In VC, R* removed opcode 0367 - headshot rampage - for unknown reasons. To enable headshot rampage, setting 0x4576F0 to 1 will make the default rampage opcode 01F9 behave exactly like 0367. Or if you want to enable headshots after 01F9 is executed, set 0xA10B94 to 1. It does the same job.

An indirect gift from Rockstar; the libNative.so file in the Android version of III contains function and variable labels, which is understandable since it's a library build. Functions which didn't exist in the PS2 version can now be found in the Android version (e.g. the infamous debug/movie menu is actually the CSceneEdit class, and the variable to enable it is called CSceneEdit::m_bEditOn).

Should be interesting for those who are interested.

How can this be read and used? Is it just a list like what DexX/Ghost Bear had?

-dexx edit;
The list is all ghost bear's. I only re-host it because his original site went down.

Disassembling the file with an advanced disassembler like IDA will allow you to see these functions and variables, then, by comparison to the PC version, you can label the functions and variables in your x86 disassembly. Having this information will better our understanding of the functions and variables in the game.

Thanks This should come in handy. I'll try to add to it.

[Swoorup]

Oo Thank you @towncivilian

Don't someone or a team keep/update a list of functions and variable names whenever they are found?
If they do, do they have a site to keep those work synced or something?

[spaceeinstein]

That's a great idea. I will update the page at GTAModding with what I know. The site is a little broken due to some kind of corruption but you should be able to edit basic text into the site.

Thats a ton of functions. Damn how do you discover them?

[ModelingMan]

Here's a current list of my labelled functions for VC.

[Swoorup]

@ModelingMan

I have a request. Can you please convert or upload an txt version of your VC functions instead of htm in your site? I am having very low internet connections right now (dial up ) so I cant download the htm file itself because my Download Manager is unable to query its size (it doesnot download it fully). Perhaps it would if it were a txt.
Also do you have IDB version?

Also I have a question.
At 0x00578640 you have defined the function as

CODE

CSprite2d::Draw((CRect const &,CRGBA const &,CRGBA const &,CRGBA const &,CRGBA const &))

But the idb posted by town civilian defines that function as this

CODE

void __thiscall CTexture__draw(CTexture *, RwRect *posInfo, RwRGBA *v1_color, RwRGBA *v2_color, RwRGBA *v3_color, RwRGBA *v4_color)

I am making a HUD for VICE using this function and found out that void __thiscall CTexture__draw works perfectly. Anyway my question is why is it different, why is CTexture * parameter missing?
My guess for what I have found from site is that it is the hidden this pointer used in member function. But really I am not sure.
Can you please elaborate to me?

Also if you don't mind can you tell me how to initialise the CSprint2D class? Like can I set normal texture with different posInfo and alpha with different posinfo and draw them on to the screen? What I need to do is I need to constantly keep altering the bar value using a normal texture(rectangle shaped) with respect to player's health. And the alpha texture would be used but not altered to keep a rounded borders at the end of the bar( it would have same posinfo every time).

QUOTE (ModelingMan @ Feb 19 2010, 01:51)

I started up a little something I was working on a couple years ago. At first it started off wrapping D3D8 calls to D3D9. After that failed, I turned to redirecting all the referenced Renderware functions of VC to the Renderware 3.6 libs I have, which seems to be working so far. If you've ever used the RW libs you'll recognize the logo in the bottom left corner. My plan was to use the RW functions from the SA executable and redirect the functions in VC (and probably III) to them. This could allow more advanced graphics hacks for VC and III (HLSL shaders, etc.).

Is this a pipe dream?
Think i'll better make a program that documents VC functions and addresses, opcodes with tons of descriptions actually for my own purpose. so yeah....

EDIT: CRadar uses this function 004C1A20 CRadar::DrawRadarMask((void)) to make alpha mask for radar textures to give a round shape. I am sure this is done dynamically and is exactly what I need to draw that rounded HUD. Try nopping the address that calls 004C1A20 CRadar::DrawRadarMask((void)) and you will see the difference.

004C1A20 CRadar::DrawRadarMask((void)) uses the function 00577D10 CSprite2d::SetMaskVertices((int,float *)) inside it somewhere but I am confused about its parameters and how it works. I need to know how it applies mask to selected texture and about how position data are set. But now I am sure this will get my mod done.

@Swoorup
Because it is thiscall.

Is there any information about CScriptThread in GTA3?

Just noticed the VCFunctions.txt in your site @ModelingMan.

But unfortunately the link is broken.
Never mind though, I have downloaded the htm file itself a tons of file just to make sure everything was downloaded fully.
The last function was 005B3120 cTransmission::InitGearRatios((void)

Anyone anything about memory structures of VC? A lot of things for structures are still undocumented. Camera, Entity. I need things like that desperately.

To have SA like Vehicle Cam: Nop the call at 0x46C62E.
NOP 5 bytes.

Warning: Nop that before you actually start the game.

This works best when you are in bike though.

EDIT: I finally figured out how the radar masking works. But still I need to apply the same technique to my own textures which have not been done yet.

004C1A20 CRadar::DrawRadarMask((void)) is called before every frame rendering if radar is enabled at the menu. The function then uses 00577D10 CSprite2d::SetMaskVertices((int numOfVertices,RwV2D* verticesOfPolygon[numofVertices])) to set up 4 polygons into which the extra radar textures are too be masked/erased out.

The polygons are formed at each of the corners of the square (before masking). In a corner 8 sets of points/vertices are assigned to represent the polygon layer which is to be erased out and the polygon points are passed to CSprite2d::SetMaskVertices((int numOfVertices,RwV2D* verticesOfPolygon[numofVertices])) and some renderware functions are carried out.

CODE

signed int __cdecl CRadar__DrawRadarMask() {  signed int v0; // ebx@1  double v1; // st6@2  double v2; // st7@2  double v3; // st4@3  double fradarDiameterExact; // st5@4  double v5; // st5@4  signed int v6; // ebp@5  long double v7; // st4@6  long double v8; // st6@6  __int16 v9; // fps@6  long double v10; // st4@8  __int16 v11; // fps@8  double v12; // st4@10  float v13; // ST0C_4@10  double v14; // st5@11  signed int v15; // eax@12  double v16; // st5@12  double v17; // st5@12  float v19; // [sp+0h] [bp-68h]@8  unsigned int v20; // [sp+8h] [bp-60h]@1  unsigned int v22; // [sp+Ch] [bp-5Ch]@1  unsigned int v24; // [sp+10h] [bp-58h]@1  unsigned int v26; // [sp+14h] [bp-54h]@1  unsigned int v27; // [sp+18h] [bp-50h]@1  unsigned int v25; // [sp+1Ch] [bp-4Ch]@1  unsigned int v23; // [sp+20h] [bp-48h]@1  unsigned int v21; // [sp+24h] [bp-44h]@1  float v28; // [sp+28h] [bp-40h]@3  float v29[15]; // [sp+2Ch] [bp-3Ch]@5  v20 = 0x3F800000u;  v21 = 0xBF800000u;  v22 = 0xBF800000u;  v23 = 0xBF800000u;  v24 = 0x3F800000u;  v25 = 0x3F800000u;  v26 = 0x3F800000u;  v27 = 0xBF800000u;  RwRenderStateSet(rwRENDERSTATETEXTURERASTER, 0);  RwRenderStateSet(rwRENDERSTATESRCBLEND, 5);   // nothing  RwRenderStateSet(rwRENDERSTATEDESTBLEND, 6);  // nothing  RwRenderStateSet(rwRENDERSTATEFOGENABLE, 0);  // nothing  RwRenderStateSet(rwRENDERSTATETEXTUREFILTER, 2);// nothing  RwRenderStateSet(rwRENDERSTATESHADEMODE, 1);  // nothing  RwRenderStateSet(rwRENDERSTATEZTESTENABLE, 0);// Nothing  RwRenderStateSet(rwRENDERSTATEZWRITEENABLE, 1);// Results no mask  RwRenderStateSet(rwRENDERSTATEVERTEXALPHAENABLE, 1);// Results black color in masked area  RwD3D8SetRenderState(0x19u, 8u);  v0 = 0;  do  {    v2 = *(&v20 + 2 * v0);    v1 = *(&v22 + 2 * v0);    if ( CMenu.IsOnMapMenu )    {      v28 = (fradarScaleX * CMenu.mapScale * v2 + flt_68FD10 * CMenu.mapScale + CMenu.mapPos.x)          * SLODWORD(pResolutionX)          * fradarDiamMultiplier;      v3 = (CMenu.mapPos.y - flt_68FD1C * CMenu.mapScale - flt_68FD18 * CMenu.mapScale * v1)         * SLODWORD(ResolutionX)         * fradarUpScaleMul;    }    else    {      fradarDiameterExact = SLODWORD(pResolutionX) * fradarDiamMultiplier * fradarDiameterWRT640;      v28 = v2 * fradarDiameterExact * fradarBy2Divider + fradarDiameterExact * fradarBy2Divider + fradarPosX;      v5 = SLODWORD(ResolutionX) * fradarUpScaleMul;      v2 = fradarScaleY * v5;      v3 = v2 * fradarBy2Divider + SLODWORD(ResolutionX) - fradarPoxYfromBottom * v5 - v1 * v2 * fradarBy2Divider;    }    v29[0] = v3;    v6 = 0;    do    {      v8 = v6 * fradarCurvatureUnk * fradarCurvatureUnk2;      v7 = cos(v8);      UNDEF(v9);      if ( v9 & 1024 )        v7 = cos(MakeAngleAccute(v2));      v19 = v7;      v2 = *(&v20 + 2 * v0) * v19;      v10 = sin(v8);      UNDEF(v11);      if ( v11 & 1024 )        v10 = sin(MakeAngleAccute(COERCE_FLOAT(COERCE_UNSIGNED_INT64(*(&v20 + 2 * v0) * v19))));      v13 = v10;      v12 = *(&v22 + 2 * v0) * v13;      if ( CMenu.IsOnMapMenu )      {        v14 = CMenu.mapScale;        v29[2 * v6 + 1] = (fradarScaleX * CMenu.mapScale * v2 + flt_68FD10 * CMenu.mapScale + CMenu.mapPos.x)                        * SLODWORD(pResolutionX)                        * fradarDiamMultiplier;        v29[2 * v6 + 2] = (CMenu.mapPos.y - flt_68FD1C * v14 - flt_68FD18 * v14 * v12)                        * SLODWORD(ResolutionX)                        * fradarUpScaleMul;      }      else      {        v15 = LODWORD(ResolutionX);        v16 = SLODWORD(pResolutionX) * fradarDiamMultiplier * fradarDiameterWRT640;        v29[2 * v6 + 1] = v2 * v16 * fradarBy2Divider + v16 * fradarBy2Divider + fradarPosX;        v17 = v15 * fradarUpScaleMul;        v2 = fradarScaleY * v17;        v29[2 * v6 + 2] = v2 * fradarBy2Divider + v15 - fradarPoxYfromBottom * v17 - v12 * v2 * fradarBy2Divider;      }      ++v6;    }    while ( v6 < 7 );    CSprite2d__SetMaskVertices(8, &v28);    RwIm2DRenderPrimitive(rwPRIMTYPETRIFAN, &vert1_x, 8);    ++v0;  }  while ( v0 < 4 );  return RwD3D8SetRenderState(25u, 5u); }

[atfburner]

wait a sec, so you have mouse free camera on bike working now Swoorup ???

[Swoorup]

Yeah, but it is just a simple workaround. What it does is: By disabling the call to find the current entity, the camera entity is always directed at the player. Since we can freely move around with the mouse on player cam, It will do the same thing on vehicle. To make a proper one, the whole CCamera: Process has to be rewritten, I believe.

OR you just can use this when in vehicle:
0159: camera_on_ped $PLAYER_ACTOR 0 2
same effect if i understand: also best in bike
