一些常用UNITY3D代码

01、基本碰撞检测代码
function OnCollisionEnter(theCollision : Collision){
 
 if(theCollision.gameObject.name == "Floor"){
 
  Debug.Log("Hit the floor");
 
   }else if(theCollision.gameObject.name == "Wall"){
 
  Debug.Log("Hit the wall");
  
     }

  }
02、检测输入
function Update () {
          if(Input.GetButtonUp("Jump")){
              Debug.Log("We Have Hit the Space Bar!");
           }
      }
03、销毁对象

function Start () {

 Destroy(gameObject.Find("Box"), 3);

}

04、实例来创建对象

//Simple Instantiation of a Prefab at Start

var thePrefab : GameObject;

function Start () {

var instance : GameObject = Instantiate(thePrefab, transform.position, transform.rotation);

}

建立JAVA，把代码拖入到空GameJect上，然后把Prefab拖入到公共变量上，就可以了

05、简易定时器

1. var myTimer : float = 5.0;
2.  
3. function Update () {
4.  if(myTimer > 0){
5.   myTimer -= Time.deltaTime;
6.  }
7.  if(myTimer <= 0){
8.   Debug.Log("GAME OVER");
9.  }
10. }

06、物体在屏幕上移动

1. var speed : float = 5.0;
2.  
3. function Update () {
4.  transform.Translate(Vector3(0,0,speed) * Time.deltaTime);
5. }

07、钢体向目标处移动

//Basic force to move a rigidbody object

1. var power : float = 500.0;
2.  
3. function Start () {
4.  rigidbody.AddForce(Vector3(0,0,power));
5. }

08、碰撞然后转到下一场景

• function OnCollisionEnter (myCollision : Collision) {
•  if(myCollision.gameObject.name == "Floor"){
•   Application.LoadLevel(myLevel);
•  }
• }
• floor---被动碰撞的的纲体
• 把代码拉到主动纲体上
• 然后

  场景设置:file----build seting----对话框,然后把当前场景拖里,然后把下一场景拖里,测试OK
