Collision detection is a means of determining whether two objects have come into contact with one another. In games, this is necessary in order to make decisions. For example, in a Fighting game, it is important to know whether a character's punch has hit or missed an opponent.
If the two objects intersect, meaning that they are in the same place at the same time, they are assumed to have made contact. In the Fighting game, if one character's fist and the other character's face are in the same place at the same time, someone has a bloody nose!
