虚幻c++使用LineTrace从Actor调用一个void

我是 c++ 的新手（用于 c#），当 Actor 被光线投射击中并向其发送绳索时，尝试在 Actor 上调用空洞。这是我尝试调用"EditMesh"的脚本标头（靠近底部）

 #pragma once
    #include "CoreMinimal.h"
    #include "GameFramework/Actor.h"
    #include "ProceduralMeshComponent.h"
    //#include "Core.h"
    #include "Chunk.generated.h"


    UCLASS()
    class VOXELWARS_API AChunk : public AActor 
    {
        GENERATED_BODY()
    public:
        // Sets default values for this actor's properties
        AChunk();
    protected:
        // Called when the game starts or when spawned
        virtual void BeginPlay() override;

    public:
        // Called every frame
        //virtual void Tick(float DeltaTime) override;
        //UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = Default)
        //  UMaterialInterface* TheMaterial;
        UPROPERTY(EditAnywhere)
            AChunk* ChunkRef; 
        UPROPERTY(EditAnywhere)
            class UMaterialInterface* OnMaterial;
        UPROPERTY(VisibleAnywhere)
    UProceduralMeshComponent * mesh;
        UPROPERTY(VisibleAnywhere)
    int faceCount = 0;
    TArray<FVector> vertices;
    UPROPERTY(VisibleAnywhere)
    TArray<int32> Triangles;
    TArray<FVector> normals; 
    TArray<FVector2D> UV0;
    TArray<FProcMeshTangent> tangents;
    TArray<FLinearColor> vertexColors;
    TArray<FVector2D> blocks; 
    int worldData[16][16][16] = { {} };
    float tUnit = 0.0625; 

    public:void CubeTop(int x = 0, int y = 0, int z = 0, int block = 0);
    public:void CubeNorth(int x = 0, int y = 0, int z = 0, int block = 0);
    public:void CubeEast(int x = 0, int y = 0, int z = 0, int block = 0);
    public:void CubeSouth(int x = 0, int y = 0, int z = 0, int block = 0);
    public:void CubeWest(int x = 0, int y = 0, int z = 0, int block = 0);
    public:void CubeBot(int x = 0, int y = 0, int z = 0, int block = 0);
    public:void Cube(FVector2D texturePos);
    public:void UpdateMesh(); 
    public:void ClearMeshData(); 
    public:void GenMesh();
    public:void EditMesh(int x = 0, int y = 0, int z = 0, int block = 0); //here
    public:int Chk(int x = 0, int y = 0, int z = 0);
    //     int* mBlock(int x = 0, int y = 0, int z = 0);
    };

这是我想调用 EditMesh（） 的另一个脚本的 cpp 的一部分

        #include "Chunk.h"
        #include "VoxelWarsCharacter.h"
        #include "VoxelWarsProjectile.h"
        #include "Animation/AnimInstance.h"
        #include "Camera/CameraComponent.h"
        #include "Components/CapsuleComponent.h"
        #include "Components/InputComponent.h"
        #include "GameFramework/InputSettings.h"
        #include "HeadMountedDisplayFunctionLibrary.h"
        #include "Kismet/GameplayStatics.h"
        #include "MotionControllerComponent.h"
        #include "XRMotionControllerBase.h" // for 
    void AVoxelWarsCharacter::OnFire()
    {
        FVector StartLocation = GetActorLocation(); //your location 
        StartLocation.Z += 15; 
        FVector EndLocation = StartLocation + (FirstPersonCameraComponent->GetForwardVector() * 4000.f); //get forward dir
        FHitResult Hit;
        FCollisionQueryParams ColParms; //ignor stuff
        ColParms.AddIgnoredActor(this);//ignor hitting self
        GetWorld()->LineTraceSingleByChannel(Hit, StartLocation, EndLocation, ECC_Visibility, ColParms);//ECC_WorldDynamic will only hit Actors, ECC_Visibility is everything
        if (Hit.GetActor()) {
            //Hit.GetActor()->AChunk::EditMesh(0, 0, 0, 1);
            GEngine->AddOnScreenDebugMessage(-1, 5.f, FColor(255,255,255), "Hit a actor");
            UKismetSystemLibrary::DrawDebugLine(GetWorld(), StartLocation, Hit.Location, FColor(255, 255, 0), 5, 1);//FColor::Red 
            Hit.GetActor()->FindComponentByClass<AChunk>()->EditMesh((int)Hit.Location.X, (int)Hit.Location.Y, (int)Hit.Location.Z, 0); 
           //How do I do this?????????
        }
    }

我得到的错误
