Variable

Internal storage backends for the Action Variables subsystem. The Variable abstract base class defines a uniform get/set API, with two sealed implementations that determine where the value lives.

Architecture

Comparison

Aspect	FieldVariable	DynamicVariable
Storage	Reads/writes the actual field on the owner object via reflection	Holds value in an internal object field
Created when	An Action field is marked with [Variable]	ActionVariables.AddVariable() is called at runtime
Owner	Requires an owner object (the Action instance)	Standalone — no owner
Removable	No — discovered automatically from reflection	Yes — via ActionVariables.RemoveVariable()
Visibility	internal sealed	internal sealed

Classes

Class	Description
Variable	Abstract base defining Type, Name, GetValue(), and SetValue().
FieldVariable	Reflection-backed variable that reads/writes a field on an owner object.
DynamicVariable	Self-contained variable storing its value internally.
