Undo/redo systems are essential for complex interactions, but implementing reliable, mergeable undo stacks across diverse actions is error-prone and time-consuming.
Install and wire up the UndoRedoService, implement a custom IUndoableCommand, and attach it to your action triggers via ExecuteAsync to enable undo/redo.

Implement an undo redo system in Unity by wiring up an UndoRedoService that manages deterministic stack-based history. Create custom IUndoableCommand instances and attach them to action triggers via ExecuteAsync to enable reversible operations.
Mergeable commands use IMergeableCommand to condense consecutive actions into a single history entry. This optimizes the undo stack by preventing repetitive operations, like continuous slider adjustments, from flooding the fixed max size history.
Yes, the command pattern exposes reactive state such as CanUndo and CanRedo alongside event-driven notifications. These include CommandExecutedEvent and UndoPerformedEvent to properly update UI workflows and analytics.
Add reversible actions across modules by utilizing built-in commands like CompositeCommand and MoveTransformCommand. These pluggable components manage cross-module operations within a unified, stack-based command history.
Track undo and redo events by subscribing to built-in event types like UndoPerformedEvent, RedoPerformedEvent, and UndoStackClearedEvent. These event-driven notifications expose action history for game tools UI and analytics integration.
Configure a fixed max size for the undo stack using the ready-to-use service installer. This manages the deterministic history limits, automatically discarding the oldest commands when the stack capacity is exceeded.
