+### hideFloorImg：隐藏贴图
+
+使用`{"type":"hideFloorImg"}`可以隐藏某个楼层的贴图。
+
+有关贴图说明请参见[使用自己的图片作为某层楼的背景/前景素材](personalization#使用自己的图片作为某层楼的背景前景素材)。
+
+``` js
+"x,y": [ // 实际执行的事件列表
+  {"type": "hideFloorImg", "loc": [3,6], "floorId": "MT1"}, // 隐藏[3,6]的贴图
+  {"type": "hideFloorImg", "loc": [3,6]}, // 如果是当前层，则可以省略floorId项
+  {"type": "hideFloorImg", "loc": [[3,6],[2,9],[1,2]]} // 我们也可以同时隐藏多个贴图。
+]
+```
+
+loc为要隐藏的贴图的左上角坐标，可以简单的写[x,y]代表一个点，也可以写个二维数组[[x1,y1],[x2,y2],...]来同时显示多个点。
+
+如果同时存在若干个贴图都是是该坐标为左上角，则这些贴图全部会被隐藏。
+
+floorId为目标点的楼层，如果是当前楼层可以忽略不写。
+
+### showFloorImg：显示贴图
+
+使用`{"type":"showFloorImg"}`可以显示某个楼层的贴图。
+
+其做法和参数，和隐藏贴图是完全一致的。
+
+``` js
+"x,y": [ // 实际执行的事件列表
+  {"type": "showFloorImg", "loc": [3,6], "floorId": "MT1"}, // 显示[3,6]的贴图
+]
+```
+
 ### setBlock：设置某个图块
 
 我们可以采用 `{"type": "setBlock"}` 来改变某个地图块。
