    My Mic "self.global" issues.

    edited October 2013 in Game & application design
    I've been getting some help behind the scenes from @ar2rsawseen but I don't want to worry him. I'm so close to finishing up my app (yes almost 2yrs and going) . I'm adding a microphone option to my options page and I'm confused about local and self. @ar2rsawseen told me to change from stage to self which I have done but when I hit the screen, I briefly see the images and microphone options but then it disappears. Later I'm able to click the buttons and record like normal however I guess I don't completely understand why it comes in then disppears.

    Any clue? Here is some of my options code:
     
require "microphone"
 
Options = gideros.class(Sprite)
 
-- options
 
local width = application:getContentWidth()
local height = application:getContentHeight()
 
local dx = application:getLogicalTranslateX() / application:getLogicalScaleX()
local dy = application:getLogicalTranslateY() / application:getLogicalScaleY()
 
function Options:init()
 
self.levelMeter = LevelMeter.new()
self:addChild(self.levelMeter)
self.levelMeter:setY(30)
 
 
self.microphone = Microphone.new(nil, 22050, 1, 16)
 
self.microphone:addEventListener(Event.DATA_AVAILABLE, function(event)
	print("*")
	self.levelMeter:setLevel(event.peakAmplitude, self)
end)
 
self.microphone:setOutputFile("|D|record.wav")
 
self.record = Button.new(	Bitmap.new(Texture.new("gfx/record-up.png")),
							Bitmap.new(Texture.new("gfx/record-down.png")),
							Bitmap.new(Texture.new("gfx/record-disabled.png")))
self.record:setPosition(70, 130)
self:addChild(self.record)
 
 
self.recordStop = Button.new(	Bitmap.new(Texture.new("gfx/stop-up.png")),
								Bitmap.new(Texture.new("gfx/stop-down.png")))
self.recordStop:setPosition(70, 130)
 
 
self.play = Button.new(	Bitmap.new(Texture.new("gfx/play-up.png")),
							Bitmap.new(Texture.new("gfx/play-down.png")),
							Bitmap.new(Texture.new("gfx/play-disabled.png")))
self.play:setPosition(70, 200)
self.play:setDisabled(true)
self:addChild(self.play)
 
 
self.playStop = Button.new(Bitmap.new(Texture.new("gfx/stop-up.png")),
							Bitmap.new(Texture.new("gfx/stop-down.png")))
self.playStop:setPosition(70, 200)
 
 
function self:onRecord()
	self.play:setDisabled(true)
	self.record:removeFromParent()
	self:addChild(self.recordStop)
	self.microphone:start()
end
 
self.record:addEventListener(Event.CLICK, self.onRecord, self)
 
function self:onRecordStop()
	self.play:setDisabled(false)
	self.recordStop:removeFromParent()
	self:addChild(self.record)
	self.microphone:stop()
	self.levelMeter:setLevel(0)
	self.play:setDisabled(false)
end
self.recordStop:addEventListener(Event.CLICK, self.onRecordStop, self)
 
 
local sound = nil
local channel = nil
 
function self:onPlayStop()
	self.record:setDisabled(false)
	self.playStop:removeFromParent()
	self:addChild(self.play)
	self.channel:stop()
end
self.playStop:addEventListener(Event.CLICK, self.onPlayStop, self)
 
function self:onPlay()
	self.record:setDisabled(true)
	self.play:removeFromParent()
	self:addChild(self.playStop)
	self.sound = Sound.new("|D|record.wav")
	self.channel = self.sound:play()
	self.channel:addEventListener(Event.COMPLETE, self.onPlayStop, self)
end
self.play:addEventListener(Event.CLICK, self.onPlay, self)
 
 
self.background = Bitmap.new(TextureRegion.new(Texture.new("gfx/mainlandscape.png", true)))	
self:addChild(self.background)
 
--set position in center 
 
self.background:setAnchorPoint(0.5, 0.5)
self.background:setPosition(width/2, height/2)
 
local texture = Texture.new("gfx/home.png")
 
local back = Bitmap.new(texture)
back:setScale(1)
self.back = Button.new(back, back)
self.back:setPosition((width-self.back:getWidth())/2, 40)
self:addChild(self.back)
self.back:addEventListener("click", function()
	sc.scenes:changeScene("StartPage",1, SceneManager.fade, moveFromRightWithFade) 
end)
end
    Thanks for any explanation. I've looked other sample code and some include self and local. I'm quite confused about the two and when to use.

      @Ar2rsawseen,
      Ha, ha! ;))

      Still, would you mind posting a brief summary of the solution here for all to see?

      Honestly, I dont know the problem
      I just took the project of @mysps I had previously, and added the code from mic example project.

      Did not post here, because it is a private @mysps project, so send through pm and let @mysps figure out what was wrong :)

      @mysps, did you figure out what made the items disappear?

      @Platypus, so I studied the changes that @ar2rsawseen sent and understood it a bit.

      Questions:

      Why isn't the function Microphone not added to self?
      local microphone = Microphone.new(nil, 22050, 1, 16)
 
	microphone:addEventListener(Event.DATA_AVAILABLE, function(event)
		print("*")
		levelMeter:setLevel(event.peakAmplitude)
	end)
 
	microphone:setOutputFile("|D|record.wav")
      When I made different changes, I believe I had it like this but I added self to the microphone which caused an error saying that the .wav wasn't found.

      Thanks again Arturs and Happy Birthday!!

      Here is the correct code:
      Options = gideros.class(Sprite)
 
require "microphone"
-- options
 
local width = application:getContentWidth()
local height = application:getContentHeight()
 
local dx = application:getLogicalTranslateX() / application:getLogicalScaleX()
local dy = application:getLogicalTranslateY() / application:getLogicalScaleY()
 
function Options:init()
 
	self.background = Bitmap.new(TextureRegion.new(Texture.new("gfx/mainlandscape.png", true)))	
	self:addChild(self.background)
 
	--set position in center 
 
	self.background:setAnchorPoint(0.5, 0.5)
	self.background:setPosition(width/2, height/2)
 
	local texture = Texture.new("gfx/home.png")
 
	local back = Bitmap.new(texture)
	back:setScale(1)
	self.back = Button.new(back, back)
	self.back:setPosition((width-self.back:getWidth())/2, 20)
	self:addChild(self.back)
	self.back:addEventListener("click", function()
		sc.scenes:changeScene("StartPage",1, SceneManager.fade, moveFromRightWithFade) 
	end)
 
	local levelMeter = LevelMeter.new()
	self:addChild(levelMeter)
	levelMeter:setPosition((width-levelMeter:getWidth())/2, 200)
 
	local microphone = Microphone.new(nil, 22050, 1, 16)
 
	microphone:addEventListener(Event.DATA_AVAILABLE, function(event)
		print("*")
		levelMeter:setLevel(event.peakAmplitude)
	end)
 
	microphone:setOutputFile("|D|record.wav")
 
	local record = Button.new(	Bitmap.new(Texture.new("gfx/record-up.png")),
							Bitmap.new(Texture.new("gfx/record-down.png")),
							Bitmap.new(Texture.new("gfx/record-disabled.png")))
	record:setPosition((width - record:getWidth())/2, 260)
	self:addChild(record)
 
 
	local recordStop = Button.new(	Bitmap.new(Texture.new("gfx/stop-up.png")),
								Bitmap.new(Texture.new("gfx/stop-down.png")))
	recordStop:setPosition((width - recordStop:getWidth())/2, 260)
 
 
	local play = Button.new(	Bitmap.new(Texture.new("gfx/play-up.png")),
							Bitmap.new(Texture.new("gfx/play-down.png")),
							Bitmap.new(Texture.new("gfx/play-disabled.png")))
	play:setPosition((width - play:getWidth())/2, 360)
	play:setDisabled(true)
	self:addChild(play)
 
 
	local playStop = Button.new(Bitmap.new(Texture.new("gfx/stop-up.png")),
							Bitmap.new(Texture.new("gfx/stop-down.png")))
	playStop:setPosition((width - playStop:getWidth())/2, 360)
 
 
	local function onRecord()
		play:setDisabled(true)
		record:removeFromParent()
		self:addChild(recordStop)
		microphone:start()
	end
	record:addEventListener(Event.CLICK, onRecord)
 
	local function onRecordStop()
		play:setDisabled(false)
		recordStop:removeFromParent()
		self:addChild(record)
		microphone:stop()
		levelMeter:setLevel(0)
		play:setDisabled(false)
	end
	recordStop:addEventListener(Event.CLICK, onRecordStop)
 
 
	local sound = nil
	local channel = nil
 
	local function onPlayStop()
		record:setDisabled(false)
		playStop:removeFromParent()
		self:addChild(play)
		channel:stop()
	end
	playStop:addEventListener(Event.CLICK, onPlayStop)
 
	local function onPlay()
		record:setDisabled(true)
		play:removeFromParent()
		self:addChild(playStop)
		sound = Sound.new("|D|record.wav")
		channel = sound:play()
		channel:addEventListener(Event.COMPLETE, onPlayStop)
	end
	play:addEventListener(Event.CLICK, onPlay)
end
