unity + leapMotion 判断手指捏合（拇指和食指）

代码比较简单，我就不解释了

1.结构图如下：

2.代码如下：

using System.Collections;
using System.Collections.Generic;
using Leap;
using Leap.Unity;
using UnityEngine;

public class CcreateCube : MonoBehaviour {
    public HandModelBase leftHandModel;
    public HandModelBase rightHandModel;
    float twoFingerDistance = 0.07f;
    // 1.判断两个手指捏合
    // 2.判断两个手靠近
    // 3.生成cube

	// Update is called once per frame
	void Update () {
        if (leftHandModel.IsTracked)
        {
            Hand leftHand = leftHandModel.GetLeapHand();
            // float twoFingerDistance = 0.07f;
            if ((leftHand.Fingers[0].TipPosition - leftHand.Fingers[1].TipPosition).Magnitude < twoFingerDistance)
            {
                print("卧槽尼玛 你靠那么近干嘛！");
            }
        }
	}
}
