Sprite Draw order
Author
Ok, i have 2 sprites, one covers the entire screen and one is small. When i call draw, i'm calling "order_fronttoback" the sprite that covers the screen is at 1.0f and the other is at 0.0f, but i only see the bigger one... when i don't draw it, then i see the smaller one, so i know both are being drawn but for some reason the bigger one is one TOP of the smaller one... even though i have the "order_fronttoback" flag triggered...

ok, i just enabled depth buffer... wasn't there b4 (ha..) but now whenever i try to clear the screen with "targetzbuffer" it fails.. y's this?

// init code
m_pD3dDeviceCOM->SetRenderState( D3DRS_ZENABLE, m_bZBuffer);
// frame code
m_pD3dDeviceCOM->Clear(0, NULL, D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER, 0, 1.0f, 0)
the Clear function is what breaks the program
m_pD3dDeviceCOM->SetRenderState( D3DRS_ZENABLE, m_bZBuffer);
// frame code
m_pD3dDeviceCOM->Clear(0, NULL, D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER, 0, 1.0f, 0)

Are you setting the EnableAutoDepthStencil member of your presentation parameters to true and chosing a depth format?

ohhhh, i thought the depth stencil was for stencilling not the Zbuffer.. and what's the format for? like A8R8G8B8?
Edit: nv/md, i found the right format: "D3DFMT_D16"

wow... ok, it works know, BUT the bigger texture isn't drawing... what should i clear the screen with?
Clear(0, NULL, D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER, 0, 0.0f, 0)
or
Clear(0, NULL, D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER, 0, 1.0f, 0)
or what?
i'm using all sprites (it's a 2D game) so all my Z's are between 0.0f and 1.0f
Clear(0, NULL, D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER, 0, 0.0f, 0)
or
Clear(0, NULL, D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER, 0, 1.0f, 0)

also, does this matter? instead of doing Draw(pTex, pRect, pCenter, pPos, Color)
pPos is NULL. the way i'm moving the sprites is by storing the XYZ coordinates in floats, then having a transform matrix and SetTransform()'ing the sprite, then drawing it with a NULL pointer to the position.. does that matter?
