Capability Proxy

by rubensworks

Capability Proxy lets a block with no direct access to another block's capabilities reach them through a placed proxy block, extending the sides a block API can be queried from.

What it does

Capability Proxy extends block capability APIs so that one target block can be accessed from more than one side. A regular proxy communicates with its neighbours, while a ranged proxy reaches a target up to 16 blocks away, a range that is configurable. Each proxy is pointed toward the block whose capabilities it should expose, and kinds of capability such as items, fluids and energy can then be pulled or pushed through it. Interactions are forwarded as well, including opening a block's GUI. A block that is inactive in its current state is not a valid target until it becomes active again. Chaining proxies adds more available sides when five are not enough.

The mod also covers entities and items. Entity and item capability proxies let entities be interacted with through a block, and an item inserted into a proxy interacts with the items of the block behind it. Examples in the author text include routing pipe items dropped into a Shulker Box, and an example proxy holding a tank of fluids that is piped out using Integrated Tunnels. Capability Proxy requires Cyclops Core, and it is published for Fabric, Forge, NeoForge and Quilt, with files for 1.18.2 – 26.3 and 19 release versions. A server running it needs every connecting player to have it too. The code is open source under the MIT License.

Key features

  1. Regular and ranged proxies

    Regular proxies reach their immediate neighbours, and ranged proxies reach targets up to 16 blocks away, configurable in the config file.

  2. Pointed proxy targets

    A proxy is aimed at the block whose capabilities it should expose, so a single target can be reached from additional sides.

  3. Chained proxies

    Proxies can be chained to reach further sides and blocks, beyond the five extra sides a single proxy gives.

  4. Entity and item proxies

    Dedicated proxies let entities and items be handled through a block, such as pipe items dropped into a Shulker Box.

  5. Forwarded GUI interactions

    Interactions are forwarded through the proxy, including opening the GUI of the block behind it.

Questions

Does Capability Proxy need Cyclops Core?

Yes. Cyclops Core is a required dependency and must be installed alongside Capability Proxy on every loader.

Does Capability Proxy need to be installed on the server?

Yes. Installation covers the server and each player's game.

Why does a proxy not work on some blocks?

Some blocks have no capabilities by default, such as the Composter, so Common Capabilities is needed to add them. A block in an inactive state is also not a valid target.
