MSPhysics 1.0.3 (16 October 2017)

Dalton325

Is there a manual for MSPhysics? For now, I'm just trying to make a simple animation with hinges, and it's doing all kinds of crazy things. I've found a couple of solutions through trial and error, but I'd love an instruction manual. Thanks.

Regarding rendering of MSPhysics animations: After further tests with Indigo is clear, the definition of new materials in MSPhysics scripts leads to termination of the rendering start and an error is indicated (test with MIDI-Studio, AntonS).
Color changes of objects in scripts are not shown when rendering (test with Animated_colors, PituPhysics).

@Juju, thanks. I'll contact these guys if I get stcuck on something.

@Dalton I made a few beginner videos on using joints. They are not the best, but better than nothing. Here are the links: https://github.com/AntonSynytsia/MSPhysics/wiki/Using-Joints

@Faust Thanks for another report. I'll check it all out.

MALAISE

It sounds well. Could someone explain how to " associate" curvy joint and a curve ?

Cheers

Hi Malaise,
I just completed a tutorial on curvy joints. Here it is:

Very fluid!

MALAISE

You've done a really good tutorial. Many thanks for sharing.

faust07

I just found the way in MSP-Context-Menu to give copied joints their unique Identity - "Make Unique ID". This makes the reproduction of complex MSPhysics objects much easier. And is another great advantage.

Hallo Faust07

Could you post a "printscreen"?  Grüss

I have copied a few birdies and it looks good, not to have to set up the joints again. However, Joint Connections need to be updated manually.

Hi Anton: "Small modest" request for a script: Daughter Your ingenious SketchyPhysics model with script - WAVES. I'd like to have a script for a surface (floor surface, water surface, etc.), which gives information on the location at which point an object penetrates this at a certain speed. At this point, should a particular event happen -. E.g. emit a cloud of dust ... Don't know if this is in MSphysics possible.

faust07

Two more detailed questions about the above topic regarding onTouch: How can I get the absolute coordinates of the point (x, y, z), there a falling object is touching a flat (square) face first? And how can I get the amount of the force of that impact? Thanks!
Sorry, already found it in Your script examples "Touch Events" (first post..).

Anton_S

Hi faust,

Assigning unique IDs is one way to manage copied joints. Another way, a more preferable one, is by selecting the whole birdy, with its components, and clicking (Context Menu)->MSPhysics->State->Connect Closest Joints. After that, you can copy the birdy multiple times without having to assign unique IDs.

It is possible to create waves and splash effects with MSPhysics, however, just like in SketchyPhysics, there won't be much physics involved; most of it would be controlled through scripting. That said, the touch events won't respond to the bodies contacting the "artificial" waves. This will require writing additional code for determining contacts and then emitting dust or splash effects at such points. All in all what your asking for might require quite a lot of coding and I'll have to pass on that one. You can however try utilizing it yourself maybe with workarounds and simpler approaches.

The Connect Closet Joints - method sounds great. Will try it. Thanks!
I hope that your last sentences were based only on the coding of specials like waves and not generally on to the development of MSPhysics ...?

Announcing 0.9.0!

Compatibility with Mac OS X 10.5+; still limited when it comes to managing keyboard, mouse, and MIDI, but the most important stuff is working just fine.
Fixed a bug where MSPhysics failed to load previous editor settings. Thanks to PituPhysics for report.
Joystick should work even if connected after SketchUp starts.
Added alignment power option to CurvySlider and CurvyPiston joints.
Added LinearGear, AngularGear, and RackAndPinion constraints.
Reworked the scripting API. Various functions were renamed and rearranged.
Renamed various ( get_some_method/ set_some_method) functions, that acquired one parameter, to some_method/ some_method=.
Added BodyContext class. All body events, such as onUpdate, were moved to the BodyContext.
To reference a Body associated with the BodyContext, call BodyContext.#this.
To reference a BodyContext associated with the Body, call Body.#context.
Renamed Common and Controller to CommonContext and ControllerContext.
Scripting scope was changed to BodyContext. To call body methods from the scripting scope, it is now essential to place the keyword "this" in front.
To call BodyContext methods, which are mostly events, from the scripting scope, you don't need to place any keywords in front.
Renamed get_body_by_group, get_group_by_name, etc.. to [ruby:15odxhy4]find_body_by_group[/ruby:15odxhy4], [ruby:15odxhy4]find_by_by_name[/ruby:15odxhy4], etc...
Renamed all [ruby:15odxhy4]is_some_method?[/ruby:15odxhy4] functions to [ruby:15odxhy4]some_method?[/ruby:15odxhy4].
Many methods that focused on general stuff were moved to AMS Library. For instance, the whole [ruby:15odxhy4]Group[/ruby:15odxhy4] and [ruby:15odxhy4]Geometry[/ruby:15odxhy4] classes were transferred to AMS Library.
The scripting changes were made for coding convenience and are very likely to remain unchanged in the upcoming releases.
Enchanted control panel and the dialog.
Various other bug fixes and improvements.

How process (if possible) for have and keep the tracks marks of the car moving on the terrain ?
(of each wheel)

faust07

In my case (update from MSPhysics v0.8.0 to v.0.9.0) using the Extension Store leads to immediate failure after start of MSP (also with the new models). It seems that old files in the MSPhysics folder of v.0.8.0 partially are not deleted or overwritten. To delete the directory and copy it complete new in the plugin folder works.

faust07

After revising the scripts for v0.9.0 my test models work better than before. To record simulation to Replay is much faster too. Thanks!

faust07

The option to save the replay data in the model file has been lost ...?

Anton_S

Pilou, it's possible to create tracks, but only through scripting.

Faust, my bad. I disabled the saving of Replay animation into model because it affected performance; that's why you noticed huge performance boost in this version. I was trying to rework it, but then completely forgot about it. The fix is underway.
