Enchantment Table Boosting

How is it calculated?

About the Enchantment Table Chances

First, all the enchantment books in all bookshelves around the table is counted, an occurrence number and average level is obtained.

Then, the plugin pull all of them into a list of enchantment options. So [Sharpness:O=4,L=3] and [Power:O=2,L=1] wlll be

Sharpness III
Sharpness III
Sharpness III
Sharpness III
Power I
Power I

on the list.

Then, the plugin will add nulls to the list to match the number of total slots for a complete level 30 enchantment table. The amount of nulls add to the list is

NumberOfInventoryRowsInABookshelf x 9(9 slots per row) x 15(Level 30 needs 15 shelves) - SizeOfList(The size of the list in the last step)

Then, the plugin will get the max chance defined in the config and add more nulls to the list, the amount is addition nulls added is as follows

SizeOfList * ((ChanceInConfig / 100) ^ -1) - SizeOfList 

Finally, the plugin will choose one random item from the list to put into each of the 3 options displayed in an enchantment table, if the item chosen is Sharpness IV then it will be Sharpness IV; If the item chosen is null then the vanilla randomly chosen enchantment will be used.

(Note that special enchantments that cannot be obtained in an enchantment table will not be considered)
