Flow Nodes

Every node the Flow editor offers, grouped exactly as the palette groups them. Each node's one-line description is the same text the editor shows in its info pane (and the palette's tooltip) when you select the node, so the two cannot disagree. Nodes with their own page link to it.

Input

Node	What it does
Slider	An interactive slider that outputs a number - the quickest way to hand-tune any numeric input live.
Color Picker	Outputs a color chosen with a swatch - the color source for anything that paints.
Switcher	A radio-button list that outputs the index of the selected item - a hand-operated multi-way switch.
Number	A constant numeric value - the simplest source node.
Vector3	An x/y/z triple - used as a direction, an offset, or most often a fixed point in the world.
Toggle	A checkbox that outputs true or false - a hand-operated on/off switch.
Random	A random number in a range - deterministic, so every peer sees the same "random" value.
Time	The synced clock as a value - the heartbeat behind almost every animation recipe.

Scene

Node	What it does
Object Selector	Binds the graph to a scene object - the sink every effect must reach, and an object reference for sensor nodes.
Velocity	Outputs how fast the connected object is moving right now, in metres per second.
Measure	Reads a number off an object: how tall it is, where its top is, how fast it is going.
Spawn	Makes copies of an object while the simulation runs - crates off a conveyor, targets, debris, ammo, waves of anything.

Object Flow

Node	What it does
Flow Input	Declares a public input socket for an object flow - the way the Scene flow feeds a value into an object's own graph.
Flow Output	Declares a public output socket for an object flow - the way an object publishes a value back to the Scene flow.
Object Flow	Embeds an object's own graph into the Scene flow as a single card - the way to compose object flows into a bigger machine without opening each one.

Game

Node	What it does
Set Game State	Switches the shared game state (menu, playing, paused, over) when a pulse arrives - every peer follows the same state.
On Game State	Fires a pulse when the shared game state becomes the one you pick - the hook for "when the round starts".
Set Active Camera	Makes a camera object the active view for every player when a pulse arrives.
Set Look	Points the player's view at a target when a pulse arrives - a cutscene glance or a spawn orientation.
Game Start	Fires once when the game starts (Play, or a round reset) - the place to spawn, reset counters and arm timers.
Travel to scene	Loads another saved scene by name when a pulse arrives - a door to the next level, replicated to everyone.
All Players	Iterates the connected players so a per-player value can be read, or a HUD row shown, for each of them.
Set Variable	Stores a named value in the replicated scene variables when a pulse arrives - shared state without an object.
Get Variable	Reads a named scene variable as a value - the read side of Set Variable, live on every peer.
Game Time	Seconds since the game (or the round) started, the same on every peer - a clock that pauses with the game.
Player Variable	A value kept PER PLAYER (score, lives, team) - each peer reads its own row, or a named player's.

Character

Node	What it does
Character Controller	Turns the connected object into a walking, jumping character driven by the player's movement input.
Move Input	The player's movement input as numbers - stick or WASD axes and the jump button - for driving things by hand.
Possess Object	Puts the player in control of the connected object when a pulse arrives - a vehicle, a turret, a ball.
Camera Follow	Makes the camera follow the connected object at a set distance and height - a third-person or chase view.
Move Speed	Overrides the character's walking speed while a value is wired - sprint, mud, slow motion.

HUD

Node	What it does
HUD Screen	Shows or hides a whole HUD screen (a named layer of elements) while its condition holds.
HUD Bar	Drives a HUD bar element's fill from a number - health, fuel, progress.
HUD Button	Fires a pulse when a HUD button is pressed - the on-screen counterpart of On Click.
HUD List	Fills a HUD list element with the items a value provides - an inventory, objectives, players.
HUD Rows	Appends or replaces rows in a HUD rows element from a pulse - a log, a chat, a scoreboard feed.
HUD Input	Reads what the player typed into a HUD input element as a value.
HUD Set Input	Writes a value into a HUD input element when a pulse arrives - to prefill, clear or correct it.

Logic

Node	What it does
Math	Combines two numbers with an arithmetic operation.
Compare	Compares two numbers and outputs true or false.
Gate	Boolean logic on two inputs - AND, OR, NOT, XOR.
Map Range	Remaps a number from one range to another - the glue between free-range sources and bounded parameters.
Select	Chooses between two values: outputs a when the index is low, b when it's high.
Latch	Holds a boolean until told otherwise - set, reset and toggle pulses make it a memory bit.
Delay	Passes a pulse on after a set number of seconds - the timing of a fuse, or a door that closes later.
Sequence	Fires its outputs one after another, one per pulse, then wraps around - a step-by-step trigger.
Once	Lets exactly one pulse through until it is re-armed - a checkpoint, a pickup, a first-time event.
Counter	Counts trigger pulses and outputs the running total.
Loop	Sweeps a number from one value to another over time, repeating - a ready-made animation ramp.
Timer	A delay line: outputs its input as it was a set number of seconds ago.
Distance	Measures the live distance between two things in the scene.
Proximity	True while two things are within a radius of each other - a distance sensor with the threshold built in.
Look At	Keeps the connected object facing a target - another object or a fixed point - every frame.
Set Color	Paints the connected object's material with a color, re-applied every frame.
Visibility	Shows or hides the connected object based on a boolean.
Set Shader Uniform	Writes one number inside an object's shader graph, so a trigger, a

Triggers

Node	What it does
On Click	Fires a short pulse when its object is clicked - the bridge from user input into the graph.
Key Press	Fires a pulse while a keyboard key is pressed - the bridge from your keyboard into the graph.
On Impact	Fires a pulse when a physics simulation lands the connected object on the ground or another object.
On Enter	Fires a pulse when something enters a trigger volume - the checkpoint, doorway and pressure-plate node.
On Exit	Fires a pulse when something leaves a trigger volume - the other half of On Enter.
On Rest	Fires a pulse when a physics body has finished moving - the counterpart to On Impact, which fires when it starts.
On Hit	Fires a pulse when a hand or a player knocks the connected object, with how hard and whether it was you.
Gamepad Button	Fires a pulse (or holds a level) while a gamepad button is pressed - the pad's counterpart of Key Press.
Gamepad Axis	A gamepad stick or trigger axis as a number between -1 and 1, with a dead zone.

Animation

Node	What it does
Shake	Jitters the connected object around its resting position - rumble, nervousness, impact feedback.
Spin	Rotates the connected object continuously around one axis.
Bounce	Bounces the connected object up and down off its resting height, like a dribbled ball.
Orbit	Circles the connected object around its resting position on the horizontal plane.
Path patrol	Walks the connected object along a series of waypoints you click into the scene, facing along the path.
Animation Finished	Fires a pulse when the connected object's animation clip reaches its end.
Animation Marker	Fires a pulse when the connected object's animation passes a named marker.
Animation State	Reads the connected object's animation transport as a number - playing, position or progress.
Play Animation	Starts, stops or restarts an animation clip on the connected object when a pulse arrives.

Physics

Node	What it does
Mass	Gives the connected object weight for the physics simulation - objects with a Mass fall and collide.
Bounciness	Sets how much the connected object rebounds in the physics simulation (restitution).
Friction	Sets how much the connected object grips surfaces in the physics simulation.
Angular Velocity	Gives the connected object a constant spin under physics - a rolling barrel, a spinning hazard, a rotating platform other objects can stand on.
Collider	Overrides the collision shape the physics simulation uses for the connected object - the flow equivalent of the Inspector's Physics > Collider pick, and it wins over it.
Motor	Drives every hinge joint attached to the connected object - the flow way to make wheels turn, turntables spin and doors swing under power.
Impulse	Pushes or spins a physics body when an event fires - a jump, a kick, a cannon, a nudge.
Set Velocity	Sets a physics body's speed outright - to launch it at an exact velocity, to hold it at a constant one, or to stop it dead.
Joint	Attaches two objects to each other when an event fires - a hinge, or a rigid weld.

Effects

Node	What it does
Pulse	Throbs the connected object's scale in and out around its resting size.
Blink	Flashes the connected object on and off at a steady rate.
Sound	Plays an Explorer audio clip on the connected object when a pulse arrives - spatial, replicated, by content hash.
Particles	Emits a particle effect from the connected object - a preset burst, a stream, a trail.

Music

Node	What it does
Device Param	Writes a number into one parameter of the connected audio device every frame - an LFO on a cutoff, a fader on a level.
Device Level	The live output level of the connected audio device (or a wired one) as a number - a meter you can drive anything with.
Transport	The shared music transport as a number - beat, bar, phase, bpm or playing - identical on every peer.
Note Trigger	Plays a note on the connected audio device when a pulse arrives - a drum pad, a sampler pad, a synth key.
