SpigotVIP SpaceStacker // Spawner Stacking | Spawner Upgrades | Item Stacking | Mob Stacking 1.8

The Gist:
This plugin allows a simple and useful stacking/upgrading experience, this plugin reduces lag on servers by around 40% (Entity Lag). Servers this was made for are ones with game modes that are heavy on spawning mobs for example SkyBlock. This plugin also allows players a more unique experience with spawner upgrades where you upgrade the drops that the mob killed drops. This is an ever-expanding plugin and will grow with time if you would like to see something let me know and I'll see about adding it!

Dependencies:

• Vault
• Holographicdisplays

Commands:
/spacespawners give <player> <entitytype> <material> [amount] : This command gives the player specified the spawner that is input must have the "spacespawners.admin" permission.

/spacespawners reload : This command reloads all the upgrade types as well as settings/ messages once again requires the "spacespawners.admin" permission.

Permissions:
spacespawners.admin : This is currently the only permission available as I feel having too many permissions is a nuisance.

Screenshots:

Above: shows an upgraded Zombie as well as spawner
Below: shows the default GUI for the SpaceStacker upgrades this is fully configurable (thankfully)

Everything that is text is configurable


The hovering item and text above spawners requires Holographic displays

FAQ:
Q: Will you support 1.8?
A: Refer to this link https://www.google.com/search?q=whe...0.0j69i57j0.6889j1j7&sourceid=chrome&ie=UTF-8 The short answer is no to a degree, the main core features work, however, there are features that are 1.9+

Q: Can you just give this to me for free?
A: Short answer, No. The long answer is maybe but would take ALOT.

Q: I removed the amount and upgrade from the lore and its broken.
A: The plugin isn't broken, I don't want to use hidden utils to save upgrades and amounts to the item nor do I know if that's even persistent after restart so that's why the comment is there saying those two must be included in the lore. <3

Q: Will there be a developer API?
A: Yes, there will be one I just need to get around to putting it together!

Q: Why don't the spawner upgrades work with my island top plugin?
A: The API isn't out or you aren't using my Island Top plugin (Not currently released but will be very soon)

Q: Will you work for my server?
A: No, but thanks for asking.

Q: Why isn't this a spawner provider for ShopGUIPlus?
A: I fiddled around for longer on trying to get that to work than actually making the plugin itself. If I figure it out I'll update this. <3
