之前发了缓存池的用法，那么索性把对象池也写一个把。
首先是Unity布置：
代码直接给“Main Camera”
预制体添加刚体：也就是要发射的子弹。
Poolable代码：
public class Poolable : MonoBehaviour
{
public string key;
public bool isPooled;
}
POOL代码：
public class POOLc : MonoBehaviour
{
const string PoolKey = "";
[SerializeField]//序列化域,可以序列化非公有非静态域用[SerializeField]属性标记。不可以序列化静态域/不可以序列化属性 序列化的类型有：
//- All classed inheriting from UnityEngine.Object, for example Gameobject, Commponent, MonoBehaviour, Texture2D, AnimationClip.. - All basic data types like int, string, float, bool. - Some built in types like Vector2, Vector3, Vector4, Quaternion, Matrix4x4, Color, Rect, Layermask.. - Arrays of a serializable type
//- 所有继承自UnityEngine.Object的类，例如GameObject,Component,MonoBehaviour,Texture2D,AnimationClip..- 所有基本类型像int,string,float,bool.- 一些内建类型像Vector2,Vector3,Vector4,Quaternion,Matrix4x4,Color,Rect,Layermask..- 一个序列化类型的Array（数组）
GameObject prefab;
List<Poolable> instances = new List<Poolable>();
public Transform Mytrans;
bool isFire = false;
Poolable obj;
void Start()
{
if (GameObjectPoolController.AddEntry(PoolKey, prefab, 5, 10))
Debug.Log("预填充池");
else
Debug.Log("池已配置");
}
void Update()
{
if (Input.GetMouseButtonDown(0))
{
obj = GameObjectPoolController.Dequeue(PoolKey);
obj.gameObject.SetActive(true);
instances.Add(obj);
isFire = true;
}
if (instances.Count > 1)
{
Poolable obj = instances[0];
instances.RemoveAt(0);
GameObjectPoolController.Enqueue(obj);
}
if (isFire)
{
obj.GetComponent<Rigidbody>().velocity = new Vector3(0,0,-100);
obj.transform.position = Mytrans.position;
obj.transform.forward = Mytrans.forward;
isFire = false;
}
}
}
PoolData代码：
public class PoolData
{
public GameObject prefab;//预设
public int maxCount;//变量最大个数
public Queue<Poolable> pool;//预填充列
}
public class GameObjectPoolController : MonoBehaviour
{
//单例
static GameObjectPoolController Instance
{
get
{
if (instance == null)
CreateSharedInstance();
return instance;
}
}
static GameObjectPoolController instance;
static Dictionary<string, PoolData> pools = new Dictionary<string, PoolData>();
void Awake()
{
if (instance != null && instance != this)
Destroy(this);
else
instance = this;
}
//设置储存最大值
public static void SetMaxCount(string key, int maxCount)
{
if (!pools.ContainsKey(key))
return;
PoolData data = pools[key];
data.maxCount = maxCount;
}
//入仓
public static bool AddEntry(string key, GameObject prefab, int prepopulate, int maxCount)
{
if (pools.ContainsKey(key))
return false;
PoolData data = new PoolData();
data.prefab = prefab;
data.maxCount = maxCount;
data.pool = new Queue<Poolable>(prepopulate);
pools.Add(key, data);
for (int i = 0; i < prepopulate; ++i)
Enqueue(CreateInstance(key, prefab));
return true;
}
//清仓
public static void ClearEntry(string key)
{
if (!pools.ContainsKey(key))
return;
PoolData data = pools[key];
while (data.pool.Count > 0)
{
Poolable obj = data.pool.Dequeue();
GameObject.Destroy(obj.gameObject);
}
pools.Remove(key);
}
internal static void Enqueue(List<Poolable> instances)
{
throw new NotImplementedException();
}
//入队
public static void Enqueue(Poolable sender)
{
if (sender == null || sender.isPooled || !pools.ContainsKey(sender.key))
return;
PoolData data = pools[sender.key];
if (data.pool.Count >= data.maxCount)
{
GameObject.Destroy(sender.gameObject);
return;
}
data.pool.Enqueue(sender);
sender.isPooled = true;
sender.transform.SetParent(Instance.transform);
sender.gameObject.SetActive(false);
}
//出队
public static Poolable Dequeue(string key)
{
if (!pools.ContainsKey(key))
return null;
PoolData data = pools[key];
if (data.pool.Count == 0)
return CreateInstance(key, data.prefab);
Poolable obj = data.pool.Dequeue();
obj.isPooled = false;
return obj;
}
// 创建共享实例 主要是创建一个不销毁的父物体
static void CreateSharedInstance()
{
GameObject obj = new GameObject("GameObject Pool Controller");
DontDestroyOnLoad(obj);
instance = obj.AddComponent<GameObjectPoolController>();
}
static Poolable CreateInstance(string key, GameObject prefab)
{
GameObject instance = Instantiate(prefab) as GameObject;
Poolable p = instance.AddComponent<Poolable>();
p.key = key;
return p;
}
}
