I have two Parts that serve as two different points for a region to be created: Shop_PointA and Shop_PointB. When the player steps inside of the region, the ScreenGui is enabled. I’m trying to detect when the player steps out of the region so I can disable the ScreenGui.
Here’s my entire code:
local Players = game:GetService("Players")
local shop_PointA = workspace.Shop_PointA.Position
local shop_PointB = workspace.Shop_PointB.Position
local touchedRegion = false
local shopRegion = Region3.new(
Vector3.new(
math.min(shop_PointA.X, shop_PointB.X),
math.min(shop_PointA.Y, shop_PointB.Y),
math.min(shop_PointA.Z, shop_PointB.Z)
),
Vector3.new(
math.max(shop_PointA.X, shop_PointB.X),
math.max(shop_PointA.Y, shop_PointB.Y),
math.max(shop_PointA.Z, shop_PointB.Z)
)
)
local ignoreList = {workspace.Shop_PointA,workspace.Shop_PointB}
while true do
wait(.25)
local partsInShopRegion = workspace:FindPartsInRegion3WithIgnoreList(shopRegion,ignoreList,math.huge)
local isEmpty = workspace:IsRegion3EmptyWithIgnoreList(shopRegion, ignoreList)
for _,v in pairs(partsInShopRegion) do
if isEmpty == true then -- This usually gets ignored, not sure what's happening
Players[v.Parent.Name].PlayerGui.UpdatesBrochure_UI.Enabled = false
else
if v.Parent:FindFirstChild("Humanoid")~= nil then
Players[v.Parent.Name].PlayerGui.UpdatesBrochure_UI.Enabled = true
end
end
end
end
I’ve also experienced some lag while testing this (most likely to do with the loop). What are some methods I can do to fend off those performance issues?
I’m still quite new to Region3, so first time I’ve attempted on this full-on. Maybe some imporvements?
So what i recommend you do to make this in the most efficient way is something like this:
(also sorry about the my formatting, i always make my code look the same lol)
local function toggleGUIWhenInRegion()
for _, plr in pairs(game:GetService("Players"):GetPlayers()) do
plr.PlayerGui.UpdatesBrochure_UI.Enabled = false -- disable it be default
end
local partsInRegion = workspace:FindPartsInRegion3WithIgnoreList(shopRegion, ignoreList, math.huge)
local plrDebounce = {} -- saves performance by only turning on the gui once, even if more than one part of their character is in the region
for _, v in pairs(partsInRegion) do
local model = v:FindFirstAncestorOfClass("Model")
local char = model and model:FindFirstChildOfClass("Humanoid")
local plr = char and game:GetService("Players"):GetPlayerFromCharacter(char)
if plr and not plrDebounce[plr.UserId] then
plrDebounce[plr.UserId] = true
plr.PlayerGui.UpdatesBrochure_UI.Enabled = true
end
end
end
while wait(0.25) do
toggleGUIWhenInRegion()
end
local partsInRegion = game.Workspace:FindPartsInRegion3(region3Test, nil, math.huge) -- get the possible players in the region --
local currentPlayers = {} -- a table for current players --
local oldPlayers = {} -- a table for older players --
while true do
oldPlayers = currentPlayers -- set the oldPlayers table to the LAST loop's
currentPlayers = {} -- clear the table before we work on it.
for _, part in pairs(partsInRegion3) do -- loop through the current parts in the region3
local player = game.Players:GetPlayerFromCharacter(part.Parent) -- get the player (or nil if it isn't a character)
if player then -- check if the player is nil --
currentPlayers[player.UserId] = player -- set the currentPlayers[userId] slot to the player object
-- enter code to do what you want on enter --
end
end
for _, player in pairs(oldPlayers) do -- loop through old players --
if currentPlayers[player.UserId] == nil then -- if this is true, they do not need to be prompted anymore
-- enter code to do what you want on exit --
end
end
wait(0.5) -- pretty demanding so don't make it update too much
end
I’ve tried it again and unfortunately it still doesn’t work.
This error is strange because I already have a ScreenGui created for the game beforehand and no script is tampering with in. I have also copied the name of my ScreenGui exactly so and pasted it into my script, yet it still errors…?
I’ve tried your solution but unfortunately it did not work towards my task. Though, I am curious, do you think that Magnitude would be better suited for this task?
I’ve been doing lots of research on Region3 through devforum posts and videos and honestly it just seems like I can never get it right.
I had the same problem. Try using that two-table method, and MAKE SURE TO SET THE PREVIOUS TABLE, AS WELL AS CLEAR IT. I had MAJOR issues with that when I was trying to learn Region3. Obviously, I can’t control what you do, but I’d recommend you just keep trying to make Region3s work.
local RegionPart = script.Parent
local Region = Region3.new(RegionPart.Position - (0.5 * RegionPart.Size), RegionPart.Position + (0.5 * RegionPart.Size))
RegionPart:Destroy()
local Watching = {}
while true do
wait()
Parts = workspace:FindPartsInRegion3WithIgnoreList(Region, {RegionPart}, math.huge)
for i,v in pairs(Parts) do
if v.Name ~= "HumanoidRootPart" then continue end
local Player = game.Players:GetPlayerFromCharacter(v.Parent)
if Player == nil then continue end
local Character = v.Parent
local Humanoid = Character["Humanoid"]
if Humanoid ~= nil then
Humanoid.MaxHealth = math.huge
Humanoid.Health = Humanoid.MaxHealth
end
if not table.find(Watching, v) then
Thread = coroutine.wrap(function()
table.insert(Watching, v)
while true do
wait()
local IsIn = workspace:FindPartsInRegion3WithWhiteList(Region, {v}, math.huge)
if #IsIn == 0 then
Humanoid.MaxHealth = 100
Humanoid.Health = 100
for x,c in pairs(Watching) do
if c == v then
table.remove(Watching, x)
end
end
coroutine.yield(Thread)
end
end
end)()
end
end
end
Modify my safezone script to give a gui instead of health?
local regionArea = workspace.TestRegion
local positionA = regionArea.Position - (regionArea.Size / 2)
local positionB = regionArea.Position + (regionArea.Size / 2)
local region = Region3.new(positionA,positionB)
local playerDebounce = {}
local player = game.Players.LocalPlayer
while true do wait()
local partsInRegion = workspace:FindPartsInRegion3(region, nil, math.huge)
local isInRegion = false
for i, v in pairs(partsInRegion) do
if game.Players:GetPlayerFromCharacter(v.Parent) == game.Players.LocalPlayer then
isInRegion = true
end
end
if isInRegion == true then
if not playerDebounce[player.UserId] then
script.Parent.Enabled = true
script.Parent.Frame.Position = UDim2.new(0.5,0,0,0)
script.Parent.Frame:TweenPosition(UDim2.new(0,0,0,0),Enum.EasingDirection.Out,Enum.EasingStyle.Sine,.15)
playerDebounce[player.UserId] = player
end
else
script.Parent.Frame.Position = UDim2.new(0,0,0,0)
script.Parent.Frame:TweenPosition(UDim2.new(0.5,0,0,0),Enum.EasingDirection.Out,Enum.EasingStyle.Quad,.1)
wait(.1)
script.Parent.Enabled = false
playerDebounce = {}
end
end
This code works perfectly – but my only concern is: can tables with lots of variables cause performance disruptions? Because if the player leaves while the Gui is on the screen, they’re still in the table… unless them leaving makes their own variable become nil? At any rate, let me know!
