# Exports

#### Lowering a players permille by identifier

```lua
exports['jl_breathalyzer']:lowerPermille(permille, identifier)
```

**Updating a players permille by identifier**

```lua
exports['jl_breathalyzer']:UpdatePermille(permille, identifier)
```

#### Getting a players permille by source

```lua
exports['jl_breathalyzer']:GetPermille(source)
```

## Examples:

#### Here is an example of lowering a players permille by using a export above

```lua
function ConsumedItemForDecrease()
    if consumed then
        local permille = 1 -- This will lower the permille
        local identifier = QBCore.Functions.GetIdentifier(source, 'license') -- This will get the players license from source
        exports['jl_breathalyzer']:lowerPermille(permille, identifier)
    end
end
```

#### Here is an example of updating a players permille by using a export above

<pre class="language-lua"><code class="lang-lua"><strong>QBCore.Functions.CreateUseableItem("vodka", function(source, item)
</strong>    local Player = QBCore.Functions.GetPlayer(source)
    local permille = 0.2
    local identifier = QBCore.Functions.GetIdentifier(source, 'license')

	if Player.Functions.GetItemBySlot(item.slot) ~= nil then
        exports['jl_breathalyzer']:UpdatePermille(permille, identifier)
    end
end)
</code></pre>

#### Here is an example of getting a players permille by using a export above

```lua
RegisterCommand('getPlayerPermille', function()
    local src = source
    local permille = exports['jl_breathalyzer']:GetPermille(src)
    print(permille)
end)
```
