      I shared emails with Chris the other day and he and I both agree its time to get the original source code for the libraries out into the community. (Chris really did all the work and created SP, I just did the port to OS X).

      Despite our best intentions, we will never pick up the threads and get SP going as fast as Anton and you (the rest of the passionate SP community) are doing.

      What is the preferred method you'd like for getting the source code into the hands of the community?

      For those that are confused by this - I'm not talking about the Ruby code. I'm referring to the C code in the extension libraries that hook the SP ruby code into the Newton physics library and other assorted Ruby C Extensions that access OS specific functionality and other libraries (like SDL, Midi support, etc...).

        Thankyou very much Anton, it's all there now. I'll play with it a bit later (only just got up). As you been discussing, this needs to put out there for the wider community.

          Very well!

          I think GitHub is the best way to share source to the community.

            Is there a way to make control panel pop up elsewhere than in the middle of the screen?

              Could you look at changing the opening state of the toolbars.
              If you have it loaded they will always open on startup whether you closed them last time or not.

              @Gilles Might be different on the Mac, but I moved it aside and it now always opens where I moved it.

                This does not work on my mac 😠

                  Any Idea when a Sketchup 2015 X64 Sketchyphysics version will be available?

                    It won't be available until people owning C++ source of SketchyPhysics decide to release 64bit compatible libraries that are used by SketchyPhysics.

                        Please excuse me, if I did not lern my English very well.

                        SketchyPhysics gives wings.

                        Above is my sample file. My question is: How can I stabilize the joints so that they don't tremble so strong?

                        Maybe someone can set the parameters in the pattern file or give little hints.

                        Many greetings

                          It says I'm not authorized to download the file. Looks like you have to upload the attachment the other way, in the Upload attachment tab when you post a reply.

                          Meanwhile, to reduce joint flexibility, both bodies the parent and child have to have an identical mass. That is easy to set.

                          1. Select parent body, open control panel, and enable the scripted checkbox.
                          2. In the scripted field write,
                          onStart {
                            this.setMass(1.0)
                          }
                          
                          1. Do same for the child body.

                          You can change the 1.0 to any desired value. As long the values of parent and child bodies are not way off, the joint should remain strong.

                          Here is the video demonstration:
                          https://www.youtube.com/watch?v=qw2C9goxbNk%26amp;list=UUFRTk8PFA2D36yHxwYrulIw
                          Move timestep to 1:20 for visual instruction on how to set identical mass.

                            According to Newton Dynamics, it's impossible to make newton joints 100% stiff. So, your model might end up in such situation. However, you can increase joint damp parameter to 100. It will reduce angular speed.
                            Here is the fixed model:

                              No problem 😄
                              Your right, you only had to increase damp of the servo joint.

                                Dear Anton, thank you very much. I did try to increase damp, but not only at first joint with slider, but also the three joints more without slider.
                                Your file is only first joint with damp 100. And it runs well.

                                Thank you, that I could learn much.

                                SketchUp and SketchyPhysics are wonderfull tools!

                                  In my model the parts are like in real life in millimeters. For example 11 x 100 x 2 mm.
                                  When I create the Physics joints, they are too big. They cover the view to the model.

                                  In this case I have 4 joints. The distance between two joints are about 18 millimeters.

                                  How can I adjust the size of Physics joints proper?

                                    They are components, so you can just scale them as normal.
                                    Use the corner handle and crtl to scale around center.
                                    You can type in a percentage or size if you want.
                                    And you can turn them on and off using layers, sometimes it's handy to have them big so you can see what you are doing.

                                        I am using SU2014 on a MAC
                                        How do I install SketchyPhysics?
                                        Downloaded it, went to preferences/extensions..... but cannot install.

                                        Seems like other have had this issue but i couldn't find an answer for MAC.
                                        Tried SU2013 as well but same problem.Please help!

                                        Thanks

                                        Eric

                                          Hello, I installed Sketchy Physics via the auto-install into 2013 version SU. Problem I am having is when clicking the play button, SU crashes. I have removed the Sketchy Physics from the plugin folder application support/sketchup/plugins and re-downloaded the plugin. It still crashes when clicking the play button. Appreciate some help on this. I can provide the "crash report" that appears which offers an option to be forwarded on to APPLE (as if they really care) LOL.
                                          Thanks

                                            Greetings & Happy New Year,
                                            I have installed Sketchy Physics via the auto install feature and there was no problem. Opened SU 2013 and the tools were there. My problem is that upon clicking the play button, briefly the control panel appears,then SU crashes.Has anyone else had this issue? I can provide the crash log that appear on the screen if that would help.

                                            Thanks
                                            Tom
