Item Access Restrictor | 物品存取限制器
Introduction
This is a Minecraft mod that adds a functional block: Item Access Restrictor. It has no inventory itself, but when attached to a container, it can serve as the surface for inserting and extracting items. You can configure input blocking, retain a certain number of items, etc. You can also use a comparator to read redstone signals.
Configurations
| Name | Additional Information | Scope | Default Value |
|---|---|---|---|
| Blocking input if target is not empty | Disabled slots and retained items are not included in the target. | Enabled, Disabled | Enabled |
| Blocking input if receiving redstone signal | None | Enabled, Disabled | Enabled |
| Comparator Output Mode | When set to 'Only count effective items and slots', it uses the same calculation method as typical containers like chest or hopper, with a minimum of 0 and a maximum of 15. | Only count effective items and slots, Same with facing block | Only count effective items and slots |
| Input Stacking Limit | Once the number of items inserted in a slot reaches the configured limit, no more items can be inserted to this slot; It will affect the calculation of the redstone signal output by a comparator. | Unlimited, 1–64 | Unlimited |
| Number of items retained | Once the number of items in a slot is reduced to the configured number, items can no longer be extracted from this slot; It will affect the calculation of the redstone signal output by a comparator. | No retain, 1–64 | No retain |
| Enable or disable insertion and extraction of the slot | When the number of slots facing the container changes, it will automatically switch back to the enabled; Disabled slots cannot be inserted into or extracted from, and they will not be included in the calculation for comparator output redstone signals. | Enabled, Disabled | Enabled |
