Polymorphism - Organize my scripts
I have an gameObject, let's call it: "Brick". A brick can be "draggable" and / or "breakable" (meaning, some bricks are only draggable, some only breakable, some both breakable and draggable.
In order to organize my C# code, I thought about creating two classes: "BrickDraggable" and "BrickBreakable". But BrickBreakable cannot logically inherit from BrickDraggable, and vice versa.
This issue vaguely reminds me some university courses where a old eccentric teacher talked about polymorphism, but it was a long time ago...
Therefore, my question is: how can I organize my classes in unity? Should I add two different C# scripts (component) to the breakable and draggable bricks?
Thanks in advance :)
Yes you can't inherit from more than 1 class. So I can't really recommend any solution without knowing interoperations between both Draggable and Breakable. The most obvious ones would be:
1) As you said add 2 different scripts if they have nothing in common and you won't really interoperate between both of them and they are all the same.
2) Create interfaces of Draggable and Breakable (check my answer THERE for code example) and you can have as many interfaces as you like.
3) Add enum flag that has Draggable and Breakable, then depending on that enum which will be common to all bricks do your actions.
4) Just instantiate classes in your brick class, like so:
Draggable drag = new Draggable();
Breakable break = new Breakable();
...well that's enough I guess, the most obvious already provided, hard to tell which one should you choose depending on info you've provided.
Hi! Thanks for your feedback, it really helps! For information, I was not sure how to deal with Interfaces, so I did something between your 3) and 4).
I created three classes: - "BrickBreakable" - "BrickDraggable" - "Brick"
In the class Brick ($$anonymous$$onobehaviour), for example, my Start() function looks like:
public bool draggable;
public bool breakable;
private BrickDraggable brickDraggable;
private BrickBreakable brickBreakable;
public void Start(){
if (draggable) {
brickDraggable = new BrickDraggable();
brickDraggable.Start ();
}
if(breakable) {
brickBreakable = new BrickBreakable();
brickBreakable.Start ();
}
}
Thanks again, Bliss
