Unreal c++ Call a void from a Actor With LineTrace

Im new to c++ (use to c#) and trying to call a void on a Actor when it gets hit with a raycast and send it the cords. Heres the script header that im trying to call "EditMesh" on (near the bottom)

Im new to c++ (use to c#) and trying to call a void on a Actor when it gets hit with a raycast and send it the cords. Heres the script header that im trying to call "EditMesh" on (near the bottom)

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);
};

And here is part of the cpp of the other script that I want to call EditMesh() with

        #include "Chunk.h"
        #include "VoxelWarsCharacter.h"
        #include "VoxelWarsProjectile.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?????????
    }
}

Errors I get
