SketchyPhysics 3.5.6 (26 January 2015)
-
Okay, I reverted some replay changes. Please test with LightUp and Skindigo. Tell me how it goes.
Edit: Link removed. Download from top. -
Okay, I fixed it. Although current version of Indigo has a little bug.
Keep in mind SkIndigo 3.6.28.3 has a little bug. Please follow these steps to fix it:- Open Plugins/skindigo/AnimationExport.rb.
- Scroll down to line 369 and replace
mb.build_active_mesh(ents)withmb.build_active_mesh(ents, {}) - Save file and you're good to go.
I reported an error to SkIndigo support.
Download latest version from top.
I also finished a little SP script reference doc : http://sketchyphysics.wikia.com/wiki/Script_Overview
-
I've searched for that line in the current version 3.8.9.1 but the line (406) is marked as a comment...
-
I was speaking of 3.6.28.3 (as it shows up on SkIndigo website), but downloading the latest version 3.8.9.1 I find there a different bug, even if I try exporting from old SP versions. These guys need to test things before they upload it...
I will send an error message to them for this version as well. Yet, I can't fix it, as there are too much errors. Use version 3.6.28.3 with the fix I provided in the first post. Otherwise, you'll have to wait till they fix it.

Hi,
As Pilou says, the playback works, but running the Physics while in LightUp no longer works which is a pity.
Its not that LU is not picking up the changes in transforms - its that SP appears to terminate TourTool now - whereas before it didn't touch the current selected Tool.
Does that ring any bells in the changes you've made recently?
Adam

You're a genius, Anton! You should consider collaborating with the guys from Indigo/Skindigo
-
@Adam All SketchyPhysics3 versions used a select_tool when simulation start, which terminates all other running tools. If you don't think so, you can download SP3.2 (the official release) on SU8 for instance and see it yourself. Start lightup and press physics toggle play button. LightUp will reset...
Use SP Replay as it was made for such purpose, I think. I don't know why you were assuming SP toggle play button worked with LightUp as it never worked with any versions of SP3. Maybe because SP1 or SP2 worked that way, I don't know.
Edit: Mayby I'm starting LightUp wrong, or I have to do it the other way around. If so, please explain how.

First of all I want to thank you, Anton, for this great update! Finally someone who takes care of this awesome plugin.
I don't remember if previous versions of SP also showed this behaviour: Positive values for the blue axis (e.g. a piston slider) move things down, in negative direction, whereas positiv values for the green or red axis move things in positiv direction. This irritates me. A bug?
The other issue I want to address are units. I always use metric units but SP converts them in imperial. For instance, when I position a piston and give it a length of 100 mm (by typing 100 a hitting enter while drawing) the UI max box shows a value of 3.93... which are inches. When I type 100 into the max field, the piston moves 100 inches, not millimeter. I would appreciate it a lot if SP used the units as set in the model settings window. Actually all boxes in the UI should be labeled with the unit expected (the unit set in the model settings). For example, what's the unit of density? What's the angle unit? Radian or degree? And Strength? This would make things a lot easier.

Can you show an example, I can't reproduce this.

I can't change it because it could break compatibility with prior models, but I can make it to evaluate everything in the control box. For example, if you write 100mm it will turn it to 3.93.
Hinge min max values are in degrees. Density and strength is undetermined, it very complicated as SP bases everything on world scale. The default world scale is 9. This means all objects are assumed 9 times bigger or smaller (i cant recall), which as of results yields different volume, and mass. The volume is assumed in inches, thus the mass should be in volume_in_inches*density, where density depends on user input. Stuff are relative in SP.

This is such awesome news! Can't wait to dig into it!

A new version is out and the changelog says: "Fixing up SketchPhysics export" (not tested).

I'm sorry about that, it seems I didn't try enough. There is no difference between the axes. It irritated me that the moving direction of a piston or slider is opposite to the direction I choose with the mouse when positioning. For example, if I put a slider joint on the corner of a box and drag the mouse to the positive green direction it will move only to the negative direction.

Maybe this would help a little bit. To put the units besides the input boxes would be great and help people also. Maybe you know that a Mars orbiter crashed in 1999 due to falsely used units. I assume no one uses SP to constructed actually flying space ships, still it feels good to know what units one uses.
I found this thread which gives some information about units in SP:
http://sketchucation.com/forums/viewtopic.php?f=61%26amp;t=53209A world scale factor of 1.0 and gravity of 9.81 (m/s²) seems to be suitable if using metric units.
Maybe this thread is of interest for you also. Looks like SP's author asked this question:
http://newtondynamics.com/forum/viewtopic.php?f=9%26amp;t=4684 -
To make the mouse control desired, simply multiply the whole controller by a negative sign.
I will add a list-box from which you could choose the type of limits angle/length.

Cheers!
It exports without problems, although the error comes when try to run the exported animation in Indigo render 3.6.28. Maybe I should download Indigo 3.8.x which is not available yet?

Hi there! I've been an on and off user of sketchyphysics since 2.0.
Would it be possible to create a way to get an emitted object's lifetime? I know about the setLifetime function, but is there a similar "getLifetime?"
-
Hello, William!
Yes, SP doesn't have these methods. The API is quite incomplete.
I just added getLifetime, getLifeStart, and getLifeEnd.Is there any other getter or setter functions you think shall be added before I post an update? Sorry, I can't think of any myself.
-
You're a champ Anton, your efforts are very much appreciated.
Wish I had time to get back to some of the SP work I was doing earlier.
If anyone wants SP inspiration, check this model out: https://3dwarehouse.sketchup.com/model.html?id=5b618d4ba6c22ca85fd35d52fb19ea9b
In fact, all of Phonic's work is pretty amazing: https://3dwarehouse.sketchup.com/user.html?id=0127263341868366760323686

Thanks, Ash.
Lately, I haven't created any SP either. I suppose, that is because I kinda lost passion in it.
Phoenix is a good SP modeler. He's sharing some great stuff!
Mr.K made some amazing things too. For instance, take a look at the Blue vs Red. You control the bot to get across the puzzle. It may appear mind boggling at first, but you'll get it mastered after some experience.
-
Have you had any interaction with Phonic? I couldn't get a response when I tried some years ago - I wondered if he was only mandarin speaking.
