Hammer83 0 Posted June 8, 2005 Share Posted June 8, 2005 0x464080 - GetOpcodeParameters() 0xA43C78 - Where the routine above stores opcode parameters values. Max 16 paramters for an opcode it seems. 0x53BC80 - LoadGame(char* fileName), initializes all data structures and loads fileName (which is gta.dat). 0x5B9030 - LoadMapDefinitionFile(char* fileName), parses and loads dat-files, such as default.dat and gta.dat. 0x550F10 - AllocatePools(), allocates stuff which LimitAdjuster modifies, such as Peds and Buildings. 0x82119A - malloc(size_t size) 0x438480 - Looks like cheat processor Link to post Share on other sites

jacob. 1 Posted June 9, 2005 Share Posted June 9, 2005 Stretchnutter, I had a look into XYZ and found these: Player + 368 = x pos Player + 372 = y pos Player + 376 = z pos Values appear to be read-only. Link to post Share on other sites
Stretchnutter 2 Posted June 9, 2005 Share Posted June 9, 2005 yea... these are not read only though. DWORD(CPed+0x14) + 0x30 = XPos DWORD(CPed+0x14) + 0x34 = YPos DWORD(CPed+0x14) + 0x38 = ZPos DWORD(CPed+0x14) + 0x0 to 0x2C is the rotation matrix Its much different from vice city. looks like there are a bunch of coordinates at this location.. could be the traffic cars. maybe i should write a teleporter Link to post Share on other sites
random_download 0 Posted June 9, 2005 Share Posted June 9, 2005 coords are DWords not floats? Link to post Share on other sites
ModelingMan 95 Posted June 9, 2005 Share Posted June 9, 2005 (edited) I have started to label some functions in IDA, here is my current list, it's not much but it's a start Linkage. CPed block size = 0x7C4 bytes. CVehicle block size = 0x0A18 bytes. Also the maximum amount of vehicles and peds loaded are the same as VC. coords are DWords not floats? No, read his last post, he says that the dword pointer at (CPed + 0x14) leads you to XYZ and rotation. Edit: 0x00B6F3B8 = Player CVehicle pointer. 0x00B6F5F0 = Player pointer.

Hammer83 0 Posted June 11, 2005 Share Posted June 11, 2005 ModellingMan, are you sure player struct is at address you listed? I think it might be at 0xB7CD98. IDA doesn't show any refs to 0xB6F5F0, but I must say I still have a lot of code represented as data. Link to post Share on other sites

Stretchnutter 2 Posted June 12, 2005 Share Posted June 12, 2005 (edited) If I may suggest as an evil game hacking tip: Use Dual Monitors!!! I had some problems using a debugger to set breakpoints with a single monitor. So I wondered what I could do with 2 monitors. Turns out it works great. All you need is a Video Card with dual heads, 2 monitors and a program called Ultramon (free, look on google). Click... You can do things like watch live changes to the memory.... sure you can do this in windowed mode... but noone has figured out how to yet. Sorry for going off-topic more text stuff these are wierd if you try writing something to these they dont appear because the game constantly sets the first byte to 0, but if you turn that off they operate in same manner as the busted/wasted text box. 0xBAB040 = BOTTOM TEXT BOX - stunt bonus information is written here 0xBAAEC0 = TOP MIDDLE - i dont know, some orange text 0xBAAFC0 = ? 0xBAAF40 = ? 0xBAAE40 = ?

jacob. 1 Posted June 12, 2005 Share Posted June 12, 2005 Racer, if you don't mind me asking, how do you find those textbox addresses? Do you wait until one is displayed then search for the string in memory? (ascii values of characters in order, unless they're in unicode in that case its asciichar,0,asciichar,0) This is just out of curiousity and for possible future reference to help me get better at finding addresses. I don't have duel moniters so I haven't been able to debug anything at all. I'm just waiting for someone to release a windowed-mode modification. Handling.cfg is loaded into the memory when you start a game, as are all of its parameters stored in memory offsets.. anyone know if theres a 'handling pointer' or something? I'd look into this myself if i had a debugger that worked in full-screen. Link to post Share on other sites
QJimbo 0 Posted June 12, 2005 Share Posted June 12, 2005 Hey guys, I'm having some problems with my TimeSync Tool, which basically makes the weather go mental when you freeze the time, does anyone know why? It's like there's another timer in there, maybe 16th's/256th's of a second if a single/double byte Hex value... anyone seen any values that look like that? I'm not sure why the weather keeps changing within the minute though, another timer would just make a transition repeat instead of going mental... hmm. And as for the dual monitor thing, that seems like a nice trick, but someway of getting SA running in a window would be good. 3Danalyze doesn't work, as SA seems to go "oh noes teh window" and quits Link to post Share on other sites
JernejL 63 Posted June 12, 2005 Author Share Posted June 12, 2005 i use dual monitors with geforce fx 5600, it works well but many games work improperly on dual monitors, mouse cursor is important problem here, even gtavc had problems with grabbing cursor on two monitors, zmodeler2 also doesn't work properly on dualscreen monitors - no hardware, only software renderer is availible..

aad 1 Posted June 12, 2005 Share Posted June 12, 2005 I did a try to search for some memory adresses that would be cool to use for making a trainer (im currently making one) so here is my mem adres 969160 (Flying Car cheat) its in hex so for coding it in VB use &H and then my adress. It actualy works better then the normal cheat at least it looks like it works better. Link to post Share on other sites

(ascii values of characters in order, unless they're in unicode in that case its asciichar,0,asciichar,0)This is just out of curiousity and for possible future reference to help me get better at finding addresses. i did exactly that... actually i put in a cheat and searched for "Cheat a" short for Cheat activated.. i found 3 of them... so i tryed writing something else in them and see which one had an effect... found one that worked... then jumped to the address in IDA, seen a xref to it... then just scrolled down until i saw another xref.
