[Plugin]SketchyPhysics3 alpha.

i was thinking for something like a car(magnet) rolling down a hill, where there are leaves(magnetic) so the leaves don't move(frozen) till the car comes into range. this could be sort of a fake wind simulation etc...

If you make the leaves out of boxes friction will hold them on the ground until the car is near.

hello

i've awaited sp3 and now its there (kinda). yippie^^
i hope the bugs are quickly removed, for example the magnets arent working in my sp and it causes errors...

I cant fix the bugs unless you report them. How do magnets fail? How can I reproduce the problem? Can you post a model?

klaufi

that shouldnt be necessary...
when i make an object to a magnet and write some number into the strength field and then push on run nothing happens... it runs like normal, just the block is static and no force slider is there as it should be...and i cant get out of the run mode by reset, just by clicking on select or some other tool, but then the run button doesnt work anymore at all...and when i close su the pc shows me a message, that su doesnt work properly

after reopening su everything is normal again
oh, yeah, im using su 6

btw. i have found a solution for my robot joints:
i have made two motors in opposite direction, one set with slider and one with the key code (rightx for example), both with the same settings, so the one motor pushes exactly against the other until the one your controlling is stronger or weaker

heres an example (model downloaded from warehouse)

edit:
there are functions on both the arrow keys and wasd

and ive found another error: while running sp and puching some of the wasd buttons he sometimes leeves the run mode and selects the tools (A)rc or (S)cale

some experiment on a robot

Ok, I know what causes that. Its when you enter a bad formula. Ill fix it in next release.

You can do motors like you describe by setting the controller to:
0.5-slider('motor')

Make sure the Control Panel window has focus when using the keyboard.

ah, ok, thanks^^

cool
are there other commands you can write there?

Yes. Lots.

Try this with a servo to make it oscillate.
Math.sin(frame/10.0)/3.0

Or this to make it move once per second:
Time.now.sec*(1/60.0)

klaufi

what are these commands and where can i find out more about them excited
or are you writing something about them soon?

sketchyman

It doesnt work to me please help!! this shows me at the start
Thanks a lot
Sketchyman

This is shown when i turn sketchup on

sketchyman

When are you planning to release the official version??

sketchyman

I installed skp6 and it works !!! great!!

sketchyman

Can you please post some instructions because the magnet somehow doesnt work to me!!! it just freezes and i have to turn it off. PLease help

I am changing it a little bit but when I am done I will write something up.

Basically Controller can be a little fragment of Ruby. So you can type in any legal ruby syntax that results in a number:

2+2
3*(15/2.0)
3.14*Math.sin(1.0)

You can even put stuff like

if frame<30 then 0.0 else 1.0 end

That will cause a joint to move to 1.0 after 30 frames.

Sketchyman:

-Sorry about the error on SU7. I have seen one other person have this problem but I dont know what causes it or how to fix it yet. If you manage to figure it out please let me know!

-Final version will be released when it is done. No specific date.

-See the magnets thread for instructions on the magnet. If you are still having problems post a description of the problem (and a model if possible) in that thread.

Is their anyway you could add a concave hull.

I tried to download thruster magnet model but its made with version 7.0 and i cant install sketchyphysics on that one. please post some models made with sketchup 6. thanks a lot

I saw a video of SketchyPhysics 3 showing a piston linked to a normal cylinder. When activate the corrispondent slider, the cylinder seems to multiply.Is that possible in the current version?

That feature isn't in yet. I have to figure out how to make it work with replay.

Sketchyman, could you try this to fix your SU7 error. Find the file win32api.so in your ...Sketchup 7\plugins\SketchyPhysics3 folder and copy it to just ...\plugins\ and see if that fixes the problem.

Nope, sorry.

Sorry if this has been asked before (noob here) but I noticed v2 was mentioned as having Mac support at some undefined time in the future. Will this be implemented in v3?

Cheers
