This addon for my Redstone Tweaks Resource Pack adds power indicators to hoppers, droppers and dispensers.
With Minecraft 1.20.2, Mojang finally fixed hopper, dropper & dispenser blockstates. I have therefore merged this addon into Redstone Tweaks 2.4. It is no longer required and will not receive further updates.
Due to a limitation with Minecraft's code, this addon works best together with the Carpet Extra mod by gnembon. Once installed, simply run the following command in your world:
/carpet blockStateSyncing true
This ensures all blocks visually update correctly. In Multiplayer, the mod has to be installed on the server for everything to function properly.
Some of the textures are based on work from other creators. Go check them out!
