SketchyPhysics 3x June 27 version.

NorviewsVeteran

Sorry I don't have much to add, but there are a few things. I'm no programmer, I'm on the mechanical team.

You guys are blowing my mind. Wacov, when I opened your cloth file my jaw dropped for so long I almost drooled on my cat.

Can we upload with this version if we don't use the new features?

I needed an excuse to upload the Gopher.

Nice model!

NorviewsVeteran

Thank you, have another.

I figured out the scripted joints (big for me) to the point where I used universal joints for the bogies and you can copy more cars to the train, but the problem is I had to daisychain the joints under the cars so much the sag makes the cars lean in turns. Just beware of derails, they seem to be quite frequent...

If anyone can figure out a way around this, that would be great.

I think it is possible to set events externally with this version. I know the the syntax is a bit weird and I plan to clean it up.

Create a good sized cone and put this in its scripted field.

b=copy
> b._setEvent("ontick",
> <<CODE
>    push([0,0,1])#go forward
>    if(frame>50)
>       destroy #die after 50.
>    end
> CODE

The cone will copy itself and then set the "ontick" event in the copy.

I tried to make an example that uses "ontouch" but it didnt work for some reason. I will have to debug it.

It totally crashes my SU when I try it in ontouch, and freezes the sim in ontick... also, I can't drag the original object. It highlights, and the drag line appears, but no movement

Err... looks like you didn't try it in the right field.

Wacov

I mean ontick/touch as in:

ontick{
...
}

Try it, see what you get.

CPhillips

I am not 100% sure that works in this version. It may depend on some unreleased code. Can anyone confirm it works?

Physicsguy1

It works for me.

JaViXP

Same for me.

Wacov

It works for me, just not in any events.

Not sure I understand. Can you post a model that fails and I will take a look.

Physicsguy1

BTW,(this may be a stupid question), but is there a way around the camera 'bending' situation where the camera eye overshots to some other point3D? I cant get any reliable camera systems...

In Jun 27, putting your code inside a normal event (ontick{...}) crashes. It seems to work in the SVN version, though

Hi, just to share 2 small animations done with SkPh-3.
One is quite amusing, showing Emitter, Thruster and magnet

the other shows pseudo-virus

Got cloth smoothing working, and made it easier to change the scripting (everything's in the floor).

Ok I give up. Wacov, I just cannot see how this works. I have tried a few times. Refreshed my SkPh knowledge. Had fun with the new features.
But your cloths are a vast mystery to me.
The SkPh UI shows nothing.
Is it PC only ? Scripting only ?

Wacov

Basically, there's a physics object at the vertices of each panel of cloth. What you see in the simulation is Sketch Up geometry, which is created at the beginning of the sim, and modified in real-time; the main script is in the floor's scripted field, which creates a command used in the hidden physics objects.

Hello Everyone, new member here.

Can anyone point me to a working example using the 'UnTouch' script functionality? I've played around with it, but can't quite seem to get it to work. I apologize if this has long since been covered somewhere, but I can't seem to find any examples. Thanks.

Davidfi1

Did you mean OnTouch?

OnTouch

JeremyGBertin

No, I was not referring to the onTouch which is in the UI, but rather the opposite signal for when two objects stop touching.

Looking through the ruby code there seem to be events for onTouch, onTouching, and onUnTouch and I would like to know whether these are accessible for use. I am specifically looking for an example making use of an event which can fire code when two objects stop touching.

The effect I am trying to achieve it to set a variable when two objects come into contact, and clear the variable only when the objects move apart. Thanks!

Wacov

Basically, you use:

ontouch{
   #your code here
   #code
   #code
   #more code
   #etc
}

In the scripted field. The code you put between the brackets will be executed, in the case of ontouch, upon every collision with another object. ontick{...}, onuntouch{...}, and ontouching{...} work in basically the same way, with ontick executed every frame, onuntouch whenever the object stops colliding, and ontouching every frame the object is colliding with another. With any of the the touch events, you can also access the object being collided with, the exact point3d of the collision, and the impact speed of the collision, using:

ontouch{|toucher,speed,pos|
   #code
}

You can then use them as variables in your event code.
