I'm just wondering about the implementing of the collision response of bullets and the fours obstacles. https://www.youtube.com/watch?v=LCNTwG3MGEg
When a bullet hit, a one black pixel is overwritten. How would one implement it in modern games, because what I feel that they overwrite the framebuffer, but right now I will only swap the sprites or images of different hit-obstacles.
If we say we will draw it as a pixels of bitmap, should then I make then a pixel to pixel collision detection If I want to clone the same behavior?
