The ball joint's min and max need to be set to 0.

yeah, you're right

I think the only max would be the size of the file. Aside from the sound playing past the end of the simulation. I might be able to fix that problem on Win but I dont know about Mac...

It might be possible. Ill look into it.

I think a setVar controlled magnet uses it to reset itself.

and about a third of components weren't used either.

Here is an example with several different variations on lookAt LookAtExamples.skp

if frame>1;push(getVar("foo"));elsif rand<=0.4;setVar("foo",15);else;setVar("foo",5);end Not totally sure if that works... if frame>1;0;elsif rand<=0.4;push(15);else;push(5);end That does what I think you're trying to do.

Interesting developpement, I like the way you manage flight parameters indicators have a look on this thread , could be useful :http://www.sketchucation.com/forums/scf/viewtopic.php?f=15&t=16632&p=131285&hilit=+dimension#p131227 MALAISE.

@unknownuser said: By the way, C.Phillips, mind explaning that script? I wouldn't mind figuring out how it works What's g? ...all I can get so far is that gas is 100, if gas is smaller than 0, then the motor stops, and when up is pressed, g is equal to gas, which is equal to one less than g, thus lowering the value by 1 each frame up is>0 (pressed). But can you just use a letter as a variable? It doesn' seem to work for me... Yes "g" is a temporary variable. It could have been "gas" or (almost) anything. I tested the code and it seems to work as expected. How does it not work for you?

The code in the onTick field is executed every rate frames. If rate is 0 then every frame.

@malaise said: Hi =Physicsguy= Color sensor's idea is very interesting. I had suggested a similar idea using a mechanical sensor (switch). The question is: how to read this sensor information and link it to drive motor, hinge.... ? MALAISE Mechanical sensors are now possible if you use an object with an onTouch field.

Destroying something isnt the hard part. The hard part is getting it back again when the simulation resets. But I'll look into it.

Magnetic Deflecting Armor

If you did a playsound in onTick or onTouch and didnt set the rate to something a lot higher that 0 it might crash. If that wasnt it maybe it was a bad wav.

I don't think SP is particularly hard to understand, but the fragmentation of the ad-hoc documentation is a stumbling block for most people.

The original idea was that the joints are atomic and can be joined to do what you want. Just connect 3 Springs and you have the same result as a specialized 3DSpring. The problem is the "just". Its a pain to connect up 3 joints. Not to mention not simple to envision what the result will be. SPIV will fix the pain to connect part. But a 3d spring may be possible in SP3x. Maybe a desiredPosition property on objects or something.

Yes. The video is for the next version. It is called SP3x (for experimental) and will probably be out in a few days. The reason for 2 versions is that models that use OnTouch and OnTick might not work in future releases. I am not planning on restricting 3dwarehouse. But I want to make it clear that these models are much more likely to break in the future. I am really happy that most 2.0 models still work in 3.0 and I want to try to keep that going.

Umm... Please post that on the Newbie forum

I am with Sepo...
