D3DXMatrixTranspose(&ProjMatrix, &ProjMatrix);

D3DXVec3Project(&VectorMiddle, &pModel->Position3D, &Viewport, &ProjMatrix, &ViewMatrix, &WorldMatrix);

if (VectorMiddle.z < 1.0f && ProjMatrix._44 < 1.0f) //not sure

	pModel->Position2D.y = VectorMiddle.y;
}

I don't see any boxes now, am I missing something? :P

Code:

void Worldtoscreen(LPDIRECT3DDEVICE9 Device)
{
	ModelInfo_t* pModel = new ModelInfo_t;

	D3DXMATRIX ProjMatrix, ViewMatrix, WorldMatrix;
	D3DXVECTOR3 VectorMiddle(0, 0, 0), ScreenMiddle(0, 0, 0);

	Device->GetVertexShaderConstantF(204, ProjMatrix, 4); 
	Device->GetVertexShaderConstantF(223, ViewMatrix, 4); 

	D3DXMatrixIdentity(&WorldMatrix);
	D3DXMatrixTranspose(&ViewMatrix, &ViewMatrix);
	D3DXMatrixTranspose(&ProjMatrix, &ProjMatrix);

	D3DXVec3Project(&VectorMiddle, &pModel->Position3D, &Viewport, &ProjMatrix, &ViewMatrix, &WorldMatrix);

can't test but remove this line "if (VectorMiddle.z < 1.0f && ProjMatrix._44 < 1.0f)" and look if it works. If not, you have to log the shader and look whether or not this changed:
// cbSharedPerView c204 4
// cbPerObject c223 4

I don't know how to log the shader. Is it bad if I use stride and set texture? I had problems with set pixel shader, models would become transparent in heroes and generals, and I dont know to make them work

Stride and SetTexture(1.. worked for me, pixel shader was buggy. To log the shader use this:

Code:

void doDisassembleShader(LPDIRECT3DDEVICE9 pDevice,char* FileName)
{
    std::ofstream oLogFile(FileName,std::ios::trunc);
    if (!oLogFile.is_open())
        return;
    IDirect3DVertexShader9* pShader;
    pDevice->GetVertexShader(&pShader);
    UINT pSizeOfData;
    pShader->GetFunction(NULL,&pSizeOfData);
    BYTE* pData = new BYTE[pSizeOfData];
    pShader->GetFunction(pData,&pSizeOfData);
    LPD3DXBUFFER bOut;
    D3DXDisassembleShader(reinterpret_cast<DWORD*>(pData),NULL,NULL,&bOut);
    oLogFile << static_cast<char*>(bOut->GetBufferPointer()) << std::endl;
    oLogFile.close();
    delete[] pData;
    pShader->Release();
}

in drawindexedp:

if(Stride == 40)
if (GetAsyncKeyState(VK_F9) & 1)
	doDisassembleShader(pDevice, "shader1.txt");
or
if (GetAsyncKeyState(VK_F10) & 1)
if(Stride == 40)
	doDisassembleShader(pDevice, "shader2.txt");

Looks similar to what I logged two patches ago, so worldtoscreen should work. I left out GetViewport maybe that's the problem?

Code:

..
Device->GetViewport(&Viewport);
Device->GetVertexShaderConstantF(204, ProjMatrix, 4); 
Device->GetVertexShaderConstantF(223, ViewMatrix, 4); 
..

Works :P puu.sh/hjnd7/c3444eb5e3.jpg Aiming at feet, but I guess I'll find the head chams, or body chams. Or maybe just fix the Y coord where the mouse goes.

Thanks for your source, your time, and the will to help some random guy

Code:

void Worldtoscreen(LPDIRECT3DDEVICE9 Device)
{
	ModelInfo_t* pModel = new ModelInfo_t;

	D3DXMATRIX ProjMatrix, ViewMatrix, WorldMatrix;
	D3DXVECTOR3 VectorMiddle(0, 0, 0), ScreenMiddle(0, 0, 0);

	Device->GetViewport(&Viewport);
	Device->GetVertexShaderConstantF(204, ProjMatrix, 4); 
	Device->GetVertexShaderConstantF(223, ViewMatrix, 4); 

	D3DXMatrixIdentity(&WorldMatrix);
	D3DXMatrixTranspose(&ViewMatrix, &ViewMatrix);
	D3DXMatrixTranspose(&ProjMatrix, &ProjMatrix);

	D3DXVec3Project(&VectorMiddle, &pModel->Position3D, &Viewport, &ProjMatrix, &ViewMatrix, &WorldMatrix);

// 	if (VectorMiddle.z < 1.0f && ProjMatrix._44 < 1.0f) //not sure
// 	{
		pModel->Position2D.x = VectorMiddle.x;
		pModel->Position2D.y = VectorMiddle.y;
	//}
	ModelInfo.push_back(pModel);
}

Glad it works, I think you can adjust height if you edit the last value of ScreenMiddle or pModel->Position3D somehow, try this:

Code:

..
D3DXVECTOR3 VectorMiddle(0, 0, 0), ScreenMiddle(0, 0, (float)aimheight);
pModel->Position3D = ScreenMiddle;
..

**ves23** · 04-19-2015

Even if I use the head only chams, its still drawing a box, aiming at the feet. Why is that?

**ves23** · 04-20-2015

All's working good now. Thanks once again.

Hey I can use this W2S? too.

Code:

bool WorldToScreen(D3DXVECTOR3 inpos, D3DXVECTOR3 &outpos, LPDIRECT3DDEVICE9 pDevice) { DWORD dwRenderData = (DWORD)GetModuleHandleA("i3GfxDx.dll") + 00000; CRenderData* RenderData = (CRenderData*)(dwRenderData); D3DXVECTOR3 vScreen; D3DVIEWPORT9 g_ViewPort; pDevice->GetViewport(&g_ViewPort); g_ViewPort.X = g_ViewPort.Y = 0; g_ViewPort.MinZ = 0; g_ViewPort.MaxZ = 1; D3DXVec3Project(&vScreen, &inpos, &g_ViewPort, &RenderData->RenderData->ProjectMatrix, &RenderData->RenderData->ViewMatrix, &RenderData->RenderData->WorldMatrix); if (vScreen.z < 1.0f && vScreen.x > 0.0f && vScreen.y > 0.0f && vScreen.x < g_ViewPort.Width && vScreen.y < g_ViewPort.Height) { outpos.x = vScreen.x; outpos.y = vScreen.y; outpos.z = vScreen.z; return true; } return false; }

	CRenderData* RenderData = (CRenderData*)(dwRenderData);
..

which game pointblank? if you have the classes and the right offset then yes

**ves23** · 04-25-2015

Ivous, I require your help again, doing it now for a different game, UE3 Engine.

Logged this

Code:

//   ViewProjecti********  c0       4
//   CameraPosition       c4       1
//   BoneMatrices         c5     225
//   LocalToWorld         c230     4
//   WorldToLocal         c234     3

Which one am I supposed to use? I've tried them all, if I use 4, it kinda works, rotating my screen moves the boxes, but they're all in the middle of my screen

Code:

Device->GetVertexShaderConstantF(0, ProjMatrix, 4); 
Device->GetVertexShaderConstantF(4, ViewMatrix, 4);

I can make videos, if needed

use viewprojection & localtoworld

Code:

Device->GetVertexShaderConstantF(0, ProjMatrix, 4);
Device->GetVertexShaderConstantF(230, ViewMatrix, 4);

D3DXMatrixIdentity(&WorldMatrix);
D3DXVec3Project..

Using viewprojection & localtoworld, no boxes are being drawn, heres the full shader log pastebin.com/1m39x6a5
