Building Games in Flash 5 - Part 3 - Enemies and collisions

Aim: This is the third part of a series of three tutorials that cover the techniques involved in building games in Flash 5. The first two tutorials cover player movement, fire and scrolling backgrounds - if you haven't read them check them out. This tutorial will cover enemies and collisions.

Assumed Knowledge: It is assumed that you have a basic understanding of Flash and Actionscript. You should understand variables, properties, if statements and the basics of the flash 5 'dot syntax'. It is assumed that you have read tutorial 1 and tutorial 2.

By the end: at the end of this tutorial you will have built a basic flash arcade game. A simple scrolling space shooting game which could be the basis for a scramble or defender clone. The tutorial also covers functions, for loops, random numbers, scoring and hitTest.
