Spread raycast (shotgun)

Help and Feedback Scripting Support
#1

hello. i am trying to transform this gun script into a shotgun script.

	local camera = game.Workspace.CurrentCamera

	local raycastParams = RaycastParams.new()
	raycastParams.FilterType = Enum.RaycastFilterType.Exclude
	raycastParams.FilterDescendantsInstances = {script.Parent.Parent} -- get rid of player

	local middleRay = camera:ViewportPointToRay(camera.ViewportSize.X/2, camera.ViewportSize.Y/2)

	local raycastResult = workspace:Raycast(middleRay.Origin, middleRay.Direction * 1000, raycastParams)

	if raycastResult then
		local Hit = raycastResult.Instance
		print("Hit part: "..Hit.Name)
		REshoot:FireServer(Hit)
		else
		REshoot:FireServer(nil)
	end

Try this:

local rayDir = middleRay.Direction
local spread = 5 -- Some number in degrees
rayDir = (rayDir + CFrame.Angles(
    math.rad(math.random(-spread, spread)),
    math.rad(math.random(-spread, spread)),
    math.rad(math.random(-spread, spread))
).LookVector) * 1000

You can then use rayDir as the direction for the raycast.

one question… how do i have to send the info to the shoot script?

#4

my shoot script is a serverscript so i would have to pass all hits using the remoteevent. the serverscript has a debounce so i could not pass all at the same time.

#5

my shoot (serverscript) looks like this

local tool = script.Parent
local REshoot = tool:WaitForChild("REshoot")

local Debris = game:GetService("Debris")

local Handle = tool:WaitForChild("Handle")



--SETUP
script.AMMO_LEFT.Value = script.AMMO.Value

	script.Parent.Handle.Shot.PitchShiftSoundEffect.Octave = math.random(1.5,2)
	script.Parent.Handle.Shot:Play()
	script.Parent.Handle.flare.GUI.Enabled = true
	task.wait(0.1)
	script.Parent.Handle.flare.GUI.Enabled = false
end

function Refresh_Gui()
	script.Parent.Handle.AMMO_GUI.TEXT_LABEL.Text = ""..script.AMMO_LEFT.Value.."/"..script.AMMO.Value..""
end

function ADD_DEBRIS(WHAT, duration)
	game:GetService("Debris"):AddItem(WHAT, duration)

You make a loop for each shot you want to make with the shotgun. In the loop, add the script I made, and replace middleRay * 1000 with rayDir.

#7

Would you mind editing the script that I provided to make it work? I would then mark your answer as solution

#8 
local camera = game.Workspace.CurrentCamera

local raycastParams = RaycastParams.new()
raycastParams.FilterType = Enum.RaycastFilterType.Exclude
raycastParams.FilterDescendantsInstances = {script.Parent.Parent} -- get rid of player

local middleRay = camera:ViewportPointToRay(camera.ViewportSize.X/2, camera.ViewportSize.Y/2)

-- Shoots 10 bullets. You can change this to whatever you want.
for i = 1, 10 do
	local rayDir = middleRay.Direction
	local spread = 5 -- Some number in degrees
	rayDir = (rayDir + CFrame.Angles(
 		math.rad(math.random(-spread, spread)),
		math.rad(math.random(-spread, spread)),
		math.rad(math.random(-spread, spread))
	).LookVector) * 1000

	local raycastResult = workspace:Raycast(middleRay.Origin, rayDir, raycastParams)

	if raycastResult then
		local Hit = raycastResult.Instance
		print("Hit part: "..Hit.Name)
		REshoot:FireServer(Hit)
	else
		REshoot:FireServer(nil)
	end
end

You can create an array and for each raycast performed, insert its raycast result instance. Then you can fire the server a single time.

local hits =  {}
for i = 1, 10 do
	-- Use the raycasting code that Axominock wrote

	if raycastResult then
		local hitInstance = raycastResult.Instance
		table.insert(hits, hitInstance)
	end
end

REshoot:FireServer(hits)

But how I might suppose to implement that
