+### setValue2：增减勇士的某个属性、道具个数，或某个变量/Flag的值
+
+和`{"type": "setValue"}`的写法完全相同，不过此项是可以直接将值加减到原始数值上。
+
+即下面的写法是等价的：
+
+``` js
+"x,y": [ // 实际执行的事件列表
+    {"type": "setValue", "name": "status:atk", "value": "status:atk+10" } // 攻击提高10点
+    {"type": "setValue2", "name": "status:atk", "value": "10" } // 和上面写法等价
+    {"type": "setValue", "name": "item:yellowKey", "value": "item:yellowKey-3" } // 黄钥匙个数-3
+    {"type": "setValue2", "name": "item:yellowKey", "value": "-3" } // 和上面写法等价
+    {"type": "setValue", "name": "flag:door2", "value": "flag:door2+1" } // 将变量door值+1
+    {"type": "setValue2", "name": "flag:door2", "value": "01" } // 和上面写法等价

 ### setFloor：设置楼层属性
 
 使用`{"type":"setFloor"}`可以设置某层楼的楼层属性。
