About:

SpawnerLegacy implements fully customisable spawners.
Plugin features:
✦ Spawners have 6 different upgrades - range (required player distance from the spawner), delay (time between each spawning), amount (entity amount that will be spawned), limit (maximum amount of entities near the spawner for it to spawn), wisdom (entity's dropped xp increasement) and looting (entity's dropped item increasement).
✦ All spawner spawn requirements can be fully changed to fit your needs in the requirements.yml file.
✦ Spawner holograms show data about each spawner - entity type and stack size, condition warning and spawner spawn time countdown.
✦ Spawner breaking supports silk touch (or other enchantments), allows to change breaking chance, xp drops and much more.
✦ Stacking allows players to add multiple same-type spawners into one, increasing it's spawning rate and improving server performance. (disabled by default)
✦ Spawners can be switched on and off in the upgrade GUI, enabling players to stop entity spawning at any moment. (disabled by default)
✦ When charges are enabled the spawner requires for the player to purchase spawn charges for the spawner to spawn. (disabled by default)
✦ Spawnable entity limit enables spawners to spawn only a certain amount of entities before being destroyed. (disabled by default)
✦ This plugin provides other options, such as, spawner type changing with a spawn egg, empty spawners that let players to switch the spawner type at any time using a spawn egg, chunk limits, fully customisable pricing, entity modification and much more in the configuration.yml file.
✦ Spawners can be purchased and sold using the built-in shops that can be customised in the shop.yml file.
✦ All plugin texts can be fully changed in the language.yml file.
