Isometric Projection is a common game view that has been widely used for almost 30 years since the 1980s. Thanks to the good-looking 3D depth presentation in 2D coordinate, isometric projection is being used in many games in different platforms. It provides some kinds of 3D depth feeling to the game without handling full 3D coordinates and manipulations. This is an important technique in making Flash game and Flash virtual world because Flash does not support full 3D in mature way yet and isometric game view is one of the best solutions in Flash to provide 3D-like representation.
In this chapter, we are going to learn basic isometric techniques in Flash. The following topics will be discussed:
The concept of isometric projection
Drawing an isometric tile in Flash
