CustomSpawners

Build more than a mob farm
CustomSpawners brings spawner stacking, configurable tiers, custom loot and an in-game shop together in one Minecraft plugin. Create mixed mob farms, reward players for mob kills, or design generators that produce items, place blocks and run console commands.

Built for survival, Skyblock, factions and economy servers, with English messages, native holograms and in-game configuration menus.

Features

• Spawner stacking: combine matching spawners and keep their quantities in one block.
• Omni spawners: combine multiple types and tiers, then manage each component from a menu.
• Configurable tiers: buy stack units or tier upgrades with money or experience levels.
• Four generator modes: entities, items, blocks and console commands, including mixed outputs.
• Spawner shop: paginated browsing, configurable prices and purchases of 1, 10 or 64 items.
• Timed boosts: buy extra output for a spawner or grant timed/permanent owner bonuses.
• Conversion: change spawner types using money or spawn eggs.
• Silk Touch pickup: configure collection requirements, drop chances and whole-stack pickup.
• Custom mob loot: quantities, chances, item names, lore, experience and command rewards.
• Kill rewards: guaranteed milestones, random spawner rewards and player statistics.
• Farm conditions: biome, height, light, nearby players, entity caps, storms and ground materials.
• Server controls: redstone pause, no-AI mobs, chunk/player limits, proximity combining and blacklists.
• Native holograms: show type, tier, stack count and pause reasons without an external hologram plugin.
• In-game editing: nested definition/settings menus with validated YAML values.
• Custom recipes: configurable shaped crafting recipes with player permission checks.
• Maintained data: persistent item metadata, ordered state saves and a backup of the previous state.

Quick start

1. Download the release JAR and put it in your server's plugins folder.
2. Start Paper, then configure the generated CustomSpawners files.
3. Give yourself a spawner, place it and right-click to open its menu.

Right-click a spawner with another tagged spawner item to combine them. Use a spawn egg to convert it. Mine with Silk Touch to collect it; sneak to collect the whole mixed stack when enabled.
