I am working on puzzle app in which i need to snap irregular shapes as they come in contact of one another as i am new to game development so i dont have any idea how to achieve this functionality in my app.Any suggestion would be highly appreciated.
It's true that each image has an irregular shape, but you don't need to snap that shape. It also does have a bounding box, and you know where that bounding box should be in the solved puzzle. Note that those bounding boxes can collide but it doesn't matter at all! so you just need to check if the bounding box almost as it's rightful position, and if it is, you just need to move it to it's exact position and lock it.
