siaqodb , if it is empty , null

  
      Siaqodb siaqodb = DBManager.Instance.GetInstance ();

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;
            }

Parse Adding user unity

var user = new Parse.User(); user.set("username", "my name"); user.set("password", "my pass"); user.set("email", "email@example.com"); // other fields can be set just like with Parse.Object user.set("phone", "415-392-0202"); user.signUp(null, { success: function(user) { // Hooray! Let them use the app now. }, error: function(user, error) { // Show the error message somewhere and let the user try again. alert("Error: " + error.code + " " + error.message); } });

difference between Update and FixedUpdate

 Update
update in the amount of Framerate

 FixedUpdate
update in the amount of 24fps

unity - rigidbody arrow control by Keyboard

The value will be in the range -1...1 for keyboard and joystick input.

        horizontalMovement = Input.GetAxis("Horizontal") * Vector3.right * movementSpeed;
        verticalMovement = Input.GetAxis("Vertical") * Vector3.forward * movementSpeed;

        Vector3 movement = horizontalMovement + verticalMovement;

        rigidbody.AddForce(movement, ForceMode.Force);

unity - rigidbody rotate

var eulerAngleVelocity : Vector3 = Vector3 (0, 100, 0);
 function FixedUpdate () {
  var deltaRotation : Quaternion = Quaternion.Euler(eulerAngleVelocity * Time.deltaTime);
  rigidbody.MoveRotation(rigidbody.rotation * deltaRotation);
 }

unity - rigidbody move

 http://docs.unity3d.com/ScriptReference/Rigidbody.MovePosition.html

private var speed : Vector3 = Vector3 (3, 0, 0);
 function FixedUpdate () {
  rigidbody.MovePosition(rigidbody.position + speed * Time.deltaTime);
 }

easy gravity example

1- drag a 3Dobject->cube into sense

2- add script on the right side, component

3- write the script
