The fixed // 100 Hz Update rate is convenient because it allows game logic to proceed // independantly from the refresh rate, but in some cases it's worth the extra // trouble of updating at a variable rate in order to provide smoother animation, // as in the case of a scrolling background, a shark with words written on it, // or an Arkanoid ball. // // To illustrate the aliasing problem, imagine a ball that is supposed to move // 200 pixels per second, running on a 75 Hz monitor. The update rate of the // game is 100 Hz, so that means that we will add 2 pixels to the ball position // every update, and there will be 1.33 updates per monitor refresh (on average). // That means that that 2 out of every 3 monitor refreshes will show the ball // moving 2 pixels, and and the third will show it moving 4 pixels. That isn't // smooth motion. The correct solution would be for the ball to move 2.67 // pixels every monitor refresh. But how do we do that? // // To support smooth motion, we use UpdateF. Widget::UpdateF is similar to // Widget::Update, but Widget::UpdateF gets a float passed into it that // represents how many Update's this time slice represents. In the 75 Hz // example, UpdateF would always be called with 1.33. Update has certainly // not been made obsolete, however, and you can choose which // parts of your game logic should be in Update and which should be in // UpdateF. To facilitate cooperation and good behavior between the two // update methods, there are some rules they follow: Updating always occurs // in blocks, with one or two Update calls followed immediately with an // UpdateF call. This means that the application will never get the chance // to draw or process input between an Update and a Draw without calling // UpdateF in the middle. Therefore, you can assume that focus won't be // lost, nor will input change between an Update and an UpdateF, and you'll // know that you'll have a chance to finalize your state in UpdateF so things // can be left dangling (whatever that means for your app) after Update. // You are also guaranteed that the value passed in to UpdateF will be between // 1.67 (for a 60 Hz monitor) and 1.0 (for a 100 Hz monitor). Even if the // monitor is 60 Hz but the computer is only fast enough to draw at 30 FPS // you will get two Update blocks in a row before the draw, so it will still // appear to your app as if you are updating at 60 Hz. // // IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT // // In order to fully use this, you need to set up a few things. // Set GameApp::mVSyncUpdates to true, override UpdateF(float theFrac), // and move some code from Update that used to look like // this: "mPos += 1.5;", changing it to "mPos += 1.5 * theFrac;". // Check out the C++ code for an example of motion using both Update and // UpdateF. // // IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT // // Because UpdateF is called a variable number of times per second, // you do NOT want to put game logic in it that needs to remain framerate // independant. Use UpdateF ONLY for movement related operations, and not // for your main game code. // // If you really want to avoid shearing in windowed mode, you can // set GameApp::mWaitForVSync to true and set GameApp::mSoftVSyncWait // to false. NOTE: This winds up doing some busy waiting and consumes // more processor time. // IMPORTANT: YOU MUST ALSO DELETE THE FOLLOWING REGISTRY KEY: // Whereever your registry settings are stored // (HKEY_LOCAL_MACHINE\SOFTWARE\SexyAppFramework\Demo4 for this case), // you must delete the key "WaitForVSync".
