Robotron AS 2.0 – Part 1

{loadposition adposition4}

Overview –  Robotron

The type of game we are going to try and make with Flash is a real-time action game. In a real-time action game, the game clock or game time, flows continuously until the game is over. The opposite of a real-time game is a turn-based game where players take discrete turns and the game action is paused between turns. Most real-time games are action games, role-playing, and shooter games.

Robotron: 2084 was one of my favorite arcade games when I was a kid, and I can remember playing it along with Pac-Man at the Sun Bee liquour store on Sunset Blvd, in West Hollywood. Robotron is a good example of a real-time action game. Robotron is a 2D action game where the hero character must advance through multiple levels of increasing difficulty fighting robots and saving humans. To see a quick video of the game in action go here: 

It is impossible to make a web-based game with Flash, that has the same feel and game-play as the original arcade game classics. Probably the most important aspect of Robotron, which cannot be successfully emulated with a mouse and keyboard, was the dual joysticks used to move the hero and shoot lasers. It is amazing to consider how much was accomplished with so little RAM and processing power in the classic arcade game era. Of course games like Roboron were programmed in assembly and took direct control of computer hardware and graphics.

To start our Robotron game we are going to need to make some pixel-art characters called "sprites." Undoubtedly you should be creative as possible with your graphics and sprites, but I also recommend you keep them as simple as possible. Watch my videos on creating pixel art characters with Photoshop:
