If you are going to start C++ this is a great sourced http://www.cplusplus.com/ .  I personally am a mathematician, and I got majority of my heavy programming from this source.  Do not be discouraged by the language.  It is very powerful and is great for object oriented programming which is a very big thing now a days.

The above link has great tutorials and also reference guides.  This will not only allow you to know how to use the coding syntax, but understanding what is going on behind some of the functions or code within the library.  It will be a big help when you start to manipulate data more.

Thanks for the advice.

I only want OpenGL to do rendering, but SDL to control sound and events.

That doesn't make much sense, what do you need GLUT then for? You can do the same OpenGL stuff with SDL, so why not just use it?


SDL and glut conflicts, since they like to control the same things.

Exactly! It do the same thing. You have to chose one and use it... If you want to use glut so just find another one sound handler ie OpenAL.


That's very true. I wanted to explore the functionality of both, but for now I will only use SDL. I think SDL provides a more straight forward approach. I haven't been able to find a really good tutorial for OpenAL for beginners. I'm going to adjust the code later and see what you guys think about it. I am going to use only SDL in the first case. Also any advice on whether I should use SDL or glut/OpenAL? Which would be more practical for creating an rpg game?

Here are the windows that I am getting. I have attached them a a file. I only want the opengl window, but I don't need the SDL App window to come up. The big issue is will I have to put my OpenGL rendering within the while(running = true) loop to just get it to render with the sound? I only want OpenGL to do rendering, but SDL to control sound and events. Is that possible? Currently the only thing that I want from SDL is Audio, but it wants to control video or a screen as well, even though I only use SDL_Init(SDL_INIT_AUDIO).

I have already actually tried inputing SDL_SetVideoMode(640,480,32,SDL_OPENGL). SDL still wants to render a screen if I want to control my sound effect events.

Here is the adjusted code for the main section of the program. I decided to move the sound function into the main program. There may be a better way of doing this though.

SDL and glut conflicts, since they like to control the same things. Basically here SDL events can not even be controlled at all unless you first do SDL_SetVideoMode().

I am having a similar issue too. I am wondering how to get opengl to do all my rendering and use sdl for sound, but for some reason sdl wants to take over. Have you figured out how to do that?
