Handle damage from friendly side

[redarmy 420]

Greetings guys

 

Im trying to figure out a way through Handle damage to make it so that friendly units in my squad do no damage when the shoot me.Its for SP and in this instance i the player have no vest,no revive system and no respawn.

 

Its a persistent mission made across Altis with saving enabled however its basically one shot one kill with the way i have equipped units including myself.Play testing has made me realise that my own AI are more of a threat to me than zombies or enemy.

 

Does anyone know the correct command to enter in the player init to disable friendly fire to return the damage to 0?

 

I took a look at it but cant make much sense from it all but can tell its possible to achieve.

 

Many thanks

Hi redarmy

 

The way I'd do it would be to add a "hitpart" eventhandler to the player. Off the top of my head something like:

player addEventHandler ["Hitpart",

{

_unit = _this select 0;

_shooter = _this select 1;

if (side _shooter == side _unit) then

{

_unit setdamage 0;

};

}];

I'm on my work lunchbreak so can't verify that this works. The drawback is that if you are already damaged then being hit by a friendly will return you to full health. I'm sure you or others can finesse this further

Hitpart won't work, because it may run after the damage is already dealt. A headshot will probably kill the unit.

So use handleDamage instead.

 

This might work:

player addEventHandler ["HandleDamage",
{
_unit = _this select 0;
_damage = _this select 2;
_shooter = _this select 3;
if (side _shooter == side _unit) then { _damage = 0};
_damage
}];

@Greenfist I wasn't sure if handledamage _this select 3 was the shooter, or the actual object that caused the damage. At any rate we've given redarmy a few options to try :)

Thanks guys i got it working.I can crack on with making the mission now.

 

Appreciate it!

I'm shortly going to try the version above, since the difference is that you're aiming for player-only.

 

I also realized the dangers of trusting the AI's trigger finger, and in my case, the AI racked up more deaths from friendly fire than from enemy action. So I made my whole squad proof against friendly fire.

 

I got this one from jshock at:

https://forums.bistudio.com/topic/167406-how-to-allow-friendly-fire/

 

Put it in the init.sqf

{

if (side _x isEqualTo WEST) then

{
_x addEventHandler
[
"HandleDamage",

{

_returnDamage = (_this select 2);
if ((side (_this select 0)) isEqualTo (side (_this select 3))) then
{
_returnDamage = 0;
};
_returnDamage;
}
];
};
} forEach allUnits;

I modified it for my squad only:

waitUntil {!isNull player};

{
    _x addEventHandler
    [
        "HandleDamage",
        {
            _returnDamage = (_this select 2);
            if ((side (_this select 0)) isEqualTo (side (_this select 3))) then
            {
                _returnDamage = 0;
            };
            _returnDamage;
        }
    ];
} forEach units group player;

I know you already solved it, but I'm still learning, and it can be helpful to see multiple ways to phrase the same thing.

The two lads above helped me sort it but Jshocks script is actually a touch better as i now see the nessecity in protecting all AI on my side(who uncach in bis function task patrol,safe FILE formation) enemy appear at their front and its always a disaster for the front squad members.

 

Thanks for sharing

hi everyone and sry for digging this old thread, but i have a question related to this and dident want to create a new thread:

 

why does this not work?

edit: for landvehicles

{
	if ((side _x) == west) then {_x addEventHandler ["HandleDamage",{ 
		_unit = _this select 0; 
		_damage = _this select 2; 
		_shooter = _this select 3; 
		if (side _shooter != side _unit) then {_unit setDammage (0.2 + getDammage _unit)} else {_damage = 0}; 
		_damage 
		}];
	};
}foreach allunits;

so i want to disable AI friendly fire from same side and if not from same side then increase damage when hit.

thank you for this information.

{  
  	if (_x isKindOf "Car") then {  
   			_x addEventHandler ["HandleDamage", {   
     			_unit = _this select 0;    
     			_damage = _this select 2;    
     			_shooter = _this select 3;    
     			if (side _shooter == east) then {_unit setDammage (0.2 + getDammage _unit)} else {_damage = 0};  
		_damage   
   		}];  
 	};  
}

- Your last code can't work as is. _x has no sense here without   forEach vehicles (as example)

- where are you running your code?

thank you for that info 😃

i got it working now but is it possible to also include the vehicle-crew?

im using this vehicle and the crew is exposed and still takes friendly damage.

how would i combine vehicle and crew?

like this?

{  
  	if (_x isKindOf "Car" OR _x isKindOf "Man") then {  
   			_x addEventHandler ["HandleDamage", {   
     			_unit = _this select 0;    
     			_damage = _this select 2;    
     			_shooter = _this select 3;    
     			if (side _shooter == east) then {_unit setDammage (0.2 + getDammage _unit)} else {_damage = 0};  
		_damage   
   		}];  
 	};  
}  //what would i write here?
