动态进行静态批处理优化

public class Aab : MonoBehaviour {
GameObject[] allObjs;

void Start () {
    allObjs = new GameObject[this.transform.childCount];

    for (int i = 0; i < transform.childCount; i++) {
        //this.transform.GetChild (i).name = "TA" + i;
        allObjs[i]=this.transform.GetChild (i).gameObject;
    }
    StaticBatchingUtility.Combine(allObjs, this.gameObject);
}

}

此脚本挂在父物体上
