Bullet subtracting damage from enemy health

Questions & Answers
1

So like I’ve spent the last hour searching around for how to fix this, and dispite writing down some peoples codes word for word character for character I can not figure this out.

So basically I have a bullet script, that makes the object move forward based on the objects public float, and a damage int to be applied to enemies.

public class bullet : MonoBehaviour {

public int damage;
public float velocity;

void Update () {
	// bullet movement
	transform.position += transform.right * Time.deltaTime * velocity;
}
	// bullet dealing damage, then destroying itself
	void OnCollisionEnter2D(Collision2D coll) {
	if (coll.gameObject.tag == "Enemy")
		coll.gameObject.GetComponent<EnemyHealth>().Health = Health - damage;
	Destroy (gameObject);

}

}

it then in theory applies this damage effect to my enemy script:

public class EnemyHealth : MonoBehaviour {

public int Health;

void Update () {
	if (Health => 0f)
	{
		Destroy (gameObject);
	}
}
}

The bullet moves correctly and disapears on hit, but when I have the code to adjust the enemies health I get the error:
EnemyHealth.cs(10,7) error CS1660: Cannot convert ‘lambda’ to non-delegate type ‘bool’

There isn’t a single bool anywhere in this code so I have no idea what it’s talking about.

I also get the error:
bullet.cs(17,57): error CS0103: The name ‘Health’ does not exist in the current context

so yeah I’m at a loss, any ideas?

Edit:
Side note, I fixed the error “EnemyHealth.cs(10,7) error CS1660: Cannot convert ‘lambda’ to non-delegate type ‘bool’” simply by changing the “health <= 0” to health < 1" It basically works the same since it’s an int not a float, so that problem is fixed at least.

This can be made very easy thanks to the API SendMessage. I created a game like this too, so this should do it

bullet.cs

 public int damage;
 public float velocity;
 void Update () {
     // bullet movement
     transform.position += transform.right * Time.deltaTime * velocity;
 }
     // bullet dealing damage, then destroying itself
     void OnCollisionEnter2D(Collision2D coll) {
     if (coll.gameObject.tag == "Enemy")
         coll.gameObject.SendMessage("hit", damage);
     Destroy (gameObject);
 }

EnemyHealth.cs

 public int Health;
 
    void hit(int damage){
        Health -= damage;
        Debug.Log("Hit");
    }
