AR本地加載資源

1，首先把之前的腳本複制一份，重新編寫此腳本

2，,這裡寫代碼片

//找到  
    private void OnTrackingFound()
    {
        GameObject aixi = Instantiate(aixiPrefab,transform.position-new Vector3(0,-1.6f,0),transform.rotation);          
        aixi.transform.parent = this.transform;

        GameObject e1 = Instantiate(bloodPrefab1, transform.position, Quaternion.identity);
        e1.transform.parent = this.transform;
        Destroy(e1, 5f);
        GameObject e2 = Instantiate(bloodPrefab2, transform.position, Quaternion.identity);
        e2.transform.parent = this.transform;
        Destroy(e2, 5f);

    }
    //丢失識别圖
    private void OnTrackingLost()
    {
        Destroy(GameObject.Find("aixi(Clone)"));
        Destroy(GameObject.Find("e1(Clone)"));
        Destroy(GameObject.Find("e2(Clone)"));

    }
           

3，制作陰影，添加一個renderTexture - 賦給相機- 添加一個3DPlane-把renderTexture- 賦給3DPlane-把相機改為SolidColor

4，改變物體的Layer層-使相機隻照射到aixi層
