## Signature

```c
void MODIFY_VEHICLE_TOP_SPEED(Vehicle vehicle, float value);
```

## Parameters

- `vehicle` (`Vehicle`)
- `value` (`float`)

## Returns

`void`

## Usage

### Lua

```lua
ModifyVehicleTopSpeed(vehicle, value)

-- always available, by hash
Citizen.InvokeNative(0x35AD938C74CACD6A, vehicle, value)
```

### JavaScript

```js
ModifyVehicleTopSpeed(vehicle, value);

// by hash
Citizen.invokeNative('0x35AD938C74CACD6A', vehicle, value + 0.0000001);
```

### C#

```csharp
Function.Call((Hash)0x35AD938C74CACD6A, vehicle, value);
```

- Float parameters: Lua integers (`10`, or whole numbers decoded from NUI/JSON) are sent as ints and read as garbage. Write `10.0` or `value + 0.0`. The generated JS wrappers add `0.0000001` to non-zero floats for the same reason.
