I am attempting to make a fluid for my mod in 1.16.4, but I cannot find any help online for how this is done. I have tried looking at how other mods do it and so far I have a Fluid class, a Fluid Block class, and a Bucket class. So far my fluid seems to exist in some capacity, but the bucket doesn't work, and when I try setblock, it does not work with the fluid block, but it does work with the still version of the fluid, except the fluid state still shows as empty, it just now has the falling boolean property. At this point I am pretty much stuck. I assume I am missing something (probably obvious), but I can't figure out what it is.
Fluid class:
