What is the best way for P2 to know who is the attacker or attacker ID in Ikemen?

[beterhans]

current workaround for me
put attacker id in hitdef parameters

let victim to get it by using gethitvar()
but sometime cause issue in ikemen

Ikemen introduced a new GetHitVar(ID) trigger. It returns the ID of the player that hit you.
