MSPhysics 1.0.3 (16 October 2017)

It would be good, if we could control the speed of an object that is connected to a CurvyPiston joint with slider or script.

You can do it with script. Paste this code into the object connected to a CurvePiston joint.


onStart {
  @joint = this.get_connected_joints.grep(CurvyPiston).first
}
onUpdate {
  if @joint
    @joint.rate = key('w') * 1 # some value; in this case we controll it with kry 'w'
  end
}

Here is a link to all available functions in CurvyPiston: http://www.rubydoc.info/github/AntonSynytsia/MSPhysics/MSPhysics/CurvyPiston

Ralph I suggest starting from the basics. Here is the guide: https://github.com/AntonSynytsia/MSPhysics/wiki.
Its not done yet, but progress is being made.

thanks Anton, I have not seen that menu bar.

First tests with the new renderer Indigo RT - Export Replay to SkIndigo works very well. Have only one question: How do I get emitter objects into the Indigo rendering process? These objects are not shown.

Anton_S

Faust, it's good to know that it works. I'll see if there is anything I can do to get the emitter rendering in Indigo.

Be sure to liaise with "OnoSendai" and "Whaat" for assistance...

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.

faust07

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

faust07

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.

Anton

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 ...?
