查找
GameObject-find
//must sure the thing or things in the hierachy then you can find
GameObject obj = GameObject.Find("");//查找名字为“”的物体
GameObject obj = GameObject.FindGameObjectWithTag("");//查找一个物体标签为“”
GameObject[] objs = GameObject.FindGameObjectsWithTag("");//查找所有物体标签为“”的，且放置到数组中
for (int i = 0; i < objs.Length; i++)
{
Debug.Log(objs[i].name);
}
克隆
GameOject-clone
public GameObject cubeobj;//克隆母本
GameObject obj = GameObject.Instantiate(cubeobj, cubeobj.transform.position, cubeobj.transform.rotation) as GameObject;//原地克隆Start函数里
GameObject obj = GameObject.Instantiate(cubeobj, new Vector3(1, 2, 3), cubeobj.transform.rotation) as GameObject;
Instantiate (prefab, Vector3(2.0, 0, 0), Quaternion.identity);
prefab是被克隆的对象， 第二个变量是克隆体生成的位置，第三个变
量表示该生成的克隆不旋转。
对第三个变量详解：
Quaternion 四元数，用来表示旋转
销毁
GameObject- Destroy
public float time = 1;
Destroy(gameObject, time);//gameObject为挂脚本的物体
Prefab-将Hierarchy里的物体拖拽到Assets面板即可
