Sync code with in-game attack animation?

[LudiusMaximus]

How can I make my code execute something exactly in the moment the player attacks something?

I tried the COMBAT_LOG_EVENT_UNFILTERED event, but this appears to happen a noticeabe time before the in-game model actually swings at the target and the damage is displayed in-game.

playerGuid = UnitGUID("player")
local eventFrame = CreateFrame("Frame")
eventFrame:RegisterEvent("COMBAT_LOG_EVENT_UNFILTERED")
eventFrame:SetScript("OnEvent", function(_, ...)
 
  timestamp, subevent, hideCaster, sourceGUID, sourceName, sourceFlags, sourceRaidFlags, destGUID, destName, destFlags, destRaidFlags = CombatLogGetCurrentEventInfo()
  if sourceGUID == playerGuid then
  
    local amount, critical
    if subevent == "SWING_DAMAGE" then
      amount, _, _, _, _, _, critical = select(12, CombatLogGetCurrentEventInfo())
    elseif subevent == "SPELL_DAMAGE" then
      _, _, _, amount, _, _, _, _, _, critical = select(12, CombatLogGetCurrentEventInfo())
    else
      return
    end
 
    -- This comes noticeably earlier than the in-game action takes place.
    -- But I want it to happen exactly at the same time as the in-game action.
    print(amount, critical)
    
  end
end)
