My trigger does not detect my player

Question

My trigger does not detect my player.
My Trigger.cs file:

using UnityEngine;


public class Trigger : MonoBehaviour {

public Camera camera1;
public Camera camera2;
public GameObject panel;


 void OnTriggerEnter(Collider other)
{
    camera1.enabled = false;
    camera2.enabled = true;
    panel.SetActive(true);
    Debug.Log ("Entered-");
}

 void OnTriggerExit(Collider other)
{
    camera2.enabled = false;
    camera1.enabled = true;
    panel.SetActive(false);
  
}
private void Update()
{
    if(Input.GetKeyDown(KeyCode.DownArrow) || Input.GetKeyDown(KeyCode.S))
    {
        panel.SetActive(false);
        
    }
            }

}

Where I can start troubleshooting te issue?
Object on which the trigger script is sitting on.

The solution:
-- I created two colliders, and assigned one as a collider, the other (bigger) is a trigger.
-- I also had problems with the small triggers in the scene. The triggers were to small to be detected by my main player, althought they detected my "sphere" player object

Answer 1

You have to set IsTrigger to true on the BoxCollider. If this isn't set, it indicated that the box collider is only used for physics.

If you are trying to fire code when two objects collide, you need to use OnCollisionEnter, OnCollisionExit, OnCollisionStay

See the following documentation for more information:
