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

2、为虚拟按钮设置名字

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

arp">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

arp">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

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.
