# Exports

CrossLab exposes a few exports so you can interact with it from other resources — useful if you want to open the menu through a different UI, sync crosshair settings with something else, or build on top of the system.

{% tabs %}
{% tab title="Client-side" %}
These are called from client scripts in another resource.

```lua
-- Open / close the crosshair menu
exports['s4-crosslab']:openMenu()
exports['s4-crosslab']:closeMenu()

-- Check if the menu is currently open
local open = exports['s4-crosslab']:isMenuOpen()  -- returns boolean

-- Get the current crosshair settings table
local settings = exports['s4-crosslab']:getCrosshairSettings()
```

The settings table returned by `getCrosshairSettings` is the same structure as `Config.DefaultCrosshair`:

```lua
{
    crosshairEnabled  = true,
    crosshairStyle    = 4,
    size              = 3,
    thickness         = 1,
    gap               = -3,
    fixedGap          = -25,
    csColor           = 1,
    colorR            = 46,
    colorG            = 250,
    colorB            = 46,
    alpha             = 200,
    useAlpha          = true,
    dotEnabled        = false,
    tStyleEnabled     = false,
    outlineEnabled    = false,
    outlineThickness  = 1,
}
```

{% endtab %}

{% tab title="Server-side" %}
These are called from server scripts in another resource.

```lua
-- Get the saved crosshair settings for a player (returns nil if not loaded yet)
local settings = exports['s4-crosslab']:getCrosshairSettings(source)

-- Overwrite a player's crosshair and sync it to their client immediately
local ok = exports['s4-crosslab']:setCrosshairSettings(source, {
    crosshairEnabled = true,
    crosshairStyle   = 2,
    size             = 4,
    -- etc.
})
```

`setCrosshairSettings` saves the data to the player's file and triggers a client sync right away. It returns `true` on success, `false` if you passed a nil data table.
{% endtab %}
{% endtabs %}

## Notes

* Settings are cached in memory on the server as soon as a player loads. `getCrosshairSettings` reads from that cache, not the file, so it's fast.
* If you call `setCrosshairSettings` before the player has fully loaded, the data will still be saved to file and applied next time they trigger `s4-crosslab:playerLoaded`.
