Signature

float GET_HEADING_FROM_VECTOR_2D(float dx, float dy);

Parameters

Name	Type	Description
`dx`	`float`	—
`dy`	`float`	—

Returns float

Description

dx = x1 - x2
dy = y1 - y2

Usage

Lua

local retval = GetHeadingFromVector_2d(dx, dy)

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

JavaScript and C#

JavaScript

const retval = GetHeadingFromVector_2d(dx, dy);

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

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.
