The bug
Fire and soul fire are capable of producing minecraft:block particles of themselves in certain situations.
The fact that particles can be produced at all makes no sense, as there are several other blocks in the game for which particles are never produced since particles being produced for them also makes no sense.
Table of results
The following table lists all cases in which minecraft:block particles are generated, and fire and soul fire's behaviour for each of these cases. The expected behaviour for all of these is that no particles are produced.
Event | Result | Notes |
|---|---|---|
Process of breaking | ❌ Particles created | Most easily noticed with swords in Creative |
Being broken | ✔ No particles | Includes /setblock ~ ~ ~ air destroy |
Being sprinted on | ❌ Particles created | Requires sprint-jumping through it and a keen eye |
Being fallen on | ❌ Particles created | Requires falling on a boat inside the fire: |
Being walked on by an iron golem | ❌ Particles created | |
Being dug through by an emerging warden | ❓ Untested | |
Being dug through by a departing warden | ❓ Untested | |
Being dug through by a sniffer | ❓ Untested | |
/particle command | ❌ Particles created | Example: /particle minecraft:block minecraft:fire |
Expected behaviour
As mentioned before, block particles for fire and soul fire should never be created, even if summoned with commands. Currently, only the following four blocks will never show block particles, behaviour which fire and soul fire would be expected to follow:
minecraft:air
minecraft:cave_air
minecraft:void_air
minecraft:moving_piston
Actual behaviour
The game does indeed prevent fire and soul fire block particles from being produced in some cases. However, there do still remain cases where block particles are created, which can be seen in the table.
How to fix
Removing the particle texture definition from the models would not fix this issue, as the game would simply fall back to using the missing texture. As such, fixing this would require code changes. A simple fix would be to just hardcode fire and soul fire to not use particles just like the four aforementioned blocks, but a more data-driven solution may be preferable, removing this hardcoded list from the game.
These approaches are listed in detail in MC-240028.
