Help with raycasting from a specific angle

[volkan58341122]

I’ve been trying to improve my enemy AI for past few days, I’m working on a horror-obby game, where monsters detect players and then start chasing them, I have one problem that confuses me a lot

How I can raycast from a angle? I tried so many ways, using LookVector but it doesnt seem to be working

I want to raycast from an angle just like in this example picture I made to visualize what I’m talking about (red lines are raycast):

[metatablebased]

local numberOfRays = 20
local rayDistance = 20

local angleStep = 90 / (numberOfRays - 1)

local direction = humanoidRootPart.CFrame.LookVector
for i = 0, numberOfRays - 1 do
	local angle = -45 + (angleStep * i)
	local rotation = CFrame.Angles(0, math.rad(angle), 0)
	local rayDirection = (rotation * direction).Unit

	local rayOrigin = humanoidRootPart.Position + direction * 1.5

	local hit = workspace:Raycast(rayOrigin, rayDirection * rayDistance)

	if hit then
		print("Hit object: " .. hit.Instance.Name)
	else
		print("No hit")
	end
end

don’t forget to add raycastparams for the parts, otherwise they would be hitting each other

Thank you very much!! Is there any way on how can I visualize?

this is what i’ve used:

local function createRayPart(origin, direction)
    local rayPart = Instance.new("Part")
    rayPart.Size = Vector3.new(0.1, 0.1, rayDistance)
    rayPart.Anchored = true
    rayPart.CanCollide = false
    rayPart.Color = Color3.new(1, 0, 0)
    rayPart.Material = Enum.Material.Neon
    rayPart.CFrame = CFrame.new(origin + direction * (rayDistance / 2), origin + direction)
    rayPart.Parent = workspace
end

-- and in the for loop, just call it
createRayPart(rayOrigin, rayDirection)
