unity人物换装

人物换装算是游戏中的老梗了，为了美化游戏，为获取更好的游戏体验，很多游戏中可以实现人物换装，还可以给人物更换武器，还要翅膀什么的。总之，能在玩家在体验上 带来很好的效果。
先看下效果图。

这个就把一个人物的形象稍微改变了下。为游戏增加些乐趣。

人物的皮肤的制作

首先看下人物皮肤的制作，其实这里美术已经给制作几套模型，我们之给第一套人物模型添加上骨骼，后面的就皮肤都不添加上骨骼了。只有给其加上SkinnedMeshRenderer，且只给添加上一套SkinnedMeshRenderer，不能够添加重复了。

这里就可以去批量生成衣服的prefab了。最好的CreatePrefabInternal（）函数就是一句自定义的制作prefab的函数了。

[MenuItem("GameObject/批量生成角色衣服Prefab", false, 0)]
    public static void GenerateBodyClothPrefab()
    
        if (index >= 1)
        
            ResetCreateNormalPrefabByFbxmane();
            return;
        
        index++;
        GameObject[] objs = Selection.gameObjects;
        for (int index1 = 0; index1 < objs.Length; index1++)
        
            GameObject obj = objs[index1];
            if (obj.GetComponent<SkinnedMeshRenderer>() == null)
            
                SkinnedMeshRenderer[] skins = obj.GetComponentsInChildren<SkinnedMeshRenderer>();
                if (skins != null && skins.Length > 0)
                
                    for (int i = 0; i < skins.Length; i++)
                    
                        CreateSingleBodySkinPrefab(skins[i].gameObject);
                    
                
            
            else
            
                CreateSingleBodySkinPrefab(obj);
            
        
    
 public static void CreateSingleBodySkinPrefab(GameObject skin)
    
        if (skin == null) return;
        SkinBonesRecord boneRecord = skin.GetComponent<SkinBonesRecord>();
        if (boneRecord == null)
            boneRecord = skin.AddComponent<SkinBonesRecord>();
        boneRecord.RecordBoneNames();
        SkinnedMeshRenderer mesh = skin.GetComponent<SkinnedMeshRenderer>();
        mesh.receiveShadows = false;
        mesh.useLightProbes = false;
        mesh.shadowCastingMode = UnityEngine.Rendering.ShadowCastingMode.Off;
        EditorUtility.SetDirty(skin);
        string prefabpath = tempPrefabFolderPath + skin.name + "skin.prefab";
        CreatePrefabInternal(skin, prefabpath);
    

加载衣服模型

衣服的prefab制作好了，我们在游戏中将其的assetBundle加载进来。这里是通过ShowClothStyle的id将其加载进来的，如果为0的话，就卸载当前的衣服，否则就进去穿衣服的函数。

 public void ShowEquipsFashionCloth(int ShowClothStyle)
        
            if (LoadConfigManager.ModelShowContainer.dic.ContainsKey(ShowClothStyle) == false)
            
#if UNITY_EDITOR
                Debug.LogFormat("不存在时装0", ShowClothStyle);
#endif
                return;
            
            #region 衣物模型生成
            if (ShowClothStyle != 0)
            
                //更换
                if (ShowClothStyle != _lastClothStyle && ShowClothStyle != 0)
                           characterGene.ChangeBodyCloth(ShowClothStyle, false);
                
            
            else
            
                //脱下装备
                if (_lastClothStyle != 0)
                
                    characterGene.RemoveBodyCloth();
                
            
            #endregion
            _lastClothStyle = ShowClothStyle;
        

下面的函数会先将旧的衣服的id号保存起来，然后装备里面的号码更新为新的id号。

public void ChangeBodyCloth(int modelid, bool isNgui = false, System.Action doneact = null)
     
        int oldclothid = 0;
        if (equipsModelCache.ContainsKey("body"))
            oldclothid = equipsModelCache["body"];
        var model = LoadConfigManager.ModelShowContainer.GetModelShow(modelid);
        if (model == null)
        
            return;
        
        equipsModelCache["body"] = modelid;
        GameManager.assetBundleNew.StartCoroutine(_ChangeBodyCloth(modelid, isNgui,oldclothid, doneact));
    

因为要在assetBundle里面加载，所有需要使用协程函数。

 private IEnumerator _ChangeBodyCloth(int clothid, bool isNgui, int oldClothid, System.Action doneact)
    
        if (characterRoot == null)
        
            Debug.Log("!!! character root is not exist");
            yield break;
        
        bool isMapRelevant = true;
        if (isNgui)
            isMapRelevant = true;
        GameObject newskinobj = GameManager.objectCacheMgr.SpawnByModelStyle(CacheType.ResName_Model, clothid, true);
        if (newskinobj == null)
        
            var abinfo = GameManager.assetBundleNew.CreateModelAB(clothid, false, true, isMapRelevant, isNgui);
            if (abinfo == null)
            
                yield break;
            
            while (!abinfo.IsDone)
                yield return null;

            newskinobj = abinfo.objInst as GameObject;
            if (isMapRelevant)
              //从缓存池里读取  AssetBundles.AssetBundleManagerNew.AddToMapRelDyUnloadAbInfos(abinfo, isMapRelevant);
            else
              //放入缓存里面  AssetBundles.ABLoadInfo.Release(abinfo);
            if (newskinobj == null)
            
                yield break;
            
        
        if (destroy)
               GameManager.objectCacheMgr.CacheExsistGOToCachePool(5, clothid, "", newskinobj, false, false);
            yield break;
        
        if (!equipsModelCache.ContainsKey("body") || equipsModelCache["body"] != clothid)
        
#if UNITY_EDITOR
            Debug.LogWarning(clothid + "---download clothid is not cur clothid---- " + "body --" + equipsModelCache["body"]);
#endif
            GameManager.objectCacheMgr.CacheExsistGOToCachePool(5, clothid, "", newskinobj, false, false);
            yield break;
        
        //共用一套总骨骼，但是需要更新信息，需要公用下载
        if (skins == null)
        
            Debug.LogError("no skin");
            yield break;
