How would i send raycasts in a circle around certain position?

[TFlanigan (teef)]

for example lets say i want to send 8 rays evenly distributed around a certain position like this:

how would i calculate the direction of each ray?

What do you need to use this for?

i want to make a grenade launcher for my game that shoots bullets around the grenade when it hits something

This code here can help you a lot:

local PartShooting = script.Parent -- part that fires rays
local Degrees = -45

for i = 360, -360, Degrees do
	local Angle = i
	local Rotation = CFrame.Angles(math.rad(Angle), 0,0)
	local rayAngle = Ray.new(PartShooting.CFrame.Position, (PartShooting.CFrame * Rotation).lookVector * 20)
	local anglePart, position = workspace:FindPartOnRayWithIgnoreList(rayAngle, {PartShooting})

	-- Visualize the rays, not necessary, you can delete it
	local VisualRay = Instance.new("Part")
	local StartPos =  rayAngle.Origin
	local Endpos = StartPos + (rayAngle.Direction)
	local distance =  (StartPos - Endpos).Magnitude 
	VisualRay.Size = Vector3.new(0.3, 0.3, distance) 
	VisualRay.CFrame = CFrame.new( StartPos , Endpos) * CFrame.new(0, 0, -distance *.5)
	VisualRay.Anchored = true
	VisualRay.Parent = workspace
end
