Game Lessons



In your previous course we learned that (0,0) coordinate is in the top left corner. How come now with spriteKit we got it in bottom left corner?


Every game/UI system has it’s own coordinate system. The (0,0) will be in different locations and you will have to adjust code/logic.

They all vary. Sprite Kit uses the bottom left corner. UIKit uses the top corner.
