🎮 Optimizing Game Performance with UI Raycast Target
In this video, the host introduces a simple tip to optimize game performance by disabling the raycast target option in non-integrated UI elements. The tutorial utilizes the Access Code GUI Pro kit and encourages viewers to check it out via a link in the description. The host demonstrates the impact of this optimization by running a game with a lot of UI elements stacked together. Initially, the game runs normally, but upon opening the profiler, it's revealed that the UI elements are causing a significant performance hit when the mouse is moved in and out of the window. The host explains that the raycast target is responsible for detecting UI interactions, but it's unnecessary for non-interactive elements. To illustrate the point, a script is introduced that can enable or disable the raycast target for all children of a UI element, saving time and improving performance. The host uses the Naughty Attributes package to streamline this process and invites viewers to check out a full tutorial for more information.
🔍 Enhancing Game Efficiency by Managing Raycast Targets
Continuing from the previous segment, the host demonstrates the benefits of disabling raycast targets in UI elements. Initially, with raycast targets enabled, the game's performance is noticeably impacted, as shown by the profiler. The host then uses a script to disable raycast targets in the UI, which significantly reduces the event system's processing time from 5.95 milliseconds to 1.47 milliseconds. This improvement is crucial for games where UI interactions are frequent. The host also highlights the importance of selectively disabling raycast targets, as doing so on interactive elements like buttons can prevent them from responding to clicks. The video concludes with a reminder to consider the impact of UI optimizations on game performance and encourages viewers to like, subscribe, and comment if they are interested in more optimization topics.

Transcripts
hi welcome to my Channel today I will
show you a simple tip to optimize your
game
I will go straight to the point that is
disable the raycast target option right
here
in all the non-integrated UI elements
why that's let's find out
in this tutorial I use the access code
GUI Pro kit cash again
I will give a link down in the
description below
if you're interested in it you can check
it out
and for the sample scene I have a lot of
UI
right here stack you on each other
the reason for that is I'm gonna show
you how significant as we gonna optimize
our game if we had a lot of UR now first
I will run the game
you will see that everything is quite
normal
but but I will open the value to show
you something
when I open the profiler please make
sure to enable the info file option
right here
this will help us to investigate all our
matters go to see how we can optimize
our code now let's run the game why
before 5.
you'll see the sky usual but let me show
you something I will move my browser
here
you see it has been searched
and when I move my mouse out the window
is gone
move in
it's went up move out it's gone move in
is well enough and move out it is gone
so something is quite unusual here let's
click it
you see
the play Loop half run for 28.6
milliseconds let's further investigating
it
and for you guys to know you can show us
how much time is going to run by
clicking right here and here I will
short form the top to bottom
and what we're gonna notice is you're
gonna click here
update the script run Behavior update
event system update click it standalones
input module process
kick it
process more event
now we see something quite unusual
remember
these search only happen when we move
the mouse in the window and it's gone
after we move value
so
there's something in here it says run
for
5.74 milliseconds
let's investigate more
you will see that it has supported input
module a small pointer event data
and now we see the coping it is the
event system and for sophisticated Easy
graphic raycaster that raycast
the reasons for that is when we're
interacting with the UI what we actually
do is we're gonna
create a request from our screen's
rotation I will call it X and Y and we
will create array cast and shooter
UI and Reddit found Target it will
notify the event system to let us know
that ah we interacting with our UI let's
give a response
however it is only model if we collide
with an interactive UI for example an
eut button because when we click the
button it will give us back the response
however in here if we interact with
non-interactive UI for example the image
right here it doesn't give us any
response so it is no point of doing that
and in next I will show you the data to
see that is disabled the request Target
actually model or not let's find out
accurate a civil script which has two
methods one is disable request and two
is enabling cast
what the message do is actually we're
going to Loop through all the children
if it's hardly it mesh component
I will be stable or enable it in here I
have the attribute called button and it
will allow us to execute our method in
the inspector it is from the naughty
attribute package and if you want to
learn more I have the full tutorial
right here I will give a link down in
the description below so make sure to
check it out now let's see it later in
the panels you will see that I have the
optimize raycast screen right here and
it has two buttons disable request and
enable request
first let's check
in the background you will see that I
had the request I guess enabled
when I click here
you will see that it's become disabled
oh that is still the same
so I don't have to manually go to all
the servants to click the button one by
one it's wasted time
use this package use naughty attribute
it's going to help us saving the
valuable time this weekend
now I will open the forefather to see
the major difference
click windows
analysis and profiler
remember to enable d45
now let's play
you will see that when relax our leg
break has started to be enabled
I will resign this a little bit I will
click here
you see that
something is quite searching here let's
click it and in play Loop you will find
update script run Behavior update click
here click here
click here
click here and you will see process mode
events
as it is where we click the button we
click the screen
let's further investigate
you will see that the event system
requires all take about
5.95 milliseconds
now
how about we disable all the records
Target
in the click panel
disable request
check again you'll see that the request
I guess has been set to disable let's
click here
you see that it's still searching but
when you click it
it's now gone to
1.47 milliseconds
remember in the real games especially in
some kind when you have to interact a
lot to your UI or some other games when
you have to tap a lot to draw to the
screen this will have a major impact on
your game and reduce how things run
foreign
thing you need to be taken into
consideration is as you can actually
disable raycast Target in your button
and it doesn't change anything
for example when I click button one it
will log out button won't have been
clicked and this was right here also
button and when I click it down it has
allow button to have been clicked and
for example in this button
which is right here I will put the
dual window for you have to see
there you go this is button and I can
just disable request Target
and for example when I click it
everything is still be fine however
in this thing
when I just disable
raycast Target
and when I click it
nothing will happen
but when I enable it
the enclosed message
has been printed out
the differences in here is as the source
image of this thing had no value
why is the button it has UI Sprite and
somehow
when the search image is low
you can just disable request Target and
expect the on click event between now
so you should be careful with that
is the ends of my video
if you like it please consider like And
subscribe to the channel this will be
really helpful to me if you interest in
some optimization topic
please comment down below
thank you for watching have a nice day
