siaqodb , if it is empty , null

  
      Siaqodb siaqodb = DBManager.Instance.GetInstance ();

        if(siaqodb!=null){
            showSiaqoDB();
        }

activeInHierarchy , 看有沒有被打開

Object.Instantiate

initiate position:

 // Instantiates 10 copies of prefab each 2 units apart from each other

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public Transform prefab;
    void Start() {
        for (int i = 0; i < 10; i++) {
            Instantiate(prefab, new Vector3(i * 2.0F, 0, 0), Quaternion.identity);
            i++;
        }
    }
}

Instantiate is most commonly used to instantiate projectiles, AI Enemies, particle explosions or wrecked object replacements.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public Rigidbody projectile;
    void Update() {
        if (Input.GetButtonDown("Fire1")) {
            Rigidbody clone;
            clone = Instantiate(projectile, transform.position, transform.rotation) as Rigidbody;
            clone.velocity = transform.TransformDirection(Vector3.forward * 10);
        }
    }
}

            GameObject item;
            I18nData holder = (I18nData)Resources.Load("I18nDataHolder", typeof(I18nData));
            if (holder.lang == "CN") {
                item = Instantiate(Resources.Load("Prefab/LitemButton1CN"))as GameObject;
            }
            else if (holder.lang == "EN") {
                item = Instantiate(Resources.Load("Prefab/LitemButton1EN"))as GameObject;
            }
            else if (holder.lang == "JP") {
                item = Instantiate(Resources.Load("Prefab/LitemButton1JP"))as GameObject;
            }
            else{
                item = Instantiate(Resources.Load("Prefab/ItemBubble"))as GameObject;
            }
