Quick Tutorial #1 - Create a screen saver with Animated Sprites
Before starting this Quick Tutorial, we recommend you to read the topic below which explains in details all you need to know about screen savers: What is a Screen Saver?
A sprite is an animated or fixed object which moves or is static on screen. As the goal of a screensaver is to save screen pixels, it is better to use moving sprites (see "bouncing balls" example). The sprites can move on screen, be static, be animated (a spinning ball for example, composed of several images), bounce on the edge of the screen, collide with other sprites and more... The Sprite based screensaver is the most commonly used.
