MSPhysics 1.0.3 (16 October 2017)
-
I made more models to be more opportunities.
1.) Frozen: mortar 4.1.skp
2.) Hide: mortar 4.2.skp
3.) Simulation pause: mortar 4.3.skp
And magnet test:magnet.skp

Hi PP
tried your magnet and I am baffled as to why its so very slow, <2fps. tried everything to speed it up. Sketchy physic was much faster? I made ther executive balls desktop toy by putting all the balls as pendulums in a frame and colliding. It was fast and realistic?

Even stranger, I managed to get my balls to clang together at 30 fps, but unable to simulate repulsion even with negative magnet values? I notice that perhaps magnet is a wrong term as it behave more like gravity between two masses (hence no repulsion effect)
Universal gravitation equation
F = GMm/R2where
F is the force of attraction between two objects in newtons (N) G is the Universal Gravitational Constant = 6.674*10−11 N-m2/kg2 M and m are the masses of the two objects in kilograms (kg) R is the separation in meters (m) between the objects, as measured from their centers of massnotice how the ball is attracted to the target even though the target has no magnetic force
for example

Hi PP
Got as far as 4.3 and it certainly is the cats whiskers, like the disappering effect in 4.2, all we need is a little pop up explosion (still no sound on mine?)
I dont understand what is affecting the fps so drastically? It goes from 30fps down to 4 or less

Playing with real shells. Wonder how I can get the nose pointing along the path? hmmm
notice the fps is 27, yet on some of the models its very slow 2fps
-
For me 63 fps.

Wow PP that has blown me away, havent looked into detail yet, tomorrow am
Now could this be mounted on a tank? Forward, left, right track
Then we could have two or more, multi players
Tank battle, forests, obstacles, terrain, mines, smoke etc
Pls assume all rights, I'll be your beta tester and write the manual
Robin
Ps I wrote a game like this in BASIC years ago, for four players, it was extemely addictive, hidng under tree cover trying to guess where you opponents were. Each tank had a home base corner and had to return for new ammo and fuel. we spent hours on it
I turned this into a kids game sliding around on mats on a polished wood floor blindfold, getting coded instruction from their base commanders. They fired foam tennis balls at each other and only had three reserve tanks. Couldn't get them out of the classroom, oh and they had to give their instructions in a foreign language, French German, Italian and swedish - a summer uni job - but the kids loved it

I have a little issue where sometimes when I run the sim (simple hinges) it starts scanning and objects seem to disappear. I can control the camera and see them or half of the object. But it gets worse and worst until I have to reset it. Is there any steps I can take to fix this?
-
INVR, camera clipping is very like caused by some objects falling down too far away from camera. To fix this, find the objects that fall down non stop and draw a floor below them or set them to ignore if they are not necessary for the simulation. These objects could be hidden groups or hidden layers. So uif you unhinde everything, and run simulation, you should be able to notice which objects do that.

Testing "export replay to images" in SketchUp 2017.
The result is incomplete images with always the same empty white parts..
The same happens when using the following line in a MSPhysics script:Sketchup.active_model.active_view.write_image("e;/MSPh_Temp/frame_%06d.png" % frame,1600,900,true,1.0)How should it be right for SUp 2017?

Hi, Anton. Here I have yet an other question:
It would be great if, for example, there would be a mode for the servos to hold the joint exactly at the center of rotation and completely prevent the centrifugal forces and the pulling out of the components involved.
In the enclosed example, I have not found any way to keep the outer sections of the wings exactly at the center of rotation of the servos. There always develops a gap between the parts.
Have screwed at all settings and nothing was useful.
It seems to be a kind of inertia of the outer wing segments, which can not be stopped by reducing weight, gravitation, friction, etc.

Hi Anton, is it possible to control the movement of a servo motor with a function of time. An Excel file ? In the command section can replace the slider by a function of time ( ontick ? ). ... thank you very match.
-
Yes, luckyvac, it is possible to control servo angle through a function of time. There are lots of ways it can be done. One way is to simply write a function into the controller section of the the servo. Say, you want to control the angle of the servo, in degrees, with a function f(t) = t*3 + 150.
Converting it to ruby and MSPhysics, the code would like like this:world.time * 3 + 150. If you paste this snippet into the controller section of a servo, it will have the servo angle be the value of this function at simulation time, t. -
Hello Anton,
Thank you for your reply. I will need more knowledge to carry out my project.
I am guitarist and I teach guitar accompanying songs.
This project aims to realize a tutorial to learn how to play the accompanying guitar and to show that one can realize accompaniments guitar with 5 or 6 rhythmic figures.http://www.luckyanimationspectacle.com/index.asp?pageid=33
I used MSPhysics to simulate the movement of the arm and hand of a guitarist holding a pick.
He accompanies guitar with a song following the rhythm 1-2-345et.
Fig.01 As an attachment. pierrot robo guitarI used 2 servomotors:
- one for the forearm which operates the up and down of the forearm.
- a second for the descent of the hand.
I made a stop-motion video by adjusting the two actuators point by point according to the following diagram:
Fig.02 As an attachment 1-2-345et
I would like to replace the slider by time functions, point by point (FIG. 2) or FFT.
The displacement coordinates of the servomotors are shown in the table in figure 02.
You will find the simulation with the <FOREARM> (avant bras ) and <HAND> (main ) slider in my drive and an example video. I chose the refrain of Bob Dylan's "blowin in the wind".
Here is the link :
https://drive.google.com/open?id=0B00m7nJr8D_qTnRXX3AyeWVyZmc
The video tutorial shows the synchronized movement with a rhythmic tablature made with Guitar Pro MIDI (*.gpx, *.mid ). There is no human, just my voice
.I thank you for your attention and information you can communicate to me to help me realize my project.
Best regards

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 ControllerJoystick
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
-
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
