Lua Vector Bindings

The engine exposes Vector2, Vector3, and Vector4 types to Lua using sol2. These types are fully constructible in scripts and provide direct access to their components and common math properties.

---

Vector2

Construction

local v = Vector2()
local v = Vector2(x, y)

---

Fields

Name	Type
x	number
y	number

You can read and write these directly:

v.x = 10
v.y = 20

---

Properties

length

local len = v.length

Returns the magnitude of the vector.

---

lengthSquared

local len2 = v.lengthSquared

Returns squared length (faster than length).

---

normalized

local n = v.normalized

Returns a normalized copy of the vector.

---

Example

local v = Vector2(3, 4)

print(v.length)        -- 5
print(v.normalized.x)  -- 0.6

---

Vector3

Construction

local v = Vector3()
local v = Vector3(x, y, z)

---

Fields

Name	Type
x	number
y	number
z	number

---

Properties

length

local len = v.length

Returns magnitude of the vector.

---

lengthSquared

local len2 = v.lengthSquared

Returns squared magnitude.

---

normalized

local n = v.normalized

Returns a normalized copy.

---

Example

local forward = Vector3(0, 0, 1)
local dir = forward.normalized

---

Vector4

Construction

local v = Vector4()
local v = Vector4(x, y, z, w)

---

Fields

Name	Type
x	number
y	number
z	number
w	number

---

Notes

• Vector4 currently exposes only raw component access.
• No math properties (length/normalize) are bound yet.

---

Example

local color = Vector4(1, 0, 0, 1) -- RGBA
print(color.w)
