vector3

Creates a new vector3 value.

In FiveM’s Lua runtime, vectors are real data types, just like numbers, bools and strings are. This means that type(vector3(1, 2, 3)) will return vector3. More about this in the Lua runtime manual.

Many existing natives such as GetEntityCoords and SetEntityCoords already have first class support for vector3 values. For example, GetEntityCoords returns a vector3, whereas SetEntityCoords accepts one, instead of using individual x, y, z values. See the second example below for a real world use of vector3, or read more about them in the Lua runtime manual and native functions manual.

Syntax

vector3 vector3(float x, float y, float z)

Required arguments

Examples

Basic vector3 functionality:

-- Basic vector with zero length:
vector3(0, 0, 0)

-- Vectors are a real data type:
local v = vector3(1, 2, 3)
print(type(v)) -- prints `vector3`

-- Vectors support equality operators:
local v1 = vector3(1, 2, 3)
local v2 = vector3(1, 2, 3)
local v3 = vector3(4, 5, 6)
print(v1 == v2) -- prints `true`
print(v1 == v3) -- prints `false`
print(v1 ~= v3) -- prints `true`

-- Arithmetic operations between vectors are supported:
local v = vector3(1, 2, 3)
print(v + 2) -- prints `vector3(3, 4, 5)`
print(v - 2) -- prints `vector3(-1, 0, 1)`
print(v * 2) -- prints `vector3(1, 4, 6)`
print(v / 2) -- prints `vector3(0.5, 1, 1.5)`

-- Or even with another vector:
local v1 = vector3(1, 2, 3)
local v2 = vector3(4, 5, 6)
print(v1 + v2) -- prints `vector3(5, 7, 9)`
print(v1 - v2) -- prints `vector3(-3, -3, -3)`
print(v1 * v2) -- prints `vector3(4, 10, 18)`
print(v1 / v2) -- prints `vector3(0.25, 0.4, 0.5)`

-- Vectors can be inverted:
local v = vector3(1, 2, 3)
print(-v) -- prints `vector3(-1, -2, -3)`

-- The length of the vector can be retrieved (pythagoras):
local v = vector3(1, 2, 3)
print(#v) -- prints `3.742`

-- Unpacking works:
local v = vector3(1, 2, 3)
local x, y, z = table.unpack(v)

-- To get the individual values from a vector:
local v = vector3(1, 2, 3)
print(v.x) -- prints `1`
print(v.y) -- prints `2`
print(v.z) -- prints `3`

-- Vectors support arbitrary swizzling:
local v = vector3(1, 2, 3)
print(v.yx)   -- prints `vector2(2, 1)`
print(v.zx)   -- prints `vector2(3, 1)`
print(v.xyx)  -- prints `vector3(1, 2, 1)`
print(v.yxyx) -- prints `vector4(2, 1, 2, 1)`
print(v.zxxy) -- prints `vector4(3, 1, 1, 2)`

Since many native functions already return and support vectors in Lua, you can do the following to push your vehicle forward 5 meters relative to its own axis:

-- Get your vehicle's current matrix.
local vehicle = GetVehiclePedIsIn(PlayerPedId())
local _, forwardVector, _, position = GetEntityMatrix(vehicle)

-- Multiply the vector by 5, and add it to the current position.
-- Since directional vectors should usually have a length of 1, this works great.
local newPosition = (forwardVector * 5) + position

-- Update the vehicle position.
SetEntityCoords(vehicle, newPosition)
