Unity Tutorial - Solar System with Unity Physics

Hello, I want to make a solar System but I understant why do you increased the earth mass by 15 ?

Is there any way to download the assets directly? Someone please reply

WOWOWOWOW!

thank you for this great tutorial.. merci

I can't get the moon to orbit the planet

Do you think blender is better than Unity in rendering solar system?

Where can i find a 3d models like These planets and the sun are wonderful

What if i dont have the transform.right, how could i do the same thing?

Excellent tutorial, thanks! I got it working in Unity 2021.3.24f1 but my code is identical to yours and all the RigidBody mass settings and I turned off "use gravity" as you did, but the Earth takes off on a long comet like orbit. I had to multiply the initial velocity by 0.7 to get a perfect circle, which is weird. I just realized 0.7 is 1/sqrt(2), and indeed adding 2*r solved it and makes it work, but your code didn't have that and your code matches Wikipedia. Weird. Thanks for all the other cool tricks with TrailRenderer and speeding up project time.

A beautiful simulation with physics formula on Unity, beautiful !
I'll reproduce your code I guess. And after that, I'd like to add code to simulate planetary rings (or proto-solar disc, or accretion discs), like Saturne, Jupiter...

In realtime, is the G float member different for each celestial ?

i love it

As expected, it doesn't work. Oh well, another tutorial fail.

Whoah, this is awesome!
Thank you! Super video, it is short, explaining a lot, and have clear demostration!

Greetings. I followed your tutorial for the shader graph star and this one for the orbits. However, my planets are not dynamically lit. Could you do a video on lighting in Unity or recommend any good ones. Soulcraft looks good, btw. Hope to see it released soon. Thanks.

Thank you for the video!

ur code working so good uhm how can i ask.. can i use this my education project?

Ty so much for the tutorial, helps a lot

It's so cool! Thank you very much!

Very useful video!
It would be interesting to see what could be done from this project

Cool stuff! However, there is an error in the formula for velocity in an elliptical orbit. The (2/r + 1/a) should be (2/r - 1/a). Also, on the distance scale chosen, the earth and the sun would be fifty times smaller.

instead of the planet moving towards the sun, the sun is moving towards the planet in the gravity part. cud u pls lend a hand

Awesome stuff, how can I make the planet movements significantly slower but still make it work? new to coding sorry lol

Why is your channel so small?
Great content!
You deserve so many subscribers, i can understand something so complex in just some minutes, that is amazing!
Congratulations.

Err i don't mean to be pedantic but i don't see Unity Physics being used here and i'm presuming this is using the built-in Physx physics engine?

I get " operator '.' cannot be applied to operand of type 'void' " error message :/

Hi, could you make a tutorial to make the orbit in the shape of an ellipse? Very good tutorial by the way.

Hey man, I have gotten it to work with the circular orbit! However for the elliptical it's not working. Seeing as this solar system is scaled down, what values do I need to use for the values: 2, 1, a in this part of the equation -> (2/r - 1/a)?

Nice tutorial, really thanks. But you have something about a 'HUGE' system star, Solar or, at last, what is the best way to do it without broke the engine (because this size of a space, planets, etc)?

Amazing video, I've been looking for something like this for a while. Just what i needed.

Honestly this is the best tutorial about this topic

thank you, that helped me so much to figure some problem with my project, would it be possible to make a video on how to predict the trajectory of a planet with a linerender or something?

Just wondering why did you add two foreach loops. I am sure there is a good reason, but I just cant figure it out and I am trying to learn C# so was curious.

hi , nice video but i have a question - when using urp my textures dont apply to my object. any solution please??

hi this was a wonderful tutorial but im having a problem where after i added more planets the sun started to wander. like it wanders in a straight line and pretty fast too. i get that it gets pulled a little by the other planets but it's literally wandering to a whole nother galaxy

hi! this is a awesome tutorial, im making my own solar system simulation too, can i get the codes and the mass tables from somewhere?

thanks life saver. < 3

I dont know if this is just me but my planets like to go out of orbit and shoot off into space.

could you project shadows and add a fixed pov from earth surface? Even without earth rotation on its axis, to see the Moon phases? That would be amazing...

I luv you.

Thank you soooo much!!

I knew the formuals and everything but wasn’t ready to implement it but after seeing your video I got the faith in myself to implement it and now I have my own solar system.

So I have a weird problem with the velocity. When I add the velocity part to the script my earth just flies away. I copied the script line for line. Any idea why this is happening to me?

r u scientist ? dude u rock !

I followed the gravity script but when i compile the script i get two errors saying ';' and '{' I double checked everything and nothing is working

quick tip - I think if you press Shift+F it will lock on to your selected gameobject in Scene view, so you don't have to manually scroll the screen with your mouse

Nice video.
Is deformation of planet w.r.t the nearest Celestial possible?
Like if a planet goes near the sun, it will deform and vapourise.
