EventDispatcher.lua

使用方式

---

--- 单例模式

local EventDispatcher = require("EventDispatcher"):getInstance()

--- 定义函数eventA，函数返回true会停止后续监听器的执行

local function eventA(param1, param2, ...)
  print("function eventA")
  return true
end

--- 添加事件EVENT_A监听。第三个参数为优先级，255,-255之间

EventDispatcher:addListener("EVENT_A", eventA)
or
EventDispatcher:addListener("EVENT_A", eventA, 15)

--- 执行事件EVENT_A，并传递参数param1, param2, ...

EventDispatcher:dispatch("EVENT_A", param1, param2, ...)
