  blocks in 1.1: unable to affect anything (Message 1 to 3 of 3)

There is this code:

#declare Trans3 =
  transform {
    translate -<4*0.55, 0.55, 0>
    translate 2.9*z
  }


changing the second translate to 2000.9*z has no effect on the animation.  I
was trying to see if I could have the crosswise block start up higher, but
couldn't make any effect on the animation.

I'm also guessing that cloth will work with pre-declared objects, but not
the mechsim collissions.  Is this correct?

It has.  You of course need to change it before initializing the 
simulation data (which is done in the first run).

I have no idea what you mean.

Okay I see.   As a Useful Idiot, might I be able to make a  contribution by
submitting idiot-proofed revisions of some of  the example scenes (rather
than just griping about them?).  For example, I'm told to


// First render as still with:
//
// -w320 -h240

but knowing the image size has nothing to do with anything, I actually
ignored all those comments.

Do the objects that interact in mechsim have to be isos?   I guess not so
for clothsim, but for mechsim, do I have to?  For example, I have a blob
character pre-defined in 3.6 syntax.  May I drop a block of jello on his
head, have him punch a wall of jello, OR would I have to rewrite him as an
iso_csg?
