# Shop
Methods to interact with the shop interface.
```{figure} ../../images/shop_interface.png
```


- - -

## ERSShopQuantity
```pascal
ERSShopQuantity = enum(ONE, FIVE, TEN, FIFTY);
```
Enum representing the shop quantity buttons.


- - -

## TRSShop
Main record to interact with the {ref}`Shop` interface.


- - -

## Shop.FindItemBoundaries
```pascal
function TRSShop.FindItemBoundaries(): TBoxArray;
```
Finds item boundaries and returns them as a TBoxArray.

You have 2 ways of getting the shop item slots, a static one:
```pascal
ShowOnTarget(Shop.SlotBoxes);
```


And a dynamic one:
```pascal
ShowOnTarget(Shop.FindItemBoundaries());
```

There are use cases for both, internally, `Shop.FindItemBoundaries` is usually used.



- - -

## Shop.SetupInterface
```pascal
procedure TRSShop.SetupInterface();
```
Internal method used to setup the {ref}`TRSShop` coordinates.
This is automatically called for you on the {ref}`Shop variable`.


- - -

## Shop.IsOpen
```pascal
function TRSShop.IsOpen(): Boolean;
```
Returns true if the shop interface is open.

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


- - -

## Shop.WaitOpen
```pascal
function TRSShop.WaitOpen(time: Integer = 600; interval: Integer = -1): Boolean;
```
Returns true if the shop opens within `time` milliseconds.

Example:
```pascal
WriteLn Shop.WaitOpen();
```


- - -

## Shop.Close
```pascal
function TRSShop.Close(escape: Boolean): Boolean;
function TRSShop.Close(escapeProbability: Double = BioHash): Boolean; overload;
```
Closes the {ref}`Shop` interface, depending on `escape` the function will either
press escape or click the close button.

Example:
```pascal
WriteLn Shop.Close();
```


- - -

## Shop.Buy
```pascal
function TRSShop.Buy(item: TRSItem; quantity: ERSShopQuantity = ERSShopQuantity.ONE): Boolean;
```
Attempts to buy the specified item from the shop.
With the proper quantity button enabled.

Example:
```pascal
WriteLn Shop.Buy('Gold ore', ERSShopQuantity.FIFTY);
```


- - -

## Shop.Sell
```pascal
function TRSShop.Sell(item: TRSItem; quantity: ERSShopQuantity = ERSShopQuantity.ONE): Boolean;
```
Attempts to sell the specified item to the shop from your inventory.
With the proper quantity button enabled.

Example:
```pascal
WriteLn Shop.Sell('Bones', ERSShopQuantity.FIVE);
```


- - -

## Shop.GetPrice
```pascal
function TRSShop.GetPrice(item: TRSItem): Integer;
```
Returns the price of an item in the shop by examining it.

Example:
```pascal
WriteLn Shop.GetPrice('Gold ore');
```


- - -

## Shop.SetQuantity
```pascal
function TRSShop.SetQuantity(quantity: ERSShopQuantity): Boolean;
```
Sets the shop quantity button (1, 5, 10, or 50).

Example:
```pascal
WriteLn Shop.SetQuantity(ERSShopQuantity.TEN);
```


- - -

## Shop.Hover
```pascal
function TRSShop.Hover(obj: TRSObject; walk: Boolean = True): Boolean;
function TRSShop.Hover(npc: TRSEntity; walk: Boolean = True): Boolean; overload;
```
This assumes that {ref}`Map` is being used and setup.
It's possible to use this with other systems but you need to configure it all
manually.

If you are too far, it will attempt to walk closer to it.


- - -

## Shop.Open
```pascal
function TRSShop.Open(obj: TRSObject; walk: Boolean = True): Boolean;
function TRSShop.Open(npc: TRSEntity; walk: Boolean = True): Boolean; overload;
```
Opens the shop for you.
This assumes that {ref}`Map` is being used and setup.

Example:
```pascal
{$I WaspLib/osrs.simba}
begin
  Map.Setup([Map.Setup([ERSChunk.BLAST_FURNACE]));
  Shop.Open(TRSEntity.Create(NPCsJSON.GetByName('Ordan', 1).Item[0]));
end.
```

## Shop variable
Global {ref}`TRSShop` variable.
