Question Composition For Movement

I have move component script but i dont know how to move entities differently. I mean should i create new sub classes of move component? For example I have player and zombie. Their movements are different so i dont know how to do it.

 

I personally favor composition since the whole GameObject/Component structure is a composition design pattern in and of itself.

If you need to be able to relate certain aspects of the various movement scripts you make, you can create an interface for it.

Like so:

Code (csharp):

1. public interface IMovementScript
2. {
3.     GameObject gameObject { get; } //will be implicitly implemented since our scripts are MonoBehaviour
4.     Transform transform { get; } //also implicitly implemented
5.     float Speed { get; set; } //say all movement scripts have speed and you want to be able to modify them polymorphically
6. }
7.  
8. public class PlayerMovement : MonoBehaviour, IMovementScript
9. {
10.     public float speed;
11.     float IMovementScript.Speed { get { return speed; } set { speed = value; } }
12.  
13.     void Update()
14.     {
15.         //update via player inputs
16.     }
17. }
18.  
19. public class ZombieMovement : MonoBehaviour, IMovementScript
20. {
21.     public float speed;
22.     float IMovementScript.Speed { get { return speed; } set { speed = value; } }
23.  
24.     void Update()
25.     {
26.         //update via some other means
27.     }
28. }

 

Oh thank u, should i create new file for each class should i write like u did in same file?

 

They'll have to be in their own file since in Unity any component/MonoBehaviour you want to be able to attach to a GameObject via the editor needs to be in its own file.

The way unity serializes/associates scripts to be attached in the editor is by the guid stored in the meta file associated with the script file. Go into your folder and you should see (it may be hidden) something like:
YourScript.cs
YourScript.cs.meta
