Help with gun

[stray pilot]

So I'm making a gun that uses raycasting (like every other gun) and I want to add accuracy and idk how. I've tried adding a vector3 to the ray direction but it didn't work

thats probably why it didn't work

uhhh

then how do I do it if I can't add the vector3 😭

this is what i've tried

local Offset = Vector3.new(
math.random(-Accuracy, Accuracy),
math.random(-Accuracy, Accuracy),
math.random(-Accuracy, Accuracy)
)

local Params = RaycastParams.new()
Params.FilterType = Enum.RaycastFilterType.Exclude
Params.FilterDescendantsInstances = {Char, Gun}
local Direction = (Mouse.Hit.Position-Origin.Position).Unit
local FinalAim = (Direction+Offset).Unit
local RayCast = workspace:Raycast(Origin.Position, FinalAim*Range, Params)

what is value of accuracy

[stray pilot]

0.03

I've tried with higher values but didn't work either

and the Range is 500

do you have position and direction backwards?

[stray pilot]

huh

[plush gale]

do you have direction where the position should be and vica versa?

[stray pilot]

uhh no

[plush gale]

how do you know?

[stray pilot]

I don't 🙂

😨

well the technique looks fine, this is the naive way of doing bullet spread, not the best but it works y'know. if its not actually giving you accuracy setting then you probably did something else wrong, add prints to make sure its running etc

always read the docs https://create.roblox.com/docs/reference/engine/classes/WorldRoot#Raycast

yeah I did that before and the FinalAim gives a value near to 0 for some reason and when I add the range it gives the actual position

so it might be the way I make the bullet visible? idk

[plush gale]

the direction vector is not a position

the "value near to 0" is in reality a unit vector which is where the value of all 3 axis add to exactly 1

A unit vector is often used to represent directions, such as normal directions.
