Per-block-type control over Minecraft's duplication exploits, with an in-game GUI. Paper 1.21.x.
Paper only exposes a single global allow-piston-duplication switch — all dupes on, or all dupes off. DupesPlus adds fine-grained per-type control for TNT, sand, rails, carpet, and the end-portal gravity-block dupe, all from one chest menu.
Features Five toggles, one GUI — TNT · Sand · Rails · Carpet · End Portal Per-dupe throttles — max-per-cycle cap and per-position cooldown-ticks Rail sub-toggles — powered / detector / activator rails independently Comment-preserving edits to paper-global.yml — DupesPlus writes the two unsupported-settings for you and warns when a restart is needed Tab-completed /dupe chat commands Optional op broadcast on every toggle Zero-allocation fast path — the piston listener early-returns when nothing is throttled, so no perf cost with defaults No external deps · no reflection · no NMS · no telemetry
