Vector - Starline Lua API

3D vector with math. Vector(x, y, z).

local v = Vector(1, 2, 3)
v.x, v.y, v.z         -- 1, 2, 3 (writable)

local u = v + Vector(0, 0, 5)
local w = v * 2
local d = (v - u):Length()

Fields

v.x, v.y, v.z
v.x = 100

Arithmetic


`v + u`	component-wise
`v - u`	component-wise
`v * s`, `s * v`	scale by number
`v / s`	divide by number
`-v`	negation
`v == u`	exact equality

Methods


`v:Length()`	euclidean length
`v:LengthSqr()`	squared length
`v:Distance(u)`	`(v - u):Length()`
`v:Dot(u)`	dot product
`v:Cross(u)`	cross product, new `Vector`
`v:Normalize()`	unit vector, new `Vector`; zero-length returns `Vector(0, 0, 0)`

QAngle

Euler angles: pitch, yaw, roll. QAngle(pitch, yaw, roll).

local a = QAngle(0, 90, 0)
a.pitch, a.yaw, a.roll   -- 0, 90, 0 (writable)

No arithmetic (angles don’t add cleanly outside specific contexts). Extract the fields if you need to do math on them.

Passing to entity fields

Anywhere entity.* writes a Vector or QAngle schema field, both the typed object and a plain table work:

pawn.m_vecOrigin = Vector(0, 0, 0)
pawn.m_vecOrigin = { x = 0, y = 0, z = 0 }

pawn.m_angEyeAngles = QAngle(0, 90, 0)
pawn.m_angEyeAngles = { pitch = 0, yaw = 90, roll = 0 }

Reads always return the typed object.
