This would be a plugin and a seperate tool program. A simple GUI would allow you to name items and create item (and mob) tables, which could then be exported as a file to the plugin, which then calculates area drops, set bonuses, mob spawn areas. --Area Drops-- This is a defined area that allows certain items to be dropped by mobs in it. Configurable block protection. /plugin area define [name] /plugin area add [name] [item table] /plugin area [active/inactive] --Set Bonuses-- Fairly self explanatory, it would just be that having a full set of one type of armor would give a small bonus, such as a small speed or mining increase. A command would list sets and their bonuses. /armorbonus --Mob Spawn Areas-- Similar to area drops, within an Area Drop area, select a single block to be a mob spawn point. Then name the monster(s) that it will spawn and the maximum amount. A config file would handle the respawn time. The monsters, when spawned, would have randomized armor and drops based on the table that was assigned to the Area Drop it is in. /plugin mob [monster] (additional monsters) [max spawn] then right click to select the block. Destroy the block to remove it, configurable spawnpoint protection. If you think you can/will make this, tell me, I have an idea in mind of the Tool layout, and I will make an image if neccessary. Thanks for reading!
