'OnOverlap' does not look like a member

Development Programming & Scripting

Hi
I Want Add OnComponentOverlap Event

This Is My Code

oid AAttackComponentLoader::AddAttackComp( const FName& AttachSocketName, AMonsterBase* Parent, float InRadius, float InHalfHeight ) {

	UAttackComponent* AttackComp = NewObject<UAttackComponent>( UAttackComponent::StaticClass());
	AttackComp->Init( );

}



//AttackComp->Init( ) 

void UAttackComponent::Init( ) {
	OnComponentBeginOverlap.__Internal_AddDynamic( this, &UAttackComponent::OnOverlap, TEXT( "OnOverlap" ) );

}

This is Error

Unknown exception - code 00000001 (first/second chance not available)

What Should I Do?

2

Inside your UAttackComponent header file add the below method:

void OnComponentOverlapBegin(class AActor* OtherActor, class UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult & SweepResult);

then in your UAttackComponent source file add definition for the above function. Then in your Init function you can add this to bind the delegate.

OnComponentBeginOverlap.AddDynamic(this, &UAttackComponent::OnComponentOverlapBegin);

To add further clarity to this:

You shouldn’t be using “__Internal_AddDynamic” directly. Leave that to the AddDynamic macro.
