# hasInterface

## Category
Multiplayer

## Arity
**Nular** — `hasInterface`.

```
hasInterface
```

## Description
Returns `true` if the current host has a player UI (graphical interface). Returns `false` for dedicated/headless servers. The host sets this via `HasInterface` property.

Registered by `DeclareMultiplayerCommands()`. **NOT called automatically** — host must invoke explicitly.

## How It Works
Reads the host's `HasInterface` flag. Controls whether UI-related code should execute.

## Usage

```sqf
if (hasInterface) then {
    // Initialize UI, HUD, menus
    createHUD();
    showIntro();
};

if (!hasInterface) then {
    // Headless — do server work only
    startHeadlessAI();
};
```
