How do i prevent people from colliding eachother?

Help and Feedback Scripting Support

Hello developers!

I’m making a game but i know that they can climb to the top by climbing eachother.

My solution is making them non-collidable to eachother so they cant climb eachother! Easy!

But i don’t know how to script that so…

If someone has a solution please reply. Thank you.

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
    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)

Every script every developer uses, also make sure it is a script, you can put it in serverscriptservice or workspace
