Create a 3rd vector based off the first 2

[Sckriptor]

I have two vector, X and Y. I want my 3rd vector, Z, to be offset by an arbitrary number that produces a vector that still aligns with X and Y.

I have tried X-Y or X+(X-Y).Unit, but i clearly dont know vector math like i thought i would.

Any help is appreciated

@Sckriptor

produces a vector that still aligns with X and Y

By this do you mean that if you draw a line between X and Y, the Z vector will fall somewhere on that line?

This can easily be done using linear interpolation (the :Lerp() method)

local X: Vector3 = Vector3.new(1, 2, 3)
local Y: Vector3 = Vector3.new(4, 5, 6)
local Z: Vector3 = X:Lerp(Y, math.random())

Oh my bad, i didnt mean a lerp. I want this 3rd point to EXCEED either the first or second. yet still be parallel.

IE XYZ or ZXY when you draw the line through them all

Then you can still use lerp for that. The alpha value just needs to be greater than 1 or less than 0.

I didnt know alpha can exceed or be less than 1. Ill brb to try this

EDIT: worked like a charm!
