Create a Minecraft tycoon plugin for Paper/Spigot (latest stable version) using Java. Core game concept: Players start on their own tycoon plot with a single mineable starter block. When they hit this block with a pickaxe, it gives them money. They use that money to unlock and expand a conveyor-based tycoon system. Main gameplay loop: 1. Starter block: - Each player starts with 1 starter block on their plot. - Hitting the block with a pickaxe rewards money. - The block should regenerate automatically after a short delay. - Only the plot owner (or allowed teammates if teams are supported) can use it. 2. Droppers: - Players can buy droppers using in-game money. - Droppers spawn display blocks / fake blocks / custom items that players cannot interact with or pick up. - These dropped blocks should visually fall onto a conveyor belt. - Blocks move along the conveyor automatically until they reach the end. - At the end of the conveyor, the blocks are sold automatically.
