Flopper for Minecraft 1.21.11


For early fluid automation, Flopper is an excellent choice — a mod that adds the Fluid Hopper block, functioning similarly to an item hopper. It can extract fluids from above, from tanks, or from the surrounding world, and transfer them elsewhere, prioritizing interaction with tanks.

The device does not have a complex interface: when clicked, it displays its current contents, and the fluids are visually visible inside the block. Its operation can be disabled with a redstone signal, and the transfer speed or interaction delay can be configured. It is a convenient and flexible tool for building basic fluid transport systems without complicated machinery.

How to install the modification:

First step: download and install Forge.

Second step: download the mod file.

Third step: copy Flopper mod package to the .minecraft/mods folder (if it does not exist, install Forge again or create it yourself).
