Flip It

Free placement rotation for Valheim building. Tilt, roll, and mount pieces on walls, ceilings, slopes, dirt, and roofs.

Controls

• Scroll wheel — rotate on Y (vanilla)
• Shift + scroll — pitch (X axis)
• Ctrl + scroll — roll (Z axis)

Features

• Full 3-axis ghost rotation while placing hammer pieces
• Optional surface alignment for walls, ceilings, and slopes
• Relaxed placement rules for surfaces vanilla would normally reject

Config

BepInEx/config/hardwire99.flipit.cfg

• RotationStepDegrees — degrees per scroll step (default 15)
• AllowAnySurface — place on walls/ceilings/slopes (default true)
• AlignToSurface — align ghost to the aimed surface (default true)
• DebugLogging — log rotation changes to BepInEx

Notes

• Client-side only
• Still respects no-build zones, private areas, and biome restrictions
• Works best on rotatable hammer pieces

Changelog

0.3.7

• Change default reset key from R to J (R stows the hammer in vanilla).

0.3.6

• Skip Flip It rotation on prefab/blueprint placement ghosts (PrefabHammer, PlanBuild, etc.) so leftover tilt does not rotate entire saved builds.
• Clear stored pitch/roll when a prefab ghost is active.

0.3.5

• Add configurable reset key (default J) to return the current piece to vanilla orientation.
• Clarify rotation step config: set MatchVanillaYawStep = false and RotationStepDegrees = 90 for 90-degree steps.

0.3.4

• Reset pitch, roll, and vanilla yaw when switching to a different build piece.
• Skip surface snap and snappoint search while Shift or Ctrl is held so rotation does not jump mid-adjustment.
• Add SuppressSnapWhileRotating config option (default on).

0.3.3

• Keep vanilla placement until Shift/Ctrl tilt is used (fixes automatic rotation when stacking walls).
• Surface alignment and any-surface placement only apply after intentional pitch/roll input.

0.3.2

• Fix floating placement on ground and gap from walls by using vanilla collider snap instead of bounds offset.
• Only reposition the ghost when bypassing vanilla surface restrictions.

0.3.1

• Fix wall attachment validation and green ghost highlight.
• Temporarily relax restrictive piece flags during ghost update.
• Default rotation step matches vanilla (22.5 degrees).

0.3.0

• Add Ctrl+scroll roll (Z axis) and Shift+scroll pitch (X axis).
• Add surface alignment for walls, ceilings, slopes, and terrain.
• Add AllowAnySurface to relax vanilla surface placement restrictions.

0.2.0

• Fix Shift+scroll tilt by replacing placement ghost quaternion generation (same approach as PerfectPlacement).
• Read scroll via Unity mouse axis instead of only ZInput accumulation.
• Log DLL timestamp on load so you can confirm the latest build is active.
• Add optional DebugLogging config entry.

0.1.0

• Initial release: Shift + scroll horizontal-axis placement tilt.
