[Mod] Hoppers, chutes and sorters [hopper]

[Mod] Hoppers, chutes and sorters [hopper]

Postby FaceDeer » Sat May 05, 2018 4:32 am


Based on jordan4ibanez's original hoppers mod, optimized by TenPlus1 and FaceDeer, with chutes and sorters by FaceDeer

Hoppers are nodes that can transfer items to and from the inventories of adjacent nodes. The wide end of a hopper is its "input" end, if there's a chest or other compatible container it will take one item per second into its own internal inventory. It will also draw in items that have been dropped here. The narrow end of the hopper is its "output" end. It will attempt to inject items into a compatible container located at its output end. If there's no compatible container and the hopper's "eject" mode has been enabled it will instead dump the items out into the world.

The location of a hopper relative to a furnace determines which inventory slots the hopper will affect. A hopper directly above a furnace will inject items into the furnace's input slot. A hopper to the furnace's side will inject items into the furnace's fuel slot. A hopper below the furnace will pull items out of the furnace's output slot. Hoppers cannot inject items into inappropriate slots; non-fuel items will not be placed into the furnace's fuel slot and non-cookable items will not be placed into the input slot.

Also included in this mod are a "chute" node and a "sorter" node. These allow for items to be routed over short distances and distributed in sophisticated ways.

A chute simply moves items into adjacent nodes. You'll need to use a hopper or sorter to inject items into it to move along. A screwdriver is a useful tool for getting chutes aimed correctly.

A sorter has two different outputs. Its inventory has a "filter" grid; place items in this grid to set the sorter's filter. Items that match the filter will be sent out the output with the large arrow and other items will be sent out the output with the smaller arrow. A "filter all" option will cause the sorter to attempt to send all items in the direction of the large arrow and then if that fails send them in the direction of the smaller arrow. This allows you to have an "overflow" storage should the sorter's primary target fill up, or when used in combination with a selective container (like the furnace's fuel slot, for example) it allows the target inventory to do the filtering for you.

Hoppers have the same permissions as the player that placed them. Hoppers placed by you are allowed to take items from or put items into locked chests that you own, but hoppers placed by other players will be unable to do so. A hopper's own inventory is not not owner-locked, though, so you can use this as a way to allow other players to deposit items into your locked chests.

Advanced settings

This mod has several configurable settings found in the advanced settings menu.

  • Hopper texture size: can be set to 16 pixels (matching most standard Minetest node textures) or 32 pixels
  • Single craftable item: When enabled (the default) hoppers are crafted as a single item and then select whether the output has a 90-degree turn to the side based on how you place it. When disabled you can craft straight and bent hoppers as separate items.
  • Eject items button: this can be used to remove the "eject items" button from hoppers, if it is not desired.

If other mods wish to make containers compatible with hoppers, there is a public API documented here.

the api is probably the easiest way to add item transport to a custom block

On one of the factions servers, the hoppers keep on getting jammed up due to a glitch/bug in the code.

Could you file an issue over on GitHub with some details about how the bug is happening? There's not much I can do to hunt down what's specifically wrong with just "hoppers keep getting jammed", I need some specifics about what circumstances are causing them to be jammed.
