D3D EndScene Hook dont work
D3D EndScene Hook dont work
Hey, this is the source of purple.d1amonds d3d9 Hook Tutorial.
I inject the .dll in the wow process, but nothing happend. Can anyone say me where the error is please ? The .dll is successfully loading, i have test it with a messagebox.
Thanks

Just a guess, could be other errors as well:
Maybe it hasnt loaded when you inject. Try:
Code:
hModule = GetModuleHandleA("d3d9.dll");
Code:
while(!hModule){
hModule = GetModuleHandleA("d3d9.dll");
}
Thanks for answer, but the .dll loaded successfully , i tried it with a messagebox at the end of the InitHook function 
.
Regards
.Regards
is it possible that wow don´t use d3d9 ? It whoud be nice if anyone of you can test it with another game 
offtopic: Where is the Edit button ?! ;D

You're not drawing the rect
you confuse me , how do you mean this ? I draw the rect in the hooked endscene funktion:
Code:
bool hkEndScene(LPDIRECT3DDEVICE9 pDevice){
const D3DCOLOR txtPink = D3DCOLOR_ARGB(255,255, 0, 255);
DrawRect( pDevice, 10, 10, 200, 200, txtPink);
return pEndScene(pDevice);
}
Regards

return pEndScene(pDevice);
}

Code:
void DrawRect(LPDIRECT3DDEVICE9 Device_t, int X, int Y, int L, int H, D3DCOLOR color)
{
D3DRECT rect = {X,Y,X+L,Y+H};
}
Here's are DrawRect and DrawFilledRect that I use(written from memory, i'll check for you later)
Code:
ID3DXLine *pLine = NULL;
void DrawRect(int X, int Y, int Width, int Height, D3DCOLOR col)
{
D3DXVECTOR2 rect[5] = { {X, Y}, {X+Width, Y}, {X+Width, Y+Height}, {X, Y+Height}, {X, Y}};
pLine->Begin();
pLine->Draw(rect, 5, col);
pLine->End();
}
void DrawFilledRect(int X, int Y, int Width, int Height, D3DCOLOR col)
{
D3DXVECTOR2 rect[2] = { {X+Width/2, Y}, {X+Width/2, Y+Height} };
pLine->SetWidth((float)Width);
pLine->Begin();
pLine->Draw(rect, 2, col);
pLine->End();
pLine->SetWidth(1.0f);
}
void InitializeD3DCrap(void)
{
D3DXCreateLine( pDevice, &pLine );
pLine->SetWidth(1.0f);
pLine->SetPattern(0xFFFFFFFF); //solid line
pLine->SetAntialias(false); //increases speed
pLine->SetGLLines(true); //increases speed
}

.Ahhh damn ok i understand
Okay hmm but why is this don´t work:
I think the messagebox must be pop up. but it dont work :-/...
