Smooth Flint
by Neni-o
Smooth Flint changes how Flint and Steel ignites things, with clearer ignite rules for blocks, living mobs, items and a few non-living entities.
What it does
Smooth Flint is a small overhaul of the vanilla Flint and Steel item. It sets clearer ignite rules and adds a few extra cases, while keeping the item close to how it behaves in vanilla. Living mobs in water do not catch fire, which prevents underwater use of the item as a trick, and item entities cannot be ignited. Dragon fireballs are excluded as well, and creepers keep their vanilla behavior, though Flint and Steel triggers a special mechanic on them.
Mob mechanics are controlled through a simple config file, so a server owner can decide how the rules apply on a given server. Ignition can reach nearby living entities, and non-living entities such as boats and wind charges can be set on fire. The mod is server required and client optional: the server needs it, and players may add it or leave it out. It is published for Fabric and NeoForge on 12 game versions, 1.21 – 1.21.11, and is released under the MIT License. It is not open source.
Key features
Sensible ignite rules
Flint and Steel follows clearer rules for which blocks and entities it can set on fire.
Configurable entity ignition
Using the item on an entity can ignite it, and the behavior can be changed in the config file.
Nearby living entities
Ignition can also reach living entities close to the target, not only the one that was clicked.
Vanilla safety cases
Item entities, dragon fireballs and water-submerged mobs are handled as special cases so the item stays safe to use.
Non-living targets
Boats and wind charges can be set on fire, which extends the item beyond living mobs.
