Timer picking among certain functions

#1

Hello guys I would like to know how to make this timer pick among 4 different functions.

Right now the timer is set to spawnObj1 as the function

spawnTimer = timer.performWithDelay( 5000, spawnObj1, 1 )

#2

You could set the timer to call a function that then does the picking, for instance,

 

local function pickFunction() local int = math.random(4) if int == 1 then spawnObj1() elseif int == 2 then spawnObj2() elseif int == 3 then spawnObj3() else spawnObj4() end end spawnTimer = timer.performWithDelay( 5000, pickFunction, 1 )
