Flow Output
Declares a public output socket for an object flow — the way an object publishes a value back to the Scene flow.
Input: any value type (the socket is gray = accepts anything)
Only meaningful inside an object flow.
Parameters
| Parameter | Default | Meaning |
|---|---|---|
| name | out | the socket label shown on the embedded Object Flow node |
| fallback | 0 | published while nothing is wired in |
Values, not effects
Animation and effect nodes (Spin, Pulse, Sound… — the orange sockets) cannot wire into a Flow Output: they do something, they don't carry a value. Publish the value that drives them instead — the Time, Math, Slider or Loop node feeding the effect.
One frame of latency
Outputs are collected at the end of a tick and delivered to the Scene on the next one. That single frame is invisible in practice and is what makes flows safe to compose without infinite loops.
Practical example
A pressure plate that reports its state:
- In the plate's flow, wire an On Enter → Counter chain into a Flow Output named presses.
- Embed the plate in the Scene flow (right-click ▸ Add flow to Scene graph).
- In the Scene, wire the card's presses socket into a Compare node (
>= 3) and on into a door's Object Flow input — three presses, the door opens.
