Attempt to index local 'mouse' (a nil value)???

So after i converted my local script and moved it to a normal script witch acts as a remote event for it(swiching game from non-fe to fe) I started getting this message:attempt to index local 'mouse' (a nil value) I don't know what is wrong. I whould apreciate if someone could look at the code and figure it out. Thanks in advance

script.Fire.OnServerEvent:Connect(function(Player)

local mouse = Player:GetMouse() local flame = game.Workspace.Amaterasu local db = false

local timeout = 20

db = true
while timeout > 0 do
local  flameCOPY = flame:Clone()
flameCOPY.Parent = game.Workspace
flameCOPY.CFrame = mouse.Hit
flameCOPY.Name = "Amaterasu2"

	timeout = timeout - 1
	wait(0.1)
 end
timeout = 20

end)

You cannot access the mouse from a server script so you need to split it into a local and server script.

In the local script you want to tell the server your mouse position, something like so:

local player = game:GetService("Players").LocalPlayer
local mouse = local Mouse = player:GetMouse()

yourFunction()
local firePosition =  mouse.Hit
Fire:FireServer(firePosition )
end

And in the server script you do the rest of the script

local player = game:GetService("Players").LocalPlayer
local mouse = local Mouse = player:GetMouse()

script.Fire.OnServerEvent:Connect(function(Player, firePosition)
local flame = game.Workspace.Amaterasu 
local db = false
local timeout = 20
db = true
while timeout > 0 do
local  flameCOPY = flame:Clone()
flameCOPY.Parent = game.Workspace
flameCOPY.CFrame = firePosition 
flameCOPY.Name = "Amaterasu2"

    timeout = timeout - 1
    wait(0.1)
 end
timeout = 20
end)

You should look at this wiki article for more info, there's a lot to learn about switching to F.E.

Thanks for that buti have one more question, in order for my script to work i need a "continous" mouse position update. The move is rapidly spawned where the user is moving their mouse. Any help on that?
