Hello, Sorry i'm a bit new to directx. I followed a tutorial about how to draw sprites to the screen which i found useful. But i can't seem to work out how to translate a sprite using the same matrix as i use for every other translation. E.g. if i translate a box by 10 and the sprite by 10, they do not end up in the same place. Below is the code i use at the moment. D3DXVECTOR3 vCenter( 0.0f, 0.0f, 0.0f ); D3DXVECTOR3 vPosition( 10.0f, 0.0f, 0.0f ); g_pSprite->Begin( D3DXSPRITE_ALPHABLEND ); g_pSprite->Draw( g_pTexture,&srcRect,&vCenter,&vPosition, D3DCOLOR_COLORVALUE(1.0f,1.0f,1.0f,1.0f) ); Any help is most appreciated :)

use g_pSprite->SetTransform( D3DXMatrix ). You can make multiple calls inbetween Draw()'s to draw multiple sprites.

For example:


g_pSprite->Begin( D3DXSPRITE_ALPHABLEND );

g_pSprite->SetTransform( someMatrix );
g_pSprite->Draw( g_pTexture,&srcRect,&vCenter,&vPosition, D3DCOLOR_COLORVALUE(1.0f,1.0f,1.0f,1.0f) );

g_pSprite->SetTransform( anotherMatrix );
g_pSprite->Draw( g_pTexture,&srcRect,&vCenter,&vPosition, D3DCOLOR_COLORVALUE(1.0f,1.0f,1.0f,1.0f) );

g_pSprite->End();



For 'someMatrix' you may want to generate it using D3DXMatrixTransformation().
