一旦能量被选择，就试着发射大炮

基本上我已经得到了一个项目，在unity中使用c#和设备Leap Motion开发一款游戏。我遇到的问题是，我有一个基本的能量条，它在0 - 100的范围内上下移动，当用户松开拳头时，我想使用选择的能量射击。我遇到的问题是，我无法想出一种方法来设置bool "shoot"为真释放拳头。

Controller m_leapController;
public GameObject CannonBarrel;
[Range(0, 100)] public float ballPower = 0f;
public bool increasing = true;
public bool shoot = false;

if (frame.Hands.Count >= 2)
    {
        Hand leftHand = GetLeftMostHand(frame);
        Hand rightHand = GetRightMostHand(frame);
        Vector3 handDiff = leftHand.PalmPosition.ToUnityScaled() - rightHand.PalmPosition.ToUnityScaled();
        Vector3 newRot = CannonBarrel.transform.localRotation.eulerAngles;
        float leftRightSpeed = handDiff.y * 5.0f;
        float handPitch = leftHand.Direction.Pitch + rightHand.Direction.Pitch * 0.5f; 
        newRot.x = 0;
        newRot.y = 90;
        newRot.z = 70 + -handPitch * 20.0f;
        shoot = true;
        // if closed fist...
        if (frame.Fingers.Count < 3)
        {
            leftRightSpeed = 0;
            shoot = false;
            if (increasing == true)
            {
                ballPower++;
                if (ballPower >= 100)
                {
                    increasing = false;
                }
            }
            else if (increasing == false)
            {
                ballPower--;
                if (ballPower <= 0)
                {
                    increasing = true;
                }
            }
        }
        else 
        {
            //Move left or right depending on hands height difference.
            transform.parent.rigidbody.velocity = transform.parent.right * leftRightSpeed;
            //Rotate the barrel
            CannonBarrel.transform.localRotation = Quaternion.Slerp(CannonBarrel.transform.localRotation, Quaternion.Euler(newRot), 0.1f);
        }
        if (shoot == true)
        {
            Debug.Log("fired");
            //add code here to spawn projectile
        }
    }

我希望这段代码对你有意义。所发生的一切是，如果你把拳头放在Leap传感器上方，球的力量会增加，直到你打到100，然后它会下降到0，以此类推，直到你松开拳头。我需要一种方法来将"射击"bool设置为true，一旦一个权力被选中，就像我目前做的那样，我只能在权力选择期间将其设置为true，或者在你握紧拳头之前将其设置为true。

    float leftRightSpeed = handDiff.y * 5.0f;
    float handPitch = leftHand.Direction.Pitch + rightHand.Direction.Pitch * 0.5f; 
    newRot.x = 0;
    newRot.y = 90;
    newRot.z = 70 + -handPitch * 20.0f;
    //shoot = true;
