3D Drag Detector Permission Handling

I am trying to set the permission policy of a 3d Drag detector to a team however upon changing teams it knows that I’ve changed but it wouldn’t allow me to actually drag the physical object after it

local REQUIRED_TEAM = "TeamA"

local ScriptableFolder = workspace:WaitForChild("Scriptable")
local SpotLightFolder = ScriptableFolder:WaitForChild("WatchTower_SpotLights")


local function setupDragDetector(detector)
	if not detector:IsA("DragDetector") then return end

	local mainPart = detector.Parent

	local Players = game:GetService("Players")
	local localPlayer = Players.LocalPlayer

	detector:SetPermissionPolicyFunction(function(player)
		local teamName = player.Team and player.Team.Name

		if teamName == REQUIRED_TEAM then
			return true
		end

		return false
	end)
end

for _, obj in ipairs(SpotLightFolder:GetDescendants()) do
	setupDragDetector(obj)
end

SpotLightFolder.DescendantAdded:Connect(setupDragDetector)

Everything looks correct. I would try printing out teamName.

Perhaps your team has an invalid brickcolor or something so player.Team is nil?

I’m not very familiar with drag detectors, so perhaps the permission policy needs to be set on the server (this isn’t documented though).

Yes, thank you. The permission policy was needed to be set on the server then you pass the team name through an event from the client to the server to update it. I’ve put the scripts below just in case someone else runs into the same issue as me.

local

local Players = game:GetService("Players")
local localPlayer = Players.LocalPlayer
local replicatedStorage = game:GetService("ReplicatedStorage")
local updatePermissionEvent = replicatedStorage:WaitForChild("UpdatePermissions")

local function onTeamChange(newTeam)
	if not newTeam then return end

	if newTeam.Name == "TeamA" then
		print("Allowed — notifying server to update permissions.")
		updatePermissionEvent:FireServer(newTeam)
	else
		print("Not allowed.")
		updatePermissionEvent:FireServer(newTeam)
	end
end

if localPlayer.Team then
	onTeamChange(localPlayer.Team)
end

localPlayer:GetPropertyChangedSignal("Team"):Connect(function()
	print(localPlayer.Team)
	onTeamChange(localPlayer.Team)
end)

Server

local replicatedStorage = game:GetService("ReplicatedStorage")
local updatePermissionEvent = replicatedStorage:WaitForChild("UpdatePermissions")

local ScriptableFolder = workspace:WaitForChild("Scriptable")
local SpotLightFolder = ScriptableFolder:WaitForChild("WatchTower_SpotLights")

local function setupDragDetector(detector, team)
	if not detector:IsA("DragDetector") then
		return
	end

	detector:SetPermissionPolicyFunction(function(player)
		print("Checking team:", team)

		if team.Name == "TeamA" then
			print("Allowed")
			return true
		end

		print("Denied")
		return false
	end)
end

local function updatePermissions(team)
	for _, obj in ipairs(SpotLightFolder:GetDescendants()) do
		setupDragDetector(obj, team)
	end
end

updatePermissionEvent.OnServerEvent:Connect(function(player, newteam)
	print("Received update permissions event: " .. newteam.Name)
	updatePermissions(newteam)
end)
