Can anyone tell me how to make an update patch for my iphone game?
Do I need to build the whole game out again?
After I put the whole updated game on app store, do people have to pay for it again?
Also, is the previous save in the game reserved?
Correct you have to rebuild the whole game and upload a new version to iTunes connect
No users won’t have to pay for it again (thats not possible at all)
And yes the previous save unless explicitely deleted, will remain present
thank you very much for your answer! =]
I also found this answer very useful as it is something I have been wondering about for a long time. Just to clarify variables in ‘playerprefs’ will remain after the older version has been overwritten with the new ?
PlayerPrefs on iOS means NSUserDefaults so anything that holds for the user defaults on application updates holds for your Unity Project as well. (this information should allow you to find out quite a lot more about what where and how)
