Phizix - "Super Mario Galaxy"-style gravity

I knocked this up because I was bored :grin:
It's a Phizix example that has a small 'planet' with it's own centre of gravity. The box will always fall towards the planet, much like the gravity system in Super Mario Galaxy. Since it worked, I figured I'd upload it for you guys to enjoy :)

Oh yeah, if anyone can teach me how to make it work with multiple planets and multiple boxes, that'd be great ;)
(You'll probably notice the Alterable Value B setting the distance for no apparent reason... a previous attempt at getting it to work with multiple planets =P ).

Also, you can click anywhere to move the box to that position, or press space to apply a random force to it. Try to get it orbiting the planet!

Nice work. I made something like this before... actually, it was pretty much the same. :P Same "bug" though, the boxes are bouncing around, which is pretty bad imo.

Yeah I also tried this... with same bug hahaha

Bouncing? How do you mean? I didn't notice any bouncing on my computer

I think they mean how the box will never come to rest once it has landed. Probably has to do with the planet being perfectly round.

Ah yeah, so it does. I wonder if I can fix that...

Oh my Goodness!

This is exactly what I was looking for! Thank you!!

:D

The reason that multiple boxes can't have separate gravities is that with Phizix, each body does not have it's own individual value for x and y gravity, rather the World itself does. This means that while multiple planets are possible (using a little bit of maths), more than one body is not.

The only way I can think of doing this with Phizix is to not use Phizix's gravity, rather; apply a force in the direction of gravity. Again, a bit of maths, and it's all possible.

Yeah, I'm currently trying that, and it seems to work :)
Just gotta ammend the loop to fit multiple boxes xP

Wow you did really good on this! It's be cooler if the gravity would get stronger by proportion with planet size. he reason the box keeps moving is because the direction of gravity is contantly changing, where as you use a vector movement with some custom physics this might be smoother. Still great work for being bored!

Nice example thanks
