About this mod Author’s original text

CS Hammer Tweak

Adds Hammer compatibility for the original CastleStructures mod without modifying the original DLL.

What It Does

  • Injects CastleStructures pieces into the vanilla Hammer build menu
  • Injects CastleStructures pieces into BuildIt's Improved Hammer (_RKCustomTable) when BuildIt is installed
  • Adds config toggles for vanilla and improved hammer menus

Dependencies

  • BepInExPack_Valheim
  • Jotunn
  • RockerKitten-CastleStructures

Optional Dependency

  • RockerKitten-BuildIt

BuildIt is not required. If BuildIt is installed, the plugin can inject CastleStructures pieces into the Improved Hammer menu.

Install

  • Install the original RockerKitten-CastleStructures.
  • Drop CastleStructures.HammerCompat.dll into your BepInEx/plugins folder.
  • Start the game once to generate config.
  • Edit config toggles if needed, then restart the game.

Config

  • ShowInVanillaHammer
  • ShowInImprovedHammer

Config changes require a game restart.

Notes

  • This is a compatibility patch plugin. It does not replace or modify the original CastleStructures DLL.
  • Improved Hammer injection is skipped automatically if BuildIt is not installed.

Install & use Install: BepInEx plugin

  1. The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
  2. Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
  3. Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
  4. Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.

Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.

Install these first, or the mod will not work:
