How to make How to make playable units invincible to friendly AI fire?

I'm having a problem here with a mission and the AI, specially the "friendly" AI. More than once they'll disregard the fact that you're in front of them when they engage the enemy. I've tried an eventhandler script but it seems to only work on non-playable units. Haven't been able to find anything all day, so here's what I've got so far:

EH_NoTK = {
   _source = _this select 3;
   if (side _source == EAST) then 
   {
   _this
   }
   else
   {
   0
   };
};  

and this is the unit's init line:

this addEventHandler ["HandleDamage", {_this call EH_NoTK}];

Any help would be very appreciated since most of the time in this mission you get killed by fratricide and I really suck at scripting.

Thanks in advance.

Try this code (if east side units are enemy):

EH_NoTK = {
_source = _this select 3;

if ((side _source) == east) then {_this select 2} else {false};
};

Try this code (if east side units are enemy):

EH_NoTK = {
_source = _this select 3;

if ((side _source) == east) then {_this select 2} else {false};
};

Nope, same as always, as long as it's the player or a playable unit it has no effect whatsoever.

Appreciate it, nonetheless.

Any solution, please?

Should work in theory. (untested)

unit addEventHandler ["HandleDamage",
{
if (side (_this select 3) != side (_this select 0)) then //if not the same side then set damage
{
	(_this select 0) setDamage ((damage (_this select 0)) - (_this select 2));
};

0;
}];

unit addEventHandler ["HandleDamage",
{
if (side (_this select 3) != side (_this select 0)) then //if not the same side then set damage
{
	(_this select 0) setDamage ((damage (_this select 0)) - (_this select 2));
};

0;
}];

Thanks man, will try it right away.

No luck.

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

Integrated into your function:

// this addEventHandler ["HandleDamage", {_this call EH_NoTK}];

EH_NoTK = {
_unit = _this select 0;
   _source = _this select 3;
   if ((side _unit) == (side _source)) then {
	false;
   };
};  

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

Still doesn't seem to work.

Hmm. Well it works in the editor for Arma3. The arguments the EH provides and the way it works hasn't changed at any point in time. I don't have Arma2 installed atm to get down to the brass tacks. I'm not sure what to say =(. Good luck.

Maybe your trying to use player variable to add the EH to the player object, before the player variable has been initialized on the clients machine :confused:

waitUntil (!isNull player && {time > 0}};
player addEventHandler ["HandleDamage",{
   if (side (_this select 0) == side (_this select 3)) then {
       false;
   };
}];

It's alright man, I'm just glad people are taking their time to help me out. As for the code, how should I integrate that one into my mission, exactly?

init.sqf

if (!isDedicated) then {
waitUntil (!isNull player && {time > 0}};
player addEventHandler ["HandleDamage",{
	if (side (_this select 0) == side (_this select 3)) then {
		false;
	};
}];  
};

init.sqf

if (!isDedicated) then {
waitUntil (!isNull player && {time > 0}};
player addEventHandler ["HandleDamage",{
	if (side (_this select 0) == side (_this select 3)) then {
		false;
	};
}];  
};

Nothing, seems unsolvable. By the way, I should mention that this is for an SP mission, although I plan on making it MP once this is fixed.

Is there really no way to do it?

Try this:

if (!isDedicated) then 
{
waitUntil {!isNull player && time > 0};
player addEventHandler ["HandleDamage",{if (side (_this select 0) == side (_this select 3)) then {false;};}];
};

tested it in SP editor with a radio trigger call.

I think it had to do with the curly braces v. round braces v. no braces in certain places.

Ahh yes good spot on the one typo (wrong bracket) before the waitUntil. It's still nice to use lazy evaluation though. So...

if (!isDedicated) then {
waitUntil {!isNull player && {time > 0}};
player addEventHandler ["HandleDamage",{
	if (side (_this select 0) == side (_this select 3)) then {
		false;
	};
}];  
};

Oh I saw it too now. Tested it, but it seems that now nothing can kill me.

How about this?

if (!isDedicated) then 
{
   waitUntil {!isNull player && (time > 0)};
   player addEventHandler 
["HandleDamage",
	{
		_damage = _this select 2;
		if (side (_this select 0) == side (_this select 3)) then 
		{
			_damage = 0;
		};
		_damage;
	}
];  
};  

Works for me in A2 editor if you just use the following in a units init field:

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

Test by placing two units on map, both same side, then one of the opposing side.

Oh panther it works! Thanks man! And everyone who supported the cause thank you too.

Sincerely, much appreciated.
