How to disable collision for only Characters' Arms?

[DaMePlayzGames (MePlayzGames)]

I have a custom walk animation within my game, but is currently causing alot of problems for me because of how the Arms move. Is there anyway I can keep Character Collisions but disable the Collisions on the Arms? My game is in R6, thank you in advance

Yes you can.
I am pretty sure you can just turn off .CanCollide on each of your arm models.

This is actually from an open sourced script I found a while back. I modified it so that it only disables character-to-character collisions on the arms.

local PhysicsService = game:GetService("PhysicsService")
local Players = game:GetService("Players")
 
local playerCollisionGroupName = "Players"
PhysicsService:CreateCollisionGroup(playerCollisionGroupName)
PhysicsService:CollisionGroupSetCollidable(playerCollisionGroupName, playerCollisionGroupName, false)
 
local previousCollisionGroups = {}
 
local function setCollisionGroup(object)
  if object:IsA("BasePart") then
    previousCollisionGroups[object] = object.CollisionGroupId
    PhysicsService:SetPartCollisionGroup(object, playerCollisionGroupName)
  end
end
 
local function setCollisionGroupRecursive(object)
  setCollisionGroup(object)
 
	for _, child in ipairs(object:GetChildren()) do
		if child.Name == "Left Arm" or child.Name == "Right Arm" then
			setCollisionGroupRecursive(child)
		end
  end
end
 
local function resetCollisionGroup(object)
  local previousCollisionGroupId = previousCollisionGroups[object]
  if not previousCollisionGroupId then return end 
 
  local previousCollisionGroupName = PhysicsService:GetCollisionGroupName(previousCollisionGroupId)
  if not previousCollisionGroupName then return end
 
  PhysicsService:SetPartCollisionGroup(object, previousCollisionGroupName)
  previousCollisionGroups[object] = nil
end
 
local function onCharacterAdded(character)
  setCollisionGroupRecursive(character)
 
  character.DescendantAdded:Connect(setCollisionGroup)
  character.DescendantRemoving:Connect(resetCollisionGroup)
end
 
local function onPlayerAdded(player)
  player.CharacterAdded:Connect(onCharacterAdded)
end
 
Players.PlayerAdded:Connect(onPlayerAdded)

But, why???
can’t you just disable collisions on the arms.

That would disable all types of collisions on the arms, not just character-to-character interaction.

Yes thats the point.
Its supposed to do that.
