Knapsacks (backpacks on steroids) - Basically similar to betterbacks with many more features for both server owners and players. I’ve been working on this and the beta is completed, however it’s only compatible with 1.7.8 - 1.7.10. The plugin features similar crafting mechanisms as betterbacks did, but also has a lot of customizing options for the players as well as realistic features. A few examples would be the max. weight a Knapsack can carry, the ability to actually name your Knapsack and keep that name for the life of the Knapsack. The ability for server owners to limit how many Knapsacks of different sizes (currently up to 54 slots), a player can have as well as the total Knapsacks overall a player can have (two different animals there). Additionally, Knapsacks has a stealth / thief feature that allows server owners to define how players can interact with Knapsacks, such as stashing them in chests or dropping them and and another player comes along and wants to open that sack. Whelp he can but based on thief settings, as well as block settings the player defines, the player opening the sack and attempting to steal from it could be jailed and/or penalized. etc. etc. etc…
I will be porting this over to Sponge as soon as the SpongeAPI is released. Meanwhile I will be uploading the release of Knapsacks to the current bukkit community so those who still use bukkit (a lot) can enjoy.
Oh BTW. The list of plugins to port of from bukkit to Sponge is ENORMOUS!!! Wow!!! That’s a lot of time!
