Works with: gta-vc.exe, 2,94 MB (3 088 896 bytes)

 

 

Remember there are no string variables in GTA VC. You can`t put [email protected] or [email protected] = "CHEAT" and pass it to function.

It will be compiled mistakenly by SB, there`s no such opcode to handle string type of variables.

You must write integers instead of strings.

 

For GTA SA find it within In-game Timecyc Editor source. It uses many dependencies.

All of your findings should be pinned. Fastman92 you should set up a site or something and put up all your works.

 

I hate it when it takes too much of my time going through the forums looking for something useful. Most of the modding section topics contains bulk, unwanted posts

I'm not good in Coding, but i want to change VC Cheat codes,

 

Let say for Exemple: i want to change ASPIRINE to ASPRO.

how do i write the Cheat String ?

I'm not good in Coding, but i want to change VC Cheat codes,

how do i write the Cheat String ?

Replacing standard cheats is bit tricky for newbies. I described it here:

http://www.gtaforums.com/index.php?showtop...st&p=1060723183

 

006D8624 ASPIRINE db 'HSPSVkVH',0

 

Encrypted ASPIRINE becomes HSPSVkVH and I shared function to decrypt and encrypt strings using GTA VC cheat algorithm.

 

Encrypted ASPRO becomes RWWTN

 

To replace cheat string we need to write into memory address of that cheat.

The code will work assuming that your gta_vc.exe has 3 088 896 bytes.

 

 

{$CLEO}// Author: fastman92// Description: ASPIRINE cheat code is replaced into ASPRO code05DF: write_memory 0x6D8624 size 4 value 0x54575752 virtual_protect false   // "RWWT"05DF: write_memory 0x6D8628 size 2 value 0x004E virtual_protect false       // "N" and NULL05DC: end_custom_thread

 

 

Must be compiled as CLEO script.

 

You can cheat strings if you happen to know the details of simple GTA VC IDB reengineering till the plugin to change the cheat strings comes out.

 

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

 

Today i created a very useful SCM function GetBaseIP for GTA VC.

It gets memory address to beginning of script content.

 

The code will work assuming that your gta_vc.exe has 3 088 896 bytes.

 

{$CLEO}05F5: call_scm_func @GetBaseIP 0 store_to [email protected]// you can do// [email protected] -= @label// to get memory address to @label   while true   wait 0   01E5: show_text_1number_highpriority GXT 'NUMBER' number [email protected] time 5000 flag 1  // See the address of script content in decimal format   end05DC: end_custom_thread:GetBaseIP// Example: 05F5: call_scm_func @GetBaseIP 0 store_to [email protected]: [email protected] = [email protected] += 0x1005E0: [email protected] = read_memory [email protected] size 4 virtual_protect false:[email protected] += 0x821280  // [email protected] += 3         // size of (03 00 00,  [email protected] = )[email protected] += @GetBasePastTheReadMemory05F6: ret 1 [email protected]
