Components

For instance components/pageX/page/swip.lua enables a page transition, and components/pageX/audios folder can have multiple audio lua files for instance short/audioOne.lua, long/audioTwo.lua. short audio file is loaded in to memory with audio.loadSound(), and long audio file is streaming with audio.loadStream().

local sceneName = ...
--
local scene = require('controller.scene').new(sceneName, {
    name = "pageX",
    components = {
      layers = {
          {  bg={} },
      },
      audios = { short = {"audioOne"}, long= {"audioTwo" },
      groups = {  },
      timers = {  },
      variables = {  },
      page = { "controllers.swipe" }
     },
    commands = { },
    onInit = function(scene) print("onInit") end
})

return scene

Common components

You can add a common component to components/common directory

And let it pass in arguments of bootstrap function in main.lua

local common = {commands = {"myEvent"}, components = {"myComponent"}}

require("controller.index").bootstrap({
  name="book", sceneIndex = 1, position = {x=0, y=0},
  common =common
})

Common components are executed after all the layer components of a scene are rendered. So you can access a layer component by UI.layers table.

for instance, myComponent.lua attaches a tap listener


function _M:didShow(UI)
  local sceneGroup = UI.scene.view

  UI.layers.bg:addEventListener("tap", function(event)
      print("bg is tapped")
  end)

end
