MSPhysics 1.0.3 (16 October 2017)
-
Good news, as always.
-
The boat-car is a good example to learn the use of thrusters and joints (motor joint as a component copy).
Version 0.7.4 (May 26, 2016) has the same problem in Replay that Play, Stop and then Play again is running into problems...
Maybe it is my computer... -
The emitter test you posted in one of the earlier post works as expected. Can you elaborate more on what problems you encounter?
-
Sorry. Maybe I have the function of the stop button just now understood. I think that with the stop function the model can be held and saved in an intermediate state of the simulation. After that you should delete the replay storage, otherwise unexpected intermediate phases of the simulation arise if you start or play again.

Announcing version 0.8.0!
This version comes with many bug fixes and improvements. As well as with two new joints: CurvySlider and CurvyPiston. A demonstration of these two joints is available at 3DWarehouse: https://3dwarehouse.sketchup.com/model.html?id=d21984a9-477b-44d7-9eca-c191ae85afe4 -
The new Curvy Joints improve animation along paths fundamentally. The possibilities are not yet in sight. Great is that you can take curved sections and even edges with the joint in a group without to weld them, and therefore the curve in turn can be moved. Your examples show this excellent.
Two questions:
What are the rules for the orientation of the joints to an individual curve - exactly parallel?
It seems that old Servo Joints with Oscillator as a controller are not functioning as in version 0.7.0? Tested for example, with birdy and orca. -
Well I hopefully thought I'd try again.

the error at least looks a little different.

Hello Faust,
Curvy joint orientation has no effect on a curve or whatsoever. The curve may be parallel or not parallel to the actual joint - it doesn't affect the way joint behaves. The joint object just represents the origin of the joints. The edge closest to the origin of the joint is considered as the starting edge and all its connected edges are considered as the consequent edges. As long as the curve (or a set of connected edges/arcs) is created within the joint, with the angle between each edge set to a maximum of 45 degrees, the curvy joint will work fine. To my experience CurvyJoints operate better on iterative solver than on exact solver. So if you use curvy joints, setting a solver model to iterative 4+ passes will guarantee the optimal behavior.
The servo joint was reworked in this version. Now instead of accel and damp, it uses angular rate, and the SP Mode was removed. If your joints relied on SP Mode, their controller values ranged from 0.0 to 1.0. Now that is changed. The controller values range from -min_angle to max_angle. So for your birdy the servo controllers should be changed to something like,
oscillator(100)*30. The limits should be disabled or adjusted to -30,30.
Ralph,
Sometimes the zip file fails to extract all content. Try checking if Plugins/MSPhysics/win64/2.0/msp_lib_no_sdl.so exists.
-
Ralph, I reworked the main.rb to display more info about the loading errors.
Place in .../Plugins/MSPhysics/ folder. Overwrite the original one.
-
-
Okay that's better. Based on the message, particular files are missing from the plugin's folder. As mentioned before this could be due to extraction issues, where the zip extractor fails to extract all the files. To ensure that its not the code error, go to C:/Users/Ralph/AppData/Roaming/SketchUp/SketchUp 2015/SketchUp/Plugins/MSPhysics/win64/
and check if all of the following files are there:- libFLAC-8.dll
- libmikmod-2.dll
- libmodplug-1.dll
- libogg.dll
- libogg-0.dll
- libvorbis.dll
- libvorbis-0.dll
- libvorbisfile-3.dll
- SDL2.dll
- SDL2_mixer.dll
- smpeg2.dll
If that's not the case, try re-downloading MSPhysics and extracting using 7-zip, as it might a better alternative to the standard windows extractor. If you don't want to go through all that manual extracting and moving mess, you can instead use PluginStore plugin to download and install MSPhysics by a few clicks.
-
When I download from the PlugIn store all I get is a .rbz file not the zip file.
Does that go in the Plugins folder?
-
This is so irritating.
I cannot run 7-zip I have had it installed and have used it with Windows 8 but it does not run in Windows 10.
Win Zip apparently is not extracting all of the files specifically the win64 folder.
I can go to GitHub and see the win64 files but I do not know how to download the individual files.
-
Finally I got the win64 folder downloaded completely, I got 7-zip to work.
Now:

I am so sorry to be such a bother, I do not even know if I will understand how to use MSPhysics once I get it working it seems kinda complicated, but really neat in what I have seen.
-
I have tested the installation of MSP-Version 0.8.0 with the ExtensionStore and it does not work (Windows 8.1, SUp 16 Make). But downloading from Google Drive, unzip, delete the old MSPhysics SubDirectory and copy the new into the plugin directory works.
-
Ralph, Faust, that's bad. Installing MSPhysics via PluginStore (on SU2014 and SU2016) works just fine on mine. I think an automated installer would be the best way to for installing such plugin. I will create an installer and we'll see if it works then...
-
Ralph, I created the installer, which installs both MSPhysics and AMS Library. The link is available in first post. See if it will work after installing with the installer.

How can I change the direction of objects on a CurvyPiston Joint? Currently, connected objects move in the negative Z-direction of the joint no matter what positive ore negative number I input in the Controller ore Power fields.
-
I found the solution: a value less than the length of the curve in the Controller field makes the object follow the path backwards. What would be cool if there was some kind of infinite loop function ...
-
Birdy on the new CurvyPiston Joint. Very easy to do!
But how can I make the object following the curve more flexible and grabs not so hard around the corners?
