提取Unity中的fbx文件中的動畫片段您觉。

整體思路是：

將fbx加載后，獲取AnimationClip信息拖吼，然后序列滑到新文件中鳞上。

// 生成新的AnimationClip

? ? ? ? ? ? ? ? ? ? ? ? AnimationClip newClip = new AnimationClip();

? ? ? ? ? ? ? ? ? ? ? ? newClip.frameRate = 25;

? ? ? ? ? ? ? ? ? ? ? ? newClip.name = objs[j].name;

? ? ? ? ? ? ? ? ? ? ? ? // 復制數(shù)據(jù)

? ? ? ? ? ? ? ? ? ? ? ? // 方法1：該方法僅設置有效數(shù)據(jù)，編輯器相關數(shù)據(jù)不會設置到導出資源中

? ? ? ? ? ? ? ? ? ? ? ? EditorUtility.CopySerialized(objs[j], newClip);

直接上代碼：

public class AnimationExporter : AssetBaseExporter { public class FbxInfo { public string m_AssetPath; public string m_AssetName; // 資源名 public bool m_IsExport; // 是否導出 public bool m_IsCompress; //是否壓縮 } string m_AssetPathPrefix = "Assets/Resources/Models";
