Unity 常用代码

来源：互联网发布：局域网控制上网软件编辑：程序博客网时间：2024/05/01 23:27

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

09.\球体滚动（角）：
var speed = 0.00;
var force = 0.00;

function FixedUpdate ()
{
    var oldAngle = Camera.main.transform.localEulerAngles.x;
    Camera.main.transform.localEulerAngles.x = 0;
    var spin = Camera.main.transform.TransformDirection(Vector3(Input.GetAxis("Vertical") * speed, 0, -Input.GetAxis("Horizontal") * speed));
    Camera.main.transform.localEulerAngles.x = oldAngle;
    rigidbody.AddTorque((spin - rigidbody.angularVelocity) * force);
}
