what makes a game engine?
Author
i have been learning openGL for a little while now, going through the awesome NeHe tutorials, and i would like to have a go at writing a simple game engine, with model loading, terrain, lighting and input but am not really sure how to start or how they are structured. i am using C++ and to me i would make classes for different things like:
*main class (for initialisation and msg handling)
*model class
*terrain class
*texture class
*etc..
if i had all these classes to use then wouldnt this just be a library of classes, or is that what an engine is?
Also what is the difference (if any!) between a game engine and a graphics engine!?
any help would be appreciated
thanx

a ganme engine must also have a function that manage the memory.
That means that you can allocate memory and release it, if you don''t need this memory.

Like new and delete for instance?

it would also have to have collision detection and that kind of stuff.
and popcorn. Game engines need popcorn. popcorn is good.

Physics. Functions for moving objects around in a realistic (or non-realistic) way. Collision detection is part of that.
Can you please send me your popcorn code? I always get the error:
Error 854735835234.5235253b: Not enough corn available
I have no idea how to fix it... maybe buy some extra memory? Or is there a popcorn API available which fixes this?
hmmmmmm a good idea for a game
sim popcorn
KING CLAUDIUS Now, Hamlet, where''s Polonius?
HAMLET At supper.
KING CLAUDIUS At supper! where?
HAMLET Not where he eats, but where he is eaten

Don''t forget to use glPushCorn(num_of_kernels); and glPopCorn(num_of_kernels). If ou dont push the number of kernels on, it wont know how many to pop, in which case you get the error of it not knowing how much corn there is to pop.
