（Unity）换装

zhezheil换装系统就是更换蒙皮、合兵蒙皮的过程。

蒙皮渲染器:

带蒙皮的网格渲染器 (Skinned Mesh Renderer) - Unity 手册

换装主要会用到其下的bones、mesh、material这三个数据，收集并合并到主蒙皮网格渲染器里。

核心内容在：收集数据合并数据里

for(int i = 0; i < partlist.Length; i++)
        {
            //骨骼
            for(int j = 0; j < SmrDic[partlist[i]].bones.Length; j++)
            {
                Transform t = SmrDic[partlist[i]].bones[j];
                bonesList.Add(t);
            }
            //材质
            mateList.Add(SmrDic[partlist[i]].sharedMaterial);
            //网格
            CombineInstance combine = new CombineInstance();
            combine.mesh = SmrDic[partlist[i]].sharedMesh;
            meshList.Add(combine);
        }
        //合并赋值
        PlayerSmr.bones = bonesList.ToArray();
        PlayerSmr.sharedMaterials = mateList.ToArray();
        Mesh mesh = new Mesh();
        mesh.CombineMeshes(meshList.ToArray(), false, false);
        PlayerSmr.sharedMesh = mesh;

 这里我用2D轮转图来作为切换部位的控件

            for(int j = 0; j < SmrDic[partlist[i]].bones.Length; j++)

        }
        //合并赋值
        PlayerSmr.bones = bonesList.ToArray();
        PlayerSmr.sharedMaterials = mateList.ToArray();
        Mesh mesh = new Mesh();
        mesh.CombineMeshes(meshList.ToArray(), false, false);
        PlayerSmr.sharedMesh = mesh;
    }
    void Update()
    {
        
    }
}
