Gravity System

[vale blaze]

i need help to rotate the planet towards the planet or away

[wet sparrow]

Explain a bit more

[vale blaze]

so it speed up as it goes closer to the planet but doesnt orbit like rotate around it Pancake992#9400

[vale blaze]

there was another but broke and got taken down but i got some clips

a diff game

[verbal egret]

@vale blaze get pos of object you’re moving and subtract it from the position of the object you want to follow

Then add velocity in that direction

And do the same for the other one

And for 0g just add velocity at speed 0.33 with a direction of 0, 1, 0

That’s not exactly how this person did this but that should put you on the right track

[verbal egret]

Also make sure to use vector normalize before wiring this to the velocity

[verbal egret]

You could use distance for this

Something like distance x -1 + 50 or something like that and put it into the speed

[vale blaze]

all planets use pistons

[verbal egret]

Weird

[vale blaze]

easyer to stop and start

and always get a constant speed

better to get distance

[verbal egret]

Yeah true

Could also do custom physics

[vale blaze]

if you try a 0 g velocity you cant add anymore velocity in any other directio its a rr bug

if you keep on addind 1y it cant move any other direction

with the 3 clips of the broken game it used pistons

[vale blaze]

this is the circits fornow

[oblique leaf]

Are you interested in something like this? I put together a quick demo. Trying to attach a video.

[vale blaze]

Yes and Does it use pistons

[oblique leaf]

No, it sets the position directly with “Set Position”. It might be possible to rework it as pistons, but this is smooth as-is. https://cdn.discordapp.com/attachments/907325246544154694/1022327483925798952/00435185673eea24d48ca2ac0c677f22.mov

[vale blaze]

but is it editable

[oblique leaf]

You can modify the circuits however you want, if that’s what you’re asking. Idk exactly what you’re trying to accomplish, but this is just a demo to show how bodies in orbit act. Here are the circuits that power this. The bottom row initializes some stuff when room launches. Above that, there are 3 distinct rows. One for each planet. The “sun” settings are in the top left. Then I have a button to play/pause and change the sun mass (and therefore the attraction of gravity).

[vale blaze]

so with this could you get 2 points and use distance to get speed

to help use vector points

[oblique leaf]

Not sure 100% what you’re asking, but these circuits allow a moving object to be affected by the gravity of another object.

So it’ll provide the values for where the moving object needs to be.

[vale blaze]

scetch

so the distance is the speed

of origin

[oblique leaf]

Yeah, every frame the next point is calculated for where the object should be. So you’d have the current location and the next location. You can get the distance between those points or “speed”.

[vale blaze]

also can you take a image of the circit board

image 1

[oblique leaf]

Get Acceleration:

I had my Gravitational Constant as 0.01. Higher values means stronger gravity. Same thing with mass.

[vale blaze]

can you make it an invention because i understand it better

[oblique leaf]

Sure. https://rec.net/invention/1500221915415804166 when placing the invention, I suggest your character be facing Vector direction 1,0,0. The demo will look better because of the “Initial Velocity” values.

[vale blaze]

thanks

[oblique leaf]

To know which direction 1, 0, 0 is, throw a vector component down. Rotate it (left, right, forward, back) until it’s value is 1, 0, 0. Face the same way the arrow is facing then place invention.

[vale blaze]

i was playing around with it and it breakes after after afew seconds

[oblique leaf]

Too strong of gravity can cause a slingshot effect, launching it out of the solar system. Bad Initial Velocity can give it a slingshot orbit as well.

[vale blaze]

it also does the beebing noise

[oblique leaf]

If it slingshots away and gets too far, that’ll happen.

[vale blaze]

oih

[oblique leaf]

Yeah, “Initial Velocity” value is set when room loads. Otherwise you can force set the velocity with the exec down below. Velocity vector should be about 10% of a normalized vector magnitude to avoid immediate slingshot.

But this is a very close approximation to real world orbits mechanics. It uses the proper formula, but it’s just hard generating a proper orbit. I spent time positioning those planets precisely and coming up with the specific initial velocities.

Btw… “why” initial velocity is important: if there were no initial velocity, then the object would be pulled straight into the sun

Initial velocity is tangential to the sun and gives it its orbit.

[vale blaze]

since its a demo if there is a full version include gravitational pull from other planets

[oblique leaf]

That would greatly increase CPU heat but it is doable.
