[REL|SA] Spooky-style SCM Hook

[[email protected]]

I have created an SCM hook for GTA: San Andreas that works like Spooky's SCM hook for VC, with script classes and such. However, it runs next to the original SCM so the original missions will still be available. It is based on my SA Injector, so it has full CRT functionality. It also has an GXT hook for custom text entries. A lot of code is just robbed from either op9080's SA SCM hook, spooky's VC SCM Hook and my own injector, credits to them!

 

I think it is quite self-explanatory, just look at CustomScript.cpp and CustomGXT.h

 

If you're having trouble with hash_map, change #define USE_HASH_MAP in commonincs.h into #define USE_HASH_MAP_IN_STDEXT, or if that doesn't work, just delete that line. Performance will drop sligthly in that case.

Changelog:

 

v1: initial version

 

v2: added an op9080-hook-like script class

 

v3: added support for using -1 instead of actor variable, fixed some issues in opcodes.h

Does it require the DirectX SDK to be compiled? If so, for what?

Nope, it doesn't need the DX SDK .

[ceedj]

This is truly "All that." Seriously.

 

CRT stuff, multiple threads, GXT goodies ,existing SCM untouched. Egads, it's almost too good to be true. I'll provide my updated Opcodes.h here for those that use this hook.

 

Great job, [email protected]!!!

Hope it works with Visual Studio 6, if not then i really need to get an other version right away.

Everything should work, except MSVC++ 6 doesn't have the hash_map by default. You could implement it yourself, find the correct files somewhere or just update to MSVC2003, which is what I'd advise you to do . If you want to use it with MSVC6 without hash_map, comment out or delete the line #define USE_HASH_MAP in commonincs.h.

OK, I can confirm that with some changes it works with Visual Studio 2005 (VS8). Good work!

 

However, CLEO 3 scripts seem to be more user-friendly even without object-oriented programming stuff, IMO.

[[email protected]]

I've uploaded a new version, this version also supports to some extent the way op9080 uses to script in C++.

 

Example code:

theScript << interior_access << "PDOMES" << 1 << EXEC;

 

 

A bit of a 'best of both worlds' idea .

 

PS: more examples are inside the box .

[ceedj]

 

DEFINE_OPCODE(put_player, 0x0055, "vfff");DEFINE_OPCODE(create_coordinate, 0x0400, "vfffvvv");

 

 

No longer supported in SA. There are a few others; I'll weed 'em out as I go.

 

EDIT: Just a reminder: with multiple threads now, make sure your "waits" are distributed properly; this impacts which threads get higher priority. Not new info by any stretch, but after using one thread with the C++ hooks for so long, you tend to forget.

 

EDIT 2:

 

DEFINE_OPCODE(get_car_color, 0x03F3, "vii");  	// var_car col1 col2

 

 

Change the "vii" to "vvv", or your game will crash if you try to get colors from cars.

I've uploaded a new version that supports the substitution of an actor variable with -1, which is used in defining actor animation sequences. Things like

CallOpcode(&AT_look_around, -1);

should work now .

 

I also used ceedj's suggestions to modify opcodes.h, thanks for that

Just to clarify, it's not just for actors; this fix works with any opcode that takes either a handle or -1 as a parameter. When setting up opcodes in Opcodes.h, just make the parameter in question a v.

 

Hey JGS, how can we add NOT to opcodes? Doing CallOpcode(!&blapcode); throws a compilation error. I'm just creating a second opcode for now:

 

(blahpcode, "0x0684", "")

 

(nblahpcode, "0x8684", "")

 

Any ideas?

You could use

if (!CallOpcode(&..., ...))

That'll work, as it's just a C not

You know, I hate it when you make it look SO easy. Jerk.

 

Thanks buddy.

 

Oh yeah, can I use readSCMvar(blah) anywhere I need to? Would be useful for scm mods like Space's All in One, etc.

Yes, you can

[ceedj]

Sorry if this seems goofy, but I'm having a problem with this:

 

 

float* pfGravity = (float*)0x863984;*pfGravity = 0.008f

 

 

Is crashing the game. Actually, it's just the second line. I tested it further by doing this:

 

 

CallOpcode(&toggle_hud, 0);CallOpcode(&toggle_radar, 0);SCRIPT_WAIT(5000);*pfGravity = 0.008f;

 

 

Sure enough, crash after a 5 second wait. I know the addy is ok, but this is the same way I did it in Spookie's VC hook for LC. Is there something I'm missing?

[Peter]

Check out VirtualProtect, the memory address you're trying to write to is write-protected, you need to get access first

[ceedj]

I had a feeling, but wasn't sure how to do it with floats. I'll look into it some more. Thanks very much for the help.

 

EDIT: Ok, I got it to work. A bit inelegant though. Sacky gave me this for my custom loading screens:

 

 

void Patch_DEF ( DWORD dwAddress,  BYTE *bRawData, int iSize ){DWORD dw[2];VirtualProtect ( (PVOID) dwAddress, iSize, PAGE_EXECUTE_READWRITE, &dw[0] );memcpy ( (PVOID) dwAddress, bRawData, iSize );VirtualProtect ( (PVOID) dwAddress, iSize, dw[0], &dw[1] );}

 

 

My code for gravity:

 

BYTE bGravity[] = { 0x6F, 0x12, 0x83, 0x3B };Patch_DEF(0x863984, bGravity, 4); 

 

 

That translates to 0.004, (3B83126F) or half-gravity. My question: can anyone suggest a way to use the float value instead? Not a huge deal, but I want to add gravity values to my config file; I think 1 float is easier to deal with than hex combos. Thanks.

DWORD dw[2];VirtualProtect ( (PVOID) 0x863984 , 4, PAGE_EXECUTE_READWRITE, &dw[0] );*(float*)0x863984 = 0.004f;VirtualProtect ( (PVOID) 0x863984 , 4, dw[0], &dw[1] );

 

 

[ceedj]

Thanks for that; there's not nearly enough examples on how to best use SA memory stuff with C++.

In-process its better to use Pointer stuff

Just wait until you figure out what you can do with hooking full functions, you'll be amazed

That is the absolute nicest way I've ever been called a complete idiot. Thanks.

If you want a nice little float patch function try this:

 

 

void Patch_Float(DWORD dwAddress,float fltData){char* cTmp = (char*)&fltData;BYTE bTmp[] = { cTmp[0], cTmp[1], cTmp[2], cTmp[3] };Patch(dwAddress,bTmp);}

 

 

Use:

 

 

Patch_Float(0x863984,0.008f);

 

[ceedj]

Bee-u-ti-fal! Thanks Sacky.

 

 

DEFINE_OPCODE(set_car_speed_now, 0x04AB, "vf");	

 

 

Switch to 04BA.

Bee-u-ti-fal! Thanks Sacky.

 

 

DEFINE_OPCODE(set_car_speed_now, 0x04AB, "vf");	

 

 

Switch to 04BA.

Fixed

 

Furthermore:

 

void Patch_Float(DWORD dwAddress,float fltData){   Patch(dwAddress,*((DWORD *)&fltData));}

 

This might be a little bit neater, but it doesn't matter much .

care to list those changes? i tried building the project in VS 2005 Express, and get a hefty 39 errors, 20 warnings.

[Seemann]

Well, I have VS2008 Pro, so you might have problems with the Platform SDK, do you have one?

 

I just checked the latest version and all I was need to do is to comment out the line '#define USE_HASH_MAP' in the commonincs.h to get the project compiled successfully.

 

It's strange as I remember I replaced all occurences of the 'strcpy' function with the 'strcpy_s' one in one of the previous releases.

 

What errors do you get?

[DexX]

 

Well, I have VS2008 Pro, so you might have problems with the Platform SDK, do you have one?

due to the size of the PSDK, i don't update it very often (i'm on 56k), so i have the same version i installed about a year ago. and to say i have "problems" with it, is to describe my entire experience with it!

 

as for the errors, here's my buildlog before i comment out the hash map line...

and after...

After i comment it out, i get a mere 3 errors.

It seems that your advapi32.lib is too old. The functions RegQueryValueEx and RegOpenKey have been introduced in Windows 2000, and I think your platform SDK is pre-2000. I uploaded the my advapi32.lib here: http://jesse.thorbit.nl/sainject/rotzooi/AdvAPI32.Lib

 

Edit: or do you actually have a pre-2000 Windows version?

 

Edit edit: it may be that these functions already existed prior to Windows 2000, I don't really get the MSDN sometimes

 

Edit edit edit: after you've downloaded advapi32.lib, you have to link your application against it of course

Greetings.

 

Having a small problem; I have a function that works in one thread but seems to be ignored in others. Any ideas on why this might be? Could this be similar to a problem I have with a set of action sequences (SA code) I have that all work in the main animation thread, but not the secondary one?

 

EDIT: Ok, it loads at the beginning of the thread I want, just not at the point in the thread that I want...

 

Sigh. Any way I can just take the post back? No? Ok, might as well complete the embarrassment...

 

 

StoreMainCheck13:if (TrailerCheck4 == 1){pTrailer4->GetCarCoord(&fT4X, &fT4Y, &fT4Z);pTrailer4->GetCarZ(&fT4Zangle);//if (FileStore == 1)pGame->TextNow("STORE", 5000, 1);FileSavePosition();StoreAll = 1;goto CreatePed1;} else { StoreAll = 1; pGame->TextNow("STORE", 5000, 1); goto CreatePed1;}}

 

 

Yeah, that's right. I need to put FileSavePosition(); after the ELSE as well. What annoys me is that I spent several hours trying to figure this out, and I KNEW it would be something stupid. Gah. Sorry for the trouble.

 

EDIT: In case anyone's interested, this is my resulting output file (go me!):
