How do you use FDataTableRowHandle and FindRow

I wanna know if this is fixed. I am brain f@(ked by UDataTable. For now, I am using blueprints as Implementable. It shows same read access violation. Here’s my latest code with Enum and Strings corrected and checked properly:


FMovementParameter UULib::CalculateSpeed(UDataTable* movementTable, EStances stance,
	EFootplacements footCondition, EWeaponary weaponCondition, EMood mood)
{
	FMovementParameter result = FMovementParameter::FMovementParameter();

	// Stance:
	FMovementParameter* stanceParameter = movementTable->FindRow<FMovementParameter>(UEnum::GetValueAsName(stance), "", true);
	FName stanceParameterName = UEnum::GetValueAsName(stance);
	stanceParameter = movementTable->FindRow<FMovementParameter>(stanceParameterName, "", true);

	// Foot:
	FMovementParameter* footParameter = movementTable->FindRow<FMovementParameter>(UEnum::GetValueAsName(footCondition), "", true);
	FName footParameterName = UEnum::GetValueAsName(footCondition);
	footParameter = movementTable->FindRow<FMovementParameter>(FName(footParameterName), "", true);

	// WeaponParameter:
	FMovementParameter* weaponParameter = movementTable->FindRow<FMovementParameter>(UEnum::GetValueAsName(weaponCondition), "", true);
	FName weaponParameterName = UEnum::GetValueAsName(weaponCondition);
	weaponParameter = movementTable->FindRow<FMovementParameter>(FName(weaponParameterName), "", true);

	// Mood
	FMovementParameter* moodParameter = movementTable->FindRow<FMovementParameter>(UEnum::GetValueAsName(mood), "", true);
	FName moodParameterName = UEnum::GetValueAsName(mood);
	moodParameter = movementTable->FindRow<FMovementParameter>(FName(moodParameterName), "", true);


	UULib::PrintMessaged(FString::SanitizeFloat(stanceParameter->uSpeed), 10.0f);
	UULib::PrintMessaged(FString::SanitizeFloat(footParameter->uSpeed), 10.0f);
	UULib::PrintMessaged(FString::SanitizeFloat(weaponParameter->uSpeed), 10.0f);
	UULib::PrintMessaged(FString::SanitizeFloat(moodParameter->uSpeed), 10.0f);

	result.uSpeed = stanceParameter->uSpeed * footParameter->uSpeed * weaponParameter->uSpeed * moodParameter->uSpeed;
	result.uHeight = stanceParameter->uHeight;
	result.uStaminaLoss = stanceParameter->uStaminaLoss * weaponParameter->uStaminaLoss * moodParameter->uStaminaLoss ;
	result.uCameraFOV = stanceParameter->uCameraFOV * footParameter->uCameraFOV * weaponParameter->uCameraFOV * moodParameter->uCameraFOV;
	result.uCameraShake = stanceParameter->uCameraShake * footParameter->uCameraShake * weaponParameter->uCameraShake;

	return result;
}

Edit:
I don’t understand WTF read access violation comes to do. I tried Administrator permissions on. Still same. Unreal Engine crashes :frowning: with read access violation.
