I have a very stupid question, i'm new to hacking, what is the php code for?
Sorry again for my noobism

Paste into notepad and save as .exe
Or you could learn c++

Great posts.

It is not PHP scripting, it is the C++ programming language displayed using the forums PHP tag for syntax highlighting. And if you can not work out what it is for, then it is of no use to you at this moment in time.

[adeexd]

so, it's not a final release, it's like an open work in progress?

It's source code for people who know how to use it...

this is for steam version, current

all credits to mattdog btw, since its painfully obvious how to make your own based on his posts....very simple (scolding you secret pmer!!)

Just some example esp

      } 


looks like d3dxVec3Project if

_ESI + 0x50 or v49 is View*proj*world dunno if MatrixFunction_001 is matrixmultiply and 0x273B4 & 0x273B8 are pviewport->Width & Height


if not its using stated below




D3DXVec3Transform almost looks as similar as what mattdog posted i think.

Think this all matts doing havent tested it also anyone know why the check on w? I know for D3DXVec3TransformCoord what w would be dived into xyz why i was think it was vec3project since in ur calc and in function you divide by w but i dunno im tired lol and havent gotten to test it cuz my comp doesnt like bfbc2 :/

::D3DXVec3Transform(&Vector4D,&Origin,&m_Screen);
	
	
	if(Vector4D.w < 0.0001f)
		return FALSE;

	

	out->x = CX + CX * Vector4D.x / Vector4D.w;
	out->y = CY - CY * Vector4D.y / Vector4D.w;

	return TRUE;

If you dont mind post a sig to this function so i can look at it further currently still working on vertexshader math(matrix algebra) and would love to look at this thnx

[fatboy88]

k i just tested it finally, works fine same shit as mattdoggy dog posted just less lines and easier to look at

credz to mattdoggy dog

D3DXVec3Transform(&Vector4D,&Vector3D,&m_Render->Ptr->screen);
if(Vector4D.w > 0.0001f){ 
	 Vector2D.x = CX + CX  * Vector4D.x/Vector4D.w;
	 Vector2D.y = CY - CY  * Vector4D.y/Vector4D.w;

[fatboy88]

gah 3 post in a row but soz i had to get it right :P


what that w2s is doing s0b

 
               ::D3DXVec3TransformCoord(&Vector3D,&player->vec,&m_Render->Ptr->screen);
				
		Vector2D.x =	 Viewport.X +  ( 1.0f + Vector3D.x ) * Viewport.Width / 2.0f;
                Vector2D.y =     Viewport.Y +  ( 1.0f - Vector3D.y ) * Viewport.Height / 2.0f;

now to get the real usage im going for from this world*view*proj matrix mattdog found :3

Hey silverfish..

I was wondering if you could post What g_pGameRender->RenderData->WorldTransform is?
Like what class is g_pGameRender? CRenderer? and RenderData? and What is world transform and where are the pointers to RenderData and WorldTransform in the classes?

The only thing Iv got problems with is the W2S

it wasnt about that it was recreating this

I knew it was ve3project.

i am wondering why there isn´t a public external box esp for bc2?
the problem with aero is solved, no prob at all to bypass the overlay.

[Auto Merged - 3:30:10 UTC]

Hey, great job on this code man!

I have a question though, whats up with this:

FLOAT w = m_Screen.m [0][3] * Origin.x +
m_Screen.m [1][3] * Origin.y +
m_Screen.m [2][3] * Origin.z +
m_Screen.m [3][3];

if(w < 0.0001f)
return FALSE;

in my matrix m_Screen.m [0][3] means column 3 and row 0, however column 3 contains the w coordinates which are always 0, so the w2s returns all the time.

0 0 0 w <---- m_Screen.m[0][3] = w = 0
0 0 0 w <---- m_Screen.m[1][3] = w = 0
0 0 0 w <---- m_Screen.m[2][3] = w = 0
0 0 0 w <---- m_Screen.m[3][3] = w = 0

What am I missing here?


I have also tried using the function fatboy posted:

bool ESP::worldToScreen(D3DXVECTOR3* target, D3DXVECTOR4* out)
{
    float CX = RENDERER->m_virtualWidth/2.0f;
    float CY = RENDERER->m_virtualHeight/2.0f;

    D3DXVec3Transform(out, target, &(WORLDRENDER->m_render->m_matrix));
    if(out->w < 0.0001f)
        return false;

    out->x = CX + CX  * out->x/out->w;
    out->y = CY - CY  * out->y/out->w;

    return true;
}

function call:

        D3DXVECTOR3 pos = *(D3DXVECTOR3*)&target->m_controlledControllable->m_worldTransform->m_transform.trans;

        D3DXVECTOR4 coords;

        worldToScreen(&D3DXVECTOR3(pos.x, pos.z, pos.y), &coords);

Calling this function just prints the esp in the wrong positions near the top left corner of the screen.

Any help will be appreciated!

is that the viewProjection matrix? if not use viewprojection or multiply view matrix by the projection
