Optional properties

Capacity

Name : capacity

Description :

A positive integer value that define the maximum number of item that you can put in the slot.

This does not override the item stack size (if you set the slot capacity to 100 items will still stack by 64 or less). This is used to decrease the available stack size, not increase it.

Example :

"filter": ["minecraft:diamond", "#minecraft:logs"]

The slot will accept all items but Minecraft diamond and items in the minecraft:logs tag.

Whitelist

Name : whitelist

Description :

A boolean, if true the filter property will act as a whitelist instead of a blacklist, meaning that the slot will only accept items specified in the filter property.
