Pokemon effects from damage counter placement from attcks

[Darkwalker]

There are a number of pokemon that place damage counters onto your opponent's benched pokemon via their attack, Froslass is a good example for this (40 damage and sleep to the defending pokemon, place 1 damage counter on each bench pokemon). Other pokemon have effects that trigger when they are damaged the turn before, such as Bastiodon (Anger Revenge : if Bastiodon was damaged by an attack during your opponent's last turn this attack does 40 damage to 1 of your opponent's Benched Pokemon). Poliwrath's Focus Punch has similar wording, but with a detrimental effect.

My question is do damage counters placed via attack trigger effects worded like the ones above; or since it is damage counters being placed, instead of actual damage, are those conditional effects ignored?

Don't confuse damage calculations with effects.
Effects are what is actually done.
Damage calculations tell you how to determine what to do.

An attack can place counters or do damage.
Or, rarely, do some of both.

It doesn't matter how you come about figuring out the amount of damage or number of damage counters. All that matters is if you are doing damage or placing counters.

Guard will block the placing of counters and will not block damage done. It doesn't matter how you figured out how much to do of each.
