# Currencies Manager

To use this system, inject ICurrenciesManager interface into your class, as shown below:

```csharp
[Inject] private ICurrenciesManager currenciesManager;
```

### Parameters in inspector

**currencies** – reference to serialized object which contains game currencies collection. By default, it refers to **Assets/Scriptables/Economics/CurrenciesCollection.asset**.

**saveAfterEachChange –** if true, currencies manager will automatically save currencies state after the each currencies amount change. Otherwise, you'll need to call SaveState method manually when you need.

### Available methods

```csharp
void AddCurrency(CurrencyType currencyType, int amount)
```

*This method adds a certain **amount** of currency of **currencyType** to player's in-game account. If **amount** is negative, currency will be withdrawn instead.*

*Examples:*

```csharp
currenciesManager.AddCurrency(CurrencyType.Soft, 100); //100 soft added
currenciesManager.AddCurrency(CurrencyType.Hard, -3); //3 hard withdrawn
```

***

```csharp
void SetCurrencyAmount(CurrencyType currencyType, int amount)
```

*This method sets a certain **amount** of currency.*

***

```csharp
void WithdrawCurrency(CurrencyType currencyType, int amount)
```

*This method withdraws **amount** of currency of **currencyType** from player's in-game account. If player doesn't have enough amount of this currency, it will be set to 0.*

```

***

```csharp
int GetCurrencyAmount(CurrencyType currencyType)

{
    //Player has enough hard currency to spend
    currenciesManager.WithdrawCurrency(CurrencyType.Hard, 3);
}
else
{
    //Player doesn't have enough hard currency
    uiController.ShowMessageBox("Warning", "Not enough money!");
}
```

***

```csharp
bool GetCurrencyInfo(CurrencyType currencyType, out CurrencyInfo currencyInfo)
```

*Example:*

```csharp
if (currenciesManager.GetCurrencyInfo(currencyType, out var info))
{
    currencyUISlot.SetData(info.Icon, currenciesManager.GetCurrencyAmount(currencyType));
}
