is it effective to use OOP in game programming?

CoderTCD · 2002-09-02T02:43:05

I want to use OOP (classes constructors destructors etc) in game programming but I''m anxcious that it could slow down the game. What do you think about it? I don''t see any OOP in game programming examples so I wish to know if anyone''s using it.

*g* Perhaps Half-Life with its unstable & ugly engine isn''t the best example to show the benefits of OOP ;-)

huh? HL is an excellent engine even if it''s out-dated, it still has the biggest mod community in the world, it wouldn''t if it was unstable and ugly.

Pretty sure that Carmack went all C++ for Q3, and is using for his current projects.

"With my feet upon the ground I lose myself between the sounds and open wide to suck it in, I feel it move across my skin. I''m reaching up and reaching out. I''m reaching for the random or what ever will bewilder me, what ever will bewilder me. And following our will and wind we may just go where no one''s been. We''ll ride the spiral to the end and may just go where no one''s been." - Maynard James Keenan [TheBlackJester ]

Quake 3 = pure Classic C.
Doom 3 = everything C++, except the main graphics engine which is still pure Classic C.

For what most people use C for, the same speed and codesize will come out from using C++. Most of the C++ standard is about improving coding habits and effeciency.

This thread could quickly become a C VS. C++ debate. I suggest at least looking at the first couple of chapters in Eckel''s "Thinking in C++ book" because it is free, very small, and easy to read. He starts off explaining C++ from a C perspective and I think it will help the original poster make his decision.

Learn OOP right and it owns classic C without classes (if your project has any kind of size that is). Also if you are working more people on a project itis MUCH easier when using OOP (define interfaces etc. and program out from them..)

OOP is just a different style of programming, it won''t affect the speed that much (at least not on today''s machines.) It just depends on your game''s design: if its poor, its performance will decrease and probability of bugs will increase. If you have a good design, then you wouldn''t notice much difference than coding it in straight C.

Probably key use of OO techniques is re-useability.
For example in my engine:

                   TGraphic (Abstract)                       |                       |                     TMesh-----------                       |            |                       |            |                   TSkinnedMesh    TProgressiveMesh

I have a "standard" TGraphic class which acquires a D3D Deice from my D3D class, and contains a VB and an IB for any graphic object. Each new level adds functionality (TSkinnedMesh uses TMeshes load routine and some other code to get skining info, but uses the exact same rendering code).

OO is not the be all and end all, but CAN (and I find IS) useful (especially if you plan on ever re-using any of your old code).
