Glossary

Terms used in this manual and in the app, scoped to what’s in the 0.2.0 demo.

Term	Meaning
Action	A behavior node that plays a sprite animation for a duration. In this demo: Idle and Walk.
Asset	See Sprite. A named animation belonging to a pet or object.
Behavior graph	The visual node program that defines what a pet does. Runs from Start, through your nodes, and loops at End.
Bundle	A shareable file holding one custom pet (.spe) or object (.speo). Export from the editor; add with the Library’s Import.
Card	A pet or object tile in the Library grid.
Custom	Pets/objects you create or clone. The opposite of Default. Editable and deletable.
Debug (preview)	Running your graph inside the editor to watch it animate, with the active node highlighted. Not a separate window.
Default	The read-only pets and objects that ship with the app. Cannot be edited or cloned.
Drag	Picking a pet or object up with the mouse to move it. Always on in this demo (except in Focus Mode); becomes a node behavior in Early Access.
Duration	How long an action runs: a random value between a Min and Max, set in seconds (Time mode) or whole loops (Loops mode).
Fall	A dropped pet descending under gravity until it lands. Always-on in this demo (not a node); becomes a node behavior in Early Access.
Focus Mode	Makes pets/objects click-through so clicks pass behind them. On macOS they fade on hover; on Windows they hide. Disables dragging.
FPS	Frames per second: how fast a sprite animation plays. Default 4; adjustable per sprite and per node.
Frame	One still image in an animation.
Hide All Pets	A tray toggle that hides every live pet/object at once without turning them off.
Layer (Back/Front)	Whether a live item draws in front of or behind other live items of the same type.
Library	The main window: browse, toggle, and manage pets and objects.
Live	An item currently spawned on your desktop. Shown by a green badge on its card.
Node	A single unit in a behavior graph. This demo has five: Start, End, Idle, Walk, Random.
Object (prop)	Static/animated scenery (bed, plant, campfire). Has animation states and layers, but no behavior graph.
Port	A connection point on a node, either In (left) or Out (right), that you wire together.
Random	A logic node that picks one of its connected outputs (weighted) to continue down.
Scale	A multiplier for an item’s on-screen size, from 0.1× to 20×.
Slicer	The tool that cuts a sprite-sheet image into individual frames.
Snap to grid	An editor option that aligns nodes to the background grid as you drag.
Sprite	A named animation (a sequence of frames) that a pet or object can play.
Sprite sheet	One image holding many frames in a grid; sliced into frames by the Slicer.
State (object)	A named animation for an object (e.g. “on” / “off”), built from layers.
Start / End	The lifecycle nodes: Start is where a graph begins; reaching End loops back to Start.
Tray	The menu-bar (macOS) or notification-area (Windows) icon where the app lives and is controlled.
