【Unity开发】Unity实现glb模型上传到场景中使用功能

一、效果展示

点击按钮上传glb格式的模型，进行后续移动、旋转和缩放操作，上传的模型会出现在原点（0,0,0）位置
演示视频：

二、环境要求

需要下载安装用于加载glb模型的插件，下载好后直接拖入项目中进行使用

三、实现完整代码

using System.Collections;
using UnityEngine.UI;

using System.Windows.Forms;
using Button = UnityEngine.UI.Button;

using UnityEditor;
#endif

{public Transform modelParent; // 模型的父节点public Button uploadButton;   // UI按钮，点击触发上传void Start(){uploadButton.onClick.AddListener(OnUploadButtonClicked);}void OnUploadButtonClicked(){//在unity编辑器中进行模型上传
#if UNITY_EDITORstring path = EditorUtility.OpenFilePanel("选择模型", "", "glb,gltf");if (!string.IsNullOrEmpty(path)){StartCoroutine(LoadModel(path));}//导出exe后进行模型上传
#elif UNITY_STANDALONE_WINstring path = OpenFileDialogWin("选择模型文件", "glb|*.glb|gltf|*.gltf");if (!string.IsNullOrEmpty(path)){StartCoroutine(LoadModel(path));}
