Ok, well... let's say the initial situation is that the circle (carousel) of items is snapped correctly, i.e. The item the camera looks at is at the closest distance to the camera. So if we rotate the carousel left or right the item will start to move away further from the camera. Let's also have a variable that is the current carouselRotation, initialized to carouselRotation = 0. Now as we move the carousel we keep track of how much we rotate, if we rotate right we add the degrees to carouselRotation, if we rotate left we subtract from carouselRotation and wrap around when below 0: if (carouselRotation < 0) carouselRotation += 360 so it's always a positive value (it's perhaps also wise to subtract 360 when it's larger than 360) Assuming the items in the carousel are evenly spread the rotation between each is 360/10 = 36 degrees (as seen from the center of the carousel) Now when we wish to snap we look at the current carouselRotation. We perform a modulo operation on the carouselRotation as follows: tSnapRot = carouselRotation % 36 tSnapRotation is always between 0 and 36 (excluding 36) and indicates how much we have to turn back to get to a snap position. But remember that we don't always want to rotate back, we may have to rotate forward if the next item is closer to us. We can check for this by checking if tSnapRotation > 18, if so then we should rotate forward by (36-tSnapRotation), if not then we should rotate backward by tSnapRotation. Hope this helps you. Let me know.
