Unity结合Vuforia虚拟按键实现AR机械仿真动画效果

零、最终效果

待上传

一、资源准备

1、Vuforia

Vuforia版本不能高于10.17.4（往上的版本虚拟按键功能被删除）

2、Unity

Unity版本必须要高于2022.3.x，不然使用Vuforia插件时会出现bug

二、主要内容

1、添加虚拟按钮

在这里插入图片描述

2、为虚拟按钮设置名字

在这里插入图片描述
注意：当一个图片中包含多个按钮时，需要为按钮设置不同的名字，否则会出现bug

3、为按钮添加按下和释放时触发的事件

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Vuforia;public class NewBehaviourScript : MonoBehaviour
{//获取关联按钮public VirtualButtonBehaviour virtualButton;// Start is called before the first frame updatevoid Start(){virtualButton.RegisterOnButtonPressed(ButtonPress);virtualButton.RegisterOnButtonReleased(ButtonReleased);}private void ButtonReleased(VirtualButtonBehaviour obj){throw new NotImplementedException();}private void ButtonPress(VirtualButtonBehaviour obj){print("虚拟按钮被按下");}// Update is called once per framevoid Update(){}
}

4、添加捕捉到图片和丢失图片时触发的事件

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Vuforia;public class NewBehaviourScript : MonoBehaviour
{//获取图片捕捉相关脚本public DefaultObserverEventHandler machineObserverEvent;// Start is called before the first frame updatevoid Start(){machineObserverEvent.OnTargetFound.AddListener(IsFound);machineObserverEvent.OnTargetLost.AddListener(IsLost);}private void IsLost(){print("丢失图片");}private void IsFound(){print("捕捉到图片");}// Update is called once per framevoid Update(){}
}

5、添加自己的识别图片数据库

在这里插入图片描述

将下载的包导入Unity中

6、导出过程遇到的bug及解决方法

bug:
Manifest merger failed : uses-sdk:minSdkVersion 22 cannot be smaller than version 23 declared in library [:VuforiaEngine:] C:\Users\龚子亦.gradle\caches\transforms-3\5e9057ea50ce3b6971d5e4ed2fb08fbe\transformed\VuforiaEngine\AndroidManifest.xml as the library might be using APIs not available in 22 See the Console for details.
解决方法:

三、完整代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Vuforia;public class Move : MonoBehaviour
{[Header("捕捉图片相关")]public GameObject machine;public DefaultObserverEventHandler machineObserverEvent;[Header("播放动画相关")]public VirtualButtonBehaviour play;public Animator machineAnimator;//判断是否播放动画private bool isPress = false;[Header("拆解零件相关相关")]public VirtualButtonBehaviour move;private bool isSplit=false;// Start is called before the first frame updatevoid Start(){//添加播放按钮按下时 触发  播放动画事件play.RegisterOnButtonPressed(PlayAnimation);//添加移动按钮按下时 触发  零件拆解事件move.RegisterOnButtonPressed(SplitItem);//捕捉到图片时    出现模型machineObserverEvent.OnTargetFound.AddListener(IsFound);//图片消失时      隐藏模型machineObserverEvent.OnTargetLost.AddListener(IsLost);}private void PlayAnimation(VirtualButtonBehaviour play){isPress = !isPress;if (isPress){print("开始动画按钮被点击");machineAnimator.SetBool("isPlay", true);}else{print("结束动画按钮被点击");machineAnimator.SetBool("isPlay", false);}}private void SplitItem(VirtualButtonBehaviour split){isSplit = !isSplit;if (isSplit){//零件拆开//Split();print("拆解零件按钮被点击");machineAnimator.SetBool("isSplit", true);machineAnimator.SetBool("isMerge", false);}else{//零件合并//Merge();print("合并零件按钮被点击");machineAnimator.SetBool("isSplit", false);machineAnimator.SetBool("isMerge", true);}}public void IsFound(){machine.SetActive(true);print("出现");}public void IsLost(){machine.SetActive(false);print("消失");}
