How can I make this raycasting gun less laggy?
My raycasting gun bounces off walls, but I don't think that is causing lag, because when I shoot it into the sky, it still lags. If you want the script that explains how you can make bullets bounce of walls that I used, go to this website. I edited the code to this for a gun. Local Script:
local mouse = game:GetService('Players').LocalPlayer:GetMouse()
local held = false
local equipped = false
local handle = script.Parent.Parent.Handle
local content = game:GetService('ContentProvider')
content:Preload('rbxassetid://171140306') --Equipping sound
content:Preload('rbxassetid://143286342') --Firing sound
content:Preload('rbxassetid://169310310') --Uneqipping sound
script.Parent.Parent.Equipped:Connect(function()
equipped = true
handle.EquipSound:Play()
end)
script.Parent.Parent.Unequipped:Connect(function()
equipped = false
handle.UnequipSound:Play()
end)
mouse.Button1Down:Connect(function()
if equipped then
repeat
wait(.18)
print('Fire!')
script.Parent.RemoteEvent:FireServer()
handle.FireSound:Play()
until not held or not equipped
end
end)
mouse.Button1Up:Connect(function()
held = false
end)
I used a RemoteEvent to fire the gun quicker.
ServerScript:
script.Parent:WaitForChild('RemoteEvent').OnServerEvent:connect(function()
local laser = Instance.new("Part")
laser.Name = "Laser"
laser.FormFactor = Enum.FormFactor.Custom
laser.TopSurface, laser.BottomSurface = 0, 0
laser.Size = Vector3.new(0.2, 0.2, 0.2)
laser.BrickColor = BrickColor.Random()
laser.Anchored = true
laser.CanCollide = false
laser.Locked = true
laser.CFrame = script.Parent.CFrame
laser.Parent = game.Workspace
local maxDistance = 400
local curDistance = 0
local stepDistance = 8
local stepWait = .2
local currentPos = script.Parent.Position
local currentNormal = script.Parent.CFrame.lookVector
local function Step(overrideDistance)
-- Cast ray:
local ray = Ray.new(currentPos, currentNormal * (overrideDistance or stepDistance))
local hit, pos, norm = game.Workspace:FindPartOnRayWithIgnoreList(ray, {script.Parent})
-- Update laser position:
laser.Size = Vector3.new(0.4, 0.4, (pos - currentPos).magnitude)
laser.CFrame = CFrame.new(currentPos:lerp(pos, 0.5), pos)
local oldPos = currentPos
currentPos = pos
if (hit) then
-- r = d - 2(d DOT n)n
-- Reflect:
local reflect = (currentNormal - (2 * currentNormal:Dot(norm) * norm))
currentNormal = reflect
Step(stepDistance - (pos - oldPos).magnitude)
return
end
curDistance = (curDistance + (pos - oldPos).magnitude)
-- Apply fade effect to laser as it approaches max distance from < 75 studs:
if (curDistance > (maxDistance - 75)) then
local d = (curDistance - (maxDistance - 75)) / 75
laser.Transparency = d
end
-- Recurse if max distance not reached:
if (curDistance < maxDistance) then
wait(stepWait)
Step()
end
end
Step()
-- Done! Destroy laser:
laser:Destroy()
end)
If you use this in a part, or ANYTHING, it will absolutely lag, even if you shoot it into the sky and only shoot one bullet.

I'm assuming you have Filtering Enabled, disabled so...
Update the laser's position client-side (if there were 10 players on the server and the server had to update lasers for all of them, that would cause lag).
If not...
You're gonna have to add a system where the client asks the server to create a part (making it global so everyone can see it) and then update its position by setting its current CFrame to whatever the laser's CFrame is.
You'll need to use RemoteEvents.
Example:
--Script called "RemoteServer" (or whatever) located in workspace
--Assuming the global ray has already been created
script.UpdateRay.OnServerEvent:connect(function(Player,Ray,NewCFrame)
Ray.CFrame = NewCFrame
end)
--LocalScript --Call this when you're updating the laser --Assuming that the global part has already been created game.workspace.RemoteServer.UpdateRay:InvokeServer(GlobalRay,laser.CFrame)
