Why use Serializefield over just making public var

Code (CSharp):

1.  
2.  
3. [Serializefiled] int moveSpeed;
4.  
5. vs
6.  
7. public int moveSpeed;
8.  
9.  

 

Hi so im just curious if this is a preference thing or is there a difference between the two from my limited exp and knowledge it does the same thing?

 

private allows you to control access to the variable so it cannot be modified by other scripts. This is an important aspect of Object Oriented Programming called Encapsulation.

Awesome thank you.
This makes allot more sense now.

 

It took me a while to come to understand the importance of enforcing access control on scripts. Out of the gate, I liked how easy it was to change values directly by making them public. I could work faster and write less code.

One of the problems this creates is allowing you to make code that is tightly coupled. Meaning all my scripts would tend to be interconnected in a way that wasn't easy to maintain or update. Setting proper access control forces you to think of things as separate systems and will save you a lot of trouble in the long run.
