You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? : Fix this error.

  2. What is the issue? It’s giving the error:

Workspace.Rocket Laucher Teste.Seat.Script:18: attempt to perform arithmetic (sub) on number and nil

  1. What solutions have you tried so far? I tried to instantiate the position given by the client

Script Server

local function lerp(p0,p1,t)
	return p0*(1-t) + p1*t --Error Line
end

		task.wait()
	end
	
end)

Script Client

mouse.Button1Up:Connect(function()
	if canShoot == true then
		canShoot = false
		local hit = mouse.Hit
		local hitPos = hit.Position
		fire:FireServer(hitPos)
		task.wait(2)
		canShoot = true
	end
end)

It’s my first topic, I don’t know if it will be good

#2

One of your arguments being sent to lerp doesn’t exist. Try printing each argument to debug which one doesn’t exist.

Actually, here’s your issue:

l2 = lerp(p1s.a2.Position,pos)

You’re calling lerp with 2 arguments, but 3 is needed or else it’ll throw an error.

#3

Yes, i forget t arg.
Thank You!
