# MISC::GET_HEADING_FROM_VECTOR_2D

- **Hash:** `0x38D5202FF9271C62`
- **Namespace:** MISC
- **Runtime name (Lua/JS):** `GetHeadingFromVector_2d`
- **Side:** client (game native)
- **Name status:** official
- **Documentation:** described
- **Since game build:** 1207
- **URL:** https://natives.borderlinerp.com/natives/MISC/GET_HEADING_FROM_VECTOR_2D

## Signature

```c
float GET_HEADING_FROM_VECTOR_2D(float dx, float dy);
```

## Parameters

- `dx` (`float`)
- `dy` (`float`)

## Returns

`float`

## Description

dx = x1 - x2
dy = y1 - y2

## Usage

### Lua

```lua
local retval = GetHeadingFromVector_2d(dx, dy)

-- always available, by hash
local retval = Citizen.InvokeNative(0x38D5202FF9271C62, dx, dy, Citizen.ResultAsFloat())
```

### JavaScript

```js
const retval = GetHeadingFromVector_2d(dx, dy);

// by hash
const retval = Citizen.invokeNative('0x38D5202FF9271C62', dx + 0.0000001, dy + 0.0000001, Citizen.returnResultAnyway(), Citizen.resultAsFloat());
```

### C#

```csharp
float retval = Function.Call<float>((Hash)0x38D5202FF9271C62, dx, dy);
```

- 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.
