# Generating a random position 8 studs away from another

Im trying to do what the title says. I have a target position and what Im trying to do is generate a position 8 studs away from it in the x,z direction. So imagine a circle with a radius of 8 studs and I’m trying to get a random point on that circle.

local direction = CFrame.Angles(math.rad(math.random(0,90)), 0, math.rad(math.random(0,90)))|
clangorFight.Clangor.Humanoid:MoveTo(getGoalPosition() + direction*8)|

The error I’m getting from this is
invalid argument #2 (Vector3 expected, got number)

It seems like the error is from 0. It is expecting a vector 3 value with 3 numbers. You can make one like this:

Vector3.new(value1, value2, value3)

I’m not sure what 0 represents, but I think you must put a vector 3 value there instead.

Hope this helps.

You should be using :PivotTo() instead of :MoveTo()

:PivotTo will take a CFrame (which I see ‘direction’ is)
but when you do getGoalPosition() + direction, if getGoalPosition is returning a CFrame, you can’t add a CFrame + a CFrame, it wants the second value to get a Vector3

CFrame + Vector3 is what it needs, but I think you are doing CFrame + CFrame

getGoalPosition returns a vector3 value.

Doesnt it need vector3 + vector3? Thats what im trying to do because moveTo uses position

oh oh, lol, my bad, yeah, MoveTo, change your direction to direction.Position, to make it a vector3, because as is, direction is holding a cframe

try this

``````local startPosition = getGoalPosition()
local directionCFrame = CFrame.Angles(math.rad(math.random(0,90)),0,math.rad(math.random(0,90)))
local endPosition = startPosition + (directionCFrame.LookVector*8)
``````

if this is for a humanoid to walk to a position, you might be working with a flat surface, or floor, so maybe you are wanting to only rotate around the Y axis

such as

``````local directionCFrame = Frame.Angles(0,math.rad(math.random(0,90)),0)
``````

or something

Im getting half circle shapes, but on the wrong axis

I think you need to rotate on the Y, and not just 90, but try 360 for random angle.

it works

if you want to get the exact opposite spot on the circle, you can take do…

``````local oppositePosition = startPosition + (- directionCFrame.LookVector*8)
``````

take the negative of the lookVector, and multiply that by 8
