需求：

找到了黄马褂的结构：

我们新建一个DragonBones项目 ， 用以为上述黄马褂换肤

我们对DragonE_view进行修改

重点 ：

            this.egretFactory.parseDragonBonesData(RES.getRes("DragonChange_ske_json"));
            this.egretFactory.parseTextureAtlasData(RES.getRes("DragonChange_tex_json"), RES.getRes("DragonChange_tex_png"));
            this.egretFactory.replaceSlotDisplay( "DragonChange", "Armature", "clothes2", "clothes2", this.eff_robot.armature.getSlot("clothes"));

replaceSlotDisplay ： 替换一个骨头的显示

第一个参数 ： 替换项目的名称

第二个参数 ： 替换目场景名字

第三个参数 ： 替换项目的骨骼名字

第五个参数 ： 替换项目的图片名字

第五个参数 ： 被替换项目的卡槽

结果 ：

全局换装 ：：：//将图集全部替换

ar.armature.replaceTexture(RES.getRes("new_db_texture_png"));
