Additional tweakable constants

[Amineri]

For those of you that like tweaking constants, I came across another set of them. (( not totally sure if this has been posted before, but at the risk of duplication, here goes ))

 

These are all found in the XGTacticalGameCoreNativeBase << XcomGame.upk

 

Of particular interest (in my opinion):

• const LOW_COVER_BONUS = 20;
• const HIGH_COVER_BONUS = 40;
• const HUNKER_BONUS = 2.0;

• const BASE_NUM_ROCKETS = 1;
• const ROCKETEER_BONUS_ROCKETS = 1;

• const BASE_SMOKE_BOMBS = 1;
• const SMOKEANDMIRROR_BONUS_BOMBS = 1;
• const DENSE_SMOKE_RADIUS_MULT = 1.25f;
• const DENSE_SMOKE_DEFENSE_BONUS = 20;
• const SMOKE_BOMB_DEFENSE_BONUS = 20;

• const HEATAMMO_DMG_MULTIPLIER = 2;

• const DEATH_DAMAGE_CYBERDISC = 3;
• const DEATH_RADIUS_CYBERDISC = 192.0f;
• const DEATH_DAMAGE_SECTOPOD = 5;
• const DEATH_RADIUS_SECTOPOD = 320.0f;
• const DEATH_DAMAGE_ETHEREAL = 4;
• const DEATH_RADIUS_ETHEREAL = 144.0f;

(for those who beefed up cyberdiscs and sectopods, now you can make the helpers more annoying ^_^ ))

• const DRONE_REPAIR_HP = 3;
• const DRONES_PER_CYBERDISC = 1;
• const DRONES_PER_SECTOPOD = 3;

• const MINDMERGE_CRIT_BONUS = 25;
• const MINDMERGE_HP_BONUS = 1;

( make those rookies panic longer !! ^_^ ))

• const PANIC_TURNS = 1;
• const PANIC_RANDOM_TURNS = 0;

• const STUN_I_HP_THRESHHOLD = 3;
• const STUN_II_HP_THRESHHOLD = 6;
• const STUN_BASE_CHANCE = 70;
• const STUN_MAX_CHANCE = 95;
• const STUN_MIN_CHANCE = 1;

note, when it says "bonus", I think it really means "penalty" -- as in a negative bonus is a penalty))

• const REACTION_BONUS_FOR_OVERWATCH = 20;
• const REACTION_BONUS_FOR_DASH = 20;

(tracer beams = holo-targetting, I think))

• const TRACER_BEAMS_BONUS = 10;

I'm hiding the full list in a spoiler, because there are a LOT more of them:

Unfortunately, we've learned that editing these does nothing. These are representative values, but the "real" values the game refers to are apparently embedded in the exe somewhere.

[Amineri]

Right. It just clicked as to what these are about. Many other places in the code are code chunks that look like:

 

XComGameReplicationInfo(class'Engine'.static.GetCurrentWorldInfo().GRI).m_kGameCore.20

 

 

I'd been curious as to why the method after m_kGameCore would be a constant number and not a method / variable. But I think the compiler optimizer is replacing these calls with the constant values at compile time.

For example:

if(m_bHasHeightAdvantage)

{

kInfo.arrHitBonusStrings.AddItem(m_strHeightBonus);

kInfo.arrHitBonusValues.AddItem(XComGameReplicationInfo(class'Engine'.static.GetCurrentWorldInfo().GRI).m_kGameCore.20);

}

Compare this with the "const HEIGHT_OFF_BONUS = 20;" definition in XGTacticalGameCoreNativeBase, and it looks like the compiler set the value in the above snippet at compile time, using the const values.

While not as nice and pretty (or quick) as directly being able to change the const values themselves, this does provide some help in finding where all of the const values are being applied.

For example, const CLUSTER_BOMB_PREVIEW_RADIUS = 432;

If I do an "all file" search with Notepad++, searching for XComGameReplicationInfo(class'Engine'.static.GetCurrentWorldInfo().GRI).m_kGameCore.432

I find the following two files:

XGAbility_ClusterBomb, line 88

and

XGAIBehavior_Sectopod, line 60

Unfortunately some of the values are used in native code, and some values are very common, but it could provide some help when trying to change a particular value.

Could this be the reason empty params do 't show up in UE Explorer? Some compile-time mechananism? Anyway where should be then the place to approach any attemp to change those constant values? I looked at where they're difined (not at the pc now), but I couldn't distinguish the values they were suposed to express

[johnnylump]

To change those constants -- if they are in the upk, and not the exe, you'll have to find them in the functions where they are in play.

 

Empty optional parameters are sometimes marked with a4 bytes, which don't show up in object mode in explorer but do in the hex. (Not sure if that's what you are referring to)

[Amineri]

@anUser

To find the values, you have to search for where they are actually applied. If it's in the .exe (as is the case for the stun values), then you can't use UE Explorer to find them. If it's in one of the .upks then there is a better chance.

 

It seems like those constants (as well as other things) are referenced using the:

 

XComGameReplicationInfo(class'Engine'.static.GetCurrentWorldInfo().GRI).m_kGameCore.###

 

when UE Explorer decompiles. I have a set of all the decompiled files (a little old, but still useful) in a directory, and use Notepad++ to search all files in the directory for particular strings.

 

So, you can use the above tag combined with the decimal value of the constant you want to change to find all instances where it is assigned (but if it is a common value like 20, it may get ugly), or try and read through the files directly.

 

Just a couple of options...

[anUser]

Any success so far changing those m_kGameCore.xx?

Yeah johnny that's what I meant, but nevermind, I kinda mixed concepts when thinking that
