Raycasting Spread not working

[hopeshusbvnd (eee)]

1. What do you want to achieve? A raycast with a spread

2. What is the issue? the code I’ve written doesn’t seem to add a spread like how I was expecting it to

3. What solutions have you tried so far? I’ve looked at a lot of posts and tried to use their solutions (but modified to fit my script) yet none of them have worked

here’s the raycast script i have

local CanaryRay = Ray.new(Character.Head.Position, (Character.Head.CFrame * CFrame.new(math.random(-4,4),math.random(-4,4),0)).LookVector * 20)

all help is appreciated

it helps if you could give more details. how do you expect the code to function, and how does it work at the moment? a picture or a video would help too.

even through i don’t know much of what you’re intending to do, i happen to have a spread function from another post, so perhaps you could try it:

--courtesy of: https://devforum.roblox.com/t/ideal-way-to-make-shotgun-spread/126567/7
function Vector_coneSpread(direction, maxSpread)
	local offsetRotation = CFrame.Angles(0,0,math.pi * 2 * math.random()) * CFrame.Angles(math.random() * math.rad(maxSpread),0,0)
	local offsetDir = (CFrame.new(Vector3.new(), direction) * offsetRotation).LookVector
	return offsetDir
end

Ideal way to make shotgun spread?

This is what I use for my shotgun spread. It gives a circular pattern, although it is more dense around the centre. This is an intended feature for mine, so most pellets go where you’re aiming, but you can mess around with it yourself. There are more efficient ways to calculate it, but I was just throwing it together and it’s not like this is running often lol. “dir” is the initial aiming vector, and “spread” is the maximum spread size in radians. local ang = CFrame.Angles(0,0,math.pi * 2 * m…

using the function (i’m more used to worldRoot:Raycast() instead of Ray.new() so i might not get it right):

local CanaryRay = Ray.new(Character.Head.Position, Vector_coneSpread(directionVector, maxSpread))

Yeah I probably should have, its a raycast that fires from the head of the character to about like 10-20 studs away and it stays contunious wether they turn or not. It’s for a sonic screaming ability and having it face just one direction instead of being spread out didn’t really work the way I wanted it to. Im gonna try your code and see if it works

According to this post Ray.new() is deprecated and you should use workspace:Raycast()

[jagenstien]

apparently tsering mentioned that Ray.new() is deprecated so here’s a version using worldRoot/workspace:Raycast():

local directionVector = (Target.HumanoidRootPart.Position - Character.Head.Position).Unit
local raycast = workspace:Raycast(Character.Head.Position, Vector_coneSpread(directionVector, maxSpread) * Range)

if raycast and raycast.Instance:IsDescendantOf(Target) then --check if the instance hit belongs to the target
	local Humanoid = Target:FindFirstChildOfClass("Humanoid")
	if Humanoid then
		Humanoid:TakeDamage()
	end
end
