GenerateTexture function

[Azorbix]

Simply you give it the rendering device, a texture interface, and a specified colour and it will generate a single coloured texture for you.



HRESULT GenerateTexture(IDirect3DDevice9 *pD3Ddev, IDirect3DTexture9 **ppD3Dtex, DWORD colour32)
{
if( FAILED(pD3Ddev->CreateTexture(8, 8, 1, 0, D3DFMT_A4R4G4B4, D3DPOOL_MANAGED, ppD3Dtex, NULL)) )
return E_FAIL;

WORD colour16 = ((WORD)((colour32>>28)&0xF)<<12)
|(WORD)(((colour32>>20)&0xF)<<8)
|(WORD)(((colour32>>12)&0xF)<<4)
|(WORD)(((colour32>>4)&0xF)<<0);

D3DLOCKED_RECT d3dlr;
(*ppD3Dtex)->LockRect(0, &d3dlr, 0, 0);
WORD *pDst16 = (WORD*)d3dlr.pBits;

for(int xy=0; xy < 8*8; xy++)
*pDst16++ = colour16;

(*ppD3Dtex)->UnlockRect(0);

return S_OK;
}


usage:
GenerateTexture(g_pD3Ddev, &g_pD3Dtexture, D3DCOLOR_ARGB(255, 0, 168, 255));

Dawg thats the shit thanks :banana: i am use this for sure, save me lot of time :laugh:

[qs2]

thanks Azo, this saves me a large chunk of filesize.. had the problem mentioned here - http://forum.game-deception.com/showthread.php?t=7272

for those interested (or lazy maybe:laugh: ) - d3d8 CreateTexture takes one less parameter than d3d9's, so here's the d3d8 version of Azorbix's code:
HRESULT GenerateTexture(IDirect3DDevice8 *pD3Ddev, IDirect3DTexture8 **ppD3Dtex, DWORD colour32)
{
if( FAILED(pD3Ddev->CreateTexture(8, 8, 1, 0, D3DFMT_A4R4G4B4, D3DPOOL_MANAGED, ppD3Dtex)) )
return E_FAIL;

WORD colour16 = ((WORD)((colour32>>28)&0xF)<<12)
|(WORD)(((colour32>>20)&0xF)<<8)
|(WORD)(((colour32>>12)&0xF)<<4)
|(WORD)(((colour32>>4)&0xF)<<0);

D3DLOCKED_RECT d3dlr;
(*ppD3Dtex)->LockRect(0, &d3dlr, 0, 0);
WORD *pDst16 = (WORD*)d3dlr.pBits;

for(int xy=0; xy < 8*8; xy++)
*pDst16++ = colour16;

(*ppD3Dtex)->UnlockRect(0);

return S_OK;
}

Thanks Alot Azorbix this REALLY helps. :ditsy:

edit: solved, gj, im an idiot.

cool, useful for chams :-) ty.
Beats using D3DXCreateTextureFromFileInMemory.

Just wanted to let you guys know that this has helped me a lot.

Thanks :)

Here's for masm32:


CreateColoredTexture proc pd3dDevice:DWORD, ppTexture:DWORD, color:DWORD

LOCAL LockedRect:D3DLOCKED_RECT


push ebx

mov ebx, ppTexture
ICall pd3dDevice::IDirect3DDevice9.CreateTexture, 1, 1, 0, 0, D3DFMT_A8R8G8B8, D3DPOOL_MANAGED, ebx, NULL
mov ebx, [ebx]
ICall ebx::IDirect3DTexture9.LockRect, 0, ADDR LockedRect, NULL, 0
mov eax, color
mov ecx, LockedRect.pBits
mov [ecx], eax
ICall ebx::IDirect3DTexture9.UnlockRect, 0

pop ebx

ret

CreateColoredTexture endp


I haven't tested it but it should work; remember, you need ObjAsm32.

I still dont understand shi*t of asm :\

but Gj on the c++ one azorbix!!

Sorry to bump such an old thread, but I keep getting D3DERR_INVALIDCALL from CreateTexture. Any ideas?

Game is CSS btw.
