VS 2012 + SDL issue
« on: February 01, 2013, 11:01:26 pm »
I got all of the libs/includes/dll's set up correctly and the program compiles just fine, and runs, but the window that pops up doesn't display anything. What its supposed to do is display an image, after some debugging, I think it SDL_LoadBMP cant seem to find the image. The same code worked just fine on Ubuntu at school. I have the image in the same directory as the program and the project, and I have tried just placing the image in C:\, but it still dosen't work. Has anyone else had this problem?

I can upload the code if you really need it.

The code might be important. Try with an absolute path to see if maybe its a problem with relative paths?

FIXED: I loaded the image before setting the video mode, although I don't know if it dose have anything to do with it
Was:
Code: [Select]
image = LoadImage("image.bmp");
screen = SDL_SetVideoMode( SCREEN_WIDTH, SCREEN_HEIGHT, SCREEN_BPP, SDL_SWSURFACE );

Now:
Code: [Select]
           screen = SDL_SetVideoMode( SCREEN_WIDTH, SCREEN_HEIGHT, SCREEN_BPP, SDL_SWSURFACE );
image = LoadImage("image.bmp");

Do you use SDL_DisplayFormat for helping loading the image to format well? That could cause the problem with the image.

Yes, I had that implemented right away, I based this off of a tutorial I have been using, the source is below if anyone wants it.

New question, when using a list, why does the destructor for the object that you are placing in the list get called?

I was tracing the code with the debugger and it seemed to do that, maybe I messed up somewhere, but it still doesn't make a lot of sense to me that it would call the destructor, when creating an object.

If you are placing an object in one of the SDL containers and goes beyond allocated memory, then the container will move itself to another location in memory. I don't know if it calls the destructor on objects inside itself though.

Not much is known about these mysterious people except that they all carried calculators of some kind and they all seemed to converge on one house in particular. Experts estimate that the combined power of their fabled calculators is greater than all the worlds super computers put together. The group seems to be holding out in the home of a certain DJ_O, who the Omnimagians claim to be their founder. Such power has put the world at a standstill with everyone waiting to see what the Omnimagians will do...

Wait... This just in, the Omnimagians have sent the UN a list of demands that must be met or else the world will be "submitted to the wrath of Netham45's Lobster Army". Such demands include >9001 crates of peanuts, sacrificial blue lobsters, and a wide assortment of cherry flavored items. With such computing power stored in the hands of such people, we can only hope these demands are met.

In the wake of these events, we can only ask, Why? Why do these people make these demands, what caused them to gather, and what are their future plans...

I'm using an STL list as the container, maybe I should look into an SDL one though

Oops, that was a typo, I meant to say STL, as in the Standard Library. :P

Is the image thing fixed yet? It could be a path issue. The path relativity is from where you run the program, so maybe you're running the program in a different folder than your image?

Some people need a high five in the face... with a chair.
