Float Along Flow

Carries the connected object along a Flow path — a leaf, a toy boat — at the path's speed, bobbing and turning with the current, looping at the end. Uses the nearest Flow path unless one is wired.

Output: effect (wire into an Object Selector)

Inputs

Handle Type Meaning
path object the Flow path to ride — wire an Object Selector picking it
speed, bob number override the card sliders when wired

With path unwired it rides the Flow path nearest to where the object was placed, if one is within about 4 m; with none in reach the object stays where it is.

Parameters

Parameter Default Options
speed 1 0 to 5 — a multiplier on the path's own Speed; 0 holds it in place on the path
bob 0.03 0 to 0.3 m — how far it rises and falls on the water
align on turn the object to face along the current; off keeps its placed facing

How it moves

  • Where you place it sets its lane. The object keeps its height above the path's line and its own turn relative to the current; moving it in the editor re-anchors it there. The placed pose is what the scene saves.
  • It always loops. At the end of the path it starts again at the beginning, whether or not the path itself loops.
  • The same everywhere. Its spot on the path is worked out from the shared clock, so every player — and anyone who joins later — sees it at the same place with nothing sent. Floaters placed at different spots bob out of step with each other.
  • It follows the path's line only, so it needs no particle water to move.

Practical example

A toy boat on a river:

  1. Add ▸ Water ▸ Flow path, and place a small object (the boat) on it.
  2. Add an Object Selector picking the Flow path and a Float Along Flow; wire Object Selector → Float Along Flow's path.
  3. Add a second Object Selector picking the boat; wire Float Along Flow → it. The boat sails down the river and comes back round at the end.
  4. Raise speed to 2 for a faster current, or bob for choppier water.

An Object Selector picking a Flow path feeds Float Along Flow's path input; Float Along Flow drives the boat's Object Selector

Tip

The nearest-path rule means a leaf dropped on a river needs no path wire at all — wire one when two paths run close together and you want to choose. For a path drawn as a spline, or ping-pong and run-once travel, see Follow Path.
