Timer - CS0029: Cannot implicitly convert type `float' to `bool'

I’m getting this error when trying to setup my timer (Assets/Scripts/ShroomScript.cs(47,25): error CS0029: Cannot implicitly convert type float' to bool’)

using UnityEngine;
using System.Collections;

public class ShroomScript : MonoBehaviour {

	private heroController player;
	public float timeLeft = 60f;




	// Use this for initialization
	void Start () {

		player = GameObject.FindGameObjectWithTag("Player").GetComponent<heroController>();

	
	}
	
	void OnTriggerEnter2D(Collider2D col) {

		if(col.CompareTag("Player")){

			AudioSource AS = col.GetComponent<AudioSource>();
			AS.PlayOneShot(AS.clip);
			Destroy(gameObject);
			if (player.curHealth <=4)
			{
				player.HealthIncrease(1);
			}	else if (player.curHealth >= 5) 
			{
				player.HealthIncrease(0);
			}
			player.shroomPower = true; 
//			timeLeft = 5;
				
		}


			
}
	void Update () 	{
		if(timeLeft > 0)
		{
			Debug.Log("Waiting"+timeLeft);
			timeLeft -= Time.deltaTime;
			if (timeLeft = 0)		
			{player.shroomPower = false;}

		}

	}

			
}

You’ve written the assignment operator ‘=’ instead of the equality operator ‘==’ in line 47.

It should be

if(timeLeft == 0)

However, please be aware that the timeLeft variable will most-likely not exactly hit the value 0.0f.

Maybe you’d rather wanna try

if(timeLeft <= 0)
