Question Tapping button to attack on mobile, problem with range

I'm getting one error which I can't figure out how to fix, I'll include the code below, I'm trying to make it so when I tap on the attack button, it will deal damage to the closest enemy within a certain range, I just can't figure out the range part. Can someone help me with this?

Code (CSharp):

1. using UnityEngine;
2.  
3. namespace Combat {
4. public class PlayerCombat : MonoBehaviour {
5.     public  Animator animator;
6.     [SerializeField] Transform target;
7.     [SerializeField] float weaponRange = 2f;
8.     [SerializeField] float weaponDamage = 5f;
9.     public object currentWeaponConfig;
10.         void Start() {
11.        
12.         animator = GetComponent<Animator>();
13.  
14.      }
15.  
16.      public void Update() {
17.  
18.          bool isInRange = Vector3.Distance(transform.position, target.position) < weaponRange;
19.        
20.      }
21.     public void KnightHeroAttack() {
22.  
23.         animator.SetTrigger("KnightHeroAttack");
24.  
25.     }
26.     //Animation Event
27.     void OldHit() {
28.  
29.         Health healthComponent = target.GetComponent<Health>();
30.         healthComponent.TakeDamage(weaponDamage);
31.  
32.     }
33.     void Hit() {
34.  
35.      var hits = Physics.SphereCastAll(transform.position, 2.0f, transform.forward); //Collect objects in front of player
36.      Health nearestEnemy = null;
37.      float distanceCheck = 10000;
38.      foreach(var hit in hits) {
39.  
40.          if(hit.transform == transform) continue; //ignore self
41.          if(hit.distance > distanceCheck) continue;
42.          Health potentialEnemy = hit.transform.GetComponent<Health>();
43.          if(potentialEnemy) {
44.            
45.                nearestEnemy=potentialEnemy;
46.                distanceCheck=hit.distance;
47.          }
48.      }
49.  
50.      if(distanceCheck < currentWeaponConfig.GetRange()) return; //this should actually also account for no enemy found
51.      target = nearestEnemy.gameObject.transform;
52.      OldHit();
53. }
54.  
55.     }
56.  
57. }

 

your

currentWeaponConfig

is of type

object

which represents any kind of object (the base of every type in C#). Probably you want to specify the actual type of the variable in the first place like

public WeaponConfig currentWeaponConfig;

(Assuming that there is a class or struct named "WeaponConfig").
Or, if you have several different classes for such config but they share some methods like "GetRange()" you should make a base class or interface which every config class implements and use that as type for the variable.
If you have several WeaponConfig classes but not all of them should have GetRange() you need to box it:

float range = (currentWeaponConfig as RangedWeaponConfig)?.GetRange() ?? 0;

 

This my current code:

I've got rid of the errors but now the enemies aren't taking damage, I know it's only made to print the damage but it's not doing that and I can't see any errors.
