This long tutorial will show how we can create a fiery collision between two planets by using some Adjusment Layers and Blending Options.

We are going to make a script that will make circles collide with each other. This would be very hard to do with hitTest()’s so we are going to use a small amount of trigonometry.

This Flash tutorial will teach you about basic collusion testing.

In this tutorial I will show you how to check for collisions and how to stop the character from going outside the screen.

Pool stick changes angle according to the mouse position. Balls collide with each other, sink into holes, and roll along a tray.

In this tutorial, I will explain the second part of making a game similar to the old BreakOut game for Atari. In the previous part, we created the movement for the paddle and the ball. In this part, we will set up the bricks and apply the script for the collisions of the ball with the bricks.

Illustrating scenes from the final frontier can make for some beautiful work. In this tutorial - the longest we've ever published - I'll walk you through creating a spectacular space scene featuring two planets colliding. Strap yourselves in photoshoppers!

When creating a flash game, it’s not just the graphics that count. Gamers want to feel a part of the action. If your developing any game that requires the player to shoot at something, or involves collision detection, don’t stop reading this!

In this lesson, you will get an overview of the problem of collision detection and some common techniques, and you will learn how to use an octree to solve certain collision detection problems.

A commonly needed effect is the emission of particles at the exact location of object collision.
