I'm certain this has been asked before, but I do not want to use sks files. I have some very old Cocos2d code that I'm trying to port without a complete rewrite. I would rather programatically move my scene sprites around based on the screensize and do it in Obj-C. It is unclear to me how to do this. I sort of found an answer here: https://stackoverflow.com/questions/43927323/are-spritekit-scene-sks-files-necessary-in-my-project Tried to do something equivalent in Obj-C, but got no where.
