物體移動

1. translate(X,Y,Z)移動

void Update () {
  float x=Input.GetAxis("Horizontal") * Time.deltaTime * speed;
  float z= Input.GetAxis("Vertical") * Time.deltaTime * speed;
  transform.Translate(x, 0,z);
}

2. 剛體加力移動

//按下鼠標左鍵
if (Input.GetButtonDown("Fire1"))
{
  //新建預制物體，預制對象，位置，旋轉速度
  Transform tf=Instantiate(newtf, transform.position, transform.rotation);
  //剛體加力
  tf.GetComponent<Rigidbody>().AddForce(transform.TransformDirection(Vector3.forward)*force);
}
        

3. 設置剛體速度

gameObject.GetComponent<Rigidbody>().velocity=new Vector3(0,y,0);

物體旋轉

//檢測鍵盤輸入
if (Input.GetKey(KeyCode.Q))
{
    //物體旋轉
    //左右旋轉，即以y軸旋轉；
    //Space.Self以自身坐標軸旋轉，Space.World以世界坐標軸旋轉
    transform.Rotate(0, -1*rotateSpeed * Time.deltaTime, 0, Space.Self);
}
if(Input.GetKey(KeyCode.E))
{
    transform.Rotate(0,  rotateSpeed*Time.deltaTime, 0, Space.Self);
}

查找物體

//fps為name,text為類型
//fps顯示方式是欠妥的
GameObject.Find("fps").GetComponent<Text>().text =
   "FPS " + (1 / Time.deltaTime).ToString().Substring(0,2);

//尋找腳本組件
GameObject.FindGameObjectWithTag("MainCamera")
                .GetComponent<ClassName>().enabled = false;

繪制按鈕

private void OnGUI(){
    if (GUI.Button(new Rect((float)(Screen.width*0.3),
            (float)(Screen.width*0.1),
            (float)(Screen.width*0.4),
            (float)(Screen.width*0.05)),
        "退出")){
        //退出程序
        Application.Quit();
    }
    if (GUI.Button(new Rect((float)(Screen.width*0.3),
            (float)(Screen.width*0.2),
            (float)(Screen.width*0.4),
            (float)(Screen.width*0.05)),
        "重新開始")){
        //加載場景
        SceneManager.LoadScene("1");
    }
    
}
