Vuforia AR篇（三）— AR模型出场效果

前言

例如：随着人工智能的不断发展，机器学习这门技术也越来越重要，很多人都开启了学习机器学习，本文就介绍了机器学习的基础内容。

一、AR模型出场

创建ARCamera和ImageTarget

导入一个带动画的模型

复制下面的脚本

然后改名成下面DeathObserverEventHandler

找到下面的2个方法

重写下面的2个方法

    protected virtual void OnTrackingFound()
    {
        // if (mObserverBehaviour)
        //     SetComponentsEnabled(true);
        //
        //
        //
        // OnTargetFound?.Invoke();
        GameObject death = Instantiate(deathPrefab, transform, true);
        death.name = "Death";
        death.transform.position = transform.position;
    }

    protected virtual void OnTrackingLost()
    {
        // if (mObserverBehaviour)
        //     SetComponentsEnabled(false);
        //
        //
        // OnTargetLost?.Invoke();
        GameObject death = GameObject.Find("Death");
        if (death != null)
        {
            Destroy(death);
        }

    }

然后挂上脚本

二、AR出场特效

导入特效素材


添加特效代码

    protected virtual void OnTrackingFound()
    {
        // if (mObserverBehaviour)
        //     SetComponentsEnabled(true);
        //
        //
        //
        // OnTargetFound?.Invoke();
        GameObject death = Instantiate(deathPrefab, transform, true);
        death.name = "Death";
        death.transform.position = transform.position;
        GameObject effect = Instantiate(effectPrefab, transform, true);
        effect.name = "Effect";
        effect.transform.position = transform.position;
    }

    protected virtual void OnTrackingLost()
    {
        // if (mObserverBehaviour)
        //     SetComponentsEnabled(false);
        //
        //
        // OnTargetLost?.Invoke();
        GameObject death = GameObject.Find("Death");
        if (death != null)
        {
            Destroy(death);
        }

        GameObject effect = GameObject.Find("Effect");
        if (effect != null)
        {
            Destroy(effect);
        }
    }

三、添加过渡效果

    private void Update()
    {
        _death.transform.localPosition = Vector3.Lerp(_death.transform.localPosition , Vector3.zero, Time.deltaTime);
        _death.transform.localScale = Vector3.Lerp(_death.transform.localScale , new Vector3(0.4f, 0.4f, 0.4f), Time.deltaTime);
    }

    protected virtual void OnTrackingFound()
    {
        // if (mObserverBehaviour)
        //     SetComponentsEnabled(true);
        //
        //
        //
        // OnTargetFound?.Invoke();
         _death = Instantiate(deathPrefab, transform, true);
        _death.name = "Death";
        
        
        GameObject effect = Instantiate(effectPrefab, transform, true);
        effect.name = "Effect";
        effect.transform.position = transform.position;
    }


    protected virtual void OnTrackingLost()
    {
        // if (mObserverBehaviour)
        //     SetComponentsEnabled(false);
        //
        //
        // OnTargetLost?.Invoke();
        GameObject death = GameObject.Find("Death");
        if (death != null)
        {
            Destroy(death);
        }

        GameObject effect = GameObject.Find("Effect");
        if (effect != null)
        {
            Destroy(effect);
        }
    }
