Here’s what the Simulator output shows:

-- show() function scene:show( event ) local sceneGroup = self.view local phase = event.phase if ( phase == "will" ) then -- Code here runs when the scene is still off screen (but is about to come on screen) elseif ( phase == "did" ) then -- Code here runs when the scene is entirely on screen transition.fadeIn(bg, { time = 5000 }) Dialogue.TextBlock({ [1] = "This is the story of the last Samurai.", [2] = "Stuff" }, 500, 300, 2500, 72, 1, 1, 1) end end

And from a Dialogue.lua:

function TextFader(MSG, X, Y, SPEED, SIZE, R, B, G) local textblock = display.newText( MSG, X, Y, native.systemFont, SIZE ) textblock.alpha = 0 textblock:setFillColor( R, B, G ) transition.fadeIn(textblock, {time = SPEED}) local function afterTimer() transition.fadeOut(textblock, {time = SPEED}) end timer.performWithDelay(SPEED \* 2, afterTimer, 1) end function TextBlock(MSG, X, Y, SPEED, SIZE, R, B, G) --MSG should be an array print("Size:"..#MSG) for i = 1, #MSG do if (MSG[i] == nil) then print("i:"..i.." is nil.") else print("not nil:"..MSG[i]..":"..i) -- (SPEED + (SPEED \* 2) + SPEED) \* i timer.performWithDelay(100, TextBlock(MSG[i], X, Y+(SIZE\*i), SPEED, SIZE, R, B, G), 1) --Initial message must show then timer must stack so not everything appears at once in the array. end end end Dialogue.Textshake = Textshake Dialogue.TextFader = TextFader Dialogue.TextBlock = TextBlock

I just hacked your code so at least it works, but I have no idea what you are trying to do :smiley:

function TextBlock(MSG, X, Y, SPEED, SIZE, R, B, G) --MSG should be an array print("Size:"..#MSG) for i = 1, #MSG do if (MSG[i] == nil) then print("i:"..i.." is nil.") else print("not nil:"..MSG[i]..":"..i) local t = (SPEED + (SPEED \* 2) + SPEED) \* i --Initial message must show then timer must stack so not everything appears at once in the array. timer.performWithDelay(t, function() TextFader(MSG[i], X, Y+(SIZE\*i), SPEED, SIZE, R, B, G) end, 1) end end end Dialogue.Textshake = Textshake Dialogue.TextFader = TextFader Dialogue.TextBlock = TextBlock -- Code here runs when the scene is entirely on screen Dialogue.TextBlock({ [1] = "This is the story of the last Samurai.", [2] = "Stuff" }, 100, 200, 2500, 72, 0, 0, 0)

I assume you want to fade in and out the texts in your MSG array?

#3

Precisely, basically the array is a paragraph and I want to fade in text and have it fade out. So the effect would be a giant paragraph that fades in from the top and slowly fades out from the top. However it’s not working presumably cause of all the nils.

LOL you made me realize I just called TextBlock within it’s self. Thank you!
