SketchyPhysics 3x June 27 version.

CPhillips

Here is an example of a very simple camera system.

The first example puts the camera eye at the position of the sphere and looking at [0,0,0].

The second example finds the cone in the scene and looks at that. Note you can drag the cone and the camera will follow.

The @simulation.camera.set commands parameters are location of the eye, the target and the "up" direction.

The camera is the same as the camera in the Sketchup API:

Now we can create multi-roll games!

JaViXP it will work better if you change the onend to this:

onend{
>    group.erase!

Thanks, now it's much better (After a few times playing the animation it becomes kinda slow).

PhysicsGuy, well done I like your boxes creator, but there are too much boxes and it'll make the simulation laggy.

phy

MAN! That camera is unbelievablly good.

JaViXP

It does not work for me

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 )

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()

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!
