Attempt to index local 'player'? I'm not sure to define the player in a regular function?
The error is on Line 16. "Attempt to index local 'player' (a nil value)" How would I define the player from a regular function. I tried putting the player in as a parameter but it didn't work.
Script in ServerScriptService Error on Line 16
leds = {}
function fade()
for i, v in pairs(leds) do
if v~= nil then
v.Transparency = v.Transparency + 0.2
if v.Transparency > 1 then
v:Destroy()
end
end
end
end
function makelig(player)
local b = player.Character:GetChildren()
for i = 1, #b do
if b[i].Name == "Left Arm" or b[i].Name == "Left Leg" or b[i].Name == "Right Arm" or b[i].Name == "Right Leg" then
local tip = b[i]
local lastpoint = b[i].Position
local tool = b[i]
if tip~= nil then
local off = tip.Size.z/2
local point = (tip.CFrame*CFrame.new(0, 0, -off)).p
local unit = (lastpoint - point).unit
local mag = (lastpoint - point).magnitude
if tool.Parent.Humanoid.WalkSpeed > 55 and mag>10 then
local middle = lastpoint-(unit*(mag/2))
local cf = CFrame.new(middle, point)
local l = Instance.new("Part")
l.Shape = tip.Shape
l.Name = "lightning"
l.Anchored = true
l.CanCollide = false
l.Size = Vector3.new(0.2, 0.2, mag)
l.BrickColor = BrickColor.new("Curry")

l.TopSurface = 0
l.Transparency = 0
l.BottomSurface = 0
l.Parent = tip

table.insert(leds, l)

end
end

Parameters and Arguments
I don't think you understand how parameters and arguments for functions work.
When you define a function with parameters(things inside the parenthasis) then you're making the function expect some kind of input.
Take this script for example:
function a(b)
print(b + 3)
end
a(2) --> 5
Notice the function was defined with the 'b' parameter - and that the parameter was then used inside the code.
'b' is a keyword to hold the first argument of input given by the function call. Notice on line 5 how the function was called with a '2'. In this situation, '2' is what 'b' is predefining.
Application
So, now lets apply this to your code. On line 15 you defined the 'makelig' function with a 'player' parameter. Then, on line 60 you called the function without suppying a 'player' argument. You need to call the function WITH arguments that correspond to the parameters you defined the function with.
makelig(player)
