Trouble understand structs

[Emu.Man00]

So I have a function that runs every second after a unit starts channeling, and I need to reference the triggering unit inside this function. I also need to know when it stops casting, to stop the function from running.

To my understanding structs are the best way to do this, but I can't seem to understand how to use them at all...

All help is appreciated...

It is no need struct... Struct is like a class, having students inside.. It is good for attaching since you just need integer to pass with. My method in channeling spell is constantly put GetUnitCurrentOrder block.
