+### screenFlash：画面闪烁
+
+我们可以使用 `{"type": "screenFlash"}` 来进行画面闪烁。
+
+``` js
+"x,y": [ // 实际执行的事件列表
+    {"type": "screenFlash", "color": [255,255,255,0.6], "time": 500, "times": 1}, // 闪光为白色，不透明度0.6，动画时间1000毫秒

+]
+```
+
+color为闪光的颜色。它是一个数组，分别指定目标颜色的R,G,B,A值。
+- 常见RGB颜色： 纯黑[0,0,0]，纯白[255,255,255]，纯红[255,0,0]，等等。
+A即闪光的不透明度，为一个0到1之间的数，值越高闪烁效果越强。默认为1
+
+time为闪烁时间，默认值为500
+
+times为闪烁次数，两次闪烁会连续进行，默认值为1
+
+async可选，如果为true则会异步执行（即不等待当前事件执行完毕，立刻执行下一个事件）。
+
 ### setWeather：更改天气
 
 我们可以使用 `{"type": "setWeather"}` 来更改天气。
