there are 2 problems.

  1. num should be declared outside timer function
  2. newtext function should have 5 arguments
    (text,left,right,font,size)

see the sample
[lua]local t = display.newText(“0”, 115, 105, nil, 25 )
t:setTextColor( 255, 255, 255 )

local num = 0
function t:timer( event )
count = event.count
self.text = count
if count >= 20 then
timer.cancel( event.source )
num=count
end
end

timer.performWithDelay( 500, t, 50 )

local ti = display.newText( num, 100, 100, nil,25 )
ti:setTextColor( 255, 255, 255 )[/lua]

when i try this code the strings overlaps. I dint understand what you are trying to achieve with this. [import]uid: 71210 topic_id: 17054 reply_id: 64039[/import]
