this is a repost, start a countdown timer when run a command and switch to another timer when the number hits zero
I think whatever you are asking this for could probably be done in a simpler way, but probably something to this effect: Listen for Command, then start FirstTask. When FirstTask is run, call firstTaskComplete in the main class. In that method, start SecondTask. Resources: Tasks/Timers Commands
Then start a Task if the command is called. Links to help you with creating Tasks have already been posted above.
