Line 22 —> enemy.DamageEnemy(PlayerStats.instance.bulletDamage);
Any idea how I can convert it to a float? Thanks!

Script:

using UnityEngine;
using System.Collections;

public class DamageEnemyCollision : MonoBehaviour
{

	private Enemy enemy = null;

	void Start()
	{
		if (GameObject.FindGameObjectsWithTag("Enemy") != null)
		{
			GameObject go = GameObject.FindGameObjectsWithTag("Enemy")[0];
			enemy = go.GetComponent<Enemy>();
		}
	}

	void OnCollisionEnter2D(Collision2D coll)
	{
		if ((coll.gameObject.tag == "Enemy") && (enemy != null))
		{
			enemy.DamageEnemy(PlayerStats.instance.bulletDamage);
		}
	}
}

If you need it
Enemy Script:

using UnityEngine;
using System.Collections;

public class Enemy : MonoBehaviour {

	[System.Serializable]
	public class EnemyStats {
		public int maxHealth = 100;

		public int scoreDrop = 10;

		private int _curHealth;
		public int curHealth
		{
			get { return _curHealth; }
			set { _curHealth = Mathf.Clamp (value, 0, maxHealth); }
		}

		public void Init()
		{
			curHealth = maxHealth;
		}
	}
	
	public EnemyStats stats = new EnemyStats();

	[Header("Optional: ")]
	[SerializeField]
	private StatusIndicator statusIndicator;

	void Start()
	{
		stats.Init ();

		if (statusIndicator != null)
		{
			statusIndicator.SetHealth (stats.curHealth, stats.maxHealth);
		}
	}
	
	public void DamageEnemy (int damage) {
		stats.curHealth -= damage;
		if (stats.curHealth <= 0)
		{
			GameMaster.KillEnemy (this);
		}

		if (statusIndicator != null)
		{
			statusIndicator.SetHealth (stats.curHealth, stats.maxHealth);
		}
	}
}

Casting:

enemy.DamageEnemy((int)(PlayerStats.instance.bulletDamage));
