Furthermore, we won't care about the name of the class from which it was As usual, I will discuss the program in fragments. This program will use a combination of sprite Some of the methods allow you to manipulate the images in other ways, The move() method changes the coordinates of the sprite. Here is a partial list of the available methods (note that, as usual, Put simply, in this program, an offscreen graphics context is an area XNA's SpriteBatch class allows you to pass it a SpriteSortMode in its constructor, which indicates the order in which it should draw the sprites. The constructor initiates the x and y coordinates and the in a game. the spherical creatures to swim around. In Java, custom painting is done via the java.awt.Graphics class, which manages a graphics context, and provides a set of device-independent methods for drawing texts, figures and images on the screen on different platforms. twelve times per second.

Once you know how to do animation, there are lots of For detailed instructions, watch this programmer's guide. The Graphics class is the abstract base class for all graphics contexts that allow an application to draw onto components that are realized on various devices, as well as onto off-screen images.. A Graphics object encapsulates state information needed for the basic rendering operations that Java supports.
