Hi everyone,

I’ve a problem when I try to compile my code. This is my Output :

1>------ Début de la génération : Projet : ATOMICS_2, Configuration : Development_Game x64 ------

And this is my ABlock class :

UCLASS()
class ATOMICS_2_API ABlock : public AActor
{
	GENERATED_BODY()

protected:
	virtual MeshData FaceDataUp(AChunk& chunk, int x, int y, int z, MeshData meshdata);
	virtual MeshData FaceDataDown(AChunk& chunk, int x, int y, int z, MeshData meshdata);
	virtual MeshData FaceDataNorth(AChunk& chunk, int x, int y, int z, MeshData meshdata);
	virtual MeshData FaceDataSouth(AChunk& chunk, int x, int y, int z, MeshData meshdata);
	virtual MeshData FaceDataEast(AChunk& chunk, int x, int y, int z, MeshData meshdata);
	virtual MeshData FaceDataWest(AChunk& chunk, int x, int y, int z, MeshData meshdata);

public:	

	UPROPERTY(EditAnywhere, BlueprintReadWrite,Category="Attributes")
		TArray<FVector> vertexArray;

	UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Attributes")
		TArray<int32> faceDataArray;

	// Sets default values for this actor's properties
	ABlock();

	virtual bool IsSolid(EDirection direction);


	virtual MeshData BlockData(AChunk& chunk, int x, int y, int z, MeshData meshdata);

	// Called when the game starts or when spawned
	virtual void BeginPlay() override;
	
	// Called every frame
	virtual void Tick( float DeltaSeconds ) override;

	
	
};

I don’t see what is the problem. Can you help me ?

I think my problem is about circular dependency but I can’t avoid them, I don’t know why…

Whats in line 13 of BlockAir.h?

This is my BlockAir.h :

#pragma once

#include "Block.h"
#include "BlockAir.generated.h"


/**
 * 
 */
UCLASS()
class ATOMICS_2_API ABlockAir : public ABlock
{ //this line make an error
	GENERATED_BODY()
	
public:
	
	
	MeshData BlockData(AChunk& chunk, int x, int y, int z, MeshData meshdata) override;

	bool IsSolid(EDirection direction) override ;
	
};

I think it’s about circular dependencies between my Block.h and an other file called Chunk.h
This is the begining of these files :
//Block.h

#pragma once

#include "GameFramework/Actor.h"

#include "Chunk.h"
#include "MeshData.h"

#include "Block.generated.h"


class ATOMICS_2_API AChunk;

UCLASS()//...


//Chunk.h
#pragma once

#include "GameFramework/Actor.h"

#include "MeshData.h"
#include "BlockAir.h"
#include <vector>
#include <memory>

#include "Runtime/Engine/Public/DynamicMeshBuilder.h"
#include "Chunk.generated.h"

#define _CHUNK_SIZE 16

class ATOMICS_2_API ABlock;

UCLASS()//...

try changing int to int32
