How would i do this? Timing server side for strategy game

[Olliepop]

Hey guys

So at the moment i'm making an online strategy game a bit like tribalwars.net.

I'm having a problem with building construction, unit recruitment, travel times etc.

For example..

When a user clicks "build" for a building, the building will be added to a queue and will be completed in X seconds.

How will i do this server-side? How does tribalwars.net and other games do these queues?

Thanks very much :]

what language are you using?
If you are using php you can use sleep() function

to make the pphp stop for x seconds and then start again when the building time is complete

Doing this via php can be tricky. Using Ajax also poses problems, as it is asynchronous - queuing requires extra coding. Using the server for this can be a little intensive - Perhaps having data updated immediately in php and then using js (if that's what you're using) to sort out the delay?
