- **Namespace:** MISC
- **Runtime name (Lua/JS):** `GetAngleBetween_2dVectors`
- **Side:** client (game native)
- **Name status:** official
- **Documentation:** named only

## Signature

```c
float GET_ANGLE_BETWEEN_2D_VECTORS(float x1, float y1, float x2, float y2);
```

## Parameters

- `x1` (`float`)
- `y1` (`float`)
- `x2` (`float`)
- `y2` (`float`)

## Returns

`float`

## Usage

### Lua

```lua
local retval = GetAngleBetween_2dVectors(x1, y1, x2, y2)

-- always available, by hash
local retval = Citizen.InvokeNative(0xD0DFE1C486097BBB, x1, y1, x2, y2, Citizen.ResultAsFloat())
```

### JavaScript

```js
const retval = GetAngleBetween_2dVectors(x1, y1, x2, y2);

// by hash
const retval = Citizen.invokeNative('0xD0DFE1C486097BBB', x1 + 0.0000001, y1 + 0.0000001, x2 + 0.0000001, y2 + 0.0000001, Citizen.returnResultAnyway(), Citizen.resultAsFloat());
```

### C#

```csharp
float retval = Function.Call<float>((Hash)0xD0DFE1C486097BBB, x1, y1, x2, y2);
```

- 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.
