# Working With Attributes in C++

This page mirrors your UMF style: simple examples with short explanations.

***

## **Accessing the Component**

```
UAttributeManagerComponent* Attr = FindComponentByClass<UAttributeManagerComponent>();
```

***

## **Reading Attribute Values**

```
float Health = Attr->GetAttributeValue("Health");
float Stamina = Attr->GetAttributeValue(FName("Stamina"));
```

***

## **Modifying Attributes**

```
Attr->AddToAttribute("Health", 25.f);
Attr->SubtractFromAttribute("Stamina", 10.f);
Attr->SetAttributeValue("Defense", 50.f);
```

Under the hood:

* Modifiers are validated
* Link definitions re-evaluate
* Replication updates clients
* Relevant events fire

***

## **Applying Effects**

```
Attr->ApplyEffect(EffectDefinition, Instigator);
```

Effects come from `UEffectDefinition` assets.

***

## **XP & Leveling**

```
Attr->AddXP("Logging", 50.f);
int32 NewLevel = Attr->GetAttributeLevel("Logging");
```

XP uses curve tables defined in the profile’s progression config.

***

## **Listening for Events**

Typical method:

```
Attr->OnAttributeChanged.AddDynamic(this, &ThisClass::HandleChange);
```

Or performance version (preferred):

```
Attr->OnAttributeChangedNative.AddUObject(this, &ThisClass::HandleChange);
```

***

## **Full C++ Example**

```
void AMyCharacter::ConsumeStamina(float Amount)
{
    if (auto* Attr = FindComponentByClass<UAttributeManagerComponent>())
    {
        Attr->SubtractFromAttribute("Stamina", Amount);

        if (Attr->GetAttributeValue("Stamina") <= 0)
        {
            // Character is exhausted
        }
    }
}
```

## **Developer Notes**

* All internal maps use `FName` handles for speed.
* Modifiers and effects are executed in deterministic order.
* C++ offers better performance for rapid-fire attribute updates (combat, stamina drain).
* Every call is multiplayer-safe by default.
