Note that you must declare a variable before registering a callback if you want to use CancelToken in the callback. Otherwise, nil will be returned.
local cancelToken
-- Print the log in 2 seconds. Then print the log every second.
cancelToken = YaTimeAPI.ScheduleAtInterval(2, 1, function()
metCounter = metCounter + 1
print("Hey! We have met " .. metCounter .. " times")
-- Cancel the registration of the callback when the execution number reaches totalTimesToMeet and the callback is terminated.
if metCounter == totalTimesToMeet then
cancelToken:Cancel()
end
end)
