u3d常用代码小集合

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

var myTimer : float = 5.0;

function Update () {

if(myTimer > 0){

myTimer -= Time.deltaTime;

}

if(myTimer <= 0){

Debug.Log("GAME OVER");

}

}

06、物体在屏幕上移动

var speed : float = 5.0;

function Update () {

transform.Translate(Vector3(0,0,speed) * Time.deltaTime);

}

07、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));

}

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
