Change the setVar('1',1) to setVar('timer',0).

It should work.

Its possible. But each field I make script controllable it dramatically adds to the complexity of the SP3 code. And it slows the simulation. Both of these issues will be fixed in SPIV.

I think the best fix going forward is to set the joint parameters in an onTick (or whatever) event. So rather than having a formula in the accel field instead in onTick (or whatever) you can do something like this:

> joint.accel=righty*100.0
> joint.min=joint.min+10.0

Great that'll solve some of my problems.

From looking at the scrip it would possible, but I don't know enough of script to do it .

Is there a tutorial section for sketchy physics like sketch up tutorials?

Please let me know.
Well Here's a SPwiki that can teach valuable information...http://sketchyphysics.wikia.com/wiki/SketchyPhysicsWiki

I forget exactly when but it is needed in some cases. For example if you have a body that is magnetic but there are no magnets near by it will stop moving and "freeze". If a magnet passes by it will not move because it is frozen until something actually touches it.
OK thanks I just couldn't figure out.

@cphillips said:

Not the way you describe it.
As I said before a single joint that is (in your example) a hinge and a spring and a servo would be a UI mess. And I would have to code for every possible permutation. What if you wanted a piston,spring,servo,hinge,motor. Ug!

Instead you will be able to take a slider and a spring and a servo and a hinge with all the settings you want and the group them into a object that is reusable. Copy and paste or even post to 3dwarehouse.

But in the specific case of a car rigging there will be a shortcut in SPIV. Something called a ray cast car is available in the new version of the physics engine. Basically you say this body is a "car" and these bodies are "wheels" and it handles connecting them with all sort of real world values like torque, breaking, steering, differential and suspension setup.

Like in stunt playground 2.0! That would be great! I made a car in stunt playground using the junk car body and the monster truck suspension and wheels, it had 7 gears and went 200mph.

What's it for?

I wouldn't think it would be to hard in spiv.

Not an OLD pc. 3.07 ghz cpu. 2 gigs ram, 512 mb nvidea video card. Windows XP

I'm wondering if I need the paid for version of SU, with ruby and all that? SU stays running, it's that if I put in something wrong (blueish text area?), the UI doesn't fully open properly again.

I've had that problem to. if you save the file and go back into it is the script still there. Did you click on the group you put the script in again. Also i have free I don't see why you would need pro.

there that works

if frame>=350;[1,5,3,9,2,3,1,0][(frame/50)%8];end

Hmm actually it doesn't work not sure why though it should.

Hello, thanks for this great physics extension!
I have a question about keyboard shortcuts - is it possible to define shortcuts for SketchyPhysics tools?
It is not possible to set it via Window->Preferences->Shortcuts since I cannot see any SketchyPhisics tools there. Is there any other way... ?

I don't think that's possible.

I could do that if cpillips wants me to that way he wouldn't have to. It would be sp3 though.

if frame==349;[1,5,3,9,2,3,1,0][(frame/50)%8];end

That should do it. frame==350 does not work for some reason.

@thrundar said:

It must be that springs do not operate with an arc movement, only straight line of travel.

Yes that's true

Thanks physicsguy I didn't now what to say.

All the boxes have to be a separate group.

PPM-2 (2).skp

You have the spring grouped two times. You can't group a joint more than once.

Could you post the model. You can try scaling everything up.

This is going sound weird, but How do I post a model. Post it here? On google 3d warehouse?

Just post it here.
