How do I point a Vector3 towards a location?

#1

I would like to give a starting position and an end position and create a Vector3 that will point to the end position from the starting position.

I’m not very good at vector math, and can’t figure it out

I have tried creating a CFrame that points to the location and getting it’s LookVector, however that A. didn’t point in the right direction and B. the Y value was huge for some reason

#2

A Vector3 does not have an orientation. If you mean that you would like to create a CFrame (which consists of both a translational and rotational component) centered at the starting position facing the target position, then the following snippet demonstrates a way to do this:

local eye = Vector3.new(0, 5, 0) -- starting position
local targetPosition = eye + Vector3.new(1, 1, 1) -- target position
local lookAtCFrame = CFrame.lookAt(eye, targetPosition)
#3

I mean like if I would like to create a Vector3 that if I moved a part along it starting at the start position it would move towards the end position

#4

Maybe something like this:

local directionVector = position2 - position1
print(position1 + directionVector) -- will return position2

I’m not really sure what you want.

#5

A vector does have a direction though(From an origin point). You can multiply vectors by integers which I believe is what partly linear interpolation is.

#6

It does have a direction and a magnitude, but when I said orientation, I was referring to the actual angular rotation in space.

#7

You can interpolate the start position to the end position with the “Lerp” method and then make your part face the end position using the lookAt constructor shown.

I believe you don’t actually need to make a CFrame you can just minus the originvector by the endvector which will make the endvector relative to the originvector and from there on you can lerp.

#9

You are correct, though I wasn’t too sure if they wanted the object to face its target as it was moving.

#10

To get the direction, just subtract them.
For example:

local startPos = Vector3.new(0, 1, 0)
local endPos = Vector3.new(0, 1, 5)
local direction = endPos - startPos
print(direction) -- prints 0, 0, 5

can’t believe i didn’t think of this lol

im not the best at math
