Client side projectile replication

Help and Feedback Scripting Support
1

I’ve decided that I want all my projectile logic on the client and just have the server deal damage. Here’s why:

As you can see the projectile has a noticeable delay when fired and then actually moving. Also, I don’t have a video of it, but the game gets pretty laggy when their are more players.

I have created a simple script, but I don’t know the best way to replicate the projectile for all the clients.

local script:

local UIS = game:GetService("UserInputService")
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local RE = game.ReplicatedStorage:WaitForChild("Magic")
local canuse = true
local character = player.Character
local debris = game:GetService("Debris")

UIS.InputBegan:Connect(function(key, chat)
	if key.KeyCode == Enum.KeyCode.E and not chat then

		local sound = Instance.new("Sound")
		sound.PlayOnRemove = true
		sound.Volume = 2
		sound.SoundId = "rbxassetid://144699494"

		local part = Instance.new("Part")
		part.Shape = Enum.PartType.Ball
		part.Size = Vector3.new(2,2,2)
		part.BrickColor = BrickColor.new("Bright red")
		part.TopSurface = Enum.SurfaceType.Smooth
		part.BottomSurface = Enum.SurfaceType.Smooth
		part.CanCollide = false
		part.CFrame = CFrame.new(character:FindFirstChild("HumanoidRootPart").Position, mouse.Hit.p)

		sound.Parent = part

		local bodyv = Instance.new("BodyVelocity")
		bodyv.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
		bodyv.Velocity = part.CFrame.LookVector * 100
		bodyv.Parent = part

		part.Parent = workspace.Projectiles

		part.Touched:Connect(function(touch) --I know touch events are bad but I couldn't think of a performant alternative (maybe raycasting or magnitude)
			if not touch:IsDescendantOf(character) then
				RE:FireServer(touch.Parent)
				part:Destroy() -- I know an exploiter could get rid of this but I dont know how to fix it

			end
		end)
	end
end)

Here is the Server:

local RE = game.ReplicatedStorage:WaitForChild("Magic")

RE.OnServerEvent:Connect(function(player, enemy)
	if player.character:FindFirstChildWhichIsA("Humanoid").Health > 0 and enemy:FindFirstChildWhichIsA("Humanoid") then
		enemy:FindFirstChildWhichIsA("Humanoid"):TakeDamage(35)
	end
end)

Now my question is, how do I allow it so all clients can see the projectile?

What games like Breaking point did is they set up a remote event which tells all clients the unit and mouse hit stuff.

e.g.

-- tell the server your stuff
game.ReplicatedStorage.dumbEvent:FireServer()

game.ReplicatedStorage.dumbEvent.OnClientEvent:Connect(function()
-- do things
end)

or you can have your server make the part (make sure the part is not anchored) and give the client network ownership or something along those lines

Maybe put the ball in replicated storage and call it from there instead of making a new instance. Not sure though.

Thanks for the reply. Could you go into a little more detail on the first one? Do you make two parts (one on the server and one on the client)?
