I have a curve and a sphere, and I would like to make 5 copies of that sphere move along the curve.

It's possible to duplicate them along the curve by making the sphere a child of the curve and switching on dupliframes, however don't know how to move the duplicated spheres along the path - perhaps there's an offset option I'm missing?

Using the a Follow Path constraint I can offset the sphere along the path, but I can't duplicate it.

I've also tried the Array and Curve modifiers together - again this doesn't let me move the duplicated spheres along the path.

Any suggestions?

Five spheres moving along a path

I tried to obtain what you describe: it wasn't extremely simple, but I think the result should be something near, at least:

How it is done?

  • added the path
  • added a 5 vertex segment
  • added a curve modifier to the segment (highlighted in the above image), targeting the curve, along X
  • now moving the segment along X (animating with loc keyframes) it follows the curve
  • then added 5 spheres, each snapped to each of the segment vertices, then each vertex parented to the segment
  • alternatively, and more efficiently, you can parent one sphere to the segment, then select the segment and enable duplication on "verts".

the following images show the alternative method, and also a movement along a more complicated curve:

there are probably other ways, but this should be near.
