Game screen

[Begginer]

i have a question, i want to make a small game, but i dont want to write the whole screen more then once, i know it is possible because my friend made it and he didnt even use matricates, thanks :D

By this do you mean a menu? or maybe the map?

Have you considered the use of functions: (?) http://www.cplusplus.com/doc/tutorial/functions/

I think he means moving the cursor position.

Did you read it? =P

Dude, your friend is either lying or he doesn't know what he's talking about. If you want to make a C++ computer game and you're a begginer (sic) you need to start simple and learn a graphics package. C++ itself has NO CONCEPT of a computer screen or a keyboard. It only knows what streams in and out of its I/O. It can't possibly remember what is on the display YOU are looking at (that info is in graphics card RAM) so it MUST refresh the entire screen to reflect changes in its game memory. If you're friend is using some libraries under the hood to fool himself then good for him but you should be smarter and use one of the powerful graphics and sound libraries available for C++.

You will go nowhere until you understand these concepts. Posting the same question again will not get you the magical piece of code you're looking for: http://cplusplus.com/forum/beginner/51426/

lol u spelled beginner wrong, i spelled it wrong on purpose...
anyway, that doesnt help me one bit i already said i dont want to use that, i only want a small normal 2d game in console... without sprites...

this was a small console game i worked on in uni, no graphics just ascii

the only way ur gonna get proper 2D or 3D graphics in a game would be to use a graphics API such as DirectX or OpenGL

Agree. The closest to console GUI you can get is from someone told me in this forum to use ncurses library. It is still console but provide some resemblance of a GUI.

Or since Web is so prevalent nowadays, build your game running in the browser! Adobe Flash is often used to create interactive game effect with relative ease.
