C / Create a double array of sfSprite

« on: February 26, 2018, 09:51:15 pm »

Hello, Im wondering if we could create a double array of sprite.

I tried something like this:
sfSprite *sprite[3];
sprite = malloc(sizeof (sfSprite *) * 3);
sprite[0] = my_sprite create("Document/image/image.png");
sprite[1] = my_sprite create("Document/image/image.png");
sprite[2] = my_sprite create("Document/image/image.png");
sfRenderWindow_drawSprite(window, sprite[0], NULL);

I tried a lot of otherways but it don't work. I would like to know if it's possible.

C / Texture how to load area image

« on: August 20, 2017, 02:57:02 pm »

Hello the community, I have a little problem. I don't know the structure to load a specific area in a texture.

Look at my code:

#include <SFML/Audio.h>
#include <SFML/Graphics.h>
#include <SFML/Config.h>
#include <stdlib.h>
#include "my.h"

int     map_creation(sfRenderWindow* window)
{
  sfTexture* mtexture;
  sfTexture* ptexture;
  sfSprite* map;
  sfSprite* player;
  sfEvent event;

  mtexture = sfTexture_createFromFile("map1.png", NULL);
  if(!mtexture)
    return EXIT_FAILURE;
  map = sfSprite_create();
  sfSprite_setTexture(map, mtexture, sfTrue);

//In here im not sure about the stIntRect(10, 10, 32, 32)
  ptexture = sfTexture_createFromFile("sprite.png", sfIntRect(10, 10, 32, 32));
  if (!ptexture)
    return EXIT_FAILURE;
  player = sfSprite_create();
  sfSprite_setTexture(player, ptexture, sfTrue);

  while (sfRenderWindow_isOpen(window))
    {
      sfRenderWindow_clear(window, sfBlack);
      sfRenderWindow_drawSprite(window, map, NULL);
      sfRenderWindow_display(window);
     
      while (sfRenderWindow_pollEvent(window, &event))
        {
          if (event.type == sfEvtClosed)
            sfRenderWindow_close(window);
        }
    }
 
  return (0);
}
 

The console says :
gcc -o tekadventure main.c tekadventure.c -W -Wall -Werror -lcsfml-graphics -lcsfml-audio -lm libmy.a
tekadventure.c: In function ‘map_creation’:
tekadventure.c:30:53: error: expected expression before ‘sfIntRect’
   ptexture = sfTexture_createFromFile("sprite.png", sfIntRect(10, 10, 32, 32));
                                                     ^
Makefile:26: recipe for target 'tekadventure' failed
make: *** [tekadventure] Error 1


I know I did not write it the right way, I tried to look at SFML c++ and adapt it to the CSFML API but is not working.

Thank you in advance.
