For many games, simply detecting a collision when an object hits another object is enough. That sort of collision, covered in an earlier tutorial, is great for games such as pool or mini-golf where collisions occur only when two objects physically touch each other.
But, you also have a different type of of collision. Many games today feature opponents who dodge and weave as you try to hit them. Games such as Zelda have opponents who slide and weave when you fire a slow-moving projectile such as a bow from your arrow, etc. You need some way of having your opponents be able to predict collisions from your attacks.
Being able to predict a collision and react accordingly adds some primitive level of intelligence to your targets. I will explain one simple way of predicting collisions that Flash can computationally handle:
