# Inventory
Methods to interact with the inventory gametab.

```

## TRSInventory
Main record responsible with handling the inventory gametab.


- - -

## Inventory.SetupGameTab
```pascal
procedure TRSInventory.SetupGameTab();
```
Internal method used to setup the {ref}`TRSInventory` coordinates.

This is automatically called for you on the {ref}`Inventory variable`.


- - -

## Inventory.IsOpen
```pascal
function TRSInventory.IsOpen(): Boolean;
```
Returns true/false if the inventory is open.

Example:
```pascal
WriteLn Inventory.IsOpen();
```


- - -

## Inventory.Open
```pascal
function TRSInventory.Open(): Boolean;
```
Attempts to open the inventory gametab.

Example:
```pascal
WriteLn Inventory.Open();
```


- - -

## Inventory.IsFull
```pascal
function TRSInventory.IsFull(): Boolean;
```
Returns true/false if the inventory is full.

Example:
```pascal
WriteLn Inventory.IsFull();
```


- - -

## Inventory.IsSelected
```pascal
function TRSInventory.IsSelected(slot: TBox): Boolean;
function TRSInventory.IsSelected(slot: Integer): Boolean; overload;
function TRSInventory.IsSelected(item: TRSItem): Boolean; overload;
```
Returns true/false if the specified `slot` or `item` is currently selected.

Example:
```pascal
WriteLn Inventory.IsSelected('Vial');
```


- - -

## Inventory.GetSelected
```pascal
function TRSInventory.GetSelected(): Integer;
```
Returns the selected slot number if any. -1 is returned if no selected slot is found.

Example:
```pascal
WriteLn Inventory.GetSelected();
```


- - -

## Inventory.Select
```pascal
function TRSInventory.Select(slot: Integer; wait: Boolean = False): Boolean;
function TRSInventory.Select(item: TRSItem; wait: Boolean = False): Boolean; overload;
```
Attempts to select the specified `slot` or `item`.
If `wait` is set to true we wait for confirmation that we succeeded.

Example:
```pascal
WriteLn Inventory.Select('Coins');
```


- - -

## Inventory.Combine
```pascal
function TRSInventory.Combine(slotA, slotB: Integer): Boolean;
function TRSInventory.Combine(itemA, itemB: TRSItem): Boolean; overload;
```
Attempts to combine 2 slots or 2 items.

Example:
```pascal
WriteLn Inventory.Combine('Coins', 'Asgarnian ale');
```


- - -

## Inventory.Drop
```pascal
function TRSInventory.Drop(slots: TIntegerArray; attempts: Integer = 5): Boolean;
function TRSInventory.Drop(items: TRSItemArray; pattern: TIntegerArray = []): Boolean; overload;
```
Attempts to drop the specified `slots` or `items`.

Example:
```pascal
WriteLn Inventory.Drop('Oak logs');
```


- - -

## Inventory.ShiftDrop
```pascal
function TRSInventory.ShiftDrop(slots: TIntegerArray; attempts: Integer = 5): Boolean;
function TRSInventory.ShiftDrop(slots, pattern: TIntegerArray): Boolean; overload;
function TRSInventory.ShiftDrop(items: TRSItemArray; pattern: TIntegerArray): Boolean; overload;
```
Attempts to shift drop the specified `slots` or `items`.  You can optionally specify a "drop" pattern.
If we determine that we can't shift drop because the setting is off, `TRSInventory.Drop()` is used as a fallback.

Example:
```pascal
WriteLn Inventory.ShiftDrop('Maple logs');
```

## Inventory variable
Global {ref}`TRSInventory` variable.
