Placer
by Brunixon.2
Placer is a NeoForge technology mod that adds a vanilla-styled block which places a block in front of itself, in the style of a dispenser for building.
What it does
Placer adds a new block in the vanilla style. Once it is given a block to face, it places that block in front of it. Its effect is most visible in automated farms, where a Placer set in front of a sapling or a block sets up the next piece of a build without a player standing there. The mod targets Minecraft 1.21.1 on NeoForge, and it runs on the client and the server, so both sides need it. The code is not open source, and the mod is released under All rights reserved, although its source code is publicly available.
Key features
Vanilla-styled placer block
The Placer block looks and crafts like other vanilla blocks, so it fits into an existing survival build.
Places the block it faces
A Placer puts a block in the space in front of it, which lets it fill rows or columns in a build.
Automatic tree farms
A Placer set against a block can plant saplings one after another, which supports automated tree farms.
