Rotator
by wisx
Rotator lets players set the facing direction of blocks such as observers, pistons, dispensers, hoppers and droppers when they place them.
What it does
When a player places one of the supported blocks, Rotator sets its facing direction instead of leaving it to the default placement rules. The supported blocks include observers, sticky pistons, dispensers, hoppers and droppers, so builders can aim redstone parts without rotating them afterwards.
The mod has a main toggle that turns the rotation behavior on or off, and the default value and default hotkey are set in its options. Its configuration is handled through the Malilib and ModMenu interfaces, so players change settings in the in-game menus rather than editing files.
Rotator is a Fabric mod for Minecraft 1.20.1 only, and it needs Fabric Loader to run. It runs on the client and the server, so both sides need it installed. The code is released under the MIT License and is open source, with public source code and an issue tracker.
Key features
Directional placement
Supported blocks take a facing direction at the moment they are placed, which speeds up redstone builds.
Covered block types
Observers, sticky pistons, dispensers, hoppers and droppers all follow the placement direction set by the mod.
Main toggle
A single switch enables or disables the rotation behavior without removing the mod from the game.
Hotkey and defaults
A default hotkey and a default value are configurable, so the behavior can be adjusted from the options menu.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Redstone builds
Players laying out piston and observer contraptions can place parts in the intended direction on the first try.
Item transport
Hoppers and droppers can be aimed while placing them, which helps with routing items through a build.
Who it’s for: Players and server owners who build redstone machines or item systems on Minecraft 1.20.1 with Fabric. Because both sides need the mod, a server owner should install it on the server and players should install it on their clients.
How it compares
Smart Placement is a Fabric mod for 1.21 – 1.21.11, client-side only and released under the MIT License. Super Pistons is a Fabric mod for 1.20.1 – 1.20.4 that runs on client and server, also under the MIT License. Extended Dropper is a server-side only Fabric mod for 1.19 – 1.21.6 released under the CC0 1.0 Universal license, so it covers droppers in a different way.
