Multiple Collision Functions?

Development Programming & Scripting

Hello!!

I want to have two different overlap functions for two different components in C++, for some reason, I can’t get this to work. The body collision works, but the fist ones dont. any ideas what is happening or what I am missing?

.h

    	//Collision function for the fists
    	UFUNCTION()
    	void FistCollision(AActor *OtherActor, UPrimitiveComponent *OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult &SweepResult);

	//Collision function for the Character
	UFUNCTION()
	void BodyCollision(AActor *OtherActor, UPrimitiveComponent *OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult &SweepResult);

	UFUNCTION()
	void BodyCollisionExit(AActor *OtherActor, UPrimitiveComponent *OtherComp, int32 OtherBodyIndex);

.cpp

	//Create a collision for the right hand/fist
	RightFistCollision = ObjectInitializer.CreateDefaultSubobject<UBoxComponent>(this, TEXT("RightFistCollision"));
	RightFistCollision->AttachTo(GetMesh(), "RightHandSocket");
	RightFistCollision->OnComponentBeginOverlap.AddDynamic(this, &ABornImmortalCharacter::FistCollision);
	RightFistCollision->SetCollisionProfileName(TEXT("NoCollision"));

	//Create a collision for the left hand/fist
	LeftFistCollision = ObjectInitializer.CreateDefaultSubobject<UBoxComponent>(this, TEXT("LeftFistCollision"));
	LeftFistCollision->AttachTo(GetMesh(), "LeftHandSocket");
	LeftFistCollision->OnComponentBeginOverlap.AddDynamic(this, &ABornImmortalCharacter::FistCollision);
	LeftFistCollision->SetCollisionProfileName(TEXT("NoCollision"));

	CollisionComp = ObjectInitializer.CreateDefaultSubobject<UBoxComponent>(this, TEXT("CollisionComp"));
	CollisionComp->AttachTo(RootComponent);
	CollisionComp->OnComponentBeginOverlap.AddDynamic(this, &ABornImmortalCharacter::BodyCollision);
	CollisionComp->OnComponentEndOverlap.AddDynamic(this, &ABornImmortalCharacter::BodyCollisionExit);

//FUNCTION FOR FIST COLLISIONS
void ATestCharacter::FistCollision(AActor *OtherActor, UPrimitiveComponent *OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult &SweepResult)
{
	if (OtherActor && OtherActor != this)
	{
		GEngine->AddOnScreenDebugMessage(-1, 2.f, FColor::Red, "Derp");
		ATestActor *Char = Cast<ATestActor>(OtherActor);
		if (Char)
		{
			Char->GetMesh()->AddImpulseAtLocation(FVector(0, 0, 10000), Char->GetActorLocation());
			GEngine->AddOnScreenDebugMessage(-1, 2.f, FColor::Red, "Ouch");
		}
		AEnemy *Enemy = Cast<AEnemy>(OtherActor);
		if (Enemy)
		{
			Enemy->GetMesh()->AddImpulseAtLocation(FVector(0, 0, 10000), Enemy->GetActorLocation());
			GEngine->AddOnScreenDebugMessage(-1, 2.f, FColor::Red, "Derp");
		}
	}
}

void ATestCharacter::BodyCollision(AActor *OtherActor, UPrimitiveComponent *OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult &SweepResult)
{
	AWeapon *Weapon = Cast<AWeapon>(OtherActor);
	if (OtherActor && OtherActor != this)
	{
		if (Weapon)
		{
			GEngine->AddOnScreenDebugMessage(-1, 2.f, FColor::Red, "Enter");
			bIsWeaponPickup = true;
			WeaponPickup = Weapon;
		}
	}
}

void ATestCharacter::BodyCollisionExit(AActor *OtherActor, UPrimitiveComponent *OtherComp, int32 OtherBodyIndex)
{
	AWeapon *Weapon = Cast<AWeapon>(OtherActor);
	if (OtherActor && OtherActor != this)
	{
		if (Weapon)
		{
			GEngine->AddOnScreenDebugMessage(-1, 2.f, FColor::Red, "EXIT");
			bIsWeaponPickup = false;
			WeaponPickup = NULL;
		}
	}
}

KEEP IN MIND

I also turn on and off the “NoCollision” and switch it to “OverlapAllDynamic” when the fist attack happens
