Vector2

Overview

Vector2 is a data type used to express vector in a two-dimensional space using X and Y axes. It is used to handle a variety of 2D data such as position, direction, speed, and strength. It is also one of the key elements used by many systems to calculate coordinates and vector within a space or simulating 2D physics.

Constructors

new

Creates and returns a new vector using the passed X and Y values.

Parameters

number x	The value of X coordinate.
number y	The value of Y coordinate.

Return

Vector2	The created Vector2.

Code Samples

local Vector = Vector2.new(3, 7)
print(Vector)

Properties

X

number

The value of X coordinate.

Code Samples

local Vector = Vector2.new(5, 10)
print(Vector.X)

Y

number

The value of Y coordinate.

Code Samples

local Vector = Vector2.new(5, 10)
print(Vector.Y)

zero

Vector2

A vector of which axis values are zeroes (0, 0).

Code Samples

local ZeroVector = Vector2.zero
print(ZeroVector)

one

Vector2

A vector of which axis values are ones (1, 1).

Code Samples

local OneVector = Vector2.one
print(OneVector)

xAxis

Vector2

A Vector2 set to have the value of 1 for X axis and 0 for Y axis (1, 0).

Code Samples

local XAxis = Vector2.xAxis
print(XAxis)

yAxis

Vector2

A Vector2 set to have the value of 0 for X axis and 1 for Y axis (0, 1).

Code Samples

local YAxis = Vector2.yAxis
print(YAxis)

Methods

Lerp

Calculates the linear interpolation between the current vector and the target vector according to alpha ratio and returns it as a new vector.

Parameters

Vector2 goal	The target Vector2 to be interpolated.
number alpha	A value indicating interpolation ratio.

Return

Vector2	The created Vector2.

Code Samples

local a = Vector2.new(0, 0)
local b = Vector2.new(10, 10)
print("Lerp:", a:Lerp(b, 0.3)) --> Output: 3, 3

Slerp

Calculates the spherical linear interpolation between the current vector and the target vector according to alpha ratio and returns it as a new vector.

While Lerp interpolates along a linear path, Slerp interpolates along a curve on a unit sphere, making its rotation axis movement smoother and more constant.

Parameters

Vector2 goal	The target Vector2 to be interpolated.
number alpha	A value indicating interpolation ratio.

Return

Vector2	The created Vector2.

Code Samples

local a = Vector2.new(1, 0)
local b = Vector2.new(0, 1)
print("Slerp:", a:Slerp(b, 0.5)) --> Output: 0.707107, 0.707107
