## Signature

```c
int _GET_NUM_CARS_FROM_TRAIN_CONFIG(Hash trainConfig);
```

## Parameters

- `trainConfig` (`Hash`)

## Returns

`int`

## Description

Returns amount for CAN_REGISTER_MISSION_VEHICLES

## Usage

### Lua

```lua
local retval = GetNumCarsFromTrainConfig(trainConfig)

-- always available, by hash
local retval = Citizen.InvokeNative(0x635423D55CA84FC8, trainConfig, Citizen.ResultAsInteger())
```

### JavaScript

```js
const retval = GetNumCarsFromTrainConfig(trainConfig);

// by hash
const retval = Citizen.invokeNative('0x635423D55CA84FC8', trainConfig, Citizen.returnResultAnyway(), Citizen.resultAsInteger());
```

### C#

```csharp
int retval = Function.Call<int>((Hash)0x635423D55CA84FC8, trainConfig);
```

- 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.
