Fluid tags

Fluids can have RebarFluidTags associated with them which can store arbitrary data. For example: - The temperature of the fluid (Rebar has this tag by default) - The energy density of the fluid (e.g. diesel could have a higher energy density than plant oil) - Whether the liquid can be used as a coolant

Creating a new tag

To create a new tag, simply create a new class to represent your tag, and implement the RebarFluidTag class. This class has only one method; getDisplayText. This method is used to display your tag in the fluid's lore.

You can then add the tag to your fluid using RebarFluid#addTag.

You can use RebarFluid#hasTag to check if a fluid has a specific tag, and RebarFluid#getTag to get a given tag from a fluid.

Warning

A common point of confusion is that fluid tags are associated with a single fluid type. You cannot use the tag system to (for example) assign a numeric temperature to a fluid which allows water to be heated up in a boiler. This is because tags are assigned to a fluid type, not to a fluid that exists in the world. This is primarily due to hugely increased complexity and reduced performance during fluid routing.
