OnTriggerEnter and Exit is not being checked

Unity Engine

Exactly what the title says, It doesn’t look like OnTriggerEnter and exit is being called i’m not sure whats going on.

using UnityEngine;
using System.Collections;

public class Sight : MonoBehaviour {

    public GameObject owner;
    private FighterController fc;
    void Start () {
    fc = owner.GetComponent <FighterController> ();
    }

    void OnTriggerEnter(Collider other) {
        if (other.gameObject.CompareTag ("fighter")) {
            fc.freemove = false;
            Debug.Log("found");
        }
    }
    void OnTriggerExit(Collider other){
        if (other.gameObject.CompareTag ("fighter")) {
            fc.freemove = true;
            Debug.Log("exited");
        }
    }

}

I have tried changing other.gameObject.CompareTag (“fighter”) to
other.tag == “fighter” and
other.gameObject.tag == “fighter”.

And i have also put Debug.Log(“—”) inside the body of OnTriggerEnter and is still not being called.
On the object with fighter tag i have tried checking the trigger box in collider component as well, still not working can you help me solve this problem thanks.

Just in case you ask, Yes i have set a fighter tag onto the object i want it to detect.

Are one or both colliders set to Kinematic=true?
Does OnCollisionEnter trigger?

Theres a nice overview at the bottom of this page Unity - Manual: Introduction to collision to see when what collision does trigger events. Maybe it could be helpful.

only one the objects has a rigidbody because the sight is a empty object

Well, please check the table I’ve mentioned (Collision action matrix) to take the guesswork out of it. There are just to many variations. :slight_smile:

I have tried giving sights object a rigid body and that didn’t work i don’t know why this is not detecting i have another scene with almost equal conditions which is working with triggerEnter. I think there’s something wrong with the script not the component because i have looked at the table and gave the sights object a rigid body collider and its still not detecting.

No, your script is correct. Two gameobjects with rigidbodys and trigger colliders will trigger the event.
I think you’re messing up with some invalid combinations of istrigger, kinematic, rigidbody, etc. and OnTrigger/OnCollision.

Problem solved i had to have a box collider on the sights object.

thanks for your help.
