Passing a sin wave through a remote event without it being solved

Help and Feedback Scripting Support
#1

Hey, so, I would like to pass a sin wave without it being solved on server?

--Server script
local sin = math.sin(tick()*1)*0.11
remoteevent:FireClient(plr, sin)

--Client script
remoteevent.OnClientEvent:Connect(function(sin)
while task.wait() do
print(sin)
end
end)

Let’s say when we fire :FireClient, sin is 0.5.
When it passes on client, it keeps 0.5 on client.
I think this problem occurs because the server script passes 0.5 instead of

math.sin(tick()*1)*0.11

. Is there a way I can solve this problem?

send the values to the client, and let them evaluate on the client.

I don’t really get what do you mean. Can you explain it more?

Basically, the values you are trying to multiply on the server,
send them to the client using a remote event

then on a client script
where it recieves the info, do the math.sin function

What you are looking for is sending a function, however I don’t think you can send functions over events. If you only want this specific function you could just have this stored and, when prompted, calculate it.

-- Client
remoteevent.OnClientEvent:Connect(function(<possible variables>)
    remoteevent:FireServer(<your equation here>)
end)

-- Server
remoteevent:FireClient(plr, <possible variables>)
remoteevent.OnServerEvent:Connect(function(reply)
    if reply == <correct answer> then
        -- code for correct answer here
    else
        -- code for incorrect answer here
    end
end)

I don’t think you guys get what im trying to achieve, let me open it more.
I wanna do a fireball projectile moving like a sin value. But since i wanna do the movement on client, I use a remote event.

--Serverscript
	local function createFire(pos, sin, sinaxis)
		local FireBall = Assets:FindFirstChild("Fireball"):Clone()
		local FireBallMain = FireBall:FindFirstChild("Main")
		
		FireBall.Parent = workspace
		FireBallMain.Position = Monster.HumanoidRootPart.Position
		FireBall.Humanoid.Animator:LoadAnimation(script.Parent.Parent.Animation.Fireball):Play()
		
		for i, Plr in pairs(Players) do
			Lighting.AttackRemotes.Undertale.Toriel.FireBall:FireClient(Plr, FireBallMain, sin, sinaxis)
		end
		
	end
	
	createFire(nil, math.sin(tick()*1)*0.11, nil)

--Localscript
script.Parent:FindFirstChild("FireBall").OnClientEvent:Connect(function(FireBall, sin, sinaxis)
	print("AE")
	coroutine.resume(coroutine.create(function()
		local times = 0

		repeat
			times += 1
			FireBall.FireBallMain.Position += Vector3.new(0.2, 0, sin)
			task.wait()
		until times == 500

		FireBall:Destroy()
	end))
end)

When Im passing the sin formula to the client, it keeps being the same sin value instead of changing through time.

In

The parameter math.sin(tick()*1)*0.11 will evaluated to a number when the function is called. It is this number which is then eventually sent to the client.

There is no function running creating new numbers, hence why it stays the same.
There are many ways to solve this issue, the way @OceanTubez mentioned being the most intuitive.

Function values can’t be transmitted across the client-server boundary, perform the sine function on the client that is fired.
