Unity運(yùn)行時(shí)程序動(dòng)態(tài)加載外部.fbx.obj模型文件

項(xiàng)目中有用到這個(gè)需求，為實(shí)現(xiàn)Unity程序運(yùn)行狀態(tài)下，從程序外部動(dòng)態(tài)加載fbx或obj模型,所以研究了一下，目前TriLib比較靠譜，好用，多平臺(tái)適用。會(huì)提供 下載插件地址。

1.效果展示

使用的插件 下載插件地址

2、添加插件至Unity工程

將Trilib壓縮包內(nèi)容解壓到Unity工程Assets文件夾下，返回工程等待加載，完成后即可在工程目錄下看到Trilib目錄，包含腳本以及各類License。Trilib插件包含了示例場(chǎng)景，我們的工程就從示例入手。

先擇模型，看效果。

3、使用步驟

代碼調(diào)用示例

        /// <summary>
        /// Loads the "Models/TriLibSample.obj" Model using the given AssetLoaderOptions.
        /// </summary>
        /// <remarks>
        /// You can create the AssetLoaderOptions by right clicking on the Assets Explorer and selecting "TriLib->Create->AssetLoaderOptions->Pre-Built AssetLoaderOptions".
        /// </remarks>
        private void Start()
        {
            var assetLoaderOptions = AssetLoader.CreateDefaultLoaderOptions();
            AssetLoader.LoadModelFromFile(ModelPath, OnLoad, OnMaterialsLoad, OnProgress, OnError, null, assetLoaderOptions);
        }

        /// <summary>
        /// Called when any error occurs.
        /// </summary>
        /// <param name="obj">The contextualized error, containing the original exception and the context passed to the method where the error was thrown.</param>
        private void OnError(IContextualizedError obj)
        {
            Debug.LogError($"An error occurred while loading your Model: {obj.GetInnerException()}");
        }

        /// <summary>
        /// Called when the Model loading progress changes.
        /// </summary>
        /// <param name="assetLoaderContext">The context used to load the Model.</param>
        /// <param name="progress">The loading progress.</param>
        private void OnProgress(AssetLoaderContext assetLoaderContext, float progress)
        {
            Debug.Log($"Loading Model. Progress: {progress:P}");
        }

        /// <summary>
        /// Called when the Model (including Textures and Materials) has been fully loaded.
        /// </summary>
        /// <remarks>The loaded GameObject is available on the assetLoaderContext.RootGameObject field.</remarks>
        /// <param name="assetLoaderContext">The context used to load the Model.</param>
        private void OnMaterialsLoad(AssetLoaderContext assetLoaderContext)
        {
            Debug.Log("Materials loaded. Model fully loaded.");
        }

        /// <summary>
        /// Called when the Model Meshes and hierarchy are loaded.
        /// </summary>
        /// <remarks>The loaded GameObject is available on the assetLoaderContext.RootGameObject field.</remarks>
        /// <param name="assetLoaderContext">The context used to load the Model.</param>
        private void OnLoad(AssetLoaderContext assetLoaderContext)
        {
            Debug.Log("Model loaded. Loading materials.");
        }

總結(jié)

以上就是使用trilib2.1.7 動(dòng)態(tài)加載fbx模型。有問題請(qǐng)留言。文章來源地址http://www.zghlxwxcb.cn/news/detail-564213.html
