Definition

Namespace: Paragon.Core.ActionSystem.Editor Assembly: Paragon.Editor.dll

public class ActionVariableReferenceMenu

Description

ActionVariableReferenceMenu provides a popup interface for selecting which parent variable an ActionVariable should reference. It traverses the action hierarchy to find compatible variables based on type matching.

This class is used internally by ActionVariableDrawer and appears when clicking the reference button on an ActionVariable field.

Behavior

When displayed, the menu:

1. Traverses parent actions in the inspector hierarchy

2. Collects all ActionVariables containers from parent actions

3. Filters variables by type compatibility with the current variable

4. Displays selectable options including "None" to clear references

Variable names are automatically formatted with ObjectNames.NicifyVariableName for display.

Type Matching

A variable is included in the selection if its type is assignable to the current variable's type. This allows selecting base types when the variable expects a derived type.
