Campfire

A campfire is a block that can be used to cook food or act as a light source or smoke signal.

Obtaining
Campfires can be broken with any tool, or without a tool, but axes are the fastest. $$, they cannot be moved or destroyed by pistons, whether lit or unlit. $$, campfires will be broken by pistons.

Campfires can only be reclaimed by mining them using a tool enchanted with Silk Touch. If items are placed on the campfire, the items will always be dropped when it is broken.

Natural generation
Campfires can generate in and  villages.

Trading
Apprentice-level Fisherman villagers have a 50% chance of selling a campfire for 5 emeralds.

Apprentice-level Fisherman villagers have a $2/3$ chance of selling a campfire for 2 emeralds.

Usage
Campfires are lit by default when placed. Campfires can be manually lit by or dispensing flint and steel or fire charges on them, or shooting it with flaming arrow. $$, campfires can also be lit by an item enchanted with fire aspect, or stepping on it while burning. A campfire will become unlit by waterlogging it (placing water in the same block space), or throwing a splash water bottle on it. In $$, they can also be put out by a shovel on it. Campfires will not be extinguished by rain, similarly to Netherrack. Since Dispensers with water Buckets and flint and steel can extinguish and light campfires, respectively, they can be used in redstone creations as memory cells.

Smoke signals
Campfires produce smoke particles that float up around 10 blocks before disappearing. If a hay bale is placed below, the campfire will be a signal fire and the smoke will float up for around 25 blocks instead.

Campfire smoke particles can partially pass through 1.5 blocks above it, the amount of passing particles decreases as the height of the top block increases. When the top block is 1.5 blocks higher than the campfire, its particles are completely blocked.

Campfires that existed prior to Bedrock Edition 1.11.0 (updating world from 1.10.0) will not produce smoke particles.

Damage
Campfires damage mobs standing on top of them even if underwater (with exceptions such as shulkers or guardians), but only if lit, dealing of damage every tick (although damage immunity reduces this to once every half-second). Unlike regular fire, campfires will not cause lasting burning, nor destroy items. Damage taken is considered fire damage and is reduced by armor, shields, the Resistance potion effects, and the Protection and Fire Protection enchantments. Armor will lose item durability, but a shield will not. The player can avoid being damaged at all, either by, using a potion of fire resistance, or by wearing Frost Walker boots, similar to magma blocks. Blocks that are the height of a trapdoor or lower (such as carpets) will not prevent a campfire from damaging mobs and players above it.

Cooking
The player can place raw food (raw beef, raw chicken, raw rabbit, raw porkchop, raw mutton, raw cod, raw salmon, potato, kelp) on a lit campfire by the food item on it. Up to four food items can be placed on a single campfire. On a campfire, foods produce small smoke particles, indicating they are being cooked. Food items take 20 seconds (400 ticks) to cook, compared to 10 seconds for furnaces or 5 seconds for smokers, and will pop off the campfire when finished cooking. Unlike other blocks that can cook food, campfires do not require any kind of fuel and will be able to cook food items indefinitely as long as it remains lit. They also do not have a physical inventory. However, food items cannot be placed on an unlit campfire. Placing a campfire on top of a hopper will cause some of the popped items to be transferred into the hopper, albeit ineffectively - encasing the campfire with the hopper is a good way to efficientize this for a reasonably free way to get cooked food.

Light source
Lit campfires emit a light level of 15. Like most other sources of light, campfires will melt snow up to three blocks around the fire.

Block entity
A campfire has a block entity associated with it that holds additional data about the block.
