I tried to create a slider-controlled emitter. In the "strenght" box I put this formula:

slider('power')*100

But the aspected "power" bar wasn't showed. The emitter started to replicate himself normally.
Someone can help, please?

I asked a similar question and itseems to be incompatible with SketchyReplay.

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

Then I downloaded the video with enough resolution to read the code and tried to use it (after some modifications). Obviously it didn't work.
That is all I know about this point.

I found a new way to make a truster in SP:

1. truster option (in UI)
2. a magnet linked with a magnetic object
   and the new solution:
3. a gear link between a motor and a slider. Motor is linked to a static object, slider is free.
   The model shows the three options together.

A bug (I don't know where it must be post, so I ad here): when I click on the piston joint, Internet Explorer says "script error"

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?
