Updating and Drawing the Graphics Environment
All objects in a graphics environment undergo a cyclical process of being updated and then drawn. This occurs in the main game loop and is synchronized by a frame rate clock. Building this ability into our graphics engine and application at this point is critical for further functionality, such as physics and other interactivity, to be added down the line. Adding a strong foundation to facilitate this early on is crucial in order to succeed in graphics processing and rendering down the line.
Herein, we will examine the purpose of the main game loop and add a clock to regulate the frame rate in our project. Coordinated with this loop are updates to objects so that they can become whatever we need them to be, from audio sources to game characters. Therefore, we will also be concentrating our efforts on developing an object’s abilities.
To this end, in this chapter, we will be examining the following:
- Introducing the...
