Resolved Override OnTriggerEnter2D Method in Subclass

I want override OnTriggerEnter2D method within subclass or derived class I created.

I have tried as per my knowledge but its not working, I can't able to call super class and sub class method within single collision detection.

When the object collide, I want callback for super class and derived class OnTriggerEnter2D methods.

Block Super Class:

Code (CSharp):

1. public class Block : MonoBehaviour
2. {
3.     [HideInInspector] public int xPosition;
4.     [HideInInspector] public int yPosition;
5.     public int health = 5;
6.     //
7.     [SerializeField] Color normalColor;
8.     [SerializeField] Color hitColor;
9.     //
10.     Animation blockAnimation;
11.  
12.     private void Awake()
13.     {
14.         blockAnimation = GetComponent<Animation>();
15.     }
16.  
17.     protected void OnTriggerEnter2D(Collider2D other)
18.     {
19.         if (other.CompareTag(GameConstants.TAG_BULLET))
20.         {
21.             health--;
22.             if (health <= 0)
23.             {
24.                 // destroy block
25.                 Destroy(gameObject);
26.                 //blockSpriterRenderer.DOColor(hitColor, 0.2f).SetLoops(1, LoopType.Incremental).OnComplete(
27.                 //    () => { Destroy(gameObject); } );
28.             }
29.             else
30.             {
31.                 // reduce health
32.                 blockAnimation.Play();
33.                 //blockSpriterRenderer.DOColor(hitColor, 0.2f).SetLoops(1, LoopType.Incremental).OnComplete(
34.                 //    () => { health--; });
35.             }
36.         }
37.     }  
38.  
39. }

GoldBlock Sub Class:

Code (CSharp):

1. public class GoldBlock : Block
2. {
3.  
4.     [SerializeField] GameObject miningItemPref;
5.  
6.     protected void OnTriggerEnter2D(Collider2D other)
7.     {
8.        
9.         if (other.CompareTag(GameConstants.TAG_BULLET))
10.         {
11.             Debug.Log("Bullet Hit: " + health);
12.             GenerateMiningItem();
13.         }
14.     }
15.  
16.     private void GenerateMiningItem()
17.     {
18.  
19.     }
20. }

At present, Sub class's OnTriggerEnter2D() method is getting called.
Please share your suggestion regarding this.

 

You have to mark the method as virtual in the base class and override in the sub class and then call base.OnTriggerEnter2D(other) in the sub class method

@flashframe Thank you for your reply, It helped me a lot
Here is my updated code:
Super Class:

Code (CSharp):

1.  
2. public class Block : MonoBehaviour
3. {
4.    
5.     [HideInInspector] public int xPosition;
6.     [HideInInspector] public int yPosition;
7.     public int health = 5;
8.     //
9.     //[SerializeField] Color normalColor;
10.     //[SerializeField] Color hitColor;
11.     //
12.     protected Animation blockAnimation;
13.  
14.     private void Awake()
15.     {
16.         blockAnimation = GetComponent<Animation>();
17.     }
18.  
19.     protected virtual void OnTriggerEnter2D(Collider2D other)
20.     {
21.         if (other.CompareTag(GameConstants.TAG_BULLET))
22.         {
23.             health--;
24.             if (health <= 0)
25.             {
26.                 // destroy block
27.                 Destroy(gameObject);
28.                 //blockSpriterRenderer.DOColor(hitColor, 0.2f).SetLoops(1, LoopType.Incremental).OnComplete(
29.                 //    () => { Destroy(gameObject); } );
30.             }
31.             else
32.             {
33.                 // reduce health
34.                 blockAnimation.Play();
35.                 //blockSpriterRenderer.DOColor(hitColor, 0.2f).SetLoops(1, LoopType.Incremental).OnComplete(
36.                 //    () => { health--; });
37.             }
38.         }
39.     }  
40. }
41.  

Sub Class:

Code (CSharp):

1.  
2. public class OilBlock : Block
3. {
4.     [SerializeField] GameObject miningItemPref;
5.  
6.  
7.     protected override void OnTriggerEnter2D(Collider2D other)
8.     {
9.         base.OnTriggerEnter2D(other);
10.         if (other.CompareTag(GameConstants.TAG_BULLET))
11.         {
12.             if (health <= 0)
13.             {
14.                 // generate mining object
15.                 GenerateMiningItem();
16.             }
17.         }
18.     }
19.  
20.     private void GenerateMiningItem()
21.     {
22.         Instantiate(miningItemPref, transform.position, Quaternion.identity, transform.parent);
23.     }
24.  
25. }
26.  

I hope this will become useful to other members as well.
