SketchyPhysics 3x June 27 version.

Wacov

It's only half-SP related, but how do you move the ends of a script-created line using script? I've given up trying to replace existing lines on-the-fly, I figure it'd be easier to make them at the beginning of the simulation (or, if possible, before it), then move them every frame. They'd just be there to hold the faces for cloth, and something else I've got planned

EDIT: Figured it out! Took alot of searching around, the API documentation isn't all that helpful
I'm SURE this one's overcomplicated, but it's the only way I could find.

EDIT: Hopefully, I've fixed the problem

Should work now

Wacov

That's wierd, but it should be fixed now.

phy

Awesome

JaViXP

Thanks it worked now. I have to agree with Phy, AWESOME!!

CPhillips

Here is a script that makes a simple to use auto connecting joint. In the first frame. The "pin" object automatically connects to any "door"'s it is touching with a hinge and anything else with a fixed joint. What makes it really useful is it copyable.

Note I made the "pin" object very dense and no collide. It didn't work very well otherwise.

Wacov

Thanks for the tips Chris. Here's some movable, breakable objects (Kinda laggy, but fun )

Breakables.skp

Breakable wall.skp

JaViXP

Well done I like it!

So, Chris, any new features we missed?

Wacov

Took quite a while to code this right, and I can't get the faces to smooth, but here it is! Seamless cloth!!

(Although it's not copyable)

phy

Um, CPillips how do you use the breakit command or is it a command. I don't mean the split command by the way. Wacov that's fantastic.

Wacov

I'm on a roll...

Turns out you CAN reset the simulation from within the script. Use this little chunk of code:

@@bPause=true
SketchyPhysicsClient;;physicsReset()
MSketchyPhysics3;;closeControlPanel()
freeDirectInput()

In the scripted field.

I found this near the bottom of SketchyPhysicsTool.rb, it seems to work totally normally for me, but if there's a problem, there's not much I can do about it

JaViXP

That sounds cool! I can't try this though, it displays an error

By the way, is there a way to stop the simulation and save it as the model? I mean, you are running the simulation with a breakable box, the box is broken, can you copy the model and paste into other model? (Sorry, my English is hard to understand )

phy

It doesn't work for me ether wacov I get this error, taken from the ruby console:

String doesn't compile; Error in Script&#058;
@@bPause=true

SketchyPhysicsClient;;physicsReset()

MSketchyPhysics3;;closeControlPanel()

freeDirectInput()
(eval);4;in `initEvents'; undefined method `freeDirectInput' for #<MSketchyPhysics3;;SP3xBodyContext;0x5dd6378>#<RuntimeError; Error in Script&#058;

C;/Program Files/Google/Google SketchUp/Plugins/SketchyPhysics3/ControllerCommands.rb;966;in `initEvents'

and Javi just pause the simulation and save the model.

Well, there is a lot that is still possible. I haven't seen anyone using teleport yet. Nor getVelocity/setVelocity, getTorque/setTourque or setLinearDamping/setAngularDamping. Any script connected joint can also be disconnected but I dont know a good example for that. Also the scripted code area will take tabs now. That makes it easier to write readable script.

I am not sure that will work correctly in all cases. Ill try to add something official.

Very impressive Wacov!

"breakit" is an internal command called by "split". If you want to break an object into more than 2 pieces use this:


split(self,2)

The "2" means split twice, so you'll get 4 pieces. If you use 3 you will get 16 pieces. 4=256. So dont go nuts. Also remember Sketchup will sometimes crash when you split. The more splits the more likely this is to happen.

CPhillips

I was going to do an example for split, but it turns out there are some more bugs with it. It wont work in "onstart" for example. use this instead:

ontick{
   if(frame==1)
      split(self,2)#break into 4 pieces 
      ontick{} #disable ontick
   end
}

phy

Okay thanks.

Wacov

Got cloth smoothing working, and made it easier to change the scripting (everything's in the floor). Chris, it seems if there's a script error in onend, objects fail to move back to their starting positions... and it can't be undone Try sticking jargon in onend, and see for yourself.

Anyway, the updated cloth!

Thanks. I fixed it.
