2D Collision not registering

Questions & Answers
1

I’m creating a 2D space shooter, and I have my Collision function in my Bullet Script

public void OnCollisionEnter2D(Collision2D col)
	{
		if (col.gameObject.tag.Equals("Enemy") || col.gameObject.tag.Equals ("Player"))
		{
			col.gameObject.GetComponent<Health>().TakeDamage(5);
			Debug.Log("Damage Taken");
			Destroy(col.gameObject);
		}    		
	}

And my Health script attached to Enemy

public class Health : MonoBehaviour
{
	public int health = 100;
	// Use this for initialization
	void Start()
	{
	}
	// Update is called once per frame
	void Update()
	{
		if (health <= 0)
		{
			Destroy(gameObject);
		}
	}
	public void TakeDamage(int amount)
	{
		health -= amount;
	}
}

But my bullets go straight through Enemy and don’t detect collision, i’ve tried layers, triggers and tags but to no avail, can someone point out my flaws?

I’m thinking the tag.Equals bit is what’s causing the bug.

Try writing the code like this

col.gameObject.tag == "Enemy" || col.gameObject.tag == "Player"
