🫡 Usage
-------

[](#-usage)

### 🚀 Installation

[](#-installation)

You can install the package via composer:

```
composer require nabeghe/levex
```

### Instance

[](#instance)

#### Default Instance

[](#default-instance)

Retrieve a singleton instance with default options:

```
use Nabeghe\Levex\Levex;

$levex = Levex::instance();
```

#### Custom Instance

[](#custom-instance)

Retrieve a custom instance with custom options:

```
use Nabeghe\Levex\Levex;

$options = ['baseLevelXp' => 50];
$levex = new Levex($options);
```

Options are related to class fields:

NameDescription`baseLevelXp`XP required to reach level 1. Default `100`.`levelLogBase`Logarithmic base in calculating the level by XP. Default `3`.`priceXpRate`XP rate per unit of price. For example, if the rate is 10, every 10 units of a specified price will equal 1 XP. Default `1`.`godLevelSymbols`Symbols that indicate a level associated with the creator or God, rather than a regular level. Default `['∞']`.`negativeLevelIsGod`Indicates whether a negative level should be considered as the god/creator or not. Default `true`.`levelNamesHandler`A callable that acts as a replacement for the determineLevelName method and takes the same input. If determineLevelName returns null, the main method will be executed. Used to customize the name/title of levels. Default `null`.---
