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.
Nope, I haven't. I doubt that Phoenix even reads the comments. Usually people respond to their comments by updating the model description with responses, but I never seen him do that.

One thing with Sketchyphysics I did wonder about - and I have no idea how to execute it - would be a "Cut" function. I have modeled saw milling machinery with SP in the past but always had to do some variation of a breakable joint to simulate cutting - due to the physical reactions in breaking a joint, you can understand that it wasn't pretty.
Any idea how to cut an object so that it becomes two?
-
Piece of cake!
Copy this piece of code into the scripted field of the body that you want to be cut:
onTouch { split(self, 2) }
What happens is that it splits when it is touched by another body. Increasing the value will create more cuts.
Of course, the code may be changed to have the body be split in another occasion, for instance when it touches a particular body, or at specified frame... If you provide some instructions I could easily write you a code.
Here is a little example:cut_body_example.skp
-
Very cool!
I think I've seen some reference to this before.
How would I control the cut so it occurs in a specific place?
For example, on a piece of wood - to only be cut where the saw touches it?

SP doesn't have this method, but I created my own.

Anton,
I am stunned
I have tried so long to get a working function like what you've shown and have failed miserably - this is totally amazing. I hope you don't mind me pillaging your code for ideas?

For some reason "Hidden Geometry" is getting turned on when I run an simulation the first time. Go >View>Hidden Geometry to turn it off.
-
Cool function!
But seems there is a glitch!When I use these 2 menus!
After the Record Animation, replay etc...
Animation is stopped at the moment of the box must be "exploded" on the inclined plane!
Can you verify this ?And also the white cross texture box "transparent" who is drawn!
This is the image of the result wished!

Thx

Can you verify this ?The animation doesn't handle added and removed objects during simulation.
What happens behind the scenes:
When the body is about to be split, the body itself doesn't split, but rather two other bodies are added in similar form. The original body becomes hidden and set static, meanwhile the two added bodies take over the scene. When simulation resets the original body is unhidden, and the added split bodies are deleted. The animation tool is not complex. It does not record added and removed bodies during simulation. -

Thanks! I'd be impressed to see someone use my code

Ok!
So, how do save the result of the normal result if you want to use it for something?
For example I want use the brocken rocks for an exposition!
Now as soon has i want select them (broken rocks) the animation restart at the beginning!In the past I was making that without problem!
-
In the past when you selected a different tool SP didn't always deactivate properly, i.e. sometimes objects failed to be placed back to original locations, but now they do. I suppose, you relied on the bug.
One way to get all the split bodies is by playing simulation, pausing it at desired frame (i.e when you have broken rocks), and then save as another model. Open the new model, and you have the broken rocks!

*Anton , can you help.?
I cant get SP 3.5.2 to install on Windows 7, using Sketchup Pro 2014.
Can you advise how to do it.?
I have downloaded the .rbz file, but where do you put it SU2014 does not seem to use rbz files anymore.
Thanks,
Len -

LenThere are two ways you can do it:
Way one:
- Download SketchyPhysics_3.5.2.rbz
- Open SU2014 and navigate to (Menu) Window > Preferences.
- In the preferences window navigate to Extensions tab and select Install Extension... button
- From there, find your downloaded compressed file, and select open button, which will install the extension.
Way two:
Use PluginStore extension. Follow installation steps here: http://sketchucation.com/resources/plugin-store-download -

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.
Sorry for taking so long to get back to you. Thank you for the info!
-
Oh, actually I did think of something else that I would like to see:
Could you create a function which would allow you to retrieve the "parent" of an emitted object? (eg, toucher.getEmitter?)

I must miss something!

So the animation can never play after the beginning of the cutting!
Try with this example and show me how you can save the broken rocks.
(I have the last version 3.52)

Pilou, I'm speaking about the simulation tool, not animation tool. Press the Physics Toggle Play button and wait till the body is cut. As soon as it cuts, press the Physics Toggle Play button once again to pause. From there on you can 'save as' the model, but don't press the reset button, until you do say the model as another model, for instance, cut2.skp

Alas it's that I make but when i Reload the "save as" that is again the start of the simulation!!!
idem with your Cut2 file !
A very vicious thing!
