Hi everyone,

I'm trying to create a script/trainer for the mentioned game version and run into a problem. Could someone please help me troubleshoot this problem?

I found the selected city's culture to be at 2D919E9C having value of 15.

Disassembler information on the desired address:

Code:
CvResourceInfo::isFeatureTerrain+20 - 8B 81 10020000  - mov eax,[ecx+00000210]
CvResourceInfo::isFeatureTerrain+26 - 8B 4C 24 04  - mov ecx,[esp+04]
CvResourceInfo::isFeatureTerrain+2A - 8B 04 88   - mov eax,[eax+ecx*4]
CvResourceInfo::isFeatureTerrain+2D - C2 0400 - ret 0004
CvPlayerColorInfo::GetColorTypePrimary - 8B 81 04010000  - mov eax,[ecx+00000104]
CvPlayerColorInfo::GetColorTypePrimary+6 - C3 - ret
CvPlayerColorInfo::GetColorTypePrimary+7 - CC - int 3


Debugging information for accessing the desired address:

Code:
0703A11A - 8B 04 88   - mov eax,[eax+ecx*4]
0703A11D - C2 0400 - ret 0004
0703A120 - 8B 81 04010000  - mov eax,[ecx+00000104] <<
0703A126 - C3 - ret
0703A127 - CC - int 3

EAX=0000000F
EBX=00000400
ECX=2D919D98
EDX=432C09C0
ESI=10DE2400
EDI=2D919D98
ESP=0018FAFC
EBP=00000001
EIP=0703A126


My AA script segments:
Code:
_CityCulture:
 mov [pCityCulture],ecx
// mov [pCityCulture],edi

 cmp [iCityResources],0
 je _ExitCityCulture

 mov eax,[ecx+00000104]
 cmp eax,[iCityCulture]
 jge _ExitCityCulture
 mov eax,[iCityCulture]
 mov [ecx+00000104],eax
 jmp _BackCityCulture

_ExitCityCulture:
 mov eax,[ecx+00000104]
 jmp _BackCityCulture

"CvGameCoreDLLFinal Release.dll"+CA120:
jmp _CityCulture
nop
_BackCityCulture:

[DISABLE]
"CvGameCoreDLLFinal Release.dll"+CA120: // city culture
mov eax,[ecx+00000104]


In the table, I've added a pointer pCityCulture+104 but it points to the wrong address with a different value. I've also tried it mov [pCityCulture],edi but still shows the incorrect address and value. This is done within the same turn.

Thanks for your time.

The code you found is accesses by other stuff. In this case, it's accessed for every CvPlayerColorInfo object whenever GetColorTypePrimary is called

You will have to find a way to distinguish between cities and playercolors and then the specific city at that.

Perhaps you can find a different better address.
Tip: Look at the economics view when using find what accesses. Or do a next turn

Thanks DB for the reply. You're right. After some more digging, I got the right address I was looking for.
