Custom Fluids
experimental
intermediate
WARNING
Requires a basic knowledge of blocks, scripts, and commands, including permutations, events, properties, components, and the new execute command.
Creating fluids that are identical to vanilla fluids is not currently possible, but it is possible to make something similar. This template/tutorial is designed to assist you in creating a custom semi-fluid.
How Semi-fluids Work
Semi-fluids consist of five blocks: three blocks form the outer parts of the fluid, one block acts as the main source of the fluid, and the final block represents the falling part of the fluid. Additionally, execute commands are utilized to identify blocks and establish rules for the fluid flow. Throughout the remainder of this guide, semi-fluids will be referred to as fluids.
Source Fluid Block
Below is the source fluid block code. To replicate the json, copy and quick replace template with your fluid's name. When the source block detects air in its surroundings, it replaces it with the outer fluid block 1. If the source block detects air beneath it, it will also place a falling fluid block underneath.

Outer Fluid Block 3
Below is the JSON for the outer fluid block 3. To replicate the json, copy and quick replace template with your fluid's name. This block solely places the falling fluid block. Moreover, all fluid blocks check for the existence of at least one fluid block from a higher tier next to them. If none is found, the block deletes itself.

Falling Fluid Block
Below is the JSON for the falling fluid block. To replicate the json, copy and quick replace template with your fluid's name. If this block detects air below it, it will place another falling fluid block. However, if it detects another block beneath it, it will behave like the source fluid block.

Fluid Bucket
To pickup or place your custom fluid you need a custom bucket item. Although any item can pickup the fluid, your fluid can be customized to require this custom bucket. Below is the JSON for the custom bucket. To replicate the json, copy and quick replace template with your fluid's name.

Scripts
The fluids use a script to add the ability for the player to float/sink in the fluid. The script also adds fog. To add your fluid to the script, put the ID of your new fluids in the fluidsIDs string array.

Resources
To define the textures for the fluids you need to do two thing:
- Make a 16x16+ texture and in terrain textures copy/rename the "fluid_template" to "fluid_
your fluid name" - Make a texture and in item textures copy/rename the "template_bucket" to "
your fluid name_bucket"

If anything goes wrong, or if you require all of the template files, they are available for download here. The file includes everything necessary for a functional fluid, as well as a .txt document that details how to create a new one.
