FRadialDamageEvent doesn't work? Help!

Hey,

I want to create a AOE damage effect and tried it With the FRadialDamageEvent.
It’s possible to assign some parameters with the FRadialDamageParams .

FRadialDamageEvent dmg_event;

FRadialDamageParams params;

params.BaseDamage = 100.0;
params.OuterRadius = 500.0;

dmg_event.params = params;
dmg_event.Origin = GetActorLocation();

actor->TakeDamage(damage,dmg_event,Instigator,Causer);

I’m not quite sure about the damage?
there is a damage value at for TakeDamage and another one for the Radial base damage.
I also have no idea about the 2 radius values (outer/inner)

Anyway, when TakeDamage is called, only the target actor takes damage and the actors around him do not.

can anyone help me to create a AOE effect.

Look on the UGameplayStatics::ApplyRadialDamage as a reference or use it.
