## Signature

```c
void SET_VEHICLE_WEAPON_HEADING(Vehicle vehicle, int seatIndex, float heading, BOOL p3);
```

## Parameters

- `vehicle` (`Vehicle`)
- `seatIndex` (`int`)
- `heading` (`float`)
- `p3` (`BOOL`)

## Returns

`void`

## Usage

### Lua

```lua
SetVehicleWeaponHeading(vehicle, seatIndex, heading, p3)

-- always available, by hash
Citizen.InvokeNative(0x194D877FC5597B7D, vehicle, seatIndex, heading, p3)
```

### JavaScript

```js
SetVehicleWeaponHeading(vehicle, seatIndex, heading, p3);

// by hash
Citizen.invokeNative('0x194D877FC5597B7D', vehicle, seatIndex, heading + 0.0000001, p3);
```

### C#

```csharp
Function.Call((Hash)0x194D877FC5597B7D, vehicle, seatIndex, heading, p3);
```

- 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.
