Do any variables declared within methods generate memory allocation?
Let's say there is a method that takes a parameter, like int MyMethod(int value) and it then does some math to return a variable like if(value - someValue < someOtherValue) { return int someNewValue; } would it allocate memory each time someNewValue is returned?
I'm wondering if you have created a private int at the top of the class it only allocates memory once, while this does every time it's called, which is what I thought made sense... Can anyone confirm or deny that? Perhaps unity knows to just keep ahold of someNewValue and edit it, rather than create a new variable each time something is returned by this method.

Don't do that; it's bad programming. Only declare variables inside functions, unless they specifically need to be shared with other functions. Anyway, it depends, but primitive types such as int are (generally) declared on the stack, not the heap, so there's no GC. Local variables typically perform slightly better, and as I mentioned global variables are not good programming practice unless you actually need them, so avoid that; you won't be optimizing anything (but rather the opposite).
