An engine is just like what it sounds. It's a driving force. The game is just like a big big big big big car, so it needs multiple engines. A big car needs an engine for each wheel, and windows, and air conditioning etc. So a game needs an engine for its graphics, and movement, and enemys, and battles, and menu etc.

Another way to think of it is like a big function. You type it once, then hand it parameters, and then just have it called a lot. Its like what drives your game almost.

The only way to prevent all lag in a game is not to make the game.

An engine is the core to a game. It contains all the functions to AI, rendering, physics and so on. Kinda of like DB.

I found an article that might help you, or confuse you heh.

http://www.gamasutra.com/php-bin/letter_display.php?letter_id=114

My best definition of a game engine is like what CompuWiz said, it is the driving force. The way the graphics are displayed, how the characters move, interaction, environments, cinematics, and so forth...

An example: The Quake engine is widely used. Take the games Quake III and Soldier of Fortune II. SoF II used the Quake engine. So if you have ever played those games you can see the similarities among them. Although, I am sure they tweaked the Quake engine a bit...

I am the very disease you pretend to be.

just to get it strait....
An engine is a set of parameters and rule for a game?
sorry to bother you again...

Ok, for example....

A car has an engine (well most do) right? Could it function without the engine? The engine in a car regulates and tells the rest of the car what to do right?

Ok, well in a game's case, the engine is made up of code, instead of car parts heh.

You could say it is parameters or a set of rules for a game, but it is more than just that. It is not just one thing, it has many parts.

It is the way the graphics are displayed, how the menus work, the ai, the level system, the physics, and etc.

Depending on what kind of game you make your engine would need different things. Say, for instance, that you wanted to build a FPS (first person shooter).

This engine would need code for...
1.) Movement(straffing, climbing, crouching)
2.) Shooting/Explosion (there is the physiscs)
3.) Enemy AI
4.) Taking damage (self/enemies)
5.) A menu layout (options, items, inventory)

This is coming from the top of my head right now heh, I'm sure I missed a few things. If you need anymore help, email me: epidemicz@myrealbox.com
