Often, when developing games, you want to write(a lot of) data, strings or numbers to a text file. This Actionscript 3 class, in combination with a small server side script (PHP in this example), allows you to do that.

If you don't know the game Angry Birds, developped by Rovio Mobile, I recommend you to open your eyes and start living. Anyway, here's how the shooting system works!

For a lot of people the world of 3D is a scary one. Working in Flash with two dimensions (x and y) is hard enough, you can say. But adding a third dimension (z) is a lot of fun. Let's make a little interactive 3D car, with help of PaperVision3D.

When you're making games in Flash, you'll always reach a point where you want your enemies or bullets to move towards a certain destination: homing objects. Learn how to move objects towards a certain (moving) destination.

If you have two objects in a coordinate space, such as two movieclips in your Flash movie, you can preform a lot of tasks with some simple math. You can let the objects move towards each other for example. Here are the theoretical basics for doing that.

Part three of creating a game like Battle Garegga. The only thing remaining to look at is the enter frame handler, the function that handles everything that is going on in our game. It's a big one. Let's check it out.

Part two of creating a game like Battle Garegga. In the first part we looked at the properties, constructor, key handlers and the mouse move handler of the game class. Let's have a look at the - more complicated - rest!

Shoot 'm up arcade games like Battle Gargegga, Spacewar!, Space Invaders, Ikaruga and DoDonPachi have been popular for ages. Controlling an aircraft in topview and shooting a lot of enemies is basicly the description of them. But how to make such games?

When you throw a dart arrow in the real world (or shoot a rocket) it's point will always hit the ground first. In other words, the arrow always rotates towards the ground (head first) during his flight. It's easy to simulate this in Actionscript. Let's start rotating.

Trigonometry is the branch of mathematics that studies triangles. In Flash games, and programming Flash games in Actionscript, it's essential to have knowledge about trigonometry. The basics are explained here, step by step!

Shooting bullets or other objects is an important gameplay element in internets most succesful games. If it comes to firing bullets, there's a lot of possibilities. Let's talk about the basics first.

A lot of people wonder how they can create some kind of random fireworks (or: explosion) when they click the mouse button in a movie, at the position of the mouse cursor. This is how you do it!

In this serie of tutorials we're gonna show you how to create a 2D side scrolling game (such as the famous Mario World for example). We start by creating a background that slides if we walk to the left or right with our hero: the slide effect.

It's nice that objects move. But wouldn't it be nicer if we can control the movement of an object? If we can interact with it? Let's use Flashs KeyboardEvent to control the movement of an object with some keys.

Moving objects on planet earth don't move forever. They will be stopped by some force, one way or another. If a ball rolls on a flat surface, it will stop because of it's friction with that surface. Let's check that out.

If an object hits a surface you can choose to handle this collision in many ways. One of the options is to make the object bounce, as a tennis ball would do for example. Get to know everything you need to know about bouncing.

In real life moving objects fall down towards the surface of the earth. Due to gravity, as you know. Adding the force "gravity" to moving objects in a Flash movie is not that hard of a job.

Making objects move (such as MovieClips) is nice, but at some point they need to hit some things. Walls for example. Sounds difficult, but it's not. Let me try to show you.

If you want to move an object with Actionscript you basically adjust it's position (x and y values) every frame. This tutorial will let you move a MovieClip to the right, with a certain steady speed.
