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

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 update
    void 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 frame
	void 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 update
    void 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 frame
	void 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.

    void 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
