Lets Build

A builder's hammer that never wears out, precision building with the hammer, and planting in rows and columns.

The mod speaks the game's language: German in a German game, English in every other one.

The builder's hammer

Never wears out. Not by having a huge durability number — by having none at all, so there is no bar quietly draining either.

Free building and flight while held. Equipping it switches on the game's own devcommands, debug mode, free placement and flight. Unequipping puts every one of them back.

Back, not off. If you had flight or free building on before you picked the hammer up, putting it away leaves them on. It restores what it found rather than switching things off, so it cannot cancel something you asked for yourself.

Flight ends when you land. Cutting flight in mid air would be a fall you did not agree to, so it waits for solid ground. Until then you build normally and can still fly.

A loose camera for building. With the hammer in hand, press P and the camera comes loose. Fly it with WASD, jump and crouch, and build exactly as you always do. Press P again, or put the hammer away, and the camera is back behind you.

It comes back if it was lost. The game throws away any item whose mod is not loaded when a character is loaded — one session in a mod profile without Lets Build, and the hammer was gone for good. The mod now remembers how many hammers you carried and hands back any that were lost that way.

Your normal hammer is untouched. This is a separate item, not a change to the vanilla one.

Precision building

With the hammer (the game's and the builder's hammer):

Key	What it does
H	Grid on / off
N	Grid size: 0.125 · 0.25 · 0.5 · 1 · 2 m
J	Rotation step: 90° · 45° · 22.5° · 15° · 5° · 1°
U	Snap to grid corners or to cell centres

• With the grid off, building is exactly the game's own: its 22.5° rotation step, and N, J and U do nothing. Your choices are kept for the next time you switch it on.
• The keys are shown lower right, in the game's own key hint style.
• The grid lies on whatever you aim at: floors and terrain, and along walls too.
• It is anchored to the world, so pieces placed hours apart still line up.
• The game's own snap points still win when a piece clicks onto its neighbour. Hold the alternative placement key (Shift) to place freely, as always.
• The grid lies flat in the plane of the surface you aim at and never runs over anything else.

Planting

With the cultivator and a plant selected:

Key	What it does
↑ / ↓	More or fewer rows
→ / ←	More or fewer columns
H	Line up with the plants already standing: on / off
Shift + E	Pick everything ripe around what you pick — crops, bushes, beehives

• Exactly the spacing the game needs. The distance between plants is worked out from the game's own growth rule, so a grid is as tight as it may be and every plant grows.
• Red where it would not grow. Wrong biome, no sky, too little space, ground not cultivated — checked the way the game checks it, before you plant. The reason is shown.
• Continues existing rows in the direction they run.
• Every plant is paid for. Seeds, stamina, cultivator wear and farming skill count for each plant, exactly as if you had placed them one by one. If something runs out, planting stops there.
• Replant on harvest (off by default): the seed goes straight back into the ground.
• Growth in the hover text: how far a plant has grown and when it is ready; when a picked bush bears again.

More to plant

• Wild plants: raspberry, blueberry, cloudberry and lingonberry bushes, mushrooms, thistle, dandelion, smoke puffs and fiddleheads. What you plant is the game's own object. Only what a player planted can be taken away again, and the cost is not refunded, so nothing can be duplicated. Planted mushrooms and flowers grow back after picking (wild ones stay as the game has them).
• New saplings: ancient (swamp tree), yggdrasil shoot, autumn birch and ashwood.

Rules the server decides

Where crops and trees grow, whether they need cultivated ground, open sky and space, how fast they grow and what the wild plants cost — set on the server, synced to everyone.

Worth knowing

Required on the server and on every client. The new saplings are objects a player without the mod could not even see, and the planting rules come from the server. Jötunn checks this when you connect and says so if something is missing.

The hammer enables cheats. That is the point. Valheim marks a session that used devcommands, and achievements know about it.

On a server you need to be an admin for the hammer. Admin only is on by default.

Settings

All in dezzycode.valheim.letsbuild.cfg. Sections 1–4 are yours; section 5 is the server's and is synced.

Spawn the hammer by hand with spawn LetsBuild_Hammer.

Requirements

• BepInExPack Valheim
