UE C++中使用结构体

创建结构体

简单结构体

USTRUCT()
struct FMyFirstStruct
{
	GENERATED_USTRUCT_BODY()
	
	UPROPERTY()
	FName Name = FName("");

	UPROPERTY()
	float exp = 0;
};

与蓝图交互结构体

USTRUCT(BlueprintType)
struct FMyFirstStruct
{
	GENERATED_USTRUCT_BODY()

	UPROPERTY(EditDefaultsOnly, BlueprintReadWrite, Category="Default")
	FName Name = FName("");

	UPROPERTY(EditDefaultsOnly, BlueprintReadWrite, Category="Default")
	float exp = 0;
};

使用结构体

声明：

UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "Default")
		FMyFirstStruct FirstStruct;

在cpp里输出Struct的内容

UE_LOG(LogTemp, Warning, TEXT("FirstStructName: %s All"), *(FirstStruct.Name.ToString()));

UE_LOG(LogTemp, Warning, TEXT("FirstStructName %s All"), *(FirstStruct.Name.ToString()));
