本文介绍了一个Unity游戏中的玩家攻击机制实现方法。通过控制攻击冷却时间并利用输入按键触发攻击动作，确保了攻击频率的合理性。文章详细展示了如何通过计算目标与玩家之间的距离和方向来判断是否造成伤害。

using UnityEngine;
using System.Collections;

public class PlayerAttack : MonoBehaviour {
	public GameObject target;
	public float attackTimer;
	public float coolDown;
	
	// Use this for initialization
	void Start () {
		attackTimer = 0;
		coolDown = 2.0f;
	}
	
	// Update is called once per frame
	void Update () {
		// Edge check
		if (attackTimer > 0)
			attackTimer -= Time.deltaTime;
		
		if (attackTimer < 0)
			attackTimer = 0;
		
		if (Input.GetKeyUp(KeyCode.F)) {
			// Limit the rate of attack
			if (attackTimer == 0) {
				Attack();
				attackTimer = coolDown;
			}
		}
	}
	
	private void Attack () {
		// If two objects is the same direction and close enough, then enable damage.
		float distance = Vector3.Distance(target.transform.position, transform.position);
		
		Vector3 dir = (target.transform.position - transform.position).normalized;
		
		float direction = Vector3.Dot(dir, transform.forward);
		
		if (distance < 2.5f) {
			if (direction > 0) {
				EnemyHealth eh = (EnemyHealth)target.GetComponent("EnemyHealth");
				eh.AddjustCurrentHealth(-10);
			}
		}
	}
}
