Optimizing Boat Attack for Mobile


I had previously developed a AAA quality game in 7 days(link), during its development I realised the 
importance of optimization and straight away from thereafter I have been studying about optimizing 
games especially in the Unity game engine.

I tried searching youtube about how to optimize games and tried many things on my game that doesn't 
resulted in something very good but I had idea as what to do and what not while optimizing a game.
That project finally broke and my machine wasn't able to bake lights for it or even run it at 10 fps.

I started with the Boat Attack to initially study URP and it's optimization and found out that even it is
not optimised for mobile, it ran at 13-15fps on my android which has SD 730.

From then on I started optimizing it and realised that the optimization is really shady field even to
the study, there are very limited videos but lot of documentation to read and the numerous hours of 
reading that only helped me.

Initially, I realised that Vulkan architecture was the problem and disabling it boosted the fps to 28-30.

I raised an issue on it's GitHub repo also: link

The profiler screenshot is given below:



I tried hundreds of things which I can't even remember, almost triggered every setting available inside
Unity from rendering URP settings to Build settings and finally I was able to achieve 50-52 fps on SD 730.

The final build optimised apk link is: here


Do watch how I made a game in 7 days video here(link).







Working with Unity's Shadergraph in URP 2019.3



I tried my hands on with the Unity's Shadergraph in Unity 2019.3 in Universal Render Pipeline.
I started off by creating a simple flag wave shader using Unity's learn live, then went on with exploring YouTube and creating more shaders and getting used to the shadergraph experience.

The major difficult thing was the URP, although it has shadergraph support but it lack features when compared to HDRP and that proglem was with almost every youtube video, although Brackeys were really good at this.

Most difficult shader was the ocean water one, that has to be created in URP but again had multiple problems like the depth node was most difficult one and now also I fear to use it, even I don't know but somehow after creating water for 2 days(that too following a tutorial) I had water, ha ha.
  
Visuals could have been better in HDRP but URP was the challenge and result is pretty good considering that this is capable of running on mobile.
*Everything was created inside Unity using ShaderGraph, only flag png was imported*
The scene has six shaders: Ocean water, Glow(on flag pole), Hologram, Disappearing, Flag wave & Cube neon tile.

Running on mobile was the best part and Ocean Water, the most difficult one, it took me 2 days to make water in URP, even now I can't understand many steps and nodes in ShaderGraph and why I used them.

The experience was good as ShaderGraph made it easier but still, I understood that Shaders is not my cup of tea, it's like stone pelting to my brain.

All thanks to Unity's Learn Live as it started with a flag wave shader and went on to this, also thanks to Brackeys, AE Tuts and PolyToots.

SpaceVR a journey beyond.




SpaceVR was my 2019’s 2nd ambitious VR (first one) project
which initially started as Moon exploration virtual reality app  
focussing on the lunar south pole to a space exploration VR 
app with a full business plan focussed on providing affordable 
VR education to masses for Indian schools.


It all started with NASA Space Apps regionals at my 

college KIIT, I had decided to make a Moon explorable

terrain in VR because I knew only VR in all of the 

problem statements that were given, with some research 

we(me and my team-mate Rahul) found out that 
something like this was already done previously in 
Space Apps Internationals but those represented Apollo 
Mission sites and here’s the catch that I got, why not 
make a moon explorable terrain that involved India’s 
Chandrayaan mission, it was trendy at that time as it 
was about to land on September 7, this hackathon was 
on 16-17 August as far as I remember. So we just did it, 
Rahul did the research part and I just quickly implemented 
the Lunar South Pole of Moon creating landing site of 
Vikram Lander with our lovely Pragyan rover created by 
Praddyum(he was in another team though ;)), he is our 
3D modeller. In 2 hours the prototype was complete and 
in approx 2 hours more, the results were announced and 
we had Won! Just like that, I wasn’t expecting as this was 
my first Hackathon but luck was on our side though.

We qualified for Nationals of Space Apps to be held at 
Delhi and later we came to know the date, it was 18-21 
October 2019 and so we started again, the problem 
statements were out and there was no Moon problem 
statement, so we had to make again from scratch and 
this time I did some real sweating work and Rahul, 
some real research as we had to plan a journey to 
Kuiper belt that should be scientifically accurate in 2045, 
Yes! We had taken some assumptions -3 assumptions to 
be specific. Rahul planned out the journey and I did the 
implementation part, it was during the Durga Puja and so 
I had the time and I seriously used it. During the 36 hour 
hackathon, we had made the full journey that would 
start from Earth and take you to International Space Station 
which had some real no gravity effect and was exact replica 
of the real one, from ISS you are headed towards Kuiper belt 
objects namely Pluto, Makemake and Haumea, if you are 
wondering what are those weird names, they are just names 
of planets with some special behaviour, I mean absurd behaviour.
We could just tell one thing that the quality 
we had made, the graphics was at par for the mobile platform 
but still we LOST! as it lacked innovation and yes it lacked!


The hackathon was over but SpaceVR was still on and so this time 
we took it for a B-Plan in KIIT-Fest in December and lost again but 
as it is said that there is always gaining and so we now had a real 
business plan for our SpaceVR that could be presented.

We expanded the project more and this time we designed complex 
scientific phenomenons in VR, like gravitational waves, spacetime 
wells, accretion disc, gravitational phenomenon, planetary movements. 
We were making this because our app was moving forward as per our
 business plan that was to make educational content in VR, generally, 
such type of education is considered for elementary schools only, 
therefore, we decided to build complex scientific phenomenons like
above so that our app focus would be on serious potential educational 
content for senior schools that has not been created before.

We took our project to IIT Bhubaneswar this time, it was AR/VR 
conclave organised by IIT and professors from all IIT’s IIIT’s and 
IISC Banglore had come who were working in this field, it was a 
hackathon and we were judged five times. This time we Won! 
Although it was 3rd position but it was IIT, the tag that everyone wants!!!

Winning losing is always a part but what is most important is the
learning and the journey, and every time this project Won was 
when I was focussing on my learning and least expecting it, 
the process rather than the result, during our Nationals of 
space apps I was too much focused on making something 
that could make us Win this time too! but as you know I Lost! 
But a lesson learned for the lifetime that I already read somewhere, 
in Shrimad Bhagwad Geeta! -focus on karma rather than the fruit.

HealVR



HealVR was one of my most ambitious research project 
of 2019, where a VR system was developed to help 
reduce pain among patients that involve therapies including 
Dental Care(Tooth Implant, Tooth Fillings, Root Canal, etc), 
Arthritis Therapy, Wounds Redressing, Minor Surgeries, etc. 
Therapies duration of fewer than 5 hours involving mild to 
intermediate pain were targeted for this project. 
There was also a mode for hospitalised patients who can
have a blissful experience and get out of the ill-hospital vibe.

The patients have to wear a VR headset and then they 
would be in a completely simulated environment controlled 
by doctors or patients itself if possible.There were different 
kinds of scenes ranging from a simple underwater scene, fully 
explorable forest garden scene and a highly engaging shooting 
scene to target severe pains. 

There were a total of 6 scenes fully created by us for different 
types of pains and patients.The whole system of Virtual Reality 
Pain Reduction works on the attention-distraction mechanism, 
think of it like when you were a child and had fear of the pain of 
injections, the doctor might have told you to see towards your 
mother or somewhere else or watch TV during that process and 
it happens that you weren’t able to feel the pain because you
were distracted. The same simple phenomenon, when expanded 
with the tech of Virtual Reality, was observed to do wonders in case 
of different types of pain. A huge inspiration for the project was taken 
by research done by Hunter Hoffman for the treatment of patients 
of burn pains.


This project was displayed on 16th ICDCIT(International 
Conference on Distributed Computing and Technology) and 
was later published in PIC 2020 (ISBN: 978-93-5391-188-1) 
and is still currently being worked on.

Special thanks to Praddyum as this would not have been possible without him.

2019 GameDev in 1 minute

Here is my 2019 compilation video of ever game scene I developed. Hope you all like it, if you have questions or something to say about this video or of any of my projects, you can do so by comments!

Getting started with Game Development

Hi! I’m Sanchit Sharma, a young game developer, currently a student at KIIT. How would you feel if 
you could change your reality and create a whole new one? A reality which is maybe based in space
with asteroids attacking a spaceship! Or maybe a reality-based in the ocean where you try to fight the
pirates.Well, creating a new reality is not possible in the real world but it is definitely possible in the 
world of Game Development.And the popularity of Game Development is only increasing. This can be
because video games are becoming more and more popular and people now want to not only 
participate in these worlds but also create them!!!

Is Being a Good Game Player necessary for Game Development?

There are many people who assume that if they are good Game Players then they will 
definitely be good in Game Development. Well, don’t make that mistake!!! If you are a good 
Game Player then you have some advantage because you already know something about 
game stories, players, levels, etc. But that’s it! Actually making games is boring many times 
as you have to code, design and work around on many things at which you don’t initially 
succeed but the end product is the reward.You will feel so much satisfying that you have 
created something of your own after a hard brainstorming journey of making it. The only thing 
that will keep you on track of making games even after all is the passion for games and 
nothing else, believe me.

Where to start?


  1. Choose a game engine: As you are a beginner in Game Development, it is best to 
    start with a known Game Engine. There are many available such as Godot which is free 
    and open-source, Unreal- which is used at the industry level to create stunning games 
    and Unity game engine which is used by almost everyone from indie developers to 
    industry level players in the market, from AR/VR to real-world mobile apps, all made 
    with Unity. My personal preference is Unity itself as it provides all tools to get you started 
    as an indie game developer and you can also make real world AR/VR mobile apps and if 
    you are too good at Unity then you can use it to make almost any kind of app that you can 
    imagine!
  2. Create a basic game: There are now several official Unity YouTube videos which can help
    you get started with creating your very first basic game, don’t try to create anything very big
    at first, in fact, create something very small, it sounds weird but you need to hold yourself 
    to give a good start and once you are a pro at Unity or Unreal you can open the fences and
    imagine anything and try to create that one.
My very first ‘playable’ game was Project Boost, a 2.5D rocket thrusting game with two levels.


                                                                 Project Boost

  1. Move on to 3D: When you have created your first basic game which should probably 
    be 2D or 2.5D for it to be called basic then move on to learning 3D concepts on game 
    engine. My second game was a basic 3D ship flying game which I learned through a 
    course on Udemy by Ben Tristem and Rick Davidson, believe me, they are the best 
    teachers.
     
You need to revise some maths and physics for yourself here which makes to our 
point 4.
  1. Learn 3D Graphics and Associated Maths: It is not possible to make a video game 
    without graphics and so you need to learn about them now. 
    The maths commonly required for 3D Graphics is Linear Algebra which mainly deals 
    with linear equations, matrices, vectors, etc. 
    If you understand these concepts, you can easily manipulate the 3D world of your game 
    to achieve miraculous effects!!!
  2. Publish a game: It might not seem how important this is but you need to publish your 
    game asap, anywhere publish it, it is not to be on PlayStore or Apple Store, publish it 
    because it gives you a push onto your learning and game-dev journey, don’t wait for your
    big awesome game debut, that’s not how it works, publish anything small but you should 
    have a good feeling about your game. My first game published on PlayStore was 
    Mad-Ball Breakout and that’s the only 2D game I have ever tried to build because 
    seriously I don’t like 2D as I haven’t been a 2D game lover myself.
     
  3. Learn random concepts: Once you have the idea of the game engine after at least 
    six months or so then you can just learn random engine specific concepts like 
    Dynamic Scrolling, Optimization, Post Processing Stack, etc.
Here is an image of before and after applying Unity’s Post Processing Stack features,
 
Before Post-Processing,(below)
  
how much detailed and good the scene is now, details such as Lens Blurr, detailed fog, detailed and 
darker shadows, HDR, etc.

What are some Online Resources to Learn Game Development?

There are several resources available such as books, courses, and official videos, the major problem
with almost all of the books and most of the videos is that they are outdated, the process of making 
and publishing a book takes as much time that the information in it gets outdated, if you are following
a video try to make sure that it has exactly the same version as yours otherwise you will have a hard 
time figuring things out and will eventually leave it.
Udemy Courses are really good but just see the ratings and reviews of students before actually 
opting for the course, but by far I think Udemy is the best bet for now and then comes YouTube, 
you can always go on and contact me.
