# Slot Selection & Scrolling

> Set the selected slot:

### Selection (Blueprint)

Set the selected slot:

```
Set Selected Slot
   Slot Index = X
```

Get the current selection:

```
Get Selected Slot
→ int32
```

Check if a given slot is selected:

```
Is Slot Selected
   Slot Index = X
   Return     = true/false
```

### Selection (C++)

```
HotbarComponent->SetSelectedSlot(DesiredIndex);

int32 Selected = HotbarComponent->GetSelectedSlot();

bool bSelected = HotbarComponent->IsSlotSelected(SomeIndex);
```

***

### Responding to Selection Changes

Blueprint Event

In HotbarComponent or listening Blueprint:

```
Event On Slot Selection Changed
   New Selected Slot = Index
   ↓
Update UI highlight
   ↓
Optionally: Equip weapon / update action
```

C++

```
HotbarComponent->OnSlotSelectionChanged.AddDynamic(this, &AMyClass::HandleSelectionChanged);

void AMyClass::HandleSelectionChanged(int32 NewSlot)
{
    // Example: update UI and/or equip
    HotbarUI->HighlightSlot(NewSlot);
}
```

### Scroll Through Hotbar (C++ Example)

```
void AMyCharacter::ScrollHotbar(float Delta)
{
    int32 CurrentSlot = HotbarComponent->GetSelectedSlot();
    int32 MaxSlots    = HotbarComponent->MaxSlots;

    int32 NewSlot = CurrentSlot;

    if (Delta > 0)
    {
        NewSlot = (CurrentSlot + 1) % MaxSlots;
    }
    else if (Delta < 0)
    {
        NewSlot = (CurrentSlot - 1 + MaxSlots) % MaxSlots;
    }

    HotbarComponent->SetSelectedSlot(NewSlot);
}
```

In Blueprint you’d mirror this with:

```
Get Selected Slot
   ↓
Add/Subtract (based on scroll input)
   ↓
Modulo by MaxSlots
   ↓
Set Selected Slot
```
