Solved 'Pausing' a scheduled delayed task

Whats the best/easiest way of pausing a scheduled delayed task when a player leaves (it starts when the player joins).

I.O.W only have it countdown while the player is online.

I get that feeling there isn't really an easy way :/ Maybe passing the countdown to a player leave event or something, but I'm lost after there.

 

Scullyking Possibly make a if statement checking if the player is online.

 

But when they leave it will still remove the countdown. I want it to pause when they leave and un-pause when they join.

EDIT: I see what you mean, this will work thankyou!

 

Scullyking I don't know if there is a thread-safe way of doing this. Possibly, you could run wait() on the task when the player leaves and run notify() when the player joins, but I don't know how that would work out on a synchronous thread.

 

Scullyking if that doesn't work try this

Niknea The problem with sleep() is that it can't be woken up by a certain process.

Thanks both for the help, I re-structured some stuff with my plugin so that Kiknea's suggestion of checking if the player is online would work
