SDL + Classes Question

darkzerox · #1 23-May-2004, 15:05

CPP / C++ / C Code:

class cSprite
{
      SDL_Surface *sprite;

    public:
      // initialize
      cSprite()
      {
         sprite = SDL_LoadBMP(img);
         SDL_SetColorKey(sprite, SDL_SRCCOLORKEY, SDL_MapRGB(sprite->format, 255, 255, 255));
      }

      // general
      char name[100];

      int hp[2];
      int mp[2];

      // graphics
      char img[100];

      int x;
      int y;
      int w;
      int h;

      void draw()
      {
         DrawIMG(sprite, x, y);
      }
};

I'm going to read in sprite.img from a file...

The problem is that I will have to construct cSprite sprite before I can read in sprite.img which means that it will try to load a non-existant image...

Would there by any easy way to read in sprite.img before having it try to load sprite.img? Or should I just change my constructor to something like init() then read in all my information, and then call that?

...great.. I just lost everything I just typed. I hate browsers!

So yah.. no edit button huh? Or am I blind?

I've come up with somewhat of a solution. I'm going to read the file in the constructor itself.

But I'm having a dumb moment and I can't seem to figure out how to get it to read properly.

Here's the contents of my file

Code:

$NAME		Angela;
$IMG		img/char/temp.bmp;

$NAME		Carlie;
$IMG		img/char/carlie.bmp;

Basically I want it to search for the '$' character, then once it finds that, it reads in a string, ie, 'NAME'

Once it finds 'NAME' it calls this function

CPP / C++ / C Code:

void getl(char *tmp)
{  while (isspace(fin.peek())) fin.get();
   fin.getline(tmp,255,';');
}

to read in 'Angela' (the function just removes all the white spaces before it.. it works)

And then it stops reading as soon as it gets to the next '$NAME'. I need it to leave the cursor just before '$NAME' so that when I call this function again, it continues where it left off.. reading in the next character. I assume I'll need to use something like fin.unget().

I've done stuff like this before, but I can't seem to get it to read properly at all this time.

Any help would be appreciated..

CPP / C++ / C Code:

char ch, str[32];

CPP / C++ / C Code:

         char ch, str[32];

         while(strcmpi(str,"name")!=0 && !fin.eof())
         {  fin >> ch;
            while(ch != '$' && !fin.eof())
               fin >> ch;
            fin >> str;
         }
         if(!fin.eof())
         {
            getl(name);
            strcpy(str,"");
            while(strcmpi(str,"name")!=0 && !fin.eof())
            {  strcpy(str,"");
               fin >> ch;
               while(ch != '$' && !fin.eof())
                  fin >> ch;
               fin >> str;
               if(strcmpi(str,"img")==0)
                  getl(img);
               else if(strcmpi(str,"trans")==0)
               {  fin >> trans[0];
                  fin >> trans[1];
                  fin >> trans[2];
               }
               else if(strcmpi(str,"hp")==0)
               {  fin >> hp[1];
                  hp[0] = hp[1];
               }
               else if(strcmpi(str,"mp")==0)
               {  fin >> mp[1];
                  mp[0] = mp[1];
               }
            }
         }

this will read name and image... but nothing else
