I just fixed 1 and it will be in next release. 2 is harder. It uses inches because Sketchups underlying unit is inches. The SU UI has all kinds of automatic conversion of inches to whatever units are set. The SP UI doesnt have that and it would be tricky to write something that correctly handles every case. Like 1 3/4'

You know the key detection system I use? That'd work for this.

OK. Nice, love the idea of a help window!

THANKS FOR ALL YOUR HELP!

If you want your vibrating object to be movable, attach a hidden, noCollision counterweight using a rapidly oscillating slider/piston joint (You can use BTM's code). The counterweight can be inside the object.

... Something else that may be included...

[image: FfHN_Picture1.png] ...I think I might improve the running speed, but it messes up the leg/ arm movement a bit too much I've also been thinking about adding "kick" to the list, but the codes seem complex enough as it is

Hoping for the Rube Goldberg Machine, it could be nice to render.. i think to weeks for the competition should be a minimum

@cphillips said: 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.

@cphillips said: 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.

It looks like its a bit complicated so it wont be anytime soon. sorry.

Ok. I will update the old SP and SP2 google pages to point to the new Wiki and that should fix the Google links. And effectively become the new home for SP. Thanks to everyone that has made the Wiki such a success!! Chris

I don't think it would crash. It would probably get slow if you have too many tho.

That's coming in SPIV

Im not really trying to do anything in particular. I just thought it might be useful for restricting the position/rotation of an object.

Now working. Although at a newbie level, I have gotten a couple examples to work now. Thank you everyone for the help!

remus Between your copy here and others I've downloaded, I've been able to get magnets to work now to a newbie degree. Thank you.

Thanks everyone, i used your help on this model http://sketchup.google.com/3dwarehouse/details?mid=3459b385de291d695e28caa3b26a73fd

@unknownuser said: by CPhillips on Fri May 01, 2009 9:28 pm If you want a rotating spring use a servo and set the accel high and damp low depending on how strong and how stiff you want the spring to be. I'm also having difficulties with changing the joint settings. I'd love to be able to adjust the spring. However I need a step by step walk through on how to do that. There is much with SU I don't know and have exhausted the newby tutorials I can find that are written and explained well. Can you connect a joint to a joint without an object or part as the parent? I'm using SU7 with SUPRC31. I noticed in RC31 that I could switch to version 2...not sure if that would help or hurt things. Thanks to everyone who is lending ideas here!

@cphillips said: You can to that in SP3 with a bit of work. In onTick somwhere: setVar("centerx",0.5+(key("h")?0.5;0.0)+(key("f")?-0.5;0.0)) > setVar("centery",0.5+(key("g")?0.5;0.0)+(key("t")?-0.5;0.0)) Then you can use this: (0.5-getVar("centerx"))*5000 WOW, that is GOOD, THANKS A LOT!
