using UnityEngine; using System.Collections; using UnityEditor;public class FBXAnimationsFix : AssetPostprocessor { public void OnPreprocessModel() { //當前正在導入的模型 ModelImporter modelImporter = (ModelImporter) assetImporter; AnimationClipConfig.init(); foreach (AnimationClipConfig.modelST item in AnimationClipConfig.modelList) { //當前導入模型的路徑包含我們modelST動作數據表中的模型名字，那就要對這個模型的動畫進行切割 if (assetPath.Contains(item.ModelName)) { modelImporter.animationType = ModelImporterAnimationType.Legacy; //modelImporter.splitAnimations = true; modelImporter.generateAnimations = ModelImporterGenerateAnimations.GenerateAnimations; ModelImporterClipAnimation[] animations = new ModelImporterClipAnimation[item.clipSTs.Length]; for (int i = 0; i < item.clipSTs.Length; i++) { animations[i] = SetClipAnimation(item.clipSTs[i].name, item.clipSTs[i].firstFrame, item.clipSTs[i].lastFrame, item.clipSTs[i].isloop); } modelImporter.clipAnimations = animations; } } }ModelImporterClipAnimation SetClipAnimation(string _name, int _first, int _last, bool _isLoop){ModelImporterClipAnimation tempClip = new ModelImporterClipAnimation();tempClip.name = _name;tempClip.firstFrame = _first;tempClip.lastFrame = _last;tempClip.loop = _isLoop;if (_isLoop)tempClip.wrapMode = WrapMode.Loop;elsetempClip.wrapMode = WrapMode.Default;return tempClip;} }
