BeginScene()

Is there something I have to call before BeginScene() in order for it work?

I changed it to this

if(SUCCEEDED(d3dDev->BeginScene()))

but for some reason it is rendering a black window

Why would it be rendering black? I am not clearing it to that color.

If you're calling Present() then perhaps black is what's on your backbuffer... why don't you clear it before BeginScene() so it has the color you want?

If you're NOT calling Prsente() then I suppose you are using a black brush on your window class creation, so it automatically paints the window in black whenever the window needs to be painted.

yes I am calling present.

here is what the game loop looks like:

//make sure the Direct3D device is valid if (d3dDev == NULL) return 0; // Clear the backbuffer to a red color d3dDev->Clear( 0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0,0,225), 1.0f, 0 ); // begin scene if(SUCCEEDED(d3dDev->BeginScene())) { // begin rendering the next scene dxMgr->beginRender("", 1); // update the scene // update each sprite for (int i=0; i < MAX_SPRITES; i++) { x = sprites.getX(); y = sprites.getY(); vx = sprites.getvelocityX(); vy = sprites.getvelocityY(); if(x > 620){sprites.setvelocityX((vx *= -1));} if(y > 460){sprites.setvelocityY((vy *= -1));} if(x < 0){sprites.setvelocityX((vx *= -1));} if(y < 0){sprites.setvelocityY((vy *= -1));} // collision detection for (int j=0; j < MAX_SPRITES; j++) { if(j != i) { if(sprites.collision(sprites[j])){ sprites.setvelocityX((vx *= -1)); sprites.setvelocityY((vy *= -1)); sprites[j].setvelocityX((vx *= -1)); sprites[j].setvelocityY((vy *= -1));} } } // update each sprites position sprites.update(); // render the sprite dxMgr->renderSprites(sprites); } //stop rendering dxMgr->endRender(); // end scene d3dDev->EndScene();

what is the code for making the scrolling code blocks?

do you have the lightning on?

check this Lighting with Direct3D and this Lights and Materials.
You could also check the SDK for this topic.

I agree with the AP (To a certain extent...). You should really take a look at some of the SDK tutorials and samples. If you don't know what ligthing is, then things will jsut go downhill from here.

As an aside, the reason BeginScrene() returned false, is that it's supposed to return D3D_OK (And it can return other things) on success, which has the value of 0, which evaluates to false. That's why you should use the SUCCEEDED() and FAILED() macros.
