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?
