[quote][b]Posted by:[/b] jbSPINE video games? you have to walk before you can run, do you have any idea how complicated a video game is?. and the GUI is the heart and soul of a program, thats like saying you have learned to drive, but your still not sure about the steering wheel, use the books you have, read them again, then do what all good programmers do: learn another code, then another, then another, build yourself a huge arsenal, I personaly prefer Python, the GUI is pretty straight forward, dont think your impressing anyone with C++, your programs are going to be so unstable, even the Michael Jackson defence team wouldnt build their case on it, but if your determined, do a google for "C++ GUI tutorial",,, Good Luck, dont crash your PC, [/quote] I plan on having a GUI in dos before I finish with the program but have you seen a GUI in dos? They suck. In dos a GUI isn't the heart of your program. The heart of this program is turning out to be the functions that compute the gravitational forces between the objects. What I have created so far has been pretty stable, but I am having a probelm passing large numbers into functions even though the number is less than the MAX_DOUBLE. I chose C++ because from what I've heard it is pretty versatile and lets you have a lot of control over your computer. Making this program run on windows would make it more useful for people. I'm taking baby steps and my next baby step is to move on to Windows programming after I learn object oriented programming. I've heard about python before but I don't know anything about it. What are it's major advantages over other programming languages? My reference to video games is to where I want to be in the next 5 years. I want to know enough to program a video game. I know its hard but I've learned that if I can get a hold on all the information I need I can learn it. Really what I'm looking for is a book that is written for someone who just learned C++ to move into windows programming.
