English shows an example of a layer following a moving curve, and rotating to follow the curve as it moves.

How was that achieved? It's currently complicated to set up, so I'll describe here how it works. Hopefully a better design can be used to make it a lot more intuitive in Studio.

The animation lasts for 32 seconds and has 3 layers:

  • moving blob - an encapsulation of 3 layers. its origin is connected to the exported valuenode "moving point"
    • direction of movement - the fuzzy white beam of light
    • inner circle - the smaller yellow circle. not animated at all.
    • outer circle - the larger red circle. not animated at all.
  • line - the moving curve which the object follows. has waypoints at 0s, 16s, and 32s to make the line move. uses 4 exported animated valuenodes:
    • vertex1 - the position of the beginning of the curve
    • vertex2 - the position of the end of the curve
    • tangent1 - the tangent at the beginning of the curve
    • tangent2 - the tangent at the end of the curve
  • black background - a solid black background. not animated at all.
