Justin Dike, lead developer and owner of CartoonSmart.com teaches every step in programming a side scrolling Flash game with Actionscript 3. Use the arrow keys to move a character around and attack while traversing a vector based environment (you can easily draw the entire level to play on using vector shapes or movie clips.

Also included is alternate code to use with a mobile device's accelerometer (tested on the Android & iPhone OS). Topics include:

• Add new classes for different enemies.
• Add new classes for objects like coins to collect.
• Swap in new art to easily create new levels (just cut and paste, or draw in new art).
• Add more levels, including animation that the player could collide with.
• Add more objectives (items to pick up or areas on the board to go to)
• Adjust how many enemies are on stage, where they spawn from, and how often they appear.
• Change the physics of the game, speed or attack intensities of the enemies

As usual with Justin's tutorials, source files are included.
