Single Player 2. Multiplayer 3. Leaderboards 4. Achievements 5. Help and Options 6. Return to Arcade (For trial versions, there is also a 7th option, Un

When I try to run the Spacewar game, I get an error saying "NoSuitableGraphicsDeviceException was unhandled: Could not find a Direct3D device that has a Direct3D9-level driver and supports pixel shader 1.1 or great

      • This question did not get any attention when I posted it with other questions so I'll try it again by itself. Primitive Design I have built a rudimentary 3D engine using good OOD where the primitives (points, polygons, lines, etc.) provide methods for their management and transformations. If I have a model with 100,000 points, each point carries the overhead of the virtual function table and wh

      • So I'm looking at the help on Animate a Sprite. It suggests using TargetElapsedTime to set the rate the animation frames play back. Say I have an explosion that is 6 frames and I want them to play back at 4 fps. Well if I set TargetElapsedTime that slows the entire game world down to 4 fps. How do I go about keeping the Game running at the default of 60 fps but my animation running at 4 fps The o

      • I think it's neat to have DrawableGameComponents add themselves to the Game's Components collection in their own constructor - however it looks like that leads to Draw being called before Initialize on the Component. What's the intended architecture Adding Components in BeginRun works but should I still create them in LoadGraphicsContent That's an ugly splitting of things. Or do it all in Begin
