Reduced Explosive Damage at Edge

Amineri · April 29, 2014

Having picked up a lot of tricks in the last few months, I finally have revisited this topic and was able to mod in variable explosive damage depending on distance from the blast center.

Once I knew where to put the code, this actually turned out to be a pretty simply change, only requiring insertion of new code in a single function, XComUnitPawn.TakeDirectDamage. TakeDirectDamage is called for each unit that takes AoE damage from XComUnitPawn.TakeSplashDamage.

The new code looks like :

    if(ClassIsChildOf(Dmg.DamageType, class'XComDamageType_Explosion'))
    {
        if(XComProjectile(Dmg.DamageCauser) != none)
        {
            actualDamage.DamageAmount = int(0.50 + (float(Dmg.DamageAmount) * (1.0 - FMin(1.0, (0.50 * VSize(Dmg.DamageCauser.Location - Location)) / XComProjectile(Dmg.DamageCauser).DamageRadius))));
        }
    }
    actualDamage.DamageAmount = kSelf.OnTakeDamage(actualDamage.DamageAmount, Dmg.DamageType, kDamageDealer, Dmg.HitLocation, Dmg.Momentum, Dmg.DamageCauser);

The above code is only applied to projectiles dealing explosive damage (including of type XComDamageType_NeedleExplosion, which is a child of XComDamageType_Explosion). The above equation scales the damage down to 50% of regular damage at the edge of the blast, with 100% damage at the center, scaling down linearly. Fractional damage is rounded instead of truncated, so a 3 base damage blast will still deal 2 damage at the edge, and a 5 damage blast will deal 3 at the edge.

The Dmg and actualDamage variables are UnrealEngine natively defined structure, defined in Engine.upk, in Actor.DamageEvent :

struct native DamageEvent
{
    var int DamageAmount;
    var Actor EventInstigator;
    var Vector HitLocation;
    var Vector Momentum;
    var class<DamageType> DamageType;
    var TraceHitInfo HitInfo;
    var Actor DamageCauser;
    var bool bRadialDamage;
    var float Radius;
    var bool bIsHit;
    var array<Actor> IgnoredActors;
    var Actor Target;
    var bool bDamagesUnits;
    var bool bCausesSurroundingAreaDamage;
    var bool bDebug;
    var Box FilterBox;
    var Actor kShot;
}

The key part here is that DamageEvent contains both the EventInstigator (the unit that originated the projectile) and the DamageCauser (the projectile itself). Both members are of type Actor, but Actor is a parent class of both XGUnit and XComProjectile, which is why they have to be cast to the correct type.

Below is the UPKmodder file which implements the mod :

Unfortunately this has a second effect code for Long War, which is enabling HTML tag pop-ups for absorbed damage :

//if(XGUnit(GetGameUnit()) != null)
07 29 04 77 2E 3F CE 00 00 1B 06 39 00 00 00 00 00 00 16 2A 16 

	//XGUnit(GetGameUnit()).SetTimer(0.5, false, 'DebugTreads')
	19 2E 3F CE 00 00 1B 06 39 00 00 00 00 00 00 16 13 00 00 00 00 00 00 61 18 1E 00 00 00 3F 28 21 7E 17 00 00 00 00 00 00 4A 16

The above code will probably cause crashes if installed into vanilla code. To implement the absorbed damage pop-ups for Long War required rewriting XGUnit.AbsorbDamage (to save the last absorbed damage amount) and XGUnit.DebugTreads into a helper to invoke the Messager to create the pop-up.

This code should be removed (requiring adjustment of the jump offsets) if creating a patch for vanilla Enemy Within.

I've converted your mod to PatchUPK format, but I have a question before I post it here.

XComProjectile(Dmg.DamageCauser) is used in two places and in both it casts XComFracLevelActor.TakeDirectDamage.Dmg instead of XComUnitPawn.TakeDirectDamage.Dmg. Is it intentional? In all other places XComUnitPawn.TakeDirectDamage.Dmg is used, which is an input parameter of XComUnitPawn.TakeDirectDamage function. Both EventInstigator and DamageCauser are members of XComUnitPawn.TakeDirectDamage.Dmg, as I understand it, and XComFracLevelActor.TakeDirectDamage.Dmg is actually a different object, which isn't accessible from this function by regular Unreal Script means.

Nice catch, thank you very much :)

There were indeed two references to XComFracLevelActor.TakeDirectDamage.Dmg which I hadn't fixed after copying the reference code from that function. The crazy thing is that it appeared to all work properly in my test case, which could have led to some maddeningly-inconsistent bugs.

Here's my updated UPKmodder file with the references corrected, in case anyone is interested :

MODFILEVERSION=4
UPKFILE=XComGame.upk

// enable absorbed damage pop-ups

As a follow on project, following some discussion in the Long War beta forum, I might create a separate module that would scale the environmental damage for explosives based on distance from blast as well.

I've coded up the second part to the mod that scales environmental damage down based on distance from the explosion center. This only applies to explosive-type effects, not flamethrower, fires, plasma, KSM body flying, etc.

At the same time I also added a +/- 25% randomization to the environmental damage, applied separately to each XComDestructibleActor component.

The code is added to XComDestructibleActor.ApplyDamageToMe, just after the environmental damage is retrieved but before it is saved/applied :

    if(ClassIsChildOf(Dmg.DamageType, class'XComDamageType_Explosion'))
    {
        if(XComProjectile(Dmg.DamageCauser) != none)
        {
            DamageAmount = int(0.50 + (float(DamageAmount) * (1.0 - FMin(1.0, (0.50 * VSize(Dmg.DamageCauser.Location - Location)) / XComProjectile(Dmg.DamageCauser).DamageRadius))));
        }
    }
    if(DamageAmount > 0)
    {
        DamageAmount *= (0.750 + (0.50 * FRand()));
    }

I've gone through and I'm pretty sure all of the Dmg references are to XComDestructibleActor.ApplyDamageToMe.Dmg.

The full UPKmodder file is here:

-----------------

I also created a second little optional mod for this that applies an 8x scaling factor to difficulty-based alien bonus damage (by default it simply adds the bonus damage). This is applied in XGTacticalGameCore.CalcEnvironmentalDamage :

    iDamage = m_arrWeapons[iWeapon].iEnvironmentDamage + (8 * aCurrentStats[12]);

For vanilla environmental damage values this isn't necessary, since all plasma weapons have 125 environmental damage, enough to destroy any DestructibleActor except a car (which has 250 toughness). However if the environmental damage numbers in the DGC.ini are modded down this may be of interest (we've done this in Long War).

The full UPKmodder file :

MODFILEVERSION=4
UPKFILE=XComGame.upk
GUID=1C 18 A1 1A 2B C3 34 4E 8B 2C 72 33 CD 16 7E 3E // XComGame_EW_patch3.upk
FUNCTION=CalcEnvironmentalDamage@XGTacticalGameCore

// apply scaling to bonus damage for environmental damage
