Unity collision not detected

Question

I'm making a Unity game, in which player should push all "Enemy" object from the plane. So to be able to count the number of fallen objects I want to generally be able to tell when a collision occurred between the red cube and every other cube. The script seems to not detect a collision, how to fix it?

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

public class Collide : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {

    }

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

    }
    void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.tag == "Enemy")
            Destroy(gameObject);
                Debug.Log("Hit Occured");
    }

}

did you set the collider as a trigger? have you checked the trigger/collider chart? did you mean trigger or did you want collision? — BugFinder

I want to see a Debug.Log message after a collision between the red cube and every other cube — Atanas

you need OnCollisionEnter

void OnCollisionEnter(Collision collision){

}

because your colliders aren't triggers.

I dont think so, because he want the red cube to push the others

BugFinder Over a year ago

True, I half missed that, but then you could want to add velocity by hand or something like it runs away or something..

Thanks, that solves a problem and also leads to another one. Now I receive from the console: The name 'other' does not exist in the current context. How to rewrite other.gameObject.tag == "Enemy" so that other means the object of collision?

Daahrien Over a year ago

now you must use "collision.", maybe its collision.collider.gameObject.tag?

You need to implement OnCollisionEnter(Collision collision) not OnTriggerEnter(Collider other) or check BoxCollider IsTrigger checkbox

There are 3 things to be checked 1. The OnCollisionEnter should be used in place of OnTriggerEnter 2. isTrigger checkbox should be enabled so that the event is triggered when the both bodies collide with other . 3. The most important thing which no one has mentioned is the tags given to the gameobject or the enemies because we need to define the gameobject that event should be triggered when hit to the specific body because the gameobject contains the collider and can collide to any wall or something so you need to define the tags properly
