MovingDay

MovingDay

MovingDay is an advanced structure relocation mod for Valheim that allows players to select, rotate, and move anything from individual build pieces to entire buildings and structures in real-time, complete with safety checks, container metal cargo handling, tamed animal transport, and automated terrain replication.

Features

• Structure Selection & Smart Anchor: Select individual pieces (G) or target an entire building using connected BFS flood-fill selection (H). The first piece selected (or the piece aimed at when entering Move Mode) acts as your anchor point for placement. World-generated structures and dungeons are automatically protected and cannot be targeted.
• Move Mode (L): Relocate the selected building in real-time using a blueprint ghost preview with exact orientation preservation—no more 180-degree flips when facing containers or furniture.
• Height Adjustment: Smoothly raise or lower the structure placement height in Move Mode using configurable hotkeys (defaults: UpArrow / DownArrow), scroll wheel steps (Alt + Scroll), or snap it flush back to the aimed surface (Home).
• Grid-Snapped Rotations: Relocations are locked to standard Valheim 22.5 degree world-space increments, ensuring placed structures align perfectly with standard Hammer build snaps and center correctly.
• Terrain Cloning & Reversion (Held LeftControl): Replicates and rotates excavations and terrain leveling to the destination, and restores the source terrain to its natural state.
• Dynamic Surface & Multi-Story Tracking: The placement ghost tracks the exact surface your crosshair points at (terrain, rock, floor pieces, or stone foundations). Upper-floor objects and multi-story buildings maintain proper elevation without floating.
• Anchor Piece Bottom Alignment: Automatically calculates the physical bottom bounds of the anchor piece so that center-origin pieces (like 2m walls, 1m walls, or poles) sit flush on the targeted surface rather than sinking half-way into the floor, while preserving the relative depth of underground cellars and basements.
• Safety & Metal Cargo Handling:
• Blocks placement if other players are in the footprint (or teleports them along with the building).
• Blocks movement or drops metal cargo into cargo crates depending on configurations.
• Tamed Animal Transport: Scans and teleports tamed animals in a 6.0m radius of the structure safely to the destination.
• ZDO Network Authority: Claims authority for ZDOs during relocation to ensure network synchronization without duplication or data loss.

How to Use

1. Equip your Build Tool (Hammer).
2. Select Pieces: Hover over pieces and press G (to select/deselect individual pieces) or H (to select the entire connected structure). The first piece selected (or the piece you aim at when entering Move Mode) acts as your anchor point. Selected pieces will pulsate with a green highlight. (Hold Shift or Control while pressing G or H to instantly clear the entire selection).
3. Enter Move Mode: While standing near the selected structure, press L to enter Move Mode. A blue-green ghost preview of the structure will spawn.
4. Relocate:

• Walk or Teleport to your destination. The preview ghost will follow you (even through portals!).
• Rotate the structure with the mouse scroll wheel.
• Adjust Height using Up/Down Arrows or Alt + Scroll Wheel (holding Left Shift enables fine-tuning). Press Home to instantly snap the height flush back to the targeted surface.
• Hold Left Control to copy the modified terrain at the source and automatically replicate it at the destination.

1. Place: Left-click to place the structure at the destination. Right-click or press Escape to cancel.

> [!IMPORTANT] > You must enter Move Mode (Step 3) prior to teleporting or moving away from the structure. If you teleport before entering Move Mode, the source area will unload from memory, and the mod will not be able to cache the structure's layout or generate its preview ghost.

Server & Multiplayer Architecture

> [!NOTE] > MovingDay does NOT require a server-side installation! > Client-Side by Default: All structure moving, selection, terrain restoration, ghost previews, and local diagnostic scans work 100% client-side in singleplayer and when connecting to unmodded dedicated/hosted servers. > When is Server Installation Needed? Installing MovingDay on a dedicated server is strictly optional. It is only needed if server admins wish to perform world-wide scans and cleanups (mdscan and mdclean all) across distant, unloaded sectors. > * Vanilla Friendly: Unmodded players can join a server running MovingDay with zero mod requirements or desyncs.

Admin Diagnostic & Cleanup Tools

MovingDay includes native diagnostic tools to scan for and clean orphaned, buried, or corrupted database objects (ZDOs) that cause lag or clutter over time.

Commands

All commands can be typed directly into the F5 Console (e.g. mdscan) or the Chat Window (e.g. /mdscan):

• mdscan [here/origin] [radius]: Scans for orphaned ZDOs without modifying anything.
• mdscan — Scans across all loaded sectors (or full world if connected to a modded dedicated server).
• mdscan here 50 — Scans within 50 meters of your character.
• mdscan origin 100 — Scans within 100 meters of the world spawn altar (0, 0).
• mdclean: Displays command usage and performs a safe dry-run scan.
• mdclean <ZDOID>: Permanently destroys a single specific orphaned ZDO (e.g. mdclean 10521:3).
• mdclean here [radius]: Cleans orphaned ZDOs near your character (default: 20m).
