OpenRCT2 Undo

Undo/redo plugin for OpenRCT2. Tracks player-initiated actions and lets you reverse them with Ctrl+Z / Ctrl+Y.

Supported Actions

• Small scenery, large scenery, walls, banners (place/remove)
• Footpaths and footpath additions (place/remove)
• Track pieces (place/remove)
• Park entrances, ride entrances/exits (place/remove)
• Terrain raise/lower/smooth/set height (via tile data snapshots)
• Water raise/lower/set height
• Surface style changes

Only the local player's actions are tracked. Ghost/preview actions are ignored. History is capped at 50 entries. New actions clear the redo stack.

Action Batching

Rapid sequences of actions are automatically grouped into a single undo/redo entry. This means dragging terrain up and down, placing a row of path tiles, or other quick repeated actions can be undone in one step instead of individually.

Batching uses a debounce window (default 5 ticks, ~165ms). Actions that occur within this window of each other are merged into a single batch.

Shortcuts

• Ctrl+Z - Undo
• Ctrl+Y - Redo

Rebindable in OpenRCT2's keyboard settings.
