Handle Damage before it's processed

[farooqaaa 2]

According to Arma 2 Wiki the player event "HandleDamage" should process the damage returned from that event but it's not working in Arma 3 and damage is handled by the engine no matter what this event returns.

Example code:

player addEventHandler ["HandleDamage", { _damage = 0; _damage; }];

I know that I can set allowDamage to false to stop the player from taking damage but that's not what I want to do. I want to customize the damage before it is processed.

Can anyone help? How does Arma 3 handle this event?

Thanks

When returning a value, you can't have a semi colon.

player addEventHandler ["HandleDamage", { _damage = 0; _damage }];

fixed.

Thanks for the fast response. I did that but still no luck.

This doesn't make the player invincible:

player addEventHandler ["HandleDamage", { 0 }];

And this doesn't make it die instantly after taking any amount of damage:

player addEventHandler ["HandleDamage", { 1 }];

Wrong area to post this. Try troubleshooting.

Mods will move this.

Yeah, I dunno why that's not working.

Try this:

player addEventHandler ["HandleDamage", {player setDamage 0;}];

EDIT:

Using this code on an AI unit named AI_unit will make him invincible.

AI_unit addEventHandler ["HandleDamage", {}];

Using the same code on a player does not make the player invincible.

Pretty sure the HandleDamage event is just broken right now.

if (!Isdedicated) then {

waitUntil {!isNull player};

player addEventHandler ["HandleDamage", {_damage = _this select 2; _unit setdamage _damage;}];

};

A few notes: It gets executed 5 times, for each selection ("head_hit", "torso", "legs", "arms" and ""). Using the example code above will give you undesired behavior most likely.

Personally, I would put it in a call anyway, but:

private ["_unit", "_selectionName", "_amountOfDamage",
"_sourceOfDamage", "_typeOfProjectile","_statusBodyParts"];
_unit = _this select 0;
_selectionName = _this select 1;
_amountOfDamage = _this select 2;
_sourceOfDamage = _this select 3;
_typeOfProjectile = _this select 4;

// modify _amountOfDamage here however you like. For example:
// _amountOfDamage = _amountOfDamage/2; // (not advised to do this, see below)
// one note: The damage passed on is damage done by the bullet + previous damage on the selection (ie previous damage was 0.2, bullet did 0.6 damage. Damage passed on would be 0.8). 
// in arma 3, I found that when setting damage with sethit, any value above or equal to 1.0, kills the unit.

// safest bet, if you want to modify damage is storing it in an array with setvariable on the unit. Grabbing the previous variable, extract that from the passed on damage (_amountOfDamage), and modify that number. 
// Then you add the outcome to this, add that to the original value and adjust _amountOfDamage with this.
// Example:
// _storedDamage = _unit getvariable "stored_damage":
// _difference = _amountOfDamage - _storedDamage;
// _amountOfDamage = _storedDamage + (_difference/2);

if (_selectionName != "") then {
_unit setHit [_selectionName, _amountOfDamage];
};

This might be what you're after? Note, you have to set damage yourself, this handler does not do that for you, thus the setHit. Feel free to PM if you got any questions.
