SetPartCollisionGroup is deprecated, please use BasePart.CollisionGroup instead

i managed to fix it,
i realised that i made the table called mob, and in the script i set the collision group to mobs

can you show the final script?

[Crypted_PlaysALT (skibidiohiogyatrizzy)]

local PhysicsService = game:GetService("PhysicsService")
local ServerStorage = game:GetService("ServerStorage")
local mob = {}


function mob.Move(mob, map)
	local humanoid = mob:WaitForChild("Humanoid")
	local waypoints = workspace.Waypoints

	for waypoint=1, #waypoints:GetChildren() do
		humanoid:MoveTo(waypoints[waypoint].Position)
		humanoid.MoveToFinished:Wait()
	end
	
	mob:Destroy()
	
end

function mob.Spawn(name, quantity, map)
	local mobExists = ServerStorage.Mobs:FindFirstChild(name)
	
	if mobExists  then
		for i=1, quantity do
			task.wait(0.5)
			local newMob = mobExists:Clone()
			newMob.Parent = map.Mob
			
			for i, object in ipairs(newMob:GetDescendants()) do
				if object:IsA("BasePart") then
					PhysicsService:CollisionGroupSetCollidable("Mob", "Mob", false)
					object.CollisionGroup = "Mob"

				end
			end
			
			coroutine.wrap(mob.Move)(newMob, map)
		end
		

	else
		warn("Mob could not be found!", name)
	end
end

return mob

change coroutine.wrap(mob.Move)(newMob, map) to task.spawn(mob.Move, newMob, map) because it is faster (at least from what i’ve heard)
