Top-Down RPG Shooter — Part 4 — Shooting

Welcome to Part 4 of the Top-Down RPG Shooter flash game tutorial. So far, we’ve set up the project, and added a player that moves with the arrow keys and rotates to face the mouse. In this part, we’re going to add bullets which the player can shoot by clicking and holding the mouse down.

If you find yourself confused with the basic ideas, it might be a good idea to review those tutorials. (But don’t worry, I’ll still try to explain things clearly in this post, too :-)

Step One: Creating the Bullet MovieClip

I drew mine as a black rectangle, 20px wide by 6px tall — but as always, feel free to customize your own art to fit the mood and theme of your game. Be creative! When the art is finished, select it, Convert to Symbol, and link it to a class named “Bullet”, as outlined in the following screenshot:

Step Two: Create a simple Bullet.as class
