.Nettrix: GDI+ and Collision Detection
David Weller, Alexandre Santos Lobão, Ellen Hatton · Apress eBooks · 2004
In this chapter we introduce you to the basic concepts of GDI+, the extended library for native graphic operations on Windows systems, and discuss one of the most important aspects of game development: collision detection algorithms. Although game developers use GDI+ functions to draw images on screen, collision detection algorithms are responsible for making the drawings interact with each other. This allows a program to know when an image is over another one and to take the appropriate action, such as bouncing a ball when it hits a wall. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
