AActor::OnTakeRadialDamage

property Engine Blueprint Since 4.0

#include "GameFramework/Actor.h"

Access: public Specifiers: UPROPERTYBlueprintAssignable

Description

Delegate broadcast when this actor takes radial (area-of-effect) damage, providing the explosion origin and a hit result for the closest impacted primitive. Used for explosion and AoE effects.

Caveats & Gotchas

• Only fires on the server. Like other damage delegates, client-side effects require separate replication.
• Radial damage uses a falloff model — the Damage parameter already reflects the falloff-adjusted value at this actor's distance from the origin, not the raw damage passed to ApplyRadialDamage.

Example

React to explosion damage with knockback C++

OnTakeRadialDamage.AddDynamic(this, &AMyActor::HandleRadialDamage);

void AMyActor::HandleRadialDamage(AActor* DamagedActor, float Damage,
    const UDamageType* DamageType, FVector Origin,
    const FHitResult& HitInfo, AController* InstigatedBy, AActor* DamageCauser)
{
    FVector KnockDir = (GetActorLocation() - Origin).GetSafeNormal();
    // Apply impulse or movement...
}
