Window / Console Window display option not working SFML,Cmake,Mingw,Codeblocks

« on: February 02, 2013, 06:00:33 pm »

Hello all,

I am trying to make a gui application with code blocks, SFML, and Cmake but on windows I have a problem of the console window being displayed. I do not want it to be displayed.

I am using cmake to generate my project. I am generating Codeblocks Mingw32 makefiles. Once I generate those makefiles I open up the generated codeblocks project and try to change the setting from console to GUI in properties but it doesn't work.

I believe the problem is that I am setting a variable in codeblocks even though codeblocks is using Mingw32 as a tool to compile so the setting has no effect. Is there any way to set my program to be a GUI in the Cmake file?

Right now I have a workaround of using windows.h to find the console windows and hide it with this command function in my console class:
void ConsoleWindow::HideConsoleWindow (void){
//----------------------------------------------------------------------------------------------------
   ShowWindow(this->CONSOLE, SW_HIDE);
}

I like how this works, but I don't like how the console pops up on the start of the program then disappears. Is there anyway I can fix this via Cmake or codeblocks?

Thanks,
Brent

Graphics / GetEvent() Deprecated? - SFML 2

« on: April 18, 2011, 10:01:54 pm »

Well after I updated my repo and re-built SFML I noticed that there was no GetEvent() function because when I tried to build my project I got this:

class sf::RenderWindow’ has no member named ‘GetEvent’

Could someone please help me out here?

Update: I got the makefile thing fixed but now I am having trouble with compiling.
Here are some of my errors.

Previous stuff to help others that i figured out down here...

UPDATE:
Tried using vc++ libs but only got errors like this.
undefined reference to `sf::RenderWindow::~RenderWindow()'
So how do I use a makefile?


Update:
I made makefiles but I can't figure out how to compile them..
I tried a codeblocks makefile and when opened in CB nothing happened either. It said
 'make.exe -s -f Makefile all' in 'C:\SFML\Build\CodeBlocks' failed.

Update:
I installed mingw.
I went into cmd and typed this: set PATH=%PATH%;C:\MinGW\bin cmake
Then I went back to cmake and it said. Missing libgmp-10.dll.




Original Post:

Ok well I have the latest source from the svn and I tried opening it up in cmake and setting the files the mingw make files. And then it gave me this:






Here are my errors:

General / How do I create my own GetPosition() Function?

« on: December 28, 2010, 05:07:32 am »

Well I am working with OpenGL now and I want to return the position of the 3DRect like this. GetPosition().x or GetPosition.y or GetPosition().z. So how would I do this?

Also on a side note. How do I rotate around a local origin and not a world origin. Like rotate in place?

Graphics / GluPerspective vs. GlOrtho

« on: December 23, 2010, 12:39:31 am »

Well I am having some trouble. I am trying to be able to draw anywhere in the world but be able to move the camera. Like any 3D game. But IDK which one to use, glOrtho or gluperspective. Whenever i try gluperspective and try to draw at 0,0 it is at the center of my screen. I want it to be in the bottom corner... But with glOrtho it makes everything in teh world really small but draws them in the corner.. So could some point me in the right direction.. And also how I would move the camera..

I know there is glulookat but I will use that after I make my player...

Graphics / Creating an OpenGL Cube Class

« on: December 19, 2010, 08:30:07 pm »

Ok Well I am trying to create an OpenGL cube class but if I try and translate the cube and then have a gl shape folowing it, it affects that shape. Is there anyway that I can have a matrix or something for each cube shape and have every tranlation or rotation done no matter where it's done only effects my shape. So it kinda like each shape has it's own little space in memory and when I call a function it affects that variable or matrix which is in each class.

So pretty much how would I make a function only affect a shape of my choice. would I have to put the shape in a seperate matrix and then translate that martix which is a variable for the cube class?

If so how would I do this?

I call it like this in main..

Grass.SetPosition(x,y,z); //Cube doesnt display inless this is in while..
Grass.Draw();

General / Quick Question about OpenGL

« on: December 15, 2010, 03:19:42 am »

Well I am trying to create a class called Block. The blocks are all the same but with different textures. With the texture is there anyway I can use just sfml to put an image on the block and have it pretty much glued on. Also here is my real question, how do i manipulate one shape? The constructor of this class will call all of the verts but if I want to call glrotate3f or gltranslate3f. How would I go about manipulating just that shape? Would I need my own matrix? Or would I just call glMatrixMode(MODEL_VIEW) or whatever it is and then translate. And it would know what shape I am talking about or not?

Ok well Here is the example code from the repository and I have some questions about it after the code.

        text.SetColor(sf::Color(255, 255, 255, 170));
        window.Draw(text);
        window.RestoreGLStates();

        // Finally, display the rendered frame on screen
        window.Display();
    }

    // Don't forget to destroy our texture
    glDeleteTextures(1, &texture);

    return EXIT_SUCCESS;
}

So right off the bat you set up a texture with gl called texture right?
Then the Opengl initiative stuff and then you bind the texture corrrect?
After that you start the main loop and get the events and then You save the gl states? what does that do? But after that you restore it? Does it do Opengl stuff like popping and pushing matixes?
What does set active do?

Also when you call all of the tranformations how do you make it only apply to one shape? Like make it more object oriented?

SOrry I have more questions but I gtg..

Graphics / Input Is not being handled well

« on: December 10, 2010, 04:11:55 am »

Well I have built my program fine but when I try and use it and I use my mouse on the window it stops working. I am pretty sure it is not handling input correctly... Also one of my images is just showing up white. It is just an inherited sprite class...

Window / OpenGL not Working

glEnd();

glFlush();
}

void Initialize() {
glClearColor(0.0, 0.0, 0.0, 0.0);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(0.0, 1.0, 0.0, 1.0, -1.0, 1.0);
}

int main(int iArgc, char** cppArgv) {
sf::Window App(sf::VideoMode(800,800,8), "OpengGL Test");
Initialize();
while(App.IsOpened())
{
glClear(GL_COLOR_BUFFER_BIT);
Draw();
App.Display();
}
return 0;
}


Ok Well I have gotten rid of those errors by creating a new project and trying to do all of this again but now window doesnt display. It doesnt pop up at all...
