AActor::ReceiveRadialDamage
#include "GameFramework/Actor.h"
Access: protected
Specifiers: UFUNCTIONBlueprintImplementableEventBlueprintAuthorityOnly
Description
Blueprint implementable event called on the server when this actor takes radial (AoE) damage. Provides the explosion origin and hit result so you can compute directional knockback or distance-based reactions.
Caveats & Gotchas
- • Authority-only: this event will not execute on clients. Drive client-visible effects through a replicated property or multicast RPC.
- • DamageReceived is already falloff-adjusted by the time this event fires. You cannot recover the raw base damage from within this event.
