对象池简介
对象池用来存储需要被大量创建和重复使用的对象，降低程序的IO访问，在合适的时间点创建和释放对象池，有助于提升程序整体性能。
以下创建了一个基本的对象池，实现创建多个池，从池中取对象，回收对象，以及回收回掉。
Demo截图如下：
工程目录：
创建对象池
void Start () {
ObjectPool.Ins.CreatePool (cubePool, () => { Debug.Log ("Create->" + cubePool.poolName + "->成功"); });
ObjectPool.Ins.CreatePool (spherePool, () => { Debug.Log ("Create->" + spherePool.poolName + "->成功"); });
ObjectPool.Ins.CreatePool (capsulePool, () => { Debug.Log ("Create->" + capsulePool.poolName + "->成功"); });
ObjectPool.Ins.CreatePool (cylinderPool, () => { Debug.Log ("Create->" + cylinderPool.poolName + "->成功"); });
}
从池中取出对象
void Update () {
if (Input.GetKeyDown (KeyCode.A)) {
ObjectPool.Ins.Spawn (cubePool, delegate () {
Debug.Log ("Spawn->" + cubePool.poolName + "->成功");
}).transform.localPosition = spawnPos;
}
if (Input.GetKeyDown (KeyCode.S)) {
ObjectPool.Ins.Spawn (spherePool, delegate () {
Debug.Log ("Spwn->" + spherePool.poolName + "->成功");
}).transform.localPosition = spawnPos;
}
if (Input.GetKeyDown (KeyCode.D)) {
ObjectPool.Ins.Spawn (capsulePool, () => {
Debug.Log ("Spawn->" + capsulePool.poolName + "->成功");
}).transform.localPosition = spawnPos;
}
if (Input.GetKeyDown (KeyCode.F)) {
ObjectPool.Ins.Spawn (cylinderPool, () => {
Debug.Log ("Spawn->" + cylinderPool.poolName + "->成功");
}).transform.localPosition = spawnPos;
}
}
回收不使用对象
IEnumerator RecyleObject () {
yield return new WaitForSeconds (2);
ObjectPool.Recyle (poolName, this.gameObject.name,RecyleAction);
}
//回收调用
void RecyleAction () {
Debug.Log ("开始回收");
this.GetComponent<Rigidbody> ().velocity = Vector3.one;
this.GetComponent<Rigidbody> ().angularVelocity = Vector3.zero;
this.transform.localPosition = Vector3.zero;
this.gameObject.SetActive (false);
}
工程里附有详细Demo,使用时只需要将Scripts下的 ObjectPool.cs 拖动到场景中，并在代码中配置一下池要初始化的对象即可，具体看Demo.
