Unable to cast Instance to bool,what?
Why does it say this is it because of line 13 and it's loop?If so why and how do I fix it? Output:
22:51:16.693 - Unable to cast Instance to bool
22:51:16.694 - Script 'Workspace.Script', Line 12 - global MakeDisplayArms
22:51:16.694 - Script 'Workspace.Script', Line 28
22:51:16.695 - Stack End
22:51:16.695 - Disconnected event because of exception
game.Players.PlayerAdded:connect(function(Player)
Player.CharacterAdded:connect(function(Character)
---------------------------------------------------------
function MakeDisplayArms()
---------------------------------------------------------
local CurrentCamera = game.Workspace.CurrentCamera
local PlayerArms = {
Character["Right Arm"],
Character["Left Arm"]}
---------------------------------------------------------
for i,v in pairs (PlayerArms) do
FoundClonedArms = CurrentCamera:FindFirstChild("Cloned",v)--Finds for Cloned parts
if not FoundClonedArms then--Litte debounce
local ClonedArms = v:Clone()
ClonedArms.Parent = CurrentCamera--Hides it from everyone else
ClonedArms.Name = "Cloned",v--Renames it
ClonedArms.CanCollide = false
local Weld = Instance.new("Weld")
Weld.Part0 = v--Welds it Arms
Weld.Part1 = ClonedArms
return ClonedArms
else
return FoundClonedArms
end
end
end
---------------------------------------------------------
MakeDisplayArms()
end)
end)
What is this script suppose to do? This script is suppose to make a fake arm that is hidden in the CurrentCamera and that the player can see his arm when zoomed in.

The problem is EXACTLY what it says it is. The second argument to findFirstChild() is a BOOL value, v is an INSTANCE.
The CORRECT way to add strings together is by using ".."
Example
local MyString = "Hello " local player = "Player" local JoinedString = MyString .. player print(JoinedString) --> Hello Player
Your code would be
game.Players.PlayerAdded:connect(function(Player)
Player.CharacterAdded:connect(function(Character)
---------------------------------------------------------
function MakeDisplayArms()
---------------------------------------------------------
local CurrentCamera = game.Workspace.CurrentCamera
local PlayerArms = {
Character["Right Arm"],
Character["Left Arm"]}
---------------------------------------------------------
for i,v in pairs (PlayerArms) do -- IS V A OBJECT OR A STRING? IF IT IS AN OBJECT, I WOULD USE v.Name
FoundClonedArms = CurrentCamera:FindFirstChild("Cloned_" .. v)--Finds for Cloned parts
if not FoundClonedArms then--Litte debounce
local ClonedArms = v:Clone()
ClonedArms.Parent = CurrentCamera--Hides it from everyone else
ClonedArms.Name = "Cloned_" .. v--Renames it
ClonedArms.CanCollide = false
local Weld = Instance.new("Weld")
Weld.Part0 = v--Welds it Arms
Weld.Part1 = ClonedArms
return ClonedArms
else
return FoundClonedArms
end
end
end
---------------------------------------------------------
MakeDisplayArms()
end)
end)

I see you're trying to concatenate a string, try this.
game.Players.PlayerAdded:connect(function(Player)
Player.CharacterAdded:connect(function(Character)
---------------------------------------------------------
function MakeDisplayArms()
---------------------------------------------------------
local CurrentCamera = game.Workspace.CurrentCamera
local PlayerArms = {
Character["Right Arm"],
Character["Left Arm"]}
---------------------------------------------------------
for i,v in pairs (PlayerArms) do
FoundClonedArms = CurrentCamera:FindFirstChild("Cloned_"..v.Name)--Finds for Cloned parts
if not FoundClonedArms then--Litte debounce
local ClonedArms = v:Clone()
ClonedArms.Parent = CurrentCamera--Hides it from everyone else
ClonedArms.Name = "Cloned_"..v.Name --Renames it
ClonedArms.CanCollide = false
local Weld = Instance.new("Weld")
Weld.Part0 = v--Welds it Arms
Weld.Part1 = ClonedArms
return ClonedArms
else
return FoundClonedArms
end
end
end
---------------------------------------------------------
MakeDisplayArms()
end)
end)

I got a error saying attempt to concatenate local 'v' (a userdata value) kevinnight45 550 — 9y

Edited script, should work now. I tried to concatenate an instance, when I should've been concatenating a string, which is the name. Spongocardo 1991 — 9y
