VR飛機項目2016/9/19-25獲取按鍵輸入（虛擬按鍵等）

     通過虛擬搖桿控制飛機的左右上下，這次沒有使用控制rotation上的xyz3個軸的值來實現，而是通過每幀增加一個增量來實現

mainRot = this.transform.rotation;.
AddRot.eulerAngles = new Vector3 (pitch, yaw, -roll);
mainRot *= AddRot;
transform.rotation = Quaternion.Lerp (transform.rotation, mainRot, Time.fixedDeltaTime * RotationSpeed);

<span style="white-space:pre">	</span>public void AxisControl (Vector2 axis)
	{
		if (SimpleControl) {
			LimitAxisControl.y = LimitAxisControl.x;	
		}
		roll = Mathf.Lerp (roll, Mathf.Clamp (axis.x, -LimitAxisControl.x, LimitAxisControl.x) * SpeedRoll, Time.deltaTime);
		pitch = Mathf.Lerp (pitch, Mathf.Clamp (axis.y, -LimitAxisControl.y, LimitAxisControl.y) * SpeedPitch, Time.deltaTime);
	}

<span style="white-space:pre">	</span>public void TurnControl (float turn)
	{
		yaw += turn * Time.deltaTime * SpeedYaw;
	}

flight.AxisControl (new Vector2 (Input.GetAxis ("Mouse X"), Input.GetAxis ("Mouse Y")));
flight.TurnControl(Input.GetAxis("VirtualAxisX"));
flight.TurnControl (Input.GetAxis ("Horizontal"));

如果想要固定某個軸，不讓在這個軸上旋轉，可以以下代碼實現，實現固定某個軸

if (SimpleControl) {
  Quaternion saveQ = mainRot;    <span style="color:#009900;">//先用saveQ記錄下來這一幀的Quaternion
 //再記錄下這一幀的angle</span>
  Vector3 fixedAngles = new Vector3 (mainRot.eulerAngles.x, mainRot.eulerAngles.y, mainRot.eulerAngles.z);

  if(FixedX)   <span style="color:#009900;">//bool值，如果固定X軸，就讓angle對應的值爲1</span>
  fixedAngles.x = 1;
  if(FixedY)
  fixedAngles.y = 1;
  if(FixedZ)
  fixedAngles.z = 1;
 <span style="color:#009900;">//算出固定軸以後的Quaternion，然後讓物體從現在的Quaternion旋轉到固定某個軸以後的Quaternion</span>
  saveQ.eulerAngles = fixedAngles;

  mainRot = Quaternion.Lerp (mainRot, saveQ, Time.fixedDeltaTime * 2);
  }

獲取虛擬按鍵的方法

public void DetectPressedKeyOrButton()
    {
        foreach (KeyCode kcode in Enum.GetValues(typeof(KeyCode)))
        {
            if (Input.GetKeyDown(kcode))
            {
                Debug.Log("KeyCode down: " + kcode);
            }
        }
    }

使用了剛體的子彈，想讓子彈朝目標有偏差的設計，可以用以下方法

Vector3spread = newVector3(Random.Range(-Spread, Spread), Random.Range(-Spread, Spread), Random.Range(-Spread, Spread)) / 100;
Vector3 direction = this.transform.forward + spread;
GameObject bullet = (GameObject)Instantiate(Missile, missileposition, missilerotate);
bullet.transform.forward = direction;
