Enum转FString

示例：

//打印为 “NormalAttack”
FString EnumName = StaticEnum<EAttackCategory>()->GetNameStringByValue(static_cast<int64>(AttackCategory)));


//打印为 “EAttackCategory::NormalAttack”
FString EnumName = StaticEnum<EAttackCategory>()->GetValueAsName(static_cast<int64>(AttackCategory)));

示例2：

//.h
EAttackCategory AttackType;

//.cpp
//打印为 “NormalAttack”
static const UEnum* EnumType = FindObject<UEnum>(ANY_PACKAGE, TEXT("EAttackCategory"));
FString EnumName = EnumType->GetNameStringByIndex(static_cast<uint32>(AttackType)));

//或
FString AEnumTest::GetEnumName(FINTLFunnelStep InStep)
{
	UEnum* Enum = StaticEnum<FINTLFunnelStep>();
	FName name = Enum->GetNameByIndex(InStep);

	//打印为 “name=kEnterGameShowEnterGame”
	UE_LOG(LogTemp, Warning, TEXT("name=%s"),*name.ToString());
	return name.ToString();
}

int32转Enum

示例：

TEnumAsByte<EGameplayModOp::Type> FCalculateData::GetModifierOp(int32 inModifierOp)
{
	return static_cast<EGameplayModOp::Type>(inModifierOp);
}
