Corona SDK - Neon Effect in Text or Shape - First Way

main.lua

--a not effective way to make a neon text in corona sdk, the trick is make a loop and down the alpha
--you can use it to make shapes in neon too ;)
--email me: [email protected] ;)

---Circle Example
--i = 0
--while i < neonSize do
--    t = display.newCircle(x,y,circleSize + i) --create the circle
--    t:setFillColor(colorR,colorG,colorB) --set the color of the text
--    t.alpha = 1/i * 1 --change alpha
--    i = i + 1 --continue the loop
--end
---

display.setStatusBar(display.HiddenStatusBar) --hide status bar

--define values
background = display.newImage("background.png",0,0) --create background image
string  = "corona" --define the text
x = 100 --the text x
y = 100 --the text y
textFont = "Helvetica"
fontSize = 60 --the font size
colorR = 0 --the R value of the text
colorG = 255 --the G value of the text
colorB = 255 --the B value of the text
neonSize = 5 --change the neon range

--make the loop
i = 0
while i < neonSize do
    t = display.newText(string,x + i,y - i,textFont,fontSize) --create text
    t:setTextColor(colorR,colorG,colorB) --set the color of the text
    t.alpha = 1/i * 1 --change alpha
    i = i + 1 --continue the loop
end
