Texture Moving

Just shift the texture coordinates

you can move textures just like any object,
first, you must do that:
D3dDevice->SetTextureStageState( D3DTSS_TRANSFORMFLAGS, //some of the flags here);

then you can directly move your texture:
D3DXMATRIX trans;
D3DXMatrixTranslation( &trans, 0.0f, 0.0f, 10.0f ); // 10 along the Z- axis
-and then you cast the matrix to the textures:
D3dDevice->SetTransform( D3DTS_TEXTURE0, &trans);

just ask if you need more help

Ok, I just have one more question. What D3DTSS_TRANSFORMFLAGS flags do you use to get the textures to shift? I have been playing around with and I don''t get any errors, but the textures just will not move.

If you have a look through the DirectX docs there should
be information on how to do this. One thing to note though
is that texture transformation matrices put the offsets
into row 3 (2 in c) and not 4 (3 in c) as normal view/world
transformations.
i.e. to move a texture up by 0.5 you would need a matrix

1 0 0 0
0 1 0 0
0 0.5 1 0
0 0 0 1

you will also want to put in
D3dDevice->SetTextureStageState( 0, 3DTSS_TEXTURETRANSFORMFLAGS, D3DTTFF_COUNT2 );

To make the device transform the stage 0 texture co-ordinates and
pass them through to the rasterizer.

Hope this helps
