Thread: Where To Start?

I was under the impression -- possibly mistaken -- that you had to use C# if you wanted to use XNA.

Put short, I can do as much as draw a few polygons, translate them, translate "yourself" in the dimension, and uh... yeah, basically, no idea how to even render nets, spheres, complex entities, what Anti-Aliasing is etc etc.

Wikipedia is your friend, for some questions anyway. http://en.wikipedia.org/wiki/Anti-aliasing

As for your other questions . . . I don't know, maybe you should read some books or web pages on graphics theory.

There are some things you cant fully understand and know until you have tried it, failed it, and done it. And programming games is one of those things. I suggest you check what simple 2D games (no dont start with 3D yet) use.

Take animation for instance, how would you animate something. Well what is an animation really? What you do when you animate something is you have frames where you slowly change something and then replay them fast enough so the brain interprets it as something continues right?

Ok so you know you need to switch frames. Now what is a frame? Easiest to think of a frame in an animation is a picture, and a picture in a graphic api can be represented with a texture. So you now know that you need to switch textures fast enough, so how can that be done in code with OpenGL? Well from NeHe tutorial you know how to load a single texture, so load up several and come up with a system where you switch which texture is being used after a given time.

This is how i usually think when i program, and especially when i program games. I basicly just think like this:
What do i want done?
Ok what steps are there?
How do i translate this to the world of C/C++ and OpenGL?

And after that I try to find how to implement it.

You come to a point where tutorials wont help you much further and where actual trial and error is needed. My suggestion is you try to do a basic 2D game with animations. Maybe something as simple as a board-game of some sort. When that is done try do animations and so on. And if you ever get stuck see if you cant solve the problem with the steps up here. And if no solution is found, you can always ask for tips here at cboard , we are usually more than happy to give tips and pointers and such, as long as you show some will to try to find the solution yourself.

Hope this helps.

Get yourself a decent book on your API of choice as well. There should be a few threads around on that if you do a search.

The thing with tutorials, as you said, is they demonstrate how to do one particular thing, generally without much regard to if it's the "best" way to do it. Careful not to get yourself in the trap of trying to do everything exactly like a tutorial, or trying to stitch tutorial code together into an entirely usable application...the results tend to be ugly at best, IMO.

You do. Therefore, not a good choice .

Well, especially if you don't know C#.

I think you probably would be best off dealing with 2D graphics for now. At least that's how most people learn it, I think.
