Random Background colors

Getting Started Newbie Questions
#1

I am trying to making the background change colors randomly, here is the code that I am using, what am I doing wrong?

 local background = display.setDefault( "background", math.random(1, 255), math.random(1, 255), math.random(1, 255) )
#2

Colors are now in a range of 0…1, not  0…255.  If you call math.random() without passing in any parameters you will get a number between 0 and 1 which you can use for the background.

Thank you Rob, but how do I make it so the background color also changes every 10 seconds?

#4

Set up a timer that calls a function to change the colour.
 

local background function bgChange() background = display.setDefault( "background", math.random(0,1), math.random(0,1), math.random(0,1) ) end bgTimer = timer.performWithDelay( 10000, bgChange, -1)

it’s preferred to do it this way :

local  background = display.setDefault( “background”, math.random(0,1), math.random(0,1), math.random(0,1) )

function bgChange()
    background:setFillColor(math.random(0,1), math.random(0,1), math.random(0,1))

end

bgTimer = timer.performWithDelay( 10000, bgChange, -1)

this way you’ll avoid some memory issues that may occur on low devices.
