command-pattern-undo

Undo and redo functionality is implemented using the Command Pattern with a history stack. This Skill provides an ICommand interface and CommandHistory class to manage reversible operations like placing or deleting objects in a Unity Editor tool.

The command pattern encapsulates operations into objects, enabling parameterization, queuing, and logging. Use it for gameplay systems like strategy game moves or crafting systems when discrete operations must be reversible and tracked.

Yes, this command pattern undo implementation supports strategy game moves. It manages a full undo and redo history stack, allowing discrete gameplay operations to be reverted or reapplied seamlessly.

To create a reversible PlaceBuildingCommand, instantiate the command with a grid, cell coordinates, and building type. The provided ICommand interface allows the operation to be executed, undone, or redone via the CommandHistory class.

Yes, this undo redo history stack works without additional dependencies. It operates independently using the provided scripts and references to manage command execution and history tracking.

A command history stack handles discrete reversible operations but may consume significant memory if unbounded. It is best suited for editor tools and gameplay systems requiring distinct action tracking rather than continuous state transitions.
