The struct just exsit,But the visual studio just report Unrecognized type -type must be a UCLASS,USTRUCT, or UENUM,I just have import the .h.But why it can’t find the struct?

Thats UnrealHeaderTool error and it happens when it search header files for reflection system macros like USTRUCT, UCLASS etc. and in UPROPERTY or UFUNCTION there is not supported type by unreal reflection system or type that UHT didn’t find to be reflected (missing USTRUCT)

If you can, paste header files with value that error complains about and with decleration of struct you trying to use, so we can try to help you ferther. Remember to use code formatting when you paste code here

Frist,Thank you for help. the following is my code:

MyPlayerController.h

#include “CoreMinimal.h”
#include “H1Z1Character.h”
#include “Interact.h”
#include “GameFramework/PlayerController.h”
#include “MyPlayerController.generated.h”

/**
 * 
 */
UCLASS()
class H1Z1_API AMyPlayerController : public APlayerController
{
	GENERATED_BODY()
	
public:
	UFUNCTION(BlueprintCallable,Category = "Utils")
	void AddItemToInventoryById(FName ID);

	UPROPERTY(BlueprintReadWrite,VisibleAnywhere)
	AInteract  * CurrentInteractable;

	UPROPERTY(BlueprintReadWrite,VisibleAnywhere)
		TArray <FInventoryItem> Inventory;   // ***ERROR:Uncongnized type FInventory, type must be a USTRUCT,UCLASS,UENUM.***

protected:

	void Interact();

	virtual void SetupInputComponent() override;
};
