Hey lovely People, So I created a Weapon pick up in C++ and I have just added Animations now however when I play animations and then play it again my weapon disappears. Here is the following File I created:
Weapon.H:
#pragma once
#include “CoreMinimal.h”
#include “Item.h”
#include “Weapon.generated.h”
UENUM(BlueprintType)
enum class EWeaponState : uint8
{
EWS_Pickup UMETA(DisplayName “Pickup”),
EWS_Equipped UMETA(DisplayName “Equipped”),
EWS_MAX UMETA(DisplayName “DefaultMax”)
};
/**
*
*/
UCLASS()
class FIRSTPROJECT_API AWeapon : public AItem
{
GENERATED_BODY()
public:
AWeapon();
UPROPERTY(VisibleAnywhere, BlueprintReadWrite, Category = “Item”)
EWeaponState WeaponState;
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = “Item | Particle”)
bool bWeaponParticle;
UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = “Item | Sound”)
class USoundCue* OnEquipSound;
UPROPERTY(VisibleAnywhere, BlueprintReadWrite, Category = “SkeletalMesh”)
class USkeletalMeshComponent* SkeletalMesh;
virtual void OnOverlapBegin(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult & SweepResult) override;
virtual void OnOverlapEnd(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex) override;
void Equip(class AMain* Char);
FORCEINLINE void SetWeaponState(EWeaponState State) { WeaponState = State; }
FORCEINLINE EWeaponState GetWeaponState() { return WeaponState; }
};
Weapon.CCP:
#include “Weapon.h”
#include “Components/SkeletalMeshComponent.h”
#include “Main.h”
#include “Engine/SkeletalMeshSocket.h”
#include “Sound/SoundCue.h”

AWeapon::AWeapon()
{
SkeletalMesh = CreateDefaultSubobject<USkeletalMeshComponent>(TEXT(“Skeletal Mesh”));
SkeletalMesh->SetupAttachment(GetRootComponent());
bWeaponParticle = false;
WeaponState = EWeaponState::EWS_Pickup;
}
void AWeapon::OnOverlapBegin(UPrimitiveComponent* OverlappedComponent, AActor* OtherActor, UPrimitiveComponent* OtherComp, int32 OtherBodyIndex, bool bFromSweep, const FHitResult & SweepResult)
{

if ((WeaponState == EWeaponState::EWS_Pickup) && OtherActor)
{

}
}
}

{

if (Main)
{

}
}
}
void AWeapon::Equip(AMain* Char)
{
if (Char)
{
SkeletalMesh->SetCollisionResponseToChannel(ECollisionChannel::ECC_Camera, ECollisionResponse::ECR_Ignore);
SkeletalMesh->SetCollisionResponseToChannel(ECollisionChannel::ECC_Pawn, ECollisionResponse::ECR_Ignore);
SkeletalMesh->SetSimulatePhysics(false);
const USkeletalMeshSocket* RightHandSocket = Char->GetMesh()->GetSocketByName(“RightHandSocket”);
if (RightHandSocket)
{
RightHandSocket->AttachActor(this, Char->GetMesh());
bRotate = false;
Char->SetEquippedWeapon(this);

}
