Here you will find various resources to help you create texts in Gideros Studio.

note: you may have to provide your own assets (fonts, gfx, …)

Text Wrap @Gideros Wiki

-- TEXT WRAP FROM GIDEROS WIKI
local mystring = "Some very long text. Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed non risus. Suspendisse lectus tortor, dignissim sit amet, adipiscing nec, ultricies sed, dolor."
local textfield = TextField.new(nil, mystring)
textfield:setScale(2)
textfield:setSample(mystring)
textfield:setLayout( {w=144, h=100, lineSpacing=7, flags=FontBase.TLF_CENTER} )
textfield:setPosition(8, 16)
stage:addChild(textfield)

console = Core.class(Sprite)

function console:init()
	local fnt = TTFont.new("Assets/arial.ttf", 20)
	self.txt = TextField.new(fnt, nil)

	-- Simple scroll function
