Gyroscope - Phun and Algodoo Compatible

Postby xplane80 » Sun Feb 07, 2010 6:50 pm

1. make a Square and a plane underneath
Image
2. rotate square 45º
Image
3. place circle at left corner
Image
4. add hinge to circle
Image
5. drag the circle to the right corner leaving the hinge where it is
Image
6. place a hinge on the circle at the right corner
Image
7. click play and watch

this tut is for staying vertical is you want horizontal, place the circle and hinges vertically instead of horizontal. also experiment with different angles E.G. 45º 60º and more.:)


This was copy and pasted off the tutorial I did on the old phunland forums.

Here's other efficient method I found few weeks ago (phun and algodoo compatible too).
Make some fast collider. Set it's oncollide to (e)=>{controllerAcc = (-controllerAcc); density = 100+controllerAcc}; Then set it's density to 100, and geometry controller to 90;

This works much the same way as above (only mass changing instead of shaking it), but it's less shaky.

That is another good method but I prefer this because it only uses 4 parts and NO scripting!!!!

It's cool because of the non-shakiness but all the same I prefer the mechanical method because when you want to accelerate an object with the scripted stabilizer its acceleration isn't constant and wiggles.

Unless you use two mass changing objects in such way that their total mass is constant

Not always. If you are accelerating very fast, then it will not be constant.

If they were aligned vertically and you're only moving horizontally, it would work. Otherwise, you'd have to use four.

Or make them really small and place close to each other.

you can use it with one of them having density to be a sin of sim.time, and another being the cos of it. care should be taken not to get into negative densities though (like {(sin(sim.time * insertconstanthere)/2) + 0.5) + uselessvaluesothatitdoesnotgetdeleteditself)*insertanotherconstanehere} ,

this works because algodoo actually calculates rotation by basing itself upon the mass center of a body. both of those "pseudo-gyroscopes" just change the mass center really fast, one by mass shifting(which causes the shakiness), and the other one by warping the mass to another dimension and beyond :lol:

Great Tutorial, Worked Fantastically

I even Created a Gyroscope Car: http://www.algodoo.com/algobox/details.php?id=39963 Enjoy :D

This is just about the best stabilizer that you can make. 1, because it uses 4 freakin' parts. And 2, you can make it really really fast. I'm glad somebody found out a way to make a simple stabilizer that works, instead of having one that spins a scripted ball to stabilize that doesn't even work very well (RaUnit3 :roll: ).

You realize that in Algodoo 1.7 there's an even easier one, right? inertiaMultiplier = +inf

No, I didn't realize that, because I'm not good with thyme, and I don't use algodoo, like I've said thousands of times -_-. You know what, i think I'll just put it in my sig that I don't use algodoo. :roll:

Ah, that's right. Sorry, I forgot. :oops:

Also, the new RaUnit doesn't really work because they he had to change the way it worked to get around the new hinges. The old one was awesome, until hinges were fixed. :(

You mean RaUnit 2, or 1? Cause from what I've heard, RaUnit 1 uses springs to work.

Yeah, the RaUnit 1 uses springs (those were fixed and it doesn't work), and I think the second one uses hinges (same problem).

There was three!
My mistake, the last one uses thyme.

So can you use all of the RaUnits in Phun version 4? I'm pretty sure I wouldn't play v4 all the time just for RaUnits, but if I wanted to, could I use them all in v4?

I don't think the RaUnit 3 will work in Phun 4, but I know that the RaUnit 1 will (maybe 2).

Alright, well then I guess I could transfer one or two of my scenes that need stabilizers over to phun4. :D
