Builder's Hammer
by Goby56
Builder's Hammer is a Fabric hammer item, a copper tool that lets players change properties of placed blocks and save presets of block states.
What it does
Builder's Hammer adds a copper hammer made for survival play, positioned as a more balanced alternative to the debug stick. Left clicking on a block changes a property depending on where the player is looking, and sneaking while left clicking cycles through a predefined property in the chosen direction. Only some blocks have properties that can be changed with the hammer, and the author lists supported blocks in the project. Holding the hammer and using either left or right click works for these actions.
Right clicking a block saves its block state as a preset, and left clicking with a saved preset applies that state to other blocks. Sneaking with a right click removes a saved preset, which lets players keep editing a block state afterward. The block is highlighted green while a preset is being saved and red while one is being removed, and a small line of text above the hotbar reports what changed.
Servers that run it need every player to install it too. Builder's Hammer is published for Fabric only, with a single release line and a Fabric API dependency. It is open source under the GNU General Public License v3.0 only, and the project has public links for its source code and issue tracker. The author asks for suggestions of blocks to add over the issues page.
