Hi Platypus5, you are right and sorry for not removing my post, in the meantime i have askes sort of like the same question somewhere else on the forum and got some worthwile responses. Thanks, Fred.

So, my guess is that it will be released early January.

Now, If I remember correctly, all you have to do is move the Sketchyphysics folder, sketchysolids.rb and the sketchyphysics.rb files. Worked for me.

Because concave solids are a LOT harder and slower to do physics on. @platypus5 said: I was wondering. Why is it that the collision system in Skecthyphysics works the way it does. Why is it that it can't use the wireframe of the mesh to create a concave collisian border for the object?

I'll post something on this forum as soon as its ready for testing.

Yes. A piston or a servo can be made to oscillate. If I remember correctly you set the controller to be: oscillator,100 To cause it to go from 0 to 1 over 100 frames. See an example like the laser beam mentioned in a thread on this forum.

you do realise the posting date on this? he fixed this ages ago, 2 years to be precise. how many pages did you have to crawl through to find a problem you knew how to solve?

Ha, Very cool! Thanks BTM.

What i do to avoid the "ignore" control: use a powered hinge instead of the reversed motor, then play around with the accel of the hinge until the wheels don't move at 0.5.

You can PM Chris Fullmer for an invitation.

Thats right gai, you need to be added to a special user list to be able to add/edit stuff. I thnk im signed up to it, although i stil havent gotten around to adding anything yet
