Without that step, you could be running yourself in circles for a while. When you design/develop to interfaces, what you are doing is confirming that you really know what your class is about before you get started.

first we ask, 'How do client classes want to access this new class what service(s) does it need to provide them?', and after defining that service interface, we decide how to build the internal functionality of that class to serve that interface and thus satisfy client classes' requirements.

The core concept is this: Whether it's for a banking system or a video game, classes are best designed from the outside in, i.e. The reason for this approach is that programming to an interface can improve development times, if the concepts behind it are clear. I think you'll find the reason that getters and setters are such a popular way to do things, is due to the Gang of Four's well-known suggestion to 'Program to an interface, not an implementation.' Unfortunately novices frequently know about the practice of making redundant getters and setters, but not the reason behind it, thus making it a little pointless. But I personally have no interest in that. Of course, if you're aiming to work at Epic or Microsoft one day, you damn well better learn what they consider 'good form' and start practicing it now.

because once your code is compiled, no one else is going to see it! In the end, write code that makes sense to you, that you can maintain. In fact, Python doesn't have TRULY private variables, as they can still be accessed directly, it simply becomes a little more difficult to do so. Variables should be public unless you REALLY need them to be private. In python, code readability and brevity is good form, and using getters/setters when not needed is frowned upon. What 'good form' is varies widely from one language to another. I'm saying to use them when you need to, when it makes sense to do so.ĭon't simply do it because a teacher or an author (who have likely been programming for less years than many of us here) says it's the 'standard' or 'good form'. I'm not saying not to use setters/getters. Instead in the setter you can make sure it doesn't go below 0.Ĭlick to expand.And that folks, is MY point. It could produce an undesired result if you are never expecting it to go bellow 0. You wouldn't want someone to just accesses 'speed' directly and do something like speed-=50 and then you wind up with -25. It does keep other programmers in line (and yourself). You may want to change how an inheriting class deals with what is being sent to a class member.īut basically, it just good just good for the fact that it leaves you room to add code in the future, since you never know.Īnd yes. The other major benefit is with inheritance. Then if you need to change things around, you'd have to find that code in every spot. If you have various objects that might pass data to name, you wouldn't want to have to repeat that code every instance accessing it. Or when you decide later on, you need to add some sort of validation or some other instruction of the data, it's built right into the class itself. It's a good standard of putting code like this. Unfortunately, Unity teaches bad practices since the editor needs to see public variables (tsk tsk). Allowing direct access to its internals violates this concept. The concept is that you should aks an object to do something or ask it to give you some information without caring *how* it does it. Also, what if you eventually don't even use a variable anymore but store it somewhere else?

It's easier (and better) to just start with setters/getters. What if you started with a public variable 'name' and allowed people to access it directly but later you want to add validation so only names with no numbers can be set? You'd have to go and change all the code from 'myclass.name = xyz' to 'myclass.SetName(xyz) ' or whatever. The answer is that it allows you to make internal changes to the class without disrupting outside access.
