Paul,

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?


#3

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.
