Problems on hiding and showing arms when equipped and item and when unequipping and item?

I’m working on a game! I am trying to make it so that when you equip it shows your arms and vice versa.
The problem is there is not negative output in Roblox Studio and I can’t figure it out, I tried multiple ways to fix it but it is still the same.
Here is my script:

local character = player.Character or player.CharacterAdded:Wait()

local function ShowArms()
   game:GetService("RunService").RenderStepped:Connect(function()
   	for i, part in pairs (character:GetChildren()) do
   		if string.match (part.Name,"Right Arm") or string.match (part.Name, "Left Arm") then 
   			part.LocalTransparencyModifier = 0
   		end
   	end
   end)
end

local function HideArms()
   game:GetService("RunService").RenderStepped:Connect(function()
   	for i, part in pairs (character:GetChildren()) do
   		if string.match (part.Name,"Right Arm") or string.match (part.Name, "Left Arm") then 
   			part.LocalTransparencyModifier = 1
   		end
   	end
   end)
end

while true do
   task.wait()
   
   player.ChildAdded:Connect(function(item)
   	if item:IsA("Tool") then
   		HideArms()
   		print("HideArms succesfully")
   	else
   		player.ChildRemoved:Connect(function()
   			ShowArms()
   			print("ShowArms succesfully")
   		end)
   	end
   end)
end

Should be working now, hope it could help you!


local function ShowArms()
	
		for i, part in pairs (character:GetChildren()) do
			if string.find (part.Name,"Hand") or string.find (part.Name,"Arm") then 
				part.LocalTransparencyModifier = 0
			end
		end

end

local function HideArms()

		for i, part in pairs (character:GetChildren()) do
			if string.find (part.Name,"Hand") or string.find (part.Name,"Arm") then 
				part.LocalTransparencyModifier = 1
			end
		end

end




	character.ChildAdded:Connect(function(item)
		if item:IsA("Tool") then
			HideArms()
			print("HideArms succesfully")
		
		
	end
end)

		character.ChildRemoved:Connect(function(item)
			if item:IsA("Tool") then
				ShowArms()
				print("ShowArms succesfully")
			
		end
		
	end)

Maybe it’s because you’re trying to connect the ChildAdded and ChildRemoved events inside a while loop which could be causing multiple connections to be made every time the loop iterates.
Try this and let me know if it works>

local character = player.Character or player.CharacterAdded:Wait()

local function ShowArms()
   for i, part in pairs (character:GetChildren()) do
      if string.match (part.Name,"Right Arm") or string.match (part.Name, "Left Arm") then 
         part.LocalTransparencyModifier = 0
      end
   end
end

local function HideArms()
   for i, part in pairs (character:GetChildren()) do
      if string.match (part.Name,"Right Arm") or string.match (part.Name, "Left Arm") then 
         part.LocalTransparencyModifier = 1
      end
   end
end

player.ChildAdded:Connect(function(item)
   if item:IsA("Tool") then
      HideArms()
      print("HideArms successfully")
   end
end)

player.ChildRemoved:Connect(function(item)
   if item:IsA("Tool") then
      ShowArms()
      print("ShowArms successfully")
   end
end)

Thank you guys for the help but is there a reason why the hands are not showing when I’m equipping something it prints out successfully but I don’t apparently see my arms ? (btw the game is first-person lock)

The CharacterAdded event is fired before the character’s parts (like the arms) are loaded into the game. So when you call player.Character or player.CharacterAdded:Wait(), the character’s parts may not exist yet, causing your ShowArms and HideArms functions to not work as expected.

To fix this, you could use the ChildAdded event of the character to wait for the arms to be added

Try this,

local function ShowArms(character)
   for i, part in pairs (character:GetChildren()) do
      if string.match (part.Name,"Right Arm") or string.match (part.Name, "Left Arm") then 
         part.LocalTransparencyModifier = 0
      end
   end
end

local function HideArms(character)
   for i, part in pairs (character:GetChildren()) do
      if string.match (part.Name,"Right Arm") or string.match (part.Name, "Left Arm") then 
         part.LocalTransparencyModifier = 1
      end
   end
end

local function onCharacterAdded(character)
    character.ChildAdded:Connect(function(child)
        if child.Name == "Right Arm" or child.Name == "Left Arm" then
            if #character:GetChildren("Tool") > 0 then
                HideArms(character)
            else
                ShowArms(character)
            end
        end
    end)
end

player.CharacterAdded:Connect(onCharacterAdded)
if player.Character then onCharacterAdded(player.Character) end

player.ChildAdded:Connect(function(item)
   if item:IsA("Tool") then
      HideArms(player.Character)
      print("HideArms successfully")
   end
end)

player.ChildRemoved:Connect(function(item)
   if item:IsA("Tool") then
      ShowArms(player.Character)
      print("ShowArms successfully")
   end
end)

The script doesn’t work because I think the problem is the local functions I made HideArms() and ShowArms(), I tried your script but it still doesn’t work. I placed the script at StarterGui?

I forgot to tell that you shouldn’t have the “childadded” at the player but instead the character, try tweaking the codes sent here

Can anybody help me ? I need to develop my game quickly, I’m still stuck with the problem.

I have an alternative but it’s a bit complicated.
You can clone the arms and the humanoid and put it in a seprate model, the arms copy the position of the actual arms in renderstepped, and the unequip and equip you can just use transparency for it
