Im trying to make so that when i click my mouse button i want to see if my two Boxcolliders are touching and make my bool true and if true log. The problem is if i click no matter what it keeps printing where am i going wrong?

using UnityEngine;
using System.Collections;

public class Thetrigger : MonoBehaviour {

	private bool triggered = false;
	public GameObject square1;
	
	void Update(){
		if (Input.GetMouseButtonDown (0)) {
			if (triggered |= true){
				Debug.Log ("bam");
			}
				}
			
	}

	void OnTriggerStay2D(Collider2D coll){
	if (gameObject.tag == "squarerow"){
						triggered = true;
		}
		else{
			triggered = false;
		}
		}
}

Thank you

Replace the OnTriggerStay method with:

void OnTriggerEnter2D(Collider2D coll){
     if (gameObject.tag == "squarerow"){
                         triggered = true;
         }
        
}

void OnTriggerExit2D(Collider2D coll){
     if (gameObject.tag == "squarerow"){
                         triggered = false;
         }
        
}

The OnTriggerStay only gets called when the trigger are colliding. Therefore, using the if-else within that method is wrong. The if-else refers to the other object having a tag of the name “squarerow”, not to object colliding or not.

EDIT: Also you need to fix the bug that you use gameObject.tag instead of coll.gameObject.tag. In both methods it should be:

 if (coll.gameObject.tag == "squarerow"){
                             triggered = false;
             }

Your syntax is incorrect. Assuming you meant to print bam when they’re not touching:

if (triggered |= true){

Should be:

if (triggered != true){
