Day and Night Cycle Development Diary

Hello!

This week, we wanted to share with you how we did the day and night cycle and astronomy system in Paralives. Anna prepared a breakdown to explain how it works.

But before that: good news! We hired a new programmer and a new 3D animator on the team! They will start to work with us soon and we will introduce them to you then!

This post is for Patrons only so please don't share it's content, thank you! :)

 

Day and Night Cycle Development Diary

Hi everyone, it’s Anna! I’m going to show you a bit of the astronomy system of Paralives and possibilities for its customization for modders, that you partly saw in the latest sunset video. I hope you'll enjoy this diary!

As you already know, Paralives already has its own astronomy expert, which will evaluate my first month of work on the team. Yes, I’m talking about Maggie!

Maggie, excited about being a tutor, even if we confirmed that active schools aren’t planned for initial release...

Simulating a planetary system

Maggie: A long time ago, the universe expansion caused by the Big Bang led to the formation of our solar system, as we know it today… 

Anna: Wait... Maggie, please don’t lecture the patrons! Let me introduce them to our very simple simulation to begin with. 

So, recently we decided to improve our basic day/night cycle by simulating planet and moon orbits, so that we can easily reproduce somewhat realistic seasons (making days longer in the summer and shorter in the winter), in addition to other fun things for modders to customize! Below is a sketch of the system, with the parameters that are available for modders to change.


Our basic solar system simulation program brings all these parameters to life by computing all rotations and positions of celestial objects during in-game time. Then, the positions for all non-Earth objects are computed back from the Para’s point of view, which will likely be played from somewhere on Earth. (Sci-fi DLC is NOT confirmed!)

Maggie: Do I see… a planet? Where are the other celestial objects, like asteroids? Is the distance between them measured in A.U. (astronomical unit) or in bananas? I have so many questions, I can’t wait to put my hands on this mod system! 

Anna: Distances and sizes are not used for any computation, they are only visual parameters. There is no need for modders to implement a realistic 1,392,684km diameter Sun 3D model! Durations of orbit revolution are minutes of game time, but a year in Paralives is likely to last less than 365 days of in-game time, so players can enjoy the different seasons more often. 

There are only 3 types of celestial objects for now: stars, satellites that revolve around Earth and planets that revolve around the stars. However, we can add as many as we want and customize them all differently, they will be visible from the sky in game! 

Can you tell that I’m hungry?

Maggie: Ahem, not to be that girl, but… I think you missed that Earth is rotating around its own axis, in addition to its orbit around the Sun. 

Anna: Of course! Its rotation duration, i.e. number of minutes in a day, can be customized as well! Earth is also tilted 23° along its axis, which is the reason why summer days last much longer than winter days. Latitude and longitude can be changed so that seasonal daylight looks like what you can find in real life all around the world!


Visual parameters

Maggie: What about stars and constellations? What will I be able to look at through my telescope? 

Anna: I’m afraid that you will have to wait a little more for these features… For now, you can admire the Doggo Sun or anything you would like to replace Doggo with, thanks to the modding tools. You also noticed in the last video that there were different sky colors. This brings us to other visual parameters, sunset and sunrises! 

Let me show off the moddable parameters for each celestial object:

Modders will also be able to fully customize each stage of the skybox color. In the future, we also plan to deal with different sunrise and sunset color setup, each occurring at a given probability.


Conclusion

Maggie: As an astronomy expert, I would like to say that it seems really impressive for beginners like you to have implemented such a system! 

Anna: Thank you Maggie! A wise statistician once said “All models are wrong, but some are useful”. This is really true for game development too, as we want a trade-off between realism, simplicity and fun! We don’t have to be experts in astronomy, psychology or even architecture to make a cool life sim game, but as an indie team, we’re excited to learn all of this by ourselves, and that’s what makes game programming and game design really fun! ...and sometimes can be quite challenging too.

Me when Alex asked if creating a Tatooine-like P-type planetary system with two stars would be possible

Last but not least, we want to make our modding system as accessible as possible! The current settings of all the game parameters are actually considered as a mod for the official game. This is why modders will be able to tweak as many parameters as the Paralives team itself! Here is a sneak peek at our current in-game modding UI: 

No need to manually edit hidden files for modding Paralives! We are working on visual interfaces and tools so modders can easily change almost any hidden variables and settings of the game.

This concludes my first dev diary! Thank you for all your kind comments about the sunset video, I hope you enjoyed seeing a bit of the backstage too! 

Cheers, 

Anna 

Day and Night Cycle Development Diary

Comments

Wow this is great! I love day/night cycle in Minecraft so its awesome that it gets more attention

"[...] easily reproduce somewhat realistic seasons (making days longer in the summer and shorter in the winter" YESSSSS! This alone has me so excited.

On the topic of schools, what if schools were online, just as they are now? It might help younger players adapt better long-term!

j

I know this is an older post but I have friends who work as teachers and they have similar boards in their house (but with secondary school subjects) which they go over for their lesson planning, and so the first thing this screenshot made me think was, it looks like Maggie is practising for her first class to teach on her own, fresh out of graduating and it just made me feel all hopeful for all the potential this game has!! Love it :)

This is wonderful! As a professional astronomer I am so impressed with how much thought and realism went into this! If you need any help with the conceptual aspect of stars/constellations I am more than happy to help!

Is it possible to have an option to turn on/off the celling? I think having celling can make you feel like the para is in a room :)). Anyway great work !

Iris Duan

I would love if in the future we could build homes, cities, and Paras on other planets in the solar system and have a solar empire haha or like include giant space structures like Dyson cloud or O'Neill Cylinder! I would love a Scifi expansion but based on realistic science. Thank you for your hard work!

I'm so excited about the modding opportunities! I'm not huge into creating mods, but this would be a great way for me to start! Thank you for keeping modders in mind throughout your process. I'm excited to see what's next!

Has Maggie been sunbathing on the patio of that flat?? Sounds like fun! :-)

Jennifer Huber

Is it me or is Maggie much darker? 😍

KendraDior

Wow this is amazing!!

Super Mommy811

Ayy! Welcome to the Simulation squad everythings great down here except someone keeps stealing all the cookies... but yea apart from that its lit Af!!!

You know the modding community is gonna be lit when the developers themselves are encouraging it!

Found this project the other day and immediately had to drop something. If you guys can deliver a experience like some of the older games of The Sims franchise, I'd gladly continue support this project.

Brandon

I really like what is happening every time I see an update it makes me even more excited for this game. :)

Gary Hardt

I really respect the time and love and energy that goes not only to the game, but also to keeping us updated and entertained. 💕

This is incredible! Thank you for making modding simple! I love the idea of customizing a game but don’t know how to do that.

Grace Sivils

Keep up the good work <3

Tini

Wow never thought they would actually include this. Keep it up

I love how innovative you are with making modding more accessible!!!

Um Wow, first of all Anna beautiful Diary entry❤️ I’m blown away at the amount of detail put into this game. I’m speechless, such an amazing dev team ❤️

Simmons

I can’t wait till this game comes out. Hopefully they’ll release a demo later this year ❤️

this is freaking FASCINATING. i'm fangirling so hard

paleio

The amount of detail with this is amazing! I'm gonna have Saturn orbiting the Earth just because, now. Oh and I can change the color of sunrises or sunsets? :D Ya'll have once again blown me away! Keep up the good work.

Estoy impresionado con el nivel de detalle que están poniendo en el juego. Mis felicitaciones a las personas involucradas. ♥

This amount of detail and customization going into something the average player probably won't even notice is sooo good! This will be great for storytelling! It also solves the one criticism I had of the day night cycle video -- the overly blue nights. I can just mod that through the game's interface! And does this mean solar eclipses will just naturally happen from time to time when things up there align? Wow, guys. I, for one, appreciate the attention to detail as I always notice the details (or lack thereof), it just adds up to make the game world feel so much more real and less faked. It IS a life simulation so it also just makes sense that this should be simulated. I hope, instead of taking shortcuts, you guys do this same in-depth simulation for other similar systems as well. I'm excited! :D (PS. This one feature has more depth than main features from other games. I'm just sayin' that's exciting!)

ramaru

Thank you for this, Anna! And of course thanks to Maggie, too 😄 Super in-depth, amazing attention to detail as usual... aahhh I just get so excited for the progress reports and lil views into the process you guys are going through.

bingbong

Alex and the team, you guys are very, very clever! (and I'm not talking about the actual solar system design itself). This is going to explode in certain communities in the media! Congratulations, and that reception will be very well deserved!

Fran Smith

The attention and effort you have put into this game for what would normally be considered a minor detail is incredible.

Thank you, Anna, for sharing this! It is so refreshing to see what goes into the creation process!!

Jennifer Huber

I love how in depth you've went for this, to simulate a solar system for the day/night cycle rather than just, well, a basic day/night cycle. That's amazing!! Tbh, I don't like to think of the Para planet as "Earth", it's not in the Sol system, it's in the Doggo system. :P It's an alien world with human-like creatures, the Paras! Or maybe an alternative universe? Who knows! It's fun to theorize and create lore for a game, haha.

It was necessary for the seasonal features! :)

Anna

This seems like it would be really useful for creating a neighborhood on an alien planet. I really appreciate all these extra modding features!

Dizzardy

It's nice to see the 'behind the scenes' of how things work, like seeing a play on stage not realizing the crazy business happening backstage all at the same time! Thanks for keeping us always at the forefront in sharing the creative brilliance of what we'll be playing hands-on in the not too distant future. I look forward to spending time in Maggie's world.

tey711

While this is really cool.. It’s kind of unnecessary...

Tabitha

I gotta say I'm just blown away. It's incredible how much thought goes behind something as simple as 'a 24 hour day' with this game. The fact that you are taking into account the seasons and the tilt of the earth... WOW!! And those modding possibilities have me so intrigued! I'm personally no modder but I cant wait to see what they come up with. This is incredible! Keep up the amazing work, team 🖤🖤🖤 we cant wait to see what comes next

This game is to simulation gaming what rock and roll was to music 🎵.

Judi Dielman

This is going to be amazing and so helpful for the builders in the community, and as a someone who’s a builder Thank you so much dev team!! 😍😭😍

S&M Gonzalez

i loove the idea of having different durantions of days and nights during each season! I haven't even thought that this can be in the game!

Can I just buy the game now? I don't need game play, I just want to toy with this. I'm so happy you guys are adding all of this in.

BreakingGaia

This is AMAZING! The astronomy nerd in me is totally geeking out over this. I'm so beyond hyped for this game. I keep telling myself it's an indie game and not to get my hopes up that it will be the best game ever but when y'all release things like this it's hard not to get super excited!

Katie Bellissimo

I know this is supposed to be patrons only but I hope you show it off publicly soon because this is insanely cool and I honestly think its gonna get a lot of attention (:

nemo

Supernatural (I think we call them ParaNormal here!) is not planned for the base game. If it makes it though it would probably be in a DLC in the future.

Anna

This is so above and beyond the scope of anything I could even hope a sim game would develop in terms of detail! My head is spinning in the most wonderful way and I cannot wait for this game! Also, as someone who loves to tinker and tweak but was always intimidated away from editing game files, I'm beyond thrilled that the devs are creating a visual modding interface that should be much more accessible to players like me.

PinkLyon

This is so creative & I love it!!! Keep up the amazing work y'all!!!!💝💝💝

Erica⛓️✨️

Yes. The sky is the limit. Modders' heaven.

OH YES! I don't think about that before! The Para-description and Para-dialogue can be very fun and entertaining!!!!! Hooray!

The dog in the spaceship gif really describes me!! LOL.

PS. Please don't be like Oooblets devs. Keep up being creative, Patrons bonding and building the tight relationships like this. Even one day you are bought with HUGE MONEY by the big game company, please stay being "Alex and the team we all love and adore". Please.

I love the part when Anna said she was hungry. LOL!!!

I didn’t understand this😂x

Lenny

This is absolutely brilliant

Famicom Guy

Can't wait for this game and you guys are doing an excellent job! Can i ask a question? As a Supernatural freak! With Planets on the horizon, does this mean we will have Aliens? or any Sups for that matter?

XXXTigger

This is amazing!! Anna, you’ve presented this diary in a highly entertaining way and I can’t wait to see what kind of writing you do in-game for popups/chance cards/etc.😅Seeing the easily accessible modding tools is so exciting as well!

Aaron

This looks amazing! Tbh, I didn’t expect this much detail in even “background” things like the sunset. Super looking forward to this game!

Zeevryn

Wow this is really complex good job

Ella Pilchik

This game just gets more and more iconic with each new bit of information. So excited for this

Jordan Harrison

Amazing work! ❤️

ღPark Nikkiღ

So cool! Love that we'll be able to see the solar system from the sky, that little juicy nugget that some different sky shading patterns can happen at different probabilities, and the modding UI! 👌 Looking good Anna!

Holy shit, this is above and beyond. Keep up the good work

Yodasbigdick

This game just keeps getting better and better!! 😍

This is AMAZING!!!, well done Anna

Bianca J

Oh, I hope they'll be possible. 😍

Aleksandra Gołębiewska

I'm so happy! I will be able to create my own shades for the sky🥰...

Aleksandra Gołębiewska

Great dev diary! This answered all of my questions about the system perfectly in an entertaining format.

Gina Tonik

it just keeps on getting better and better doesn’t it 😩

Luciana

"Sci-fi DLC is NOT confirmed!" -- Okay but it's not NOT confirmed? 😉

Megan Santucci

Absolutely amazing. I didn't expect an actual simulation of the solar system would be used for the day/night cycle. Would that also mean solar/lunar eclipses are possible?

You guys seriously blow me away every time! 👏 👏 👏 👏

This was brilliantly written 🤣🙌🏼 loved it! Reminded me of the style of Terry Deary in his series Horrible Histories/Horrible Science ❤

ZombieZmaj (Jenni)

Loved reading this! It's so interesting to be able to play around with the settings like that, we'll be able to create truly unique worlds. The format of the diary is also a good choice. It makes a topic that can be complicated very easy to understand.

Zedef

Oof. that’s pretty amazing.

Nazly Sabet

I'm so excited for the SCALE of the things modders are gonna be able to do.

ThatOneCamel

Absolutely wonderful 😍 thank you for such an amazing creation ♥️♥️ P.s. I love how you included Maggie in this, it was super cute and pupper meme 😆 ...it be cooool if Sebastian did the food thing if you guys plan to show us that, at some point too 😆😆

OMG, this is AWESOME 😍!!! I'm so hyped now xD

This is so cool! And "Astronomy 101 with Maggie" is sooooo cute!!!

Phoenix

Hot damn, I am so keen to have moon-obsessed parafolk ie. me taking screenshots of them looking up at the night sky 🌙

I ADORE being able to choose the colour of the sky and sunset, that's gonna be amazing for brighter and more cartoony gameplay vs. more grim and realistic gameplay. Also great for sci-fi games.

just the thought that I can make the sky purple instead of blue...oh god and create a fat ass moon like

sofst

This was so fun to read. I’m so excited!!

Alkisim

Love the detail 🙌🏻❤️

stephanie mulcahy

you guys are iconic

I read everything and I’m speechless, guys you are amazing I’m so so happy with this 😍😍❤️👏🏼

Camilo Quintero

I love this personalization of the game!! Even if I don't do mods, just knowing that's an option is awesome!! I love how you presented it too!!! Keep up the great work!

Thank you for the breakdown, Anna!

Mackenzie

This is amazing! I love this, how customisable everything is and the freedom around it all ❤️❤️ can’t wait to actually see this in real life and try it out!

Hearing this makes my inner space nerd throw a party inside! I'm so excited to see how this will affect the world and what in-game events may come with this type of system.

Love this so incredibly much 💙💙 this was a great read and sense of humour 😆

Anna

I love the details! Thanks Anna!

Amy Wallis

The solar system implementation sounds very cool, it'll be nice to see a 'real' rendition of the solar system in Paralives. Keep up the good work! 💕💕💕

OMG I love this! Anna this is amazing to read and it brightened my day up how you portrayed it all!! 🤣🤣😝 and I’m in love with that chair outside! Can’t wait for more news. Love you team 👏🏻🥳❤️

Becky

Wow, that’s very detailed and wasn’t expecting to see it from this. Maybe too much customization for me but at least it’s nice to know it’s there!

Stephen

It’s never been included in any sims game but we should be careful about comparing them since they’re likely to be very different games

Pcrafter1

Oh wow this is so cool!!!!

I don’t recall seeing this new feature in the Sims franchise, but this looks and sounds so cool!
