The project file is here

• https://kwiksher.com/tutorials/Kwik4/Storyboard.zip

The demo project consists of the two psd files and one storyboard that has been exported with Storyboard Editor

• page1.psd

• viewer.psd

  

• assets/storyboards/spring02

  

each page uses the external code files.

• 001-page01

  • ext/storyboard_show.lua
  • ext/storyboard_play.lua
  • ext/storyboard_hide.lua

• 002-viewer

  • ext/storyboard_init.lua
  • ext/storyboard_setup.lua
  • ext/storyboard_button_back.lua
  • ext/storyboard_dispose.lua

ext/lib must be copied to build4/lib manually

• img/
• storyboard.lua
• storyboardController.lua
• storyboardView.lua

page1

there is a button to load the viewer that has the external code. The event handler for the button event is configured with another external code for the page

button

• external code

  • storyboard_play.lua

  

External code for the page

code_dispose

• storyboard_hide.lua

• Disposal

  

code_storyboard

• storyboard_show.lua

• After buttons and actions

  

Codes

• storyboard_play.lua

  Runtime:dispatchEvent({name="showStoryboard", storyboard="spring02"})
  

• storyboard_hide.lua

  Runtime:removeEventListener("showStoryboard", _K.showStoryboard)
  

• storyboard_show.lua

  the second line sets the storyboard directory and the filename. You need to copy it to build4\assets folder manually

local storyboards = {}
storyboards["spring02"] = {dir="assets/storyboards/spring02", file="spring02.storyboarder"}
--
_K.showStoryboard = function(event)
    local composer = require("composer")
    composer.hideOverlay() -- if there has been another overlay opened
    --
    if _K.storyboardState == "pause" then
    _K.storyboardState = nil
    else
    _K.storyboardIndex = 1
    end
    --
    sceneGroup.alpha = 0.01
    --
    _K.storyboardDir = storyboards[event.storyboard].dir
    _K.storyboardFile = storyboards[event.storyboard].file
    _K.curPage        = UI.curPage
    --
    composer.showOverlay("views.page02Scene") -- viewer
    --
end

Runtime:addEventListener("showStoryboard", _K.showStoryboard)

  the controller box of play, stop, pause and slider is placed width layer.viewer.contentBounds.yMax.

  local storyboard = require("lib.storyboard")
  
  storyboard:init(sceneGroup, display.contentCenterX, layer.viewer.contentBounds.yMax, display.actualContentWidth, display.viewableContentHeight-layer.viewer.contentBounds.yMax)

  storyboard:dialoguePos(layer.dialogue.x, layer.dialogue.y, layer.dialogue.width, layer.dialogue.height)
  -- 
  -- The storyboard:init function creates the display objects for the controller at the runtime. 
  -- The positions of the following image objects are referenced and the image objects are just reference
  -- so they should be invisible.
  layer.character.alpha = 0
  layer.comment.alpha = 0
  layer.dialogue.alpha = 0
  layer.slider.alpha = 0
  layer.timeTxt.alpha = 0
  layer.controls.alpha = 0
  

• storyboard_setup.lua

  when the page is loaded, the viewer starts to play with storyboard.controls:render(_K.storyboardIndex)

  local storyboard = require("lib.storyboard")
  local composer = require("composer")
  
  storyboard.controls:init(layer.viewer)
  storyboard.controls:setStoryboarder(_K.storyboardDir, _K.storyboardFile, _K.systemDir)
  storyboard.controls:decodeJson()
  
  storyboard.controls:render(_K.storyboardIndex)
  Runtime:addEventListener("enterFrame", storyboard.controls)
  
  -- tap to toggle show/hide the controller buttons
  storyboard.controls.image:addEventListener("tap", function()
      if storyboard.controls.group.alpha == 0 then
          storyboard.controls:showTextField()
          storyboard.controls.group.alpha = 1
          storyboard.view.timeTxt.alpha = 1
      else 
          storyboard.controls:hideTextField()
          storyboard.controls.group.alpha = 0
          storyboard.view.timeTxt.alpha = 0
      end
      return false
  end)
  

• storyboard_dispose.lua

  local storyboard = require("lib.storyboard")
  storyboard.controls:dispose()
  

That's all.
