Redstone Helper
by Bumer-32
Redstone Helper is a Fabric utility for building redstone circuits, with auto-placement of redstone components and a bit calculator.
What it does
Players set up redstone circuits with a set of placement tools. Pressing B activates auto-wire mode, which can be switched on or off and set as the default after a world loads. While it is active, redstone blocks, repeaters and comparators are placed in a row, and a comparator variant places redstone comparator blocks. One placement option lays down a redstone block and then 15 repeater blocks.
Pressing N opens a calculator window that converts numbers between bits, hexadecimal and integers. The interface can be restyled with dark panels and a blurred background in place of the vanilla translucent one, and the language can be changed. Players who hold N's rebind can move the keys in settings.
Redstone Helper requires Fabric API, Fabric Language Kotlin and oωo (owo-lib). Mod Menu and WorldEdit are optional. The mod is open source under the Apache License 2.0 and is published for Fabric only, in seven game versions 1.20.4 – 1.21.4, with 0.2.5.5 for 1.21.4 as the latest file. Either side can run it, and neither needs it.
