Still no go

It works fine for me. On 2 different machines. Are you sure you have SketchyPhysics2?

@CPhilips
Thanks for the file. But when I press the 'Play' button the the wheel simply brakes apart

I might have attached the wrong file. I updated it. This works with SketchyPhysics2 beta 1.

Solo's model with physics joints.

... wonder if anyone is figuring out a way to control the controllers from another program. If my mouse on the screen in controlling the slider bar it shouldn't be too much of a push to have a program do the same.

Maybe. What did you have in mind?

:thumb: Do you have a Warehouse account? I'd love to see some models...Hey, I cant use the ossciator or the magnet joints.

Search for "SketchyPhysics" on 3d warehouse. There are tons of models.

Oscillator joint was replaced by a setting in piston. Magnet doesn't work yet.

CPhillips was playing around with somethng similar http://www.sketchucation.com/forums/scf/viewtopic.php?f=57&t=2570&start=0&st=0&sk=t&sd=a but SketchyPhysics is a bit distracting. It's good to see this sort of tool revived.

I semi-finished that thing I was working on. Problem was that it was really slow a reasonable size model could take minutes to update. Maybe someday I'll go back an optimize it.

Shear looks like a handy tool to have!

I found all that want except a simple direct straight move displacement
from A to B of a simple box flying in the air horizontally (without wheel)!
Piston? I don't want the return

Try a piston with min=0.0 and max=100.0

@unknownuser said:

Amazing

Silly question : Terrain is flat
is it possible to start a car without to catch it with the mouse?

In one word how to start an animation without see the mouse one the screen?
(when the object has not it own "energy")

Thx by advance

Not quite sure what you mean. Servo, piston, motor and spring can cause an object object to move without using the mouse.

ok well i tried to make them all convex, and in fact i got some results.
yet when i tried to do three rings, it failed to work, as if something was getting stuck on somehting else. When i ran the combinations of the rings, two at a time, they worked fine.

the lines in the model i am posting is probably because i copy and pasted the rings.(without the joints of course)

i tried to attach the file though for some reason it is bigger than 512 kbso if you'd like to take a look at it, PM me your email and i'll send it to ya

Its the same problem. The rings need to be broken up into more pieces. Each ring should be made with one convex object per segment (24 of them in this case).

Easiest way to make a ring is to create one segment, group it, set it to convex, then use rotate and copy to make the rest

Oi! That is purty.Smile

Did your really try simulating 2 million cars?

Try zipping it. Or post it here:

And Ill take a look.

Hi,

@unknownuser said:

The problem is that Sketchup doesn't store a registry key that will let you find the directories.

I don't agree: go to HKEY_CURRENT_USER/Software/Google/Sketchup6/Preferences/ and get the "Template" key. Parse the result and get rid of "Ressources/local_folder/Templates/..." and you have the path to the install dir.
OK, it assumes the user stores its templates in the default folder... but you also can get the key "ComponentBrowser" in HKEY_CURRENT_USER/Software/Google/Sketchup6/File Locations...

I've done some installer in the past (for SU2POV) and I'll check the iss again to publish it if it is of any interest, but I'm sure this is doable.

Hmm. Seems your right. Ill see if I can update the installer.

Thanks
Chris

@mike ravenwolf said:

So i decided to try and build this gyro type thing tonight more so as a goofing off/learning type project. at first i had a problem because i was nesting square rings, and didnt leave clearances. So i redid the cross section of the ring and i still find myself with a problem.

Any suggestions?

Mike

The problem is that the rings are not really rings at all. They act like solid cylinders. You cant have any holes in shapes.

If you really want a torus shaped hoop you need to build each segment of the torus and make it a convexhull. then group the lot.

@julius said:

thank you so much! i finally got what i wanted!

can i ask you one more thing? is it possible to make the cannon rotate on the blue axis with a wheel+servo joint?

I had to explode and re-group the wooden parts. It was messed up somehow.

Cannon-5.skp

@jim said:

On a side note, I've been running the idea around my brain of an installer for plugins which are only one file. It would be run from within Sketchup, could check for updates, and then backup, and download the script to the correct location.

It wouldn't be hard, except for finding/writing reliable network code might be tricky.

Thats a good idea! It would be useful even without the auto updates.

@unknownuser said:

Chris,
I am using it as well for SU2KT and haven't had problems with it.
It is highly customizable. I know it is possible to read win registry to find out SketchUp dir automatically. I haven't tried it yet.

Tomasz

It is possible for the setup to check the registry. The problem is that Sketchup doesn't store a registry key that will let you find the directories. I mentioned it to the Sketchup team and they said they would try to add something in a future version.

At least it seems most people install in the standard location.

@julius said:

so, basically, i cannot make the piston joint rotate along with the cannon and fire when i want...

The piston will rotate with the cannon. But it will fling the cannon ball as soon as you play the simulation.

Cannon-2.skp

@julius said:

So, i'm trying to build a cannon. now it rotates with a servo joint. i wonder if it's possible to throw out the ball with a piston joint after the cannon is rotated.

Thank you in advance.

A piston would certainly push the ball out. I don't know how you would trigger it tho. Maybe a hidden object that will hold it in until its in the right position.

About 90% of the feedback I got on SketchyPhysics was problems installing. "Unzip into the plugins directory" is apparently beyond a lot of average users.

So for SketchyPhysics2 I researched installers. I wont go into details but I tried several and they all had various problems. Most were either too complicated or produced flaky results.

I believe it was Jim who first pointed me to Inno Setup.
http://www.jrsoftware.org/isinfo.php

Its simple, free and pretty close to fool proof. So far with over 500 downloads of SketchyPhysics2 I have only had one user who had trouble installing. And that was because he didn't know where his browser saved the setup file.

Attached is a template installer script for Sketchup plugins. Pretty much all you have to do is a simple search and replace and specify what files to include.

1. Install Inno setup. http://www.jrsoftware.org/isdl.php
2. Run it and open the attached .iss file. Its really just a text file.
3. Search and replace "MyPlugins" with the name of your plugin.
4. In the [files] section specify which files to include in the installation.
5. Run "Compile" and you should have a setup.exe that will install your plugin.

Result is a basic standard setup program that will try to install the plugin in the correct Sketchup directories. It will warn the user if the plugins directory isn't found. And it also supports uninstall.

Hi

First of all i really like sketchy physics. I tried all the new functions in the new version and its great! Im only having one problem that i also had in the previous version. I hope i can explain what i mean because my english is not that good. If i make a box for example and cut a hole through it (with push pull function) and place this on something static, If i now make a small ball and place it in the box, it falls right through it. The only solution seems to be to make the box a static mesh, But thats just not what i want. Offcourse i can make the same "box with a hole in it" from 4 independent walls but that makes it a little complex. Can somebody help me out on this one?? Thanks in advance

Regards Maurits

Sorry Maurits, that is just the way it works. All objects must be convex or be made of convex shapes. Static mesh is special because it never moves.

The reason is; if non convex objects were to move it would make the whole thing much much slower.
