MSPhysics 1.0.3 (16 October 2017)

TheSniper

Anton Awesome Plugin Thanks for the hard work!
I add And not to complain but hopefully to help.
Platform: Sketchup 2017 on Mac 64 bit
Known issues: 1 setting dont get saved in multiple areas for instance in the Joint and Piston Settings: Max and Min wont save always defaults back to -393.7007874, as well as the controller line resets back to default values. Controller name wont transfer over either. In the Servo panel: cannot save custom servo names, Plus Servo Max and MIn wont save either. Just some examples. Hope it helps. -S

Hello
Problem of direction axes
Xbox Controller

Joystick righty) is X-XAXIS position on right stick.???
Joystick rightx) is axes button LT.????
No axes Y-XAXIS right stick.???

please.

Great thanks Anton, I wait peacefully while working on other rhythm guitar.

Hello, I would like to know how to increase the damping of the servo motor. Thank you

Anton_S

Hi, Luckyvac,

Which of the joints are you referring to, a servo or a motor?

To increase the damping of a motor joint, simply select the desired motor joint, open MSPhysics UI, and increase the Damp parameter.

To increase the damping of a servo joint, that is decrease its angular rate, select the desired servo joint, open MSPhysics UI, and decrease the Angular Rate parameter.

Hope this helps,

Anton

@luckyvac My appologies for not responding any sooner. I am a bit busy. In short, it's possible to have the servo angle correspond to the table values at time t. The table with angles and times must be converted to a Ruby Hash and then the rest is easy. I will examine your model in depth soon and we'll see what can be done to get the guitar stringing.

@TheSniper Apparently there were a few reports about the dialog options not working properly on Mac OS X and that's not good. I will check it out soon.

@SynSuka3D The joystick function accepts four symbols and each of them correspond to an axis on one of the joysticks:
joystick(:leftx) returns X position on left stick.
joystick(:lefty) returns Y position on left stick.
joystick(:rightx) returns X position on right stick.
joystick(:righty) returns Y position on right stick.

The position ranges from -1.0 to 1.0.

Here is the documentation link to the function: http://www.rubydoc.info/github/AntonSynytsia/MSPhysics/MSPhysics/CommonContext#joystick-instance_method

I suggest you explore the MSPhysics scripting documentation for specs and other functions that might be useful, such as joybutton(button).

Hi Anton,
Thank you for your advice it works ... but ... I send you the left hand of the guitarist named "Pierrot".
I feel that the system comes into resonance when I connect several servo motors to each other.
What do you think ? How to decrease the resonance ?

Merci

have a nice week end.

@SynSuka3D Interesting, I will fix this.

Add joystick(:rightz) and joystick(:leftz) for joy(RT) and joy(LT) please.
for xbox controler.

Roger that!

Hi, SynSuka3D,

I fixed it and added rightz/leftx commands.
You can download the WIP version here: https://drive.google.com/open?id=0B3qg8f4WrNdHUmE5OXNiWjQ0Vzg

You can try out the joystick controller test model attached below.

Best regards,
Anton

Should make my question more precise:
The reason for the loose behaviour of the joints is the update rate in MSPhysics UI - Simulation - Update Rate = 1 (seems the best for my large model).
If I change this from 1 to 3, the servos remain more stable in the pivot but the spring no longer brings the steady up and down movement.
Have now tried to modify all settings at the Spring Joint, but do not get the desired result.
What can I do?
Thank you in advance, Anton!

Update Rate 1

Update Rate 3

Hi Anton and the community,
I think I have found the solution to control the damping of the servo motor. I worked on the geometry of "green" parts to decrease the sensitivity to the vibratory modes. As we can do in reality.
It's impressive !

Best regards.

Unfortunately, changing the Update Rate from 1 to 3 is not useful when camera, joints, emitter, etc. are based on scripts that use the OnUpdate function. Programmed objects become 3 times faster. The appearance of emitted objects no longer fits to the image rate. The weight of the emitted objects or the lifetime seems to change.
For the joints based on pivot points, an option independent of the Update Rate in the user interface seems to be useful for fixing at the pivot point. If this is possible...

@Anton_S goood xbox controller Merci!

@Anton_S
@body.set_omega([Internal body axis , 0, axes in global space]) ???

ex:
*onStart{
@body = simulation.find_body_by_name('body')
}

onUpdate{
r_body = @body.get_matrix

ax = Geom::Vector3d.new([key('up'), 0, 0]).transform(r_body)

@body.set_omega([ax.x, 0, key('right')])
}*

Anton,
Got the update, (Thank you) I have not gone thru all the settings as of yet. But so far it appears to working as expected. Ill let you know as soon as I can get thru all the settings THANKS! -S

Anton_S

SynSuka3d, like I said, you should reference the scripting documentation to see what each function does: http://www.rubydoc.info/github/AntonSynytsia/MSPhysics/MSPhysics/Body#set_omega-instance_method
