Question How to I access (or read) another game object's enums through OnTrigger collisions?

Hi, I just have a quick question.

So I'm making a 2D game and to make it easier on myself in the long-run I wanted to create a system where I input the various properties of an attack and when my player character is hit it will react according to what I've put as it's responses.

My problem is that I don't exactly know how to access the properties of an object while it is colliding in the code. Nor do I know if that it is actually the best way to go about it.

Firstly, I want to be able to differentiate between a light and a heavy attack so that a different amount of health can be taken from the player character, and if it was just two different attack types I would used scripts but I want there to be several different parameters that the player can react to.

Here is what my Enemy Attack Parameter Script looks like:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public enum EnemyAttackStrength
6. {
7.     light,
8.     heavy,
9. }
10.  
11.  
12. public enum EnemyAttackType
13. {
14.     melee,
15.     ranged,
16.     special,
17. }
18.  
19. public enum EnemyAttackElement
20. {
21.     none,
22.     fire,
23.     ice,
24.     electric,
25.     crystal,
26.     poision,
27. }
28.  
29. public class EnemyAttack: MonoBehaviour
30. {
31.     public EnemyAttackStrength thisAttackStrength;
32.     public EnemyAttackType thisAttackType;
33.     public EnemyAttackElement thisAttackElement;
34. }

And here is the excerpt where I'm trying to have the player detect what enum the enemy attack is:

Code (CSharp):

1.  private void OnTriggerEnter2D(Collider2D collision)
2.     {
3.         if (collision.gameObject.tag == ("Enemy"))
4.         {
5.             if (collision.gameObject.GetComponent<EnemyAttack>()) //obviously a mockup
6.             {
7.                 if (thisPlayerInvulnerability == playerInvulnerability.vulnerable)
8.                 {
9.                     health = health - 5;
10.                     player.tookDamage = true;
11.                     ChangeVulnerability(playerInvulnerability.invulerable);
12.                     StartCoroutine(InvincibilityTimer());
13.                 }
14.                 else if (thisPlayerInvulnerability == playerInvulnerability.invulerable)
15.                 {
16.                     health = health - 0;
17.                     player.tookDamage = false;
18.                 }
19.             }
20.         }

Thank you for anyone willing to help, I really appreciate it!

 

Just assign the collision.gameObject.GetComponent<EnemyAttack>() to an EnemyAttack local variable. Then you access it via that variable.

Just for example, here is my code in my game for a playercontroller when the player activates a grab:

Code (CSharp):

1. public void Grab(bool grabAll = false)
2.     {
3.         Collider2D[] potentialPickups = Physics2D.OverlapCircleAll(GrabPosition.position, GrabRadius, GrabLayers);
4.         if (potentialPickups != null && potentialPickups.Length > 0)
5.         {
6.             Collider2D firstPotentialPickup = potentialPickups[0];
7.             ResourceNodeController rnc = firstPotentialPickup.GetComponent<ResourceNodeController>();
8.             if (rnc != null)
9.             {
10.                 ResourceNode rn = GameCore.Current.Resources[rnc.ResourceNodeID];
11.                 if (rn.HarvestHealth == 0)
12.                 {
13.                     InventoryContainer results = rnc.GrabResource();
14.                     if (results != null)
15.                     {
16.                         PlayerData.Current.Inventory.MergeContainers(results);
17.                         if (!results.IsEmpty())
18.                             PlayerData.Current.ToolBar.MergeContainers(results);
19.                         if (!results.IsEmpty())
20.                         {
21.                             GameObject go = Instantiate(GameResources.Current.LootBagPrefab, transform.position, Quaternion.identity);
22.                             InventoryContainerController lc = go.GetComponent<InventoryContainerController>();
23.                             lc.InventoryContainer_var = results;
24.                             lc.Initialize();
25.                         }
26.                     }
27.                 }
28.             }
29.             else
30.             {
31.                 IInteractableElement iie = firstPotentialPickup.GetComponent<IInteractableElement>();
32.                 //InventoryContainerController lc = firstPotentialPickup.GetComponent<InventoryContainerController>();
33.                 if (iie != null)
34.                 {
35.                     if (grabAll && iie is InventoryContainerController icc)
36.                     {
37.                         PlayerData.Current.Inventory.MergeContainers(icc.InventoryContainer_var);
38.                         if (!icc.InventoryContainer_var.IsEmpty())
39.                             PlayerData.Current.ToolBar.MergeContainers(icc.InventoryContainer_var);
40.                     }
41.                     iie.DisplayUI();
42.                 }
43.             }
44.         }
45.     }

 

My god you did it... Thank you so much
