i have this code set off by a widget button named goBtn

it keeps displaying the new randomly generated number over the old one for some reason rendering it unreadable most of the time

thanks

[lua]

local playedOnce = false

local function ongoBtnPress()

    local color = math.random( 5 )

    

    if playedOnce == false then

    

        local displayedColor = display.newText(color, 300, 20, native.systemFont, 40)

        displayedColor:setTextColor(255, 255, 255)

        

        local playedOnce = true

    else

    

        displayedColor:removeSelf()

    

        local displayedColor = display.newText(color, 300, 20, native.systemFont, 40)

        displayedColor:setTextColor(255, 255, 255)

    

        return true

    end

end

[/lua]

Remove the ‘local’ from playedOnce in your function. When you put local in the function it is different from the ‘local’ outside the code block.

Try this.

local playedOnce = false local displayedColor = display.newText("0", 300, 20, native.systemFont, 40) displayedColor:setTextColor(255, 255, 255) local function ongoBtnPress() local color = math.random( 5 ) if playedOnce == false then displayedColor.text = color playedOnce = true else displayedColor.text = color return true end end

Good Luck!
