Re: Problem Copying SDL_Surfaces
To fix the colors, just change RGB to BGR. Windows is backwards that way. Do not know why copy isn't working - could you post more code? But anyway, I do not get why you are using SDL surfaces with OpenGL. Why do you need them? If you need an image loader, you can always use something like DevIL or ...

Re: [SOLVED] .NET vs C languages
Except that Java or C# require that C++ be faster than them. Ever notice the JVM is written in C++? Yeah, some of the JIT might make it almost the same speed, but because of the nature of a VM, C++ must execute faster than the language it's interpreting. That's not exactly true, as JIT is not inter...

Re: strange c behavior [solved, pretty sure anyways]
I think you mean heapyes, if you use the url pointer to point to some allocated memory you dont have to, just make sure that you dont over write the bounds. cause it will most likely corrupt the stack.

Re: strange c behavior
What's your compiler? Command line?
It's probably due to some strict aliasing rule. You can either disable it, or get around it with unions or gcc/intel attribute "__may__alias__"

Re: [SOLVED] .NET vs C languages
Utterly ridiculous, I wasn't going to post a reply because I at least half agree with most of your points but this is just wrong. Java/c# code becomes obsolete faster because they are proprietary. They are updated fairly regularly which can make code in previous versions unsafe eg when generics and...

Re: [SOLVED] .NET vs C languages
I'm sorry, but Java, C#, and JIT compiled languages are never going to fully replace C/++, just as C/++ will never (and cannot possibly) completely replace assembly. No, it never will fully replace. However, Java/C# are going to become the next "general purpose" language of choice, and wi...

Re: [SOLVED] .NET vs C languages
Your logic is all over the map. New languages are not faster than old languages. New languages simply accelerate development. C/C++ is only falling out of favor in corporate business setups where high level logic reigns supreme over meticulous optimization. ? I shall explain myself better. Assembly...

Re: [SOLVED] .NET vs C languages
10 years ago it was how Java was not suitable replacement for C++. Eventually, java will run faster than C++. 20 years ago it was how C++ was not suitable replacement for C. Now, C++ can run faster than C. 30 years ago it was how C was not suitable replacement for assembly. Now, C can run faster tha...

Re: Learning a porly docummented library
Read through opensource sources that use library.
You could start out reading through grrlib.

Re: Probability Question
Here is how I solved it - I am sure there is a better way. I first found probability of success incrementing or decrementing. Then I found chance of rolling 4 dice (for example, rolling 2 + and 2 -) Then I found number of times the result could be found (for example, 3+ 1- can be: +++-, ++-+, +-++, ...

Re: A polymorphism question
RTTI data is stored within a class's vtable as a pointer to an RTTI metadata object (called type_info). This metadata object must store the name of the class so at very least it is growing linearly by a byte in size with each character of the class name. IMO I don't think the few extra bytes matter...

Re: A polymorphism question
Heya GyroVorbis! I have very little experience with c++'s RTTI, and so I may be entirely wrong on the subject, but I do not understand some things you have said: First of all that typeid() grows linearly with the length of the class name. It also grows linearly with the depth of the inheritance tree...

Re: A polymorphism question
Hello Khearts. I think it is best idea to split into 2 seperate arrays. The only benefit I can see to having 1 single array is that it preserves ordering of insertion, and may be sorted. If you do not need either of these, then 2 arrays is preferred method. If you want to iterate through every objec...
