Creating computer or video games, a
simple explanation.
Brains
These same steps are used to create the world or
levels the characters live in except that no motion needs to be added. Once the
character, level, and the characters motion are created we can add it all to
the game engine to get things in motion. The game engine provides the brains
for the game. They detect the input from the keyboard, mouse or joystick and
they translate it into one of the motions or actions designed previously. Game
engines also detect when a missile fired at one of the bad guys hits the bad
guy or misses and hits the wall. This is called collision detection. Game
engines also decide which way a bullet goes once it is fired, this is called game
physics.
