[coolian 0]

i want to make a timer call some function after a little bit of time  i use event.timer 

local event = require'timer'

event.timer(2,function() print("do something"),3)

 

that is my code and i get an unexpectet symbol error at ')' wheres the unexpectet symbol how do i need to make that

functions have to have an `end`

local event = require("timer")
event.timer(2, function() print("do something") end,3)
