Wtf does this do

RTS Building is a Minecraft mod that replaces the usual first-person building experience with a top-down view, similar to how you might manage a base in a strategy game. Instead of running back and forth between storage chests and construction sites, you open a building panel that shows your inventory, scans nearby storage, and lets you place blocks directly from above without moving your character at all. The core problem it addresses is the repetitive loop that comes with large builds: walk to a chest, grab a material, walk to the build site, place a block, walk back, repeat. The mod reduces that friction by letting you browse available materials from the top-down panel and click to place them where you want. You can still interact with the world normally while the panel is open, so you are not locked out of other actions. The mod also adds a larger hotbar so more blocks and tools stay visible at once, reducing how often you need to dig through storage to find a specific material. There is an optional skill tree in the configuration file that can be enabled to let players unlock functions gradually. The mod is currently in beta. The most complete and tested version targets Minecraft 1.21.1 using the NeoForge loader, and has been used extensively in the modpack ATM 10 To the Sky. A Minecraft 1.20.1 version on the Forge loader is available on a separate branch and has received lighter testing. Building from source requires Java 21. The license is LGPL-3.0 for releases starting from version 1.0.3-beta. Earlier releases were distributed under different terms.
