MSPhysics 1.0.3 (16 October 2017)

robint

Hi, Robin,

I just revised the spring joint to base on Hooke's law. Just need to adress a few other things before its ready for the release.

Regards,
Anton

Hi Anton

It occured to me loking at the motor joint, that it would be neat to have control sliders on important coeffs, of spring rate, friction, and damping, help to speed up student experience

BTW just seen some example in Sketchucation, blown away with the talent out there

Hope my little exercises aren' t too dull

Cheers

Robin

What am I doing wrong?

Hi, gilles,

You just need to adjust motor joint properties. So, select the motor joint, open MSPhysics UI, and set Accel to 20, Damp to 10, and uncheck the Free Rotate checkbox option. This should make the motor more stronger.

Thanks Anton,

Very nice tool you made there.

THEO.skp

Anton_S

Very clever, gilles!

I'm sure there is a way to improve performance and stiffness of that thing.

I had issues with MS UI: modifying values, sometimes works sometimes not.

Then I notice this: typing a value +enter or tab does not work.
Typing a value + click outside the input box works…

Just for anybody else having the same troubles.

Mac OSX 10.8.5, SU2015.

Yeah, I'm working on that. Thanks for the report, gilles!

Hi gilles

I don't know if this is related but i noticed that when trying to alter friction, on cursor in window an X appears on the rhs and a new input will only be accepted after mouse over click X which blanks the window for a new entry

kinda convoluted

Thanks Anton for fixing the full-screen issue my animations are back to normal
MSPhysics 0.9.9
tested on win 8.1 and sketchup 2015/2016 working fine.

the new plane joint works great on single or two different planes

thx again and merry xmas

Hello, Tez,

Good to hear that it's working now. And merry Christmas to you too!

Best regards,

Sorry Anton forgot to ask u in my last post about simple OnTouch sound scripts

in Sketchyphysics i just tick the OnTouch panel and use
playSound('Sound1')

what's the MSphysics equivalent script for Ontouch sound .....i keep getting an error?
its no bug ..just me don't understand MS scripts yet.

Hi Anton, installed 0.9.9 and restarted SU
but its screwed up my model?
It falls downwards and I cant get the static floor to work as before, also the script stopped working
Did I do a corrupt installation?

Should I have deleted 0.9.8 first - you didnt say?
I assumed it would overwrite and update itself
Where to go? delete and start fresh installation or go back to 0.9.8?

What to do?

Tez,

In the Sound tab of the MSPhysics UI, whenever a sound is added, a piece of code for playing the sounds is displayed below. For your case, after you add the sound to the MSPhysics UI, the code for playing it would be:

onTouch { |toucher, position, normal, force, speed|
  simulation.play_sound("Sound1")
}

You can also refer to this scripting documentation link for playing 3D sounds: http://www.rubydoc.info/github/AntonSynytsia/MSPhysics/master/file/Overview.md#Music___Sound

Robin,

I assume the script you talk about is the controllable sphere thingy. There has been some scripting changes and the documentation for the controllable sphere is updated. For your case, you will have to replace the add_force2 function with the add_force function.

Now, I don't know how the static floor behaved previously. Basing on the model you posted, everything is working fine. I don't see any issues.

If you want to revert to on original version, you may always refer to the instructions on the homepage.

Very strange Anton, I removed the sphere from the model to avaoid confusion , but on mine Falling block 7 the whole model falls. I must assume I got a corrupt installation, so will start again afresh back to 0.9.8 and fb 6

Cheers

I am pleased to report, that after a tedious uninstall of msp and a clean instal of 0.9.9, everything now seems to work ok

Overwriting existing files looks unwise and it was severely screwed up

I would advise users

Cheers

Robin

PS I made the block and floor out of tungsten carbide, so the block didnt penetrate AKAIK, but bounces as expected

Thanks Anton for making MSPhysics better and better. First impression of running an old model with Curvy Pistons with version 0.9.9 - all moves but some objects move backwards... - I will test in the next days what I must change to get the desired results.
Merry Christmas to all friends of SketchUp, physics and animation.
