Help please - want a script or mod to reduce critical multiplier to 1.2

[sniggles]

Hi guys - i really could use some help to make a quick mod to reduce the critical multiplier from 1.5 to 1.2.

 

I am using Enemy Within with all DLC and latest patch (patch 3)

 

I know nothing about UPK editing and hex editing etc and just want to make this small change to my game.

 

From this forum i understand the code is..

 

if(bCritical)
{
iDamage += 1;
iDamage = int(float(iDamage) * 1.50);
iDamage += class'XComEngine'.static.SyncRand(3, string(Name) @ string(GetStateName()) @ string(GetFuncName())) - 1;
return iDamage;
}

 

and it is in either XComGame.upk or XComStrategyGame.upk

 

not sure which.

 

I just want to change the * 1.5 to * 1.2

 

Can anyone help me out with a txt file script i could use with latest 'Patcher GUI (4.0) way of modding.

 

I am already using a number of mods using this excellent utility and fully understand how to prepare my game for modding and load the mods - i just don't know how to find the hex code and write the txt script to create my own mod.

 

I could even have a go writing the txt file myself if i just had the modified hex code line i need to insert and the UPK file name.

 

Really appreciate any help or advice.

 

All the best,

 

Mark.

You sure that simply changing the DGC.INI value won't do what you need? See the 'How to DIY common mod solutions' wiki article.

Thanks for the reply Dubios but you can't reduce the actual critical damage output calculation using the DefaultGameCore.ini - only the critical hit chance.

 

I have already set all the critical bonuses to zero for the weapon stats and balancing section and criticals still occur quite often using the 1.5 X base weapon stat calculation (randomized with a dice throw).

 

I have modded my game to be high hp and low damage weapon output for long tactical battles but i need to reduce the high critical calculation to something like 20% as the current dice rolls are giving way too high a critical damage output for my mod.

 

Here's hoping someone can find the hex code i need to change.

[sniggles]

Well - attempted to make my own changes and mod - FAIL!

 

I got as far as locating the code which was in...

 

XComGame.upk / XGTacticalGameCore / CalcOverallDamage

 

but couldn't work out how to find the decimal 1.50 when you view the hex code.

 

So - got close but no cigar - in case anyone can point me in the right direction i will copy and paste the script and corrosponding hex code below so maybe someone can point out where the multiplier 1.5 in hex is shown?

 

 

 

function int CalcOverallDamage(int iWeapon, int iCurrDamageStat, optional bool bCritical, optional bool bReflected)
{
local int iDamage, iRandDamage;

bCritical = false;
bReflected = false;
iDamage = m_arrWeapons[iWeapon].iDamage + iCurrDamageStat;
// End:0x54
if(bReflected)
{
return 0;
}
// End:0x76
if(WeaponHasProperty(iWeapon, 9))
{
return iDamage;
}
// End:0x114
if(IsOptionEnabled(0))
{
iRandDamage = 1 + class'XComEngine'.static.SyncRand(int(float(iDamage) * 1.50), (string(Name) @ string(GetStateName())) @ string(GetFuncName()));
// End:0x10A
if(bCritical)
{
return iDamage + iRandDamage;
}
// End:0x114
else
{
return iRandDamage;
}
}
// End:0x1A4
if(bCritical)
{
iDamage += 1;
iDamage = int(float(iDamage) * 1.50);
iDamage += (class'XComEngine'.static.SyncRand(3, (string(Name) @ string(GetStateName())) @ string(GetFuncName())) - 1);
return iDamage;
}
iDamage = (iDamage + class'XComEngine'.static.SyncRand(3, (string(Name) @ string(GetStateName())) @ string(GetFuncName()))) - 1;
// End:0x217
if(iDamage < 1)
{
iDamage = 1;
}
return iDamage;
//return ReturnValue;

 

 

 

and the hex code looks like (not sure if this will paste okay)

Appreciate any help guys as i know nothing about hex editing

[dubiousintent]

Changing an existing function in XCOM is not as simple and straightforward as one might think. You need to use UE Explorer as well. See "Hex editing UPK files" which outlines the process. Suggest the "Hex values XCOM Modding" article may also help.

 

Otherwise, you need to get the attention of one of the "code divers", who are plenty busy on their own projects. (I'm just the librarian.)

Floats are marked by the byte 1e ... the four following bytes make up the value, although they are in reverse order from what you might expect.

 

So, 1.5 will appear in the code as

1e 00 00 c0 3f

 

And 1.2 is

1e 9a 99 99 3f

 

I use this to convert floats to hex:

http://gregstoll.dyndns.org/~gregstoll/floattohex/

 

Use explorer's tokens and buffer modes to get a feel for how hex translates into code.

[sniggles]

Thanks Johnnylump - really appreciate you taking the time to help a newbie modder.

 

Now you have helped me identify the 1.5 multipliers i can crack on and thanks also for saving me the hassle of working out what 1.2 would be in hex code.

 

I have to go out in a while to visit family ( real life getting in the way of my gaming again - lol ) so i will create my mod to reduce the random damage mult and crit dam mult to 1.2 later today.

 

If all goes well after testing in game i will report back the gameplay results in case this change appeals to others on this excellent forum.

 

Thanks again.

 

Good luck with your modding.

 

Mark.

[sniggles]

Johnylump you are a GOD! - thanks again - made my own quick changes using your references for 1.5 and 1.2 and VOILA - reduced the random damage and critical bonuses from 50% to 20%.

 

Been testing it out all afternoon / evening and works perfectly with no problems and the extreme damage calculations have been reduced significantly just like i wanted.

 

I will paste below the new ' CalcOverallDamage ' script after my hex edits to the ' XComGame.upk ' file..............

 

 

function int CalcOverallDamage(int iWeapon, int iCurrDamageStat, optional bool bCritical, optional bool bReflected)
{
local int iDamage, iRandDamage;

bCritical = false;
bReflected = false;
iDamage = m_arrWeapons[iWeapon].iDamage + iCurrDamageStat;
// End:0x54
if(bReflected)
{
return 0;
}
// End:0x76
if(WeaponHasProperty(iWeapon, 9))
{
return iDamage;
}
// End:0x114
if(IsOptionEnabled(0))
{
iRandDamage = 1 + class'XComEngine'.static.SyncRand(int(float(iDamage) * 1.20), (string(Name) @ string(GetStateName())) @ string(GetFuncName()));
// End:0x10A
if(bCritical)
{
return iDamage + iRandDamage;
}
// End:0x114
else
{
return iRandDamage;
}
}
// End:0x1A4
if(bCritical)
{
iDamage += 1;
iDamage = int(float(iDamage) * 1.20);
iDamage += (class'XComEngine'.static.SyncRand(3, (string(Name) @ string(GetStateName())) @ string(GetFuncName())) - 1);
return iDamage;
}
iDamage = (iDamage + class'XComEngine'.static.SyncRand(3, (string(Name) @ string(GetStateName())) @ string(GetFuncName()))) - 1;
// End:0x217
if(iDamage < 1)
{
iDamage = 1;
}
return iDamage;
//return ReturnValue;

 

 

As you can see the 2 damage mult references are now *1.2 instead of *1.5

 

 

I don't know how to make a mod script to use with the Patcher GUI utility and so i just edited the XComGame.upk directly using Hxd.

 

If anyone wishes to do the same i will paste my own mod reference procedure that i wrote for myself below....

 

 

USE HxD HEX EDITING UTILITY TO HACK THE ' XComGame.upk '

1.5 MULT

--------

1E 00 00 C0 3F

1.2 MULT

--------

1E 9A 99 99 3F

RANDOM DAMAGE

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

ORIGINAL (1.5 MULT) HEX STRING

00 33 86 00 00 1E 00 00 C0 3F 16 A8 A8 38 57 01

REPLACE CODE (1.2 MULT)

00 33 86 00 00 1E 9A 99 99 3F 16 A8 A8 38 57 01

CRITICAL DAMAGE

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

ORIGINAL (1.5 MULT) HEX STRING

00 33 86 00 00 1E 00 00 C0 3F 16 A1 00 33 86 00

REPLACE CODE (1.2 MULT)

00 33 86 00 00 1E 9A 99 99 3F 16 A1 00 33 86 00

Most people will understand how to use HxD to change hex code but if you need any more clearer instructions or a step by step then just post a quick reply.

[johnnylump]

Glad you got it working; anything we can do to increase the tiny population of modders willing and able to do hex work is a good thing :)
