Having trouble getting two scripts (involving triggers) to behave properly.

Unity Engine

Ok… so I have two scripts.

One that lets me push, and pull my object:

    using UnityEngine;
    using System.Collections;
    using System.Collections.Generic;
  
    public class Gravity : MonoBehaviour
    {
  
        public bool reverseForce = false;
  
        public float strength = 50f;
        public float strengthExponent = 1.1f;
        public bool scaleStrengthOnMass = false;
  
        public float range = 50f;
  
        public string targetTag = "";
        public List<Rigidbody> objectsInRange;
  
        private Transform _transform;
        private Rigidbody _rigidbody;
  
        void Start()
        {
            _transform = transform;
            if (GetComponent<Rigidbody>() != null)
            {
                _rigidbody = GetComponent<Rigidbody>();
            }
            else if (scaleStrengthOnMass)
            {
                Debug.LogError("Gravity - ScaleStrengthOnMass is on but rigidbody missing");
            }
            SphereCollider c = gameObject.AddComponent<SphereCollider>();
            c.radius = range;
            c.isTrigger = true;
        }
  
        void OnTriggerEnter(Collider c)
        {
            if (c.tag == targetTag)
            {
                if (c.GetComponent<Rigidbody>() != null)
                {
                    objectsInRange.Add(c.GetComponent<Rigidbody>());
                }
                else
                {
                    Debug.LogWarning("Gravity - Tagged object has no rigidbody");
                }
            }
        }
  
        void OnTriggerExit(Collider c)
        {
            if (c.tag == targetTag)
            {
                if (c.GetComponent<Rigidbody>() != null)
                {
                    objectsInRange.Remove(c.GetComponent<Rigidbody>());
                }
            }
        }
  
        void Update()
  
        {
            {
                {
                    if (!Input.GetMouseButton(0)) return;
                    float forceMultiplier;
                    Vector3 forceDirection;
                    foreach (Rigidbody a in objectsInRange)
                    {
                        forceMultiplier = (-strength / Mathf.Pow(Mathf.Max(Vector3.Distance(_transform.position, a.position), 1f), strengthExponent));
                        if (scaleStrengthOnMass)
                        {
                            if (GetComponent<Rigidbody>() != null)
                            {
                                forceMultiplier *= _rigidbody.mass;
                            }
                        }
  
                        if (reverseForce || Input.GetMouseButton(1))
  
                        {
                            forceMultiplier *= -1;
                        }
                        forceDirection = (a.position - _transform.position).normalized;
                        a.AddForce(forceDirection * forceMultiplier);
                    }
                }
  
                // void OnDrawGizmosSelected();
                {
                    //Gizmos.color = (new Color(0f,0f,1f));
                    //Gizmos.DrawWireSphere(_transform.position,range);
                }
            }
        }
    }

and my script that I need to trigger an event when it enters my trigger:

    using UnityEngine;
    using System.Collections;
  
    public class Switch : MonoBehaviour
    {
        GameObject Ball;
  
        // Use this for initialization
        void Start()
        {
  
        }
  
        // Update is called once per frame
        void Update()
        {
  
        }
  
        void OnTriggerEnter(Collider coll)
        {
            if (coll.gameObject.tag == "Ball")
                Debug.Log("Ball Entered! :)");     
              
        }
  
    }

Problem being when I have the Gravity script enabled it automatically triggers the event which is a problem. I have no idea why it’s doing this. Any ideas?

Use code tags please. This will look like this then easier to understand

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class Gravity : MonoBehaviour
{

public bool reverseForce = false;

public float strength = 50f;
public float strengthExponent = 1.1f;
public bool scaleStrengthOnMass = false;

public float range = 50f;

public string targetTag = "";
public List<Rigidbody> objectsInRange;

private Transform _transform;
private Rigidbody _rigidbody;

void Start()
{
_transform = transform;
if (GetComponent<Rigidbody>() != null)
{
_rigidbody = GetComponent<Rigidbody>();
}
else if (scaleStrengthOnMass)
{
Debug.LogError("Gravity - ScaleStrengthOnMass is on but rigidbody missing");
}
SphereCollider c = gameObject.AddComponent<SphereCollider>();
c.radius = range;
c.isTrigger = true;
}

void OnTriggerEnter(Collider c)
{
if (c.tag == targetTag)
{
if (c.GetComponent<Rigidbody>() != null)
{
objectsInRange.Add(c.GetComponent<Rigidbody>());
}
else
{
Debug.LogWarning("Gravity - Tagged object has no rigidbody");
}
}
}

void OnTriggerExit(Collider c)
{
if (c.tag == targetTag)
{
if (c.GetComponent<Rigidbody>() != null)
{
objectsInRange.Remove(c.GetComponent<Rigidbody>());
}
}
}

void Update()

{
{
{
if (!Input.GetMouseButton(0)) return;
float forceMultiplier;
Vector3 forceDirection;
foreach (Rigidbody a in objectsInRange)
{
forceMultiplier = (-strength / Mathf.Pow(Mathf.Max(Vector3.Distance(_transform.position, a.position), 1f), strengthExponent));
if (scaleStrengthOnMass)
{
if (GetComponent<Rigidbody>() != null)
{
forceMultiplier *= _rigidbody.mass;
}
}

if (reverseForce || Input.GetMouseButton(1))

{
forceMultiplier *= -1;
}
forceDirection = (a.position - _transform.position).normalized;
a.AddForce(forceDirection * forceMultiplier);
}
}

// void OnDrawGizmosSelected();
{
//Gizmos.color = (new Color(0f,0f,1f));
//Gizmos.DrawWireSphere(_transform.position,range);
}
}
}
}

and my script that I need to trigger an event when it enters my trigger:

using UnityEngine;
using System.Collections;

public class Switch : MonoBehaviour
{
GameObject Ball;

// Use this for initialization
void Start()
{

}

// Update is called once per frame
void Update()
{

}

void OnTriggerEnter(Collider coll)
{
if (coll.gameObject.tag == "Ball")
Debug.Log("Ball Entered! ");

}

}

There you go.
