- **Namespace:** MAP
- **Runtime name (Lua/JS):** `MapIsDiscoveryActive`
- **Side:** client (game native)
- **Name status:** community guess (may change)

## Signature

```c
BOOL _MAP_IS_DISCOVERY_ACTIVE(Hash discoveryHash);
```

## Parameters

- `discoveryHash` (`Hash`)

## Returns

`BOOL`

## Usage

### Lua

```lua
local retval = MapIsDiscoveryActive(discoveryHash)

-- always available, by hash
local retval = Citizen.InvokeNative(0x3F81EA4275D39D6F, discoveryHash, Citizen.ReturnResultAnyway())
```

### JavaScript

```js
const retval = MapIsDiscoveryActive(discoveryHash);

// by hash
const retval = Citizen.invokeNative('0x3F81EA4275D39D6F', discoveryHash, Citizen.returnResultAnyway());
```

### C#

```csharp
bool retval = Function.Call<bool>((Hash)0x3F81EA4275D39D6F, discoveryHash);
```

- Hash parameters: the named function also accepts a string and hashes it for you; `Citizen.InvokeNative` needs the number — pass `joaat("name")` or a backtick literal like `` `name` ``.
- The name is a community guess and may change. If the named call is missing in your client build, use `InvokeNative` with the hash — it always works.
