Check if any array item is true

I have a script referencing a script called WeightedButton, which has a public boolean called isEnabled.

What I need to do is check to see if ANY of the items in said array have an isEnabled value of true, and to run some code.

Everything I have found online so far points to checking if all are true, I need to find out if any of them are true.

The current code for the main script is laid out like so:
Barrier.cs

Code (CSharp):

1. using UnityEngine;
2.  
3. public class Barrier : MonoBehaviour
4. {
5.  
6.     public enum State
7.     {
8.         Active,
9.         Inactive,
10.     }
11.  
12.     public State state;
13.     public WeightedButton[] buttons;
14.  
15.     void Update()
16.     {
17.         if (state == State.Active)
18.         {
19.             MeshRenderer meshObject = GetComponent<MeshRenderer>();
20.             meshObject.enabled = true;
21.             BoxCollider meshCollider = GetComponent<BoxCollider>();
22.             meshCollider.enabled = true;
23.         }
24.         else
25.         {
26.             MeshRenderer meshObject = GetComponent<MeshRenderer>();
27.             meshObject.enabled = false;
28.             BoxCollider meshCollider = GetComponent<BoxCollider>();
29.             meshCollider.enabled = false;
30.         }
31.  
32.     }
33.  
34.     public void FixedUpdate()
35.     {
36.         foreach (WeightedButton wb in buttons)
37.         {
38.             if (wb.isEnabled)
39.             {
40.                 state = State.Inactive;
41.             }
42.             if (!wb.isEnabled)
43.             {
44.                 state = State.Active;
45.             }
46.         }
47.     }
48. }

WeightedButton.cs

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class WeightedButton : MonoBehaviour
5. {
6.     public bool isEnabled;
7.     public GameObject buttonObject;
8.     public Vector3 buttonOrigin = new Vector3(0f, 0.1f, 0f);
9.     public Vector3 buttonTarget = new Vector3(0f, 0.05f, 0f);
10.     public float moveSpeed;
11.  
12.     void OnCollisionEnter(Collision other)
13.     {
14.         StartCoroutine(MoveDown(buttonTarget));
15.  
16.         if (other.gameObject.tag == "Box" || other.gameObject.tag == "Player")
17.         {
18.             isEnabled = true;
19.         }
20.     }
21.  
22.     void OnCollisionExit(Collision other)
23.     {
24.         StartCoroutine(MoveUp(buttonOrigin));
25.  
26.         if (other.gameObject.tag == "Box" || other.gameObject.tag == "Player")
27.         {
28.             isEnabled = false;
29.         }
30.     }
31.  
32.     IEnumerator MoveDown(Vector3 target)
33.     {
34.         while (buttonObject.transform.localPosition != target)
35.         {
36.             buttonObject.transform.localPosition = Vector3.MoveTowards(buttonObject.transform.localPosition, target, moveSpeed * Time.deltaTime);
37.             yield return 0;
38.         }
39.     }
40.  
41.     IEnumerator MoveUp(Vector3 origin)
42.     {
43.         while (buttonObject.transform.localPosition != origin)
44.         {
45.             buttonObject.transform.localPosition = Vector3.MoveTowards(buttonObject.transform.localPosition, origin, moveSpeed * Time.deltaTime);
46.             yield return 0;
47.         }
48.     }
49. }

 

Anyone?

 

I'm not sure what's causing you confusion, to be honest.

This will return true if any of the buttons in the array are enabled

Code (CSharp):

1. bool AnyButtonEnabled()
2. {
3.     foreach(var button in buttons)
4.         if (button.isEnabled)
5.             return true;
6.          
7.     return false;
8. }

So, I guess, your use case:

Code (CSharp):

1. void FixedUpdate()
2. {
3.     state = AnyButtonEnabled() ? State.Active : State.Inactive;
4. }

 

Iterate through the collection until you find one that is true. If you get to the end of the collection then none of them are true.

 

Code (CSharp):

1. buttons.Any(b => b.isEnabled)
