WA/LUA: show icon if target is in combat

[Deleted]

hey,
i would like my Weak Auras to show an icon when my target is in combat (and another one when hes not).
i think its possible, i found this: http://wowwiki.wikia.com/wiki/API_UnitAffectingCombat
but i have no clue how to turn this into a LUA script, nor how to implement that script into WA.
can anyone point me in the right direction?
thanks a lot

You'd want to go into the Trigger field, make a custom trigger that checks on every frame.

The trigger code is:

function () {
   return UnitAffectingCombat("target");
}

The untrigger code is:

function () {
   return true;
}
