Buff Timer Question

[stiq]

Hi,
I've never written a WoW-AddOn and I have a question on methodology.

My goal is to build an AddOn that displays in a small frame all of the players dots and/or debuffs on the current target.

I've done some reading and research and I'm pretty sure I see how to get the debuffs, my question is how do I get the constant updates. That is, I can get all the DoT and DeBuff info on a once-off call to UnitDebuff, but how do I accomplish the "timer" part of the equation.

Is it simply a continous loop? Or is there a way to set up a pipe between the player-character and the target?

Thanks in advance.

By using an OnUpdate script

You can hook the cooldown frame of the (de)buff frame.

Take a look how OmniCC does it.
