Unity3d PlayerPrefs only allow saving certain types - string, float, and int32. Since int is composed of 32 bits, it should be able to store 32 flags or a bool of length 32.
So far, I've thought about setting the int based on a binary number of 32 digits, where each digit represents a flag. I'm having trouble doing this with consideration of negative numbers.
Is there a way to access each individual bit of the int without recursive math to store and use them as flags?
