Hello, I made a function which take Sprite and fill dynamic allocated 2D bool array with 1 or 0 depends on if Alpha channel is bigger than 0.f or equals 0.f.
1 = bigger than 0.f, 0 = equals 0.f. It works great.
Now I still trying to figure way to check collision depend between two rectangles two sprites. First I need to change two sprites into rectangles and check for intersects, if intersects exist then I fill overlaping rectangle with new sfIntRect and check there for pixel collision? But how do I check it? I change it's global coordinates into local and run throught 2D array and if it gets to 1*1 then return collision happend?
Plus I got problem with views:
When I don't use view sfIntRect_Intersects checks collision perfectly but if I use view then it's showing that two rectangles collide no metter where I am except being before the rectangle, minimal code:

Function to change sprite to rectangle:
sfIntRect SpriteNaRect(sfSprite* &duch)
{
sfIntRect Prostokat;
float x,y;
sfSprite_TransformToGlobal(duch, 0,0,&x, &y);
Prostokat.Top = (int) y;
Prostokat.Left = (int) x;
Prostokat.Bottom = (int)(y + sfSprite_GetHeight(duch));
Prostokat.Right = (int)(x + sfSprite_GetWidth(duch));
return Prostokat;
}
So far I know that doesn't work because when I use view there is like another ratio fo pixel because sKamien instead of 305 widht it has like 50 when I move my view and when I finally reach 405 pixel by moving my character then it says that rectangles doesn't collide.
