@Anton: cool new MSPhysics models in 3D-Warehouse - you linked in the first post
Magnets test, copyable joints, new turret with missiles, buoyancy with flow on water surface ... - impressive!

Can we have an option to store Replay in a model, please?

And from Anton's TODO list - the fracture/split function and Twilight implementation.

Hey everyone, first post here. I have MSPhysics 0.4.0, and I have a model which I would like to use in a physics simulation. The model is a box with several protrusions and a few holes. When I run the simulation with show collision meshes enabled, the box's mesh is rendered as a box with all the empty spaces included, so objects hit the spaces between the protrusions instead of continuing through. Any help would be much appreciated!

I speak French
Excuse me my english
I want a body designated by name ? Please
I TEST get_"group_by_name(name) Does not work !!!
ex: skechiphysics FindBodyName(NAME)...

SynSuka3D

findBody("name") and findGroupByName("name") ==> version MSPhysics ????, please.

Not knowing what I am doing I cannot get a good install!!

@Ralph

The file:
C:/Users/Ralph/AppData/Roaming/SketchUp/SketchUp 2015/SketchUp/Plugins/MSPhysics/win64/2.0/msp_lib.so
I not being found.
I a proper installation it should be there.
How did you install the files and subfolders ?
Did you install the contents of both of the required ZIP files, keep the subfolder structure entirely as it is in the ZIP ?

Do you actually have the missing file installed ?
Open the Plugins folder and have a look...
C:/Users/Ralph/AppData/Roaming/SketchUp/SketchUp 2015/SketchUp/Plugins

Compare the ZIP file's contents with what's in Plugins...
All files are needed...

Ralphxyz

Thanks TIG, C:/Users/Ralph/AppData/Roaming/SketchUp/SketchUp 2015/SketchUp/Plugins/MSPhysics/win64/2.0/msp_lib.so is there!!

There was no "installation" I just downloaded the zip file, unzipped and copied to the Plugins folder.

The "missing" file msp_lib.so is the MSPhysics\win64\2.0 folder.

I'll try again this time un zipping directly to the plugins folder possible something was missed with the copy paste but the reported missing file is there.

What windows version and sketchup are you using, Ralphxyz?

Ralphxyz

Windows 10 SketchUp 15 Pro

SynSuka3D here are various ways to get bodies and groups in MSPhysics:

body = simulation.get_body_by_name(name)
body = simulation.get_body_by_group(group)
group = simulation.get_group_by_name(name)
group = this.get_group # get group by body

See extended docs here: http://www.rubydoc.info/github/AntonSynytsia/MSPhysics/MSPhysics/Simulation

Ralphxyz, it works on mine. It strange that it doesn't work on yours. Can you open MSPhysics/main.rb and uncomment #UI.messagebox info, on line 21. After you start SU a messagebox box should display with a list of libraries and their loaded IDs. Then post the library names that have their IDs set to zero if there's any. The ID of zero indicates that library failed to load.

Ralphxyz

"Error Loading File MSPhysics/main.rb
Could not find included file 'MSPhysics/main.rb'

I have main.rb in both MSPhysics folders but it is not found!!

Anton_S

Hey Ralphxyz,

Okay, first of all, did you extract MSPhysics_0.7.0 into the plugins folder properly? You said you have main.rb in both MSPhysics folders, what do you mean by both? There should be only one MSPhysics folder in the plugins folder. And that one folder should be named "MSPhysics". Refer to the first post of this thread to see how the MSPhysics related content in the plugins folder should look. Please elaborate more if I misunderstood.

Now, the error you just posted might also mean that you didn't uncomment the requested line in main.rb properly. Here is the main.rb file with the uncommented line. Place and overwrite the original file that is located in ../Plugins/MSPhysics/ folder. After you start Sketchup, a messagebox should appear listing all library names and their IDs. I would like you to post me at the forums which libraries appear with a zero ID (if any).

Ralphxyz

Thanks for the replies

re: two MSPhysics:
C:\Users\Ralph\AppData\Roaming\SketchUp\SketchUp 2015\SketchUp\Plugins\MSPhysic

C:\Users\Ralph\AppData\Roaming\SketchUp\SketchUp 2015\SketchUp\Plugins\MSPhysic\RubyExtension\MSPhysics

did you extract MSPhysics_0.7.0 into the plugins folder properly? I "think" that is the problem.

Anton_S

Yep, the files are extracted incorrectly.

If you downloaded from github, only the files within the RubyExtension folder should be placed into the plugins folder. The rest are not necessary. In fact downloading from github is not necessary at all. You can download from the first post of this thread instead as it only contains the necessary files.

Once you download, place MSPhysics folder and MSPhysics.rb into the Plugins folder. It should be:
C:\Users[SomeUser]\AppData\Roaming\SketchUp\SketchUp 2015\SketchUp\Plugins\MSPhysics/
C:\Users[SomeUser]\AppData\Roaming\SketchUp\SketchUp 2015\SketchUp\Plugins\MSPhysics.rb

If that's not clear I guess a series of images or a video would be a better alternative for describing how to download plugins...

Ralphxyz

I downloaded from your reference once again and unzipped directly to the plugins folder.

Now:

Anton_S

The extracted path is correct now. The error suggests that your system is missing certain libraries that MSPhysics relies on. I had a few reports similar to yours and I can't figure out what is causing the load error. The only thing that comes to mind is checking whether all other libraries, that msp_lib.so relies on, load properly. To do that, I want you to download main.rb in this post and place it into MSphysics folder, press 'yes' to overwrite the original file. When you start Sketchup, a messagebox will appear listing loaded libraries with their corresponding identifiers. Before pressing "Ok", I want you to see if there are any libraries that have their identifiers set to zero. If there are, please list their names here at the forums so that I could attempt to make them compatible on your system.

Hello Anton !!!
I am not an advanced user of MS Physics and SketchyPhysics in the sense that I do not use a code script(one reason is that because I do not really understand how to use it...), but I've used both almost from the beginning...
And I want to say that you did a great job with both !! Thank you very much !

I really like to use all objects as they are like in the real world ...but ..

I have a problem with frozen objects..

I noticed that if an object falls near a frozen one the seccond will fall without being touched...

and ...
how to use emitter objects? I do not understand the definition on how to use these objects ... how to increase their life ? I have to use a code script? I'd like a box where you specify this ..
Thank you !!!

Thanks again for the help!! Oh I am using Windows 10.

Sorry for the delay in answering I do not use this computer everyday.
