iusinbello	Hum... I need some help about making graphical applications via C/C++... First of all: What I need? My compiler: Dev-C++. -=-=-

blanko1324	You could either: -Learn OpenGL -Learn DirectX Or, start a bit easier with a graphics engine like HGE, which would be my suggestion. It's what I use now. Just go though the first four or five tutorials and you'll be good to go. And careful, your newb is showing. (Just kidding.) -=-=- My Twitter

JL235	If your new to programming I wouldn't bother messing with OpenGL or DirectX. You can of course also use SDL, which is a very popular choice and has it's own drawing functions. It can also be easily used with OpenGL. You could also try getting a book on game programming with C++. There are lots out there and GameDev has a big book review section you could look through for any recommendations.

iusinbello	Hum... HGE... I'll try it. And careful, your newb is showing. (Just kidding.) Lol... for a moment i thought you were referring to https://www.newb.ie/... -=-=-

iusinbello	@Diablos: I dont want to make "games" via C/C++... I will use the graphical interface only for 2D apps... -=-=-

Jayenkai	Wow.. That's such a badly chosen web address! Back on topic, Dev-C++ is a decent choice. IIRC it contains most thing to get you up and running. Look in the directories for the examples, and see if there's an OpenGL one in there. If there is, try copy+pasting the directory, and hack+slashing the code contained within, until you can figure out what the heck it's all doing! Or, try something like HGE. But you'll still have to faff about getting it all installed, and running happily! -=-=- ''Load, Next List!''

JL235	Are you running Windows? If so get Visual Studio. Sorted.

iusinbello	whoa your right Jay! I have found a nice OpenGl example! -=-=-

hyruleknight	if you are a windows user get visual studio from microsoft's website. it is the best C/C++ IDE i have ever used if you are a mac user then try Xcode and if you use linux try KDevelop -=-=- i like green haired girls...

power mousey	umm.....hmmmmm.....perhaps??? well, I have the Dev C++ package as well. I also have and used Allegro game library too. At the time the latest versions of both Allegro and the Dev C++ system were in this book I bought a few years ago. I think the book is in its third edition now. The book is "Game Programming All In One" and by Jonathan S. Harbour cheers power mousey

Phoenix	Visual Studio is a very good IDE (msdn2.microsoft.com/en-us/express/aa975050.aspx), and if you're just starting I recommend SDL.
Sat, 11 Aug 2007, 11:49
JL235	What exactly are you planning to make? That would probably help with suggestions. Cos if your making applications then don't use OpenGL, DirectX or SDL. They are all for graphics not GUI's.

Blitz3Dman	So... if I want to create graphical effects in C++ I have to go download something extra..? I wonder the same thing and all I really want is the C++ equivalent of Write and Read Pixel, although preferably with RGB rater than hex. Is there a command for this or is downloading more stuff the only way to go? -=-=- There are 10 kinds of people in this world - ( Insert 16 remarks about to what extent people know hex here )

JL235	Blitz3DMan I wonder the same thing and all I really want is the C++ equivalent of Write and Read Pixel, although preferably with RGB rater than hex. Is there a command for this or is downloading more stuff the only way to go? No, there is not a command. Languages don't do graphics, libraries do. So you will have to download an extra library and try it out. Although languages are kind of moving away from being just a language. C# (although technically .NET) and Java come with standard GUI and 2D libraries. @iusinbello: Again I recommend using Visual Studio. It's built for making not applications, but Windows applications. You could also try using a higher level language as it will be (on average) easier and less work for making an application. Namely a .NET language (C#, F#, J#, VB) or Java.

mike_g	In C you can perform pixel writing operations much faster, because you can write each one directly to memory, instead of having to pass co-ordinates into a function which has to convert them. If you use decide to use SDL then heres a writepixel function I made: void WritePixel(int x, int y, Uint32 col) { Uint32 pix; x=4; y=4GRAPHICS_WIDTH; pix=screen->pixels+x+y; *pix=col; } --v

Afr0	Just a slight followup to Ingenum's post: To do anything with Win32 these days, you have to download the Windows SDK if you're using Visual Studio, and I think perhaps you even should if you're using DevC++, because it most likely doesn't contain the latest header files etc. Windows SDK for Vista and XP -=-=- Afr0 Games Project Dollhouse on Github - Please fork!

abc	Just a few things: do anyone knwo that iusinbello/ingenium/ingenium1 are the same guy/lamer?
Mon, 13 Aug 2007, 08:57
Jayenkai	/lamer Ingenium left, and wanted his account deleted. Then he made another account. And now he's made a third one... Clogging up my database, and making me rather annoyed. -=-=- ''Load, Next List!''
Mon, 13 Aug 2007, 08:59
abc	..Really? So, why does he continue posting with all his accounts?

shroom_monk	iusinbello = ingenium? Now I'm even more confused, after I noticed this 2 days ago... -=-=- A mushroom a day keeps the doctor away... Keep It Simple, Shroom!

abc	"Now I'm even more confused, after I noticed this 2 days ago..." ? It was just to point out that he auto-replied to himself on the same thread..
Mon, 13 Aug 2007, 10:48
JL235	No he hasn't. I believe two of his accounts are also kinda merged together by Jay. It means he looks like Ingenium1 on the forum but just Ingenium in the MudChat. Besides, has he actually done anything wrong?
