Crops & Blocks Faster Crops ⚡ Spawner Control ⚙️ Placement Limits GUI ✅ | 1.21.x
Crops & Blocks boosts crops inside the natural ticking area — no chunk loading, TPS‑friendly. All changes apply server‑wide (all players, all worlds)…
⬇ Download on SpigotCrops & Blocks boosts crops inside the natural ticking area — no chunk loading, TPS‑friendly. All changes apply server‑wide (all players, all worlds): per‑crop growth control, precise spawner rates ( true 200–800 at 1.0×), and per‑player placement limits — all managed in a clean GUI (/cnb).
CROPS — WHAT CAN YOU DO
- Growth Enabled — global switch for crop control. When off, vanilla growth is fully blocked for supported crops (Wheat, Carrots, Beetroots, Sugar Cane).
- Per‑crop multipliers — individual multipliers per crop:
- 1.0 — pure vanilla (no change).
- > 1.0 — speed up: the booster adds smooth extra growth only inside the natural ticking area (player simulation‑distance). No chunk loading.
- < 1.0 — slow down: vanilla growth is probabilistically throttled (via BlockGrowEvent) to avoid spikes.
- ≤ 0.0 — fully block this crop (usually better to use the per‑crop Enabled switch instead).
- Per‑crop Enabled — hard ON/OFF per crop, independent of the multiplier. Great if you want to completely disable, e.g., sugar cane.
- TPS‑friendly by design — the booster operates only where the server already runs ticks (the natural player simulation‑distance). No chunk tickets, no forced loading.
- Column‑based scan near the surface targets real crops (or farmland with a crop above), so the hit rate is high and results are visible.
- Sugar cane has dedicated logic and respects the vanilla height limit (up to 3 blocks).
- The booster never touches unloaded areas — it acts only in chunks that are already loaded and ticking.
- Per‑player crop caps (Wheat, Carrots, Beetroots, Sugar Cane) via Player Settings → Crop Caps.
- Use for rank perks or to limit farm scale per player — values act as per‑player overrides you can manage from the GUI or commands.
- For small servers: start at 1.0; when you want a visible effect, set 2.0–3.0 only on the crops you care about.
- If crops sit under a roof and hits seem low, raise column-scan.depth or surface-offset slightly.
- For testing, run /cnb boosterdebug on → show to see Crop hits / Eligible / Age‑ups.

SPAWNERS — WHAT CAN YOU DO
15s Timelapse with 5.0 multiplier boost.
CROPS per-type disable function
- Global enable — one switch to allow or block all spawners server‑wide (all players, all worlds).
- Global rate — set the overall spawn rate multiplier. 1.0× = true vanilla timing (200–800 ticks). Higher = faster cycles, lower = slower.
- Per‑entity rates — override the global rate for specific mobs (inherit or custom).
- Per‑entity enable — enable/disable individual spawner types (inherit or custom).
- Burst protection — a small inter‑tick cooldown ensures spawns don’t “burst” across ticks while still allowing same‑tick batches from one cycle.
- GUI‑first — manage everything in the Spawners page via /cnb; debug tools included.
- At 1.0× global rate, spawners are aligned to the true vanilla baseline: 200–800 tick delay range (with vanilla core params set consistently).
- When you change the rate, min/max delays are recalculated from a stable baseline — if the current delay falls outside the new range, it’s reset to a random value inside it (no weird spikes).
- A minimal between‑tick cooldown prevents cross‑tick bursty behavior but does not cap the normal same‑tick batch from a single spawner cycle.
- Settings are applied to spawners in currently loaded chunks; on chunk load, all spawners inside the chunk are automatically re‑applied. No chunk loading is performed.
- When a type or global spawners are disabled, the plugin does not mutate spawner fields — the listener simply cancels those spawn attempts.
- /cnb spawnerdebug on → show — displays the nearest spawner’s min/max delay, effective rate, vanilla params, and attempt counts (proves the 1.0× = 200–800 baseline).
- /cnb spawnerdebug reset — resets the local window counter for the nearest spawner.
Introduction to SPAWNER GUI
15s Timelapse with SKELETON spawner with value 5.0
- Global limits switch — turn the system ON/OFF server‑wide (all players, all worlds).
- Per‑block caps (server defaults) — set per‑player limits for spawner, hopper, slime_block, redstone.
- Per‑block enable — fully allow/deny placement of each block type (independent of limits).
- Per‑player overrides — give or remove custom caps for specific players (via GUI or commands) — perfect for rank perks and rewards.
- GUI‑first — manage everything in the Limits page via /cnb, or automate with commands.
- On place, the plugin checks the player’s effective cap for that block type; if the count would exceed the cap, placement is denied with a clear message.
- Counts are maintained per player and type, and decrease on valid block break.
- Ownership moves/cleans up correctly in common edge cases:
- Pistons moving slime_block — ownership is transferred.
- Explosions breaking controlled blocks — counts are decremented.
- Data is saved to disk and restored on startup; all limits apply across all worlds.
- Global enable and default caps affect everyone on the server, across all worlds. Per‑player overrides supersede the defaults for that player only.

Compatibility
- Spigot/Paper 1.21.x • Java 21
- No NMS, no chunk tickets; plays well with performance plugins.
Installation
- Drop the jar into /plugins, restart.
- Use /cnb to configure; edit config.yml for advanced options; /cnb reload to apply.
FAQ
-
What is the “natural ticking area”? — The player’s simulation‑distance where the server already runs ticks.
-
Does it load chunks? — No. It only scans chunks that are already loaded.
-
How to make crops faster? — Set per‑crop multiplier > 1.0 (e.g., 2.0).
-
How to slow crops? — Set multiplier < 1.0 — we safely throttle vanilla growth.
-
Is it TPS‑friendly? — Yes. It never expands ticking beyond the natural area, and defaults are conservative.
Support
Free to use. If this helps your server, consider supporting via PayPal (click here).
Feedback and ideas are welcome — I actively maintain and improve the plugin.
Ready? Drop the jar, run /cnb, and you’re done.
