provided a nice solution. I would alter it just a bit to incorporate a small change. The changed version would look like (reusing the code provided by Ibragim A)

 

_units = allUnits; // As an example

{ // For each
	_x addEventHandler ["FiredMan", 
		{ // Event handler code 
			params ["_unit", "_weapon", "_muzzle", "_mode", "_ammo", "_magazine", "_projectile", "_vehicle"];
			
			// Here is your block called on every fired shot:
          
			// HERE I CHECK WHETHER THE TRIGGER IS "ALIVE" SEPARATELY
			if (!alive _trg_1) exitWith {_unit removeEventHandler [_thisEvent, _thisEventHandler]}; // If the trigger is not "alive" remove the event handler completely
			
			if (_weapon in ["Throw","Put"]) exitWith {}; // Will not continue, if unit throws some grenade or put an explosive or trigger is deleted  
			
			if (_unit inArea trg_1) then 
				{
					// Here is your block called in case _unit fired while in area of trg_1
					
					call Your_script.sqf // As an example
					
					deleteVehicle trg_1; // If you do not need to call Your_script.sqf on every shot
              
					// REMOVE THE EVENT HANDLER IF YOU DELETE THE TRIGGER
					_unit removeEventHandler [_thisEvent, _thisEventHandler];
				}
		}];
} forEach _units;

So, the actual change is that I remove the event handler if the trigger is deleted. I do that for the unit which calls the deletion of the trigger right after the deletion of the trigger, which of course should be deleted along with the deletion line if you don't intend to delete the trigger or do it in another place outside the event handler. For the rest of the units I added a separate check (Ibragim A was already checking for it in order to skip the event handler's execution, so I just moved the check into a separate check) on the top of the code to be executed by the event handler to test whether the trigger exists or not and if not the event handler terminates and its removal is called.

 

Of course, these changes are relevant (as well as Ibragim A's check for the status (alive/dead) of the trigger) if you intend to delete the trigger some time or make the code more generic.

 

I hope this provides an alternative, improvement or at least some insight.

 

Have fun with ArmA.

Although I understand that interacting with people can manytimes provide insights and instigate discussion and provide new solutions, I am not sure how helpful a comment like "I don't know" is... There's but a minuscule portion of the forum users who can say the opposite for the majority of the topics here. So, I believe that posting to say you don't know how to do something and/or you cannot provide the solution is not very helpful to the OP.

Be careful here if adding to remote units. Take note of the warning on the events page...

Quote

Special multiplayer behaviour: When added to a remote unit or vehicle, this EH will only fire if said entity is within range of the camera. That range is determined by the fired ammo's highest visibleFire and audibleFire config value. In case of units, muzzle attachment coefficients are applied too.

I did provide a first step. You probably missed it.

I note the OP has not returned. Most likely because he has not understood anything that has been said.

 

A new point:  Many activities in the editor have an easy solution. The editor is designed that way. Many have stopped playing the game because they were given a complex solution they did not understand.

 

Yet another point. When I have made the same comment before I have been told those other people were lazy.

"Figure it out for yourself" isn't a first step. And yes, not applying yourself is lazy.

 

The cognitive dissonance is just wonderful.

 

The OP already stated an interest in a scripted solution, so your suggestion of nothing was not helpful.

[ZaellixA 383]

I'll agree with @Harzach here. Encouraging someone to find a solution doesn't seem like a step (first or not) towards a solution. Nevertheless, I just wanted to make a point that, in my opinion, it would be quite instructive to post when we have something to add to the knowledge base of the community in some way.

Not much to be done about it, if this is the case. I am sure we've all seen people posting once or twice and then abandoning their question (for various reasons) and others that insisted "until the end" in an attempt to solve their problem at hand. All we can do is provide educated and well structured solutions and suggestions to the people here in order to increase the overall level in the community and help people.

I don't think (just my opinion though) that scripting and modding is necessarily, directly, related to playing the game. I had been playing ArmA for quite some time (about 5 to 6 years) prior to start scripting. I haven't really put much research effort in finding out if this is the case so it may be otherwise.
