We can divide our screen in zones according to the number of bits on eachChapter 6 - Magic KindergarteN.: Adventure Games, ADO.NET, and DirectShow variable used: 64 (8 × 8) zones with a byte, 256 (16 × 16) zones in an int16, 1024 (32 × 32) zones in anChapter 7 - Magic KindergarteN.

Using this method, if we have 15 objectsList of Figures on the screen, and only one collision, well have to do only one check against a given number of objectsList of Tables (14 in the worst case of this scenario), instead of 15 tests with 14 objects. This method has some drawbacks: We dont know which object set the bit, so we have to test all the objects looking for the collision. Some ghost objects are created when crossing the bit set for the x zone by one object with the bit set for the y zones by another object, as depicted by Figure 1-18. .NET Game Programming with DirectX 9.0 by Alexandre Santos Lobão and Ellen ISBN:1590590511 Hatton Apress © 2003 (696 pages) The authors of this text show how easy it can be to produce interesting multimedia games using Managed DirectX 9.0 and programming with Visual Basic .NET on Everett, the latest version of Microsofts Visual Studio.Table of Contents.NET Game Programming with DirectX 9.0ForewordPrefaceIntroductionChapter 1 - .Nettrix: GDI+ and Collision DetectionChapter 2 Figure 1-18: Using zone Intelligence and big objects (like the bricks), therell be lots of ghost - .Netterpillars: Artificial bits, if we have SpritesChapter 3 objects. - Managed DirectX First Steps: Direct3D Basics and DirectX vs. GDI+Chapter 4 - River Pla.Net: Tiled Game Fields, Scrolling, and DirectAudioChapter 5 - River Pla.Net II: DirectInput and Writing Text to Screen This method is most useful when we want to test a group of objects against other objects (for example,Chapter 6 - Magic KindergarteN.: Adventure Games, ADO.NET, and DirectShow bullets against enemies on screen); if we need to test all the objects against each of the others, wedChapter 7 - Magic KindergarteN.
