Unity3D常用代码集合

1、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");
        
        }
    
    }

2、检测输入
       
    function Update () {
     
    if(Input.GetButtonUp("Jump")){
     
    Debug.Log("We Have Hit the Space Bar!");
     
    }
     
    }
3、销毁对象
       
    function Start () {
     
    Destroy(gameObject.Find("Box"), 3);
     
    }
4、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);
     
    }
把代码拖入到空GameJect上，然后把Prefab拖入到公共变量上。
5、简易定时器
       
    var myTimer : float = 5.0;
     
    function Update () {
     
    if(myTimer > 0){
     
    myTimer -= Time.deltaTime;
     
    }
     
    if(myTimer <= 0){
     
    Debug.Log("GAME OVER");
     
    }
     
    }
6、物体在屏幕上移动
       
    var speed : float = 5.0;
     
    function Update () {
     
    transform.Translate(Vector3(0,0,speed) * Time.deltaTime);
     
    }
7、钢体向目标处移动
       
    //Basic force to move a rigidbody object
     
    var power : float = 500.0;
     
    function Start () {
     
    rigidbody.AddForce(Vector3(0,0,power));
     
    }
8、碰撞然后转到下一场景
       
    function OnCollisionEnter (Collision : Collision) {
     
    if(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！
