public bool isTrigger;


Is the collider a trigger?

A trigger doesn't register a collision with an incoming Rigidbody. Instead, it sends OnTriggerEnter, OnTriggerExit and OnTriggerStay message when a rigidbody enters or exits the trigger volume.

using UnityEngine;

public class Example : MonoBehaviour { Collider m_ObjectCollider;

void Start() { //Fetch the GameObject's Collider (make sure they have a Collider component) m_ObjectCollider = GetComponent<Collider>(); //Here the GameObject's Collider is not a trigger m_ObjectCollider.isTrigger = false; //Output whether the Collider is a trigger type Collider or not Debug.Log("Trigger On : " + m_ObjectCollider.isTrigger); }

void OnMouseDown() { //GameObject's Collider is now a trigger Collider when the GameObject is clicked. It now acts as a trigger m_ObjectCollider.isTrigger = true; //Output to console the GameObject’s trigger state Debug.Log("Trigger On : " + m_ObjectCollider.isTrigger); } }
