Not Telling
I knew assembler before I knew C and C before C++. I understood pointers already thanks to assembler and curiously found the C/C++ way to approach them more convoluted because of the complex syntax. Looking at assembly output helped me understand what compilers do and get the language better.

I'm still a total noob on this topic but from what I read so far, yes, this seems to be how it works.

Do you mean even the little question mark block that you can kick out coins from have not been copyrighted? Or little turtles whose shell you can grab to throw it back at them?

I know what you're saying.
The Nvidia site seems to have suffered a hacker intrusion and I too can't find anything about physx there lately :-(

That's why I think assembler could actually be an excellent first language. After all many old programmers had nothing else and so it was their first language. I myself, though am moderately old, knew assembler before C and C++ and whenever I wasn't sure what a feature did I'd often peek at the assembler output to get it.I don't think it is so hard to learn C++ programming..
But it is sure that you should learn more about Computer before C++ programming .
You should know how the memory and cpu work together and understand what the memory address really means ....this is the key to understand pointers in C++ (notice the function pointers)
Then any trouble else with C++ programming?
If any it'll be how to design a project...
#4959810 Opengl Index buffer madness

Not sure if you nean simple geometry that you manually type the numbers for or imported geometry from a 3D program but if it's the latter then it'll already be exported with indices.how do i create an index buffer for a large mesh? i mean specifically how to i set up the array of int's from the vertex data? like what is the logic behind this? i understand what the index buffer is for and how to use it but i dont know how to set up the initial array you will pass to the gl element array buffer.
If the question is about how it works then the index is simply the location in the vertex buffer to use the data from.
Example: vertex buffer
x1,y1,z1 (position)
x2,y2,z2
x3,y3,z3
…
Then in the index buffer a triangle would be defined as [0,1,2] and another as [1,2,3] using vertex 1 and 2 twice thereby saving space and bandwidth.

I'm going to make a suggestion totally out of the blue. If you are totally new to programming try learning PHP first. It's not useful for games since it's a web scripting language but it's dirt easy and if you never programmed before then games aren't the first thing you should focus on in the first place. With PHP you will at least learn something you will encounter in most other languages such as a while loop, a for loop, switch/case, if/else etc. You will use arrays, hash tables and never have to worry about forward declarations, header files or translation units. That's for when you feel ready for the next step which is when you'd switch to C++. And PHP has the additional benefit that you will need it for your websites where you wouldn't use C++. Another language that you would learn just because it seems easier at first but overlaps with C++ might be abandoned later once you upgrade. Just my 2 cents.

I recommend the khan academy videos.
I also learned my math online from Paul dawkins's tutorials. I did calc II,II,III,DE and Lin alg.

#4958786 Did you succeed in building a game from a Game Engine?

I think it all boils down to efficient division of labour. I think I'd go a lot faster if I could develop with others who'd be my exact complement. As soon as there is competence overlap then there are going to be ego problems such as will we use my solution or yours or if my solution is always discarded because it's inferior I'd feel I'm no longer part of the team etc. However if I'm fully specialised in , say, rendering and you in game logic or physics then there's full conplementarity and no stepping on each others feet. And we could fully concentrate on a topic rather than be scared that we still have so much to sift through. So how I see it gamemaking is mostly a people management problem.

Yeah it's a matter of perspective (pun unintended)
The "cam" doesn't really exist. It's a matrix that moves whatever you want to look at into the frustum.

It's good that you bring this up because I somewhat struggled with this confusing terminology too.
Maybe there should be a term that differentiates between game-specific engine and game engine as in a very general set of libraries that can power any game with minimal code writing on your part such as Unity, a program that allows end users to make games.
My goal is to create games but with my own engine as in very specific. i.e. Other people might not be able to use it but it should serve my purposes. If it can be improved so the better.

We went from 16 colours to 16 million which is what the human eye can distinguish. We went from 2D to 3D which is what a human mind can comprehend. I suppose a 4D game in 16 billion colours wouldn't make sense. Lol

#4956318 Pointer to class type?
Posted by
on 06 July 2012 - 07:30 AM
Of course it's possible. How else would you allocate a class on the heap? When you "new" you get a pointer to your class. If it's a pointer to a base class then like another poster said the actual class would implement the different behaviour. It's how I implement gamestates but I digress.

What's so hard about pointers? They are just numbers that say where something is in memory.Alright, let me rephrase it.
I don't want to deal with pointers just yet. And even if I did, I still don't know what library to go for.
