hi, i dont understand. Paper Sprite i set to ignore on its collision BUT all those “Upper” is the box collision which i set to “block all” and yet when i play the game, it phase through the floor! But when i set the paper sprite to block all and upper to ignore all on their collision, it landed on the floor, why? is it buggy? im so confused, why the collisions are acting so weird here?
