About PlanBuild

From Thunderstore

PlanBuild enables you to plan, copy and share your building creations in Valheim with ease. Includes terrain tools and immersion items.

PlanBuild

> ### New in version 0.20.0 > > __Mirror blueprints__ while placing them with __H__, or create a mirrored copy with __Ctrl + H__. Angled pieces and roof corners are turned to match their mirror image. > __Rectangle marker__ for the terrain and paint tools: change its width and depth separately with __Ctrl + Shift + Scroll__ and __Alt + Shift + Scroll__. > * __Slopes__ with the terrain tool: tilt its marker with __Ctrl + Alt + Scroll__, the marker shows the finished slope before you build it. > > More new features and bug fixes are listed in the changelog. > > ### Since version 0.19.0 the HookGenPatcher is no longer needed > > All hooks now use Harmony, so __HookGenPatcher (MMHOOK) is no longer a dependency__ and can be removed if no other mod requires it.

PlanBuild enables you to plan, copy and share your building creations in Valheim with ease. The mod adds two new tools to the game. The __Plan Hammer__ is used to plan your creations before actually gathering all the materials. When you are happy with your build, you can add the required building materials one by one or use a custom totem to automatically build the pieces for you. The __Blueprint Rune__ lets you copy, save or delete your creations as a single building piece which can also be shared with other players using the mod and also includes terrain modification tools for quick and more precise terraforming without using the Hoe or Cultivator.

Planning

Plan mode

Introducing a new item, the __Plan Hammer__, which can be crafted from a single log of __wood__ and the blessing of Odin shining upon you.

PlanHammer

Plan the construction of pieces without the need to gather the resources first. Anyone can add the required resources to the planned structure later and finish the construction after it was placed.

The __Plan Hammer__ is compatible with custom piece tables from other mods. All custom pieces will be incorporated into the runes table for the planned pieces. You still need a __Hammer__ and the required crafting station to finish the construction.

Planned pieces that are __unsupported__ can not be finished. These pieces are also slightly more transparent so you can see what is and isn't supported. The planned pieces themselves do not require support, so you can build forever (if you can reach far enough).

Real pieces also snap to the planned pieces, so you could even use them as __spacers__ or __rulers__.

Plan Totem

Plan Totem

Build a __Plan Totem__ near your planned structures to be able to add resources in a centralized location for all individual pieces on the plan.

It will also protect existing structures. Any piece that is destroyed _(not removed by the Hammer)_ will be replaced with a plan for that same piece in the same place!

This needs to be built with the vanilla Hammer tool and costs you __1 Wood__ and __1 Grey Dwarf Eye__.

Skuld Crystal

Skuld Crystal

Includes the __Skuld Crystal__, a wearable item that removes the shader effect from the blueprints, so you can see what the construction will look like when completed.

Create it from a single __Grey Dwarf Eye__.

__Watch your step!__ The pieces are still not really there, and will not support you!

Blueprinting

Blueprint mode

Introducing a new item, the __Blueprint Rune__, which can be crafted from a single __stone__ and festering willpower given to you by the gods.

BlueprintRune

Copy existing structures into __Blueprints__ and rebuild them as planned or regular pieces all at once. The blueprints are saved in and loaded from the filesystem as __.blueprint__ files. Also supports __.vbuild__ files (you can load and build your BuildShare saves with this mod)! After switching to the blueprint mode, the piece table of the Blueprint Rune offers three different categories:

Tools

Blueprint tools

The Blueprint Rune comes with a handful of tools to handle blueprint creation and terraforming.

  • __Create new Blueprint__: Directly create a blueprint from a selection indicated by the circle marker.
  • Hold __Ctrl__ to highlight all pieces which will be saved into the blueprint
  • Hold __Alt__ and click to include vanilla snap points in your blueprint (without it only snap point markers are converted to snap points)
  • Use the __Scroll Wheel__ to change the selection radius
  • Use __Shift + Scroll__ to adjust the camera distance.
  • __Add to selection__: Add pieces to the current selection. Currently selected pieces will be highlighted in green. Per default only the hovered piece will be added to the selection. You can use various modifiers to change that behaviour.
  • Press __Q__ to quickly switch to the "Remove from selection" tool
  • Hold __Alt__ and click to add all connected pieces. This uses a flood fill to find connected pieces.
  • Hold __Ctrl__ and click to add pieces in a radius
  • Use the __Scroll Wheel__ while holding __Ctrl__ to change the selection radius
