loading screen

[buoyant kestrel]

i've been trying to optimize my loading screen for a while, but i kept on getting a lag spike when destroying it (or setting it's parent to nil)

local function fade_gui_out()
    leave.Active = false
    
    --LAGFGG GSPIKE END IT
    local clok = os.clock()
    for _, obj in gui:GetDescendants() do
        if obj:IsA("TextLabel") or obj:IsA("TextButton") then
            TweenService:Create(obj, tinfo, {TextTransparency = 1}):Play()
            
        elseif obj:IsA("ImageLabel") or obj:IsA("ImageButton") then
            TweenService:Create(obj, tinfo, {ImageTransparency = 1}):Play()
            
        elseif obj:IsA("Frame") then
            TweenService:Create(obj, tinfo, {BackgroundTransparency = 1}):Play()
            
        end
    end
    
    warn("1: ", tostring(os.clock() - clok))
    task.wait(tinfo_duration + 0.2)
    
    RunService.PostSimulation:Wait()
    gui.Enabled = false
    
    RunService.PostSimulation:Wait()
    gui.Parent = nil
    
    RunService.PostSimulation:Wait()
    gui:Destroy()
    
    print("ok u can stop")
end```

the code i sent is currently using runservice.postsimulation because i kept alternating between task.wait, runservice.prerender and other stuff i thought would help not spike it

commenting out both the .parent = nil line and the :destroy one will solve the spike

btw the for loop doesn't cause any spikes whatsoever and it isn't an external script causing this; the warn() printed 1: 0.00007920000643935055

let me summarize this first

can you show me the loading screen UI so i can know more

[buoyant kestrel]

ya sure

screenshare? it's animated

[buoyant kestrel]

by code

[solemn sedge]

am not too good at scripting and UI but let me summarize by using my stupad kid ahh brain

[buoyant kestrel]

actually no, i'll just record and crop the part where it spikes

[solemn sedge]

ok

[solemn sedge]

hmmmm

what are you trying to fix btw

[buoyant kestrel]

wow

the lag spike

[solemn sedge]

oh yeah i forgot to see it :Skull:

hang on let me go seeing the issue (lag spike of the UI when clicking or the moving thing but let me see first)

oh i can see

the output

this might take a while to let me see the issue

[tall geyser]

make it a server script

[solemn sedge]

well so this kind of you need to use a CanvasGroup

you can control it the transparency for the entire group with group transparency

but if using a canvasgroup

its like uhh not really fixing the issue

you can put a local script inside the UI

if you cant use a canvsgroup

[buoyant kestrel]

you can control the transparency of the entire gui object using the canvas group instance?

[loud trench]

try allat without the postsimulation:wait

[buoyant kestrel]

still spikes

but

i found out that it only spikes in studio

not in the actual game

[solemn sedge]

so thats the first good thing

but are you trying to fix the lag spike in studio and also the actual ame

[dusty spear]

yes

it boosts performance by 100x

[buoyant kestrel]

i thought it'd spike in the game too

and also i dont think the canvas group would work

for avoiding the getdescendants loop

[solemn sedge]

yeah so thats why i said canvasgroup dont really work

[buoyant kestrel]

holy shit

canvas group is revolutionary

ill use that instead of looping through the descendants

thank you very very very much

saved me 0.007s and prolly a lot of memory

[solemn sedge]

uh yeah i use that a lot in a lot of UIS

** You are now Level 6! **

[solemn sedge]

but i dont think it works for a loading screen

its the problem solved?

[buoyant kestrel]

yes

[buoyant kestrel]

it works for all sorts of stuff

[wheat tangle]

man microprofiler exists tho

and

s2?

[buoyant kestrel]

i cant use it

[wheat tangle]

oh

[buoyant kestrel]

ive never had to use it

[wheat tangle]

wait why?

[solemn sedge]

not everyone use microprofiler

[buoyant kestrel]

and therefore didnt familiarize myself with it

i tried to

no spikes were showing up though

-# no spikes on ANY profiler service / thing

[wheat tangle]

have u tried benching it

see what takes too long

oh the problem is fixed

mb

[buoyant kestrel]

how

[wheat tangle]

;-;

[solemn sedge]

how

[solemn sedge]

wanna add me

[buoyant kestrel]

um

will this friendship benefit me

[solemn sedge]

idk man

why i have this in mind

[rough totem]

this happens when u destroy a script on studio i think

same thing happended to me

u get a lag spike

[buoyant kestrel]

this would actually explain so many things

i've just closed studio 'cause i need to go, i'll try it out tomorrow

thanks for the tip
