Unity 以Collider+Rigdbody達成攻擊物件偵測

AttackColliderController

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class AttackColliderController : MonoBehaviour {
	// 宣告公開變數 touchEnemy 為 TestEnemyHP List
	public List<GameObject> touchEnemyObject;
	public string targetEnemyTag = "Enemy";

	// 委託監聽
	public delegate void AttackEventHandler(GameObject go);  
	public event AttackEventHandler onAttackEnemy;  

	// 當 標籤為 目標敵人 物件 進入 碰撞區，將之加入 touchEnemy List
	void OnTriggerEnter (Collider otherEnemy) {
		if (otherEnemy.tag == targetEnemyTag) {
			// 判斷List中是否已有重複元素
			if (!touchEnemyObject.Contains(otherEnemy.gameObject) )
			{	
				touchEnemyObject.Add( otherEnemy.gameObject );
				OnAttackEnemy( otherEnemy.gameObject );
			}
		}
	}
	// 當 標籤為 目標敵人 物件 進入 碰撞區，將之移除 touchEnemy List
	/*void OnTriggerExit(Collider otherEnemy) {
		if (otherEnemy.tag == targetEnemyTag) {
			touchEnemyUnderAttackScript.Remove(otherEnemy.GetComponent<TestEnemyHP>());
		}
	}*/

	// 委託監聽的 攻擊函數，傳入要攻擊的敵人物件
	void OnAttackEnemy (GameObject go)
	{
		if (onAttackEnemy != null){
			onAttackEnemy (go);  
		}
	}

	void ClearEnemyList(){
		touchEnemyObject.Clear ();
	}
	// 當 碰撞物件停用，清除 touchEnemy List
	void OnDisable(){
		ClearEnemyList ();
	}
}

ListenAttackEvent

using UnityEngine;
using System.Collections;

public class ListenAttackEvent : MonoBehaviour {
	public GameObject attackColliderController;

	void Awake () {
		// 註冊監聽並呼叫OnAttack
		attackColliderController.GetComponent<AttackColliderController>().onAttackEnemy += OnAttack;
	}

	void OnAttack (GameObject go) {
		print (go.name);
	}
}
