Why is cancollide working for me but not other players?

For some reason the collision groups work for me but not my friend.

Heres the Script:

local Players = game:GetService("Players")
local PhysicsService = game:GetService("PhysicsService")

Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(character)
		for i, object in ipairs(character:GetDescendants()) do
			if object:IsA("BasePart") then
				PhysicsService:SetPartCollisionGroup(object, "Player")
			end
		end
	end)
end)

You should look at this tutorial for a better way to set the collision group of whole characters. It is possible that a script in your game is causing this or something I can’t see, but this script should fix those issues.

This script is taken from Detecting Collisions | Roblox Creator Documentation . I’m not saying to copy the entire script unless you wish, but it shows some good practice.

local PhysicsService = game:GetService("PhysicsService")
local Players = game:GetService("Players")

local playerCollisionGroupName = "Player"

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
		setCollisionGroupRecursive(child)
	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)
