Mar Mar's Crops Growth Detector
by MarMarDev
Mar Mar's Crops Growth Detector adds a machine that reads how far crops have grown and sends a redstone signal once they reach the chosen age.
What it does
The machine watches crops placed in its range and emits a redstone signal depending on their age, which lets farms be automated around harvest time. Players on Forge or NeoForge can add it to existing farms without changing the crops themselves. The mod needs no extra library, and it runs on client and server, so both the server and every player need it. Files cover 1.20.1, 1.21 and 1.21.1, with 1.0.0 for 1.21.1 as the latest NeoForge file and 1.0.0 for 1.20.1 as the latest Forge file.
The code is open source under the MIT License, and public links include the source code. Harvesters can be triggered at the growth stage the player sets, so the machine fits farms of any size.
