State Exit (Flowgraph State Node)

Overview

• Node Name: State Exit
• Type: State node (created via _flowgraph_createStateNode)
• File: extensions/flowgraph/nodes/states/stateExit.lua

Exit point for a stategraph. When reached, triggers a named transition to leave the current state.

Pin Schema

Input Pins

Additional pins: Supports manually added state type pins via allowedManualPinTypes.

Node Properties

Internals

Behavior

• drawMiddle() - Displays the transition name in the node UI.
• drawCustomProperties() - Provides a combo box to select from available transition names defined on the parent state node.
• Serialization - transitionName is saved/restored with the graph.

How It Works

1. A stategraph can have multiple State Exit nodes, each with a different transitionName.
2. When execution reaches this node, the named transition fires on the parent state machine.
3. The transition name is selected from the parent node's getTransitionNames() list via the editor UI.
4. The parent stategraph node uses the transition name to determine which state to enter next.

Key Dependencies

• _flowgraph_createStateNode(C) - state node factory
• Parent state node's getTransitionNames() - provides available transition options

Additional Methods

C:_onDeserialized(data)

Called after the node is deserialized (loaded from file). Restores runtime state from saved data.

Parameters:

• data

C:_onSerialize(res)

Called when the node is serialized (saved to file). Returns data to persist.

Parameters:

• res

C:init(mgr)

Initializes the node, setting up pins and default properties.

Parameters:

• mgr
