Text Candy and director change scene problem

Antheor · April 2, 2011, 2:17pm

When I try to change scene, from a copy paste code based on vector font, I get the following issue :
"
–> TEXT FX SYSTEM READY.
–> TextFX.AddVectorFont(): ADDED VECTOR FONT ‘Floraless’
–> TextFX.CreateText(): TEXT CREATED.
WARNING: Attempt to set object.alpha to 1.015 which is outside valid range. It will be clamped to the range [0,1]
–> TextFX.RemoveCharset(): REMOVING CHARSET ‘Floraless’…
–> TextFX.DeleteText(): TEXT DELETED. REMAINING TEXTS: 0
Runtime error
…rd/programmation/Corona/sandboxes/lib_text_candy.lua:288: attempt to index field ‘Sheet’ (a nil value)
stack traceback:

"

And this is my code :
 module(..., package.seeall) --------------------------------------------------------------- -- GROUPS --------------------------------------------------------------- local localGroup = display.newGroup() --------------------------------------------------------------- -- VARIABLES --------------------------------------------------------------- local w, h = display.contentWidth, display.contentHeight --------------------------------------------------------------- -- DISPLAY OBJECTS --------------------------------------------------------------- local title = display.newText("HOME", 0, 0, native.systemFontBold, 16) ------------------------------ -- TEXT CANDY ------------------------------ -- LOAD & ADD A CHARSET TextCandy.AddVectorFont ("Floraless", "0123456789AÄBCDEFGHIJKLMNOÖPQRSTUÜVWXYZ'*@():,$.!-%+?;#/_", 32) -- CREATE A TEXT OBJECT USING THIS CHARSET local MyText = TextCandy.CreateText({ fontName = "Floraless", x = w*.5, y = h*.5, text = "THIS IS A CUSTOM TRUE TYPE FONT.", originX = "CENTER", originY = "CENTER", textFlow = "CENTER", charSpacing = 0, lineSpacing = -4, wrapWidth = 400, showOrigin = true, -- ADDITIONAL PROPERTIES YOU CAN USE WHEN CREATING VECTOR TEXTS: Color = {175,175,175, 255}, fontSize = 32, shadowOffX = 8, shadowOffY = 8, shadowAlpha = 128 }) --------------------------------------------------------------- -- FUNCTIONS and LISTENERS --------------------------------------------------------------- local function touched ( event ) if event.phase == "ended" then TextCandy.CleanUp() -- CLEAN UP *BEFORE* SWITCHING SCENES! director:changeScene("home","fade", "black") print("changeScene") end end --------------------------------------------------------------- -- INIT VARS --------------------------------------------------------------- local function initVars () ----------------------------------- -- Inserts ----------------------------------- localGroup:insert(title) localGroup:insert(MyText) ----------------------------------- -- Positions ----------------------------------- title.x = 160 title.y = 20 ----------------------------------- -- Colors ----------------------------------- title:setTextColor( 130,130,130) ----------------------------------- -- Listeners ----------------------------------- title:addEventListener( "touch" , touched ) end --------------------------------------------------------------- -- CLEAN --------------------------------------------------------------- function clean ( event ) -- DO NOT CLEAN UP HERE -- btw, do you make the same advice for Particle Candy ? print("cleaned") end --------------------------------------------------------------- -- NEW --------------------------------------------------------------- function new() ----------------------------------- -- Initiate variables ----------------------------------- initVars() ----------------------------------- -- MUST return a display.newGroup() ----------------------------------- return localGroup end

I may be wrong, but I don’t think you need to call TextCandy.CleanUp() on a Vector Font as there is no associated bitmap to clean up [import]uid: 8366 topic_id: 8523 reply_id: 30573[/import]

Removing the cleanup indeed solved the error …Thx for the hint -though there’s no info about vector no need to clean up in reference page-

Maybe I should open an new topic :

I start to test deform and animation, and it’s - the xpressive way - simple, effective, fun and wowfactor. Really cool !

One question : animation are made to “animate these properties smoothly back and forth” (from the reference page): what if I don’t want to have back and forth (having a continuous rotation for instance) ?
