datumhue.math.vec2

Construct 2D vectors.

Fields 6

Field	Type	Access	Description
`ZERO`	Vec2	read-only	The zero vector `(0, 0)`.
`ONE`	Vec2	read-only	`(1, 1)`.
`X`	Vec2	read-only	The +X axis `(1, 0)`.
`Y`	Vec2	read-only	The +Y axis `(0, 1)`.
`NEG_X`	Vec2	read-only	The -X axis `(-1, 0)`.
`NEG_Y`	Vec2	read-only	The -Y axis `(0, -1)`.

function

datumhue.math.vec2.from_angle(radians: number) -> Vec2

Unit vector pointing at radians from the +X axis.

Example

print(datumhue.math.vec2.from_angle(0)) --> vec2(1.0, 0.0)
local up = datumhue.math.vec2.from_angle(math.pi / 2)
print(up.y) --> 1.0

function

datumhue.math.vec2.from_array(a: number[]) -> Vec2

Vec2 from a {x, y} array (the inverse of vec2:to_array).

Example

local v = datumhue.math.vec2.from_array({ 3, 4 })
print(v) --> vec2(3.0, 4.0)
