Question by MrAwesome343 · Jun 20, 2016 at 02:13 AM · triggerscripting beginnerbooleantag

How can I check if an object has entered a trigger with a script attached to a different object?

If I have the player walk into something that is a trigger with a certain tag, how can I set a boolean to true and check that it's true with a script attached to a different object?

Grab a reference of it and check the variable. If you set it to true on the player and it's a public variable then you can grab it from a reference script by any from in the scene.

 public class Player : MonoBehaviour
 {
     public bool EnteredTrigger;
 
     public void OnTriggerEnter(Collider other)
     {
         if (other.tag == /*the tag*/)
             EnteredTrigger = true;
     }
 }
 
 public class OtherScript : MonoBehaviour
 {
     private GameObject m_Player;
     private void Start()
     {
         m_Player = GameObject.FindWithTag("Player");
     }
 
     private void Update()
     {
         if (m_Player.GetComponent<Player>().EnteredTrigger)
             //Do whatever
     }
 }

And for more accurate, you can also create a variable for the object generating the collision

 public class Player : $$anonymous$$onoBehaviour
  {
      public bool EnteredTrigger;
      public GameObject CollisionWith;  
  
      public void OnTriggerEnter(Collider other)
      {
          if (other.tag == /*the tag*/)
              EnteredTrigger = true;
              CollisionWith = other.gameObject;
      }
  }     
  public class OtherScript : $$anonymous$$onoBehaviour
  {
      private GameObject m_Player;
      private void Start()
      {
          m_Player = GameObject.FindWithTag("Player");
      }     
      private void Update()
      {
          if (m_Player.GetComponent<Player>().EnteredTrigger)
              { 
              //Do whatever
               }
      }
  }
