Thanks! That should be enough to get me started. Is there a "master list" somewhere in my file I could look at to check if my variables, joint names, etc. are being recorded correctly. I have had some trouble with UI sliders not showing up when they should, joints misbehaving, and so forth.

I have a 10.4 intel mac, and for me SketchyPhysics crashes frequently enough that I make sure to save after every change I make. The more complex the model, the more likely to crash. It's really frustrating sometimes, but it does play simulations usually.

Now that you have installed SketchUp, use the following link to view the latest SketchyPhysics downloads...
http://code.google.com/p/sketchyphysics2/downloads/list?can=1&q=&sort=-uploaded&colspec=Filename%20Summary%20Uploaded%20Size%20DownloadCount
Again, run it, and follow the on screen prompts. It will install itself in the SketchUp Plugins folder.

This is just for windows, right? Because SketchyPhysics never installed itself on my mac. I finally figured it out, but some more info on how to install would be appreciated. For mac users that are reading this: Put the downloaded, extracted files in this folder: username/Library/Application Support/Google Sketchup 7/Sketchup/plugins.

I had to create the plugins folder because it wasn't there. Then I got another bug, "Error Loading File SketchyPhysics.rb
undefined method `file_loaded?' for main:Object"

I found many references to this bug, but no answers, until I found this tip from fernandogalin on the issues page (http://code.google.com/p/sketchyphysics/issues/detail?id=9

• copy sketchup.rb from Tools folder to Plugins folder
• edit sketchyphysics.rb from Plugins folder and add this line at the begining of the
  file: load "sketchup.rb"

This solved my problem and now I can use SketchyPhysics, which I love! This is the awesomest plugin ever. Hopefully this info will save some others from going through the same confusion that I did, so they can get to the good part.

Hi, I am new to SketchyPhysics. I have seen several topics on this board that have bits of ruby code in them. I was wondering, is there a tutorial for using code in SketchyPhysics somewhere? I have taken a few programming classes, and am pretty good at figuring things out, but none of the examples I've seen make sense to me yet. Thanks!
