Graphics / Change size of texture, sprite without scale [SOLUCIONADO]

« on: August 29, 2016, 12:26:30 pm »

Hello,
I am doing an animation which is changing the size and the color of a sprite with texture created by:

struct rect_s{
        int width;
        int height;
        sf::Color color;
        sf::Texture texture;
        sf::Sprite sprite;
} object;

sf::Uint8* updateMatrix(sf::Uint8 * matrix, sf::Color color, int size){
        if (matrix != 0)delete[]matrix;
        matrix = new sf::Uint8[size];
        for (int i = 0; i < size; i++){
                matrix[i++] = color.r;
                matrix[i++] = color.g;
                matrix[i++] = color.b;
                matrix[i] = color.a;
        }
        return matrix;
}
        object.width = 50;
        object.height = 50;
        object.color = sf::Color::Red;

        sf::Uint8 * matrix = 0;
        matrix = updateMatrix(matrix, object.color, object.width * object.height * 4);

       
        object.texture.create(object.width, object.height);
        object.texture.update(matrix);
        object.sprite.setTexture(object.texture);
 

Later i am doing that:

                if (((float)(clock() - last_t)/CLOCKS_PER_SEC) * 1000 > 30){

                        switch (control.cycle)
                        {
                        case 0:
                                object.color.g++;
                                object.color.r--;
                                object.width++;
                                if (object.color.g > 240)control.cycle = 1;
                                break;
......
//I update the texture size with calling create again but is not working
                        object.texture.create(object.width, object.height);
                        matrix = updateMatrix(matrix, object.color, object.width * object.height * 4);
                        object.texture.update(matrix);
 

How can i do that?
