lua - Adding a delay/timer -

this question has answer here:

• lua program delay 1 answer

i using corona sdk, lua main language. having problem code - when run it, automatically gives me values of 'light' in stated print out. set light = 2 , loop, supposed decrement light 1 each time, until <= 0. when run program, values show 1,0,-1 @ once. wondering if can add delay between each values.

i making "simon says" game, , because of this, boxes not light because runs @ once.

here code:

if(count%20 == count - math.floor(count/20)*20)     clicked = 0      while(light >= 0)         light = light - 1         print(light)     end end  

here simple timer.performwithdelay function of corona sdk. can view more here: https://docs.coronalabs.com/api/library/timer/performwithdelay.html

below sample code suits question.

note: based code presented code above.

local lights = 2 local timername -- add timer id timer can cancel later on  local function myfunction()      lights =  lights - 1      if (lights >= 0)         --do lights         print(lights)     else          --terminate timer         timer.cancel( timername )      end  end    if(count%20 == count - math.floor(count/20)*20)      timername = timer.performwithdelay( 1000, myfunction, 0 )    end
