Delays between trigger firings

Hello,

I think there used to be a video on youtube for making delays between trigger firings (in the example, the trigger would go off everytime the person got a tell). I can't find that video anymore, though, but I would like to use something similar in a trigger.

I thought about using the 'wait' function instead, but the way shown in the video was cleaner, and I think used OS time somehow.

Can someone give an example of how to cause a trigger to delay, say, 10 seconds between firings?

It was probably DoAfter ...

Or you could check inside the trigger script (assuming it sent to script) if 10 seconds had elapsed, and if not, just return, doing nothing.

I'm fairly sure it wasn't do after. It was an if check using os.time, I'm just not sure how to do it.

A vague idea of how it went was

trigger name: * tells you *

trigger body:

if (os.time since last tell > 30 seconds) then
PlaySound("alert")

else
--do nothing

end

It's how to do/make that 'if' statement work that I'm having trouble with.

Honestly, I think you may have been the one to have made the video on YouTube, but I can't find it anymore.

Something like http://gammon.com.au/forum/bbshowpost.php?id=10967 perhaps?
