Water is a fluid that naturally generates quite abundantly in the Overworld. It has the ability to flow freely in any direction up to four blocks from its source block, but it can flow infinitely in the downward direction. Water is very helpful for players as it can be used for farming, negating fall damage, making generators, etc.
Water doesn't exist as item blocks, it can only be collected by using a bucket on a water source block. Water naturally generates in the Overworld in oceans, rivers, lakes, springs, villages, strongholds, ocean monuments, ancient cities, and desert wells. Water will never generate in the Nether and will instantly evaporate if placed there with a bucket. Water spends most of its time stationary, rather than flowing – regardless of its level, or whether it contains a current downward flow or to the side. When specifically triggered by a block update, water changes to 'flowing', updates its level, then changes back to stationery. Water springs are generated as flowing, and oceans and rivers are generated as stationary.
Water spreads horizontally and downward into nearby air blocks. Water can spread downward infinitely until stopped by a block, and 7 blocks horizontally from a source block on a flat surface. Water spreads at a rate of 1 block every 5 game ticks, or 4 blocks per second. Spreading water extinguishes fire and washes away certain types of items or placed blocks, causing them to drop as items and then carrying them along in the flow until the edge of the spread.
Water is a fluid that can be used by players for a large number of things. This includes things such as transportation, farming, generators, etc. Water of any depth prevents any entity, including the player, from sustaining falling damage if they fall into it, regardless of the distance fallen.
Players can swim in water bodies, both on the surface and under as well. The crouch button can be used to go underwater here as the jump button allows the player to rise up to the surface. The sprint button can be used to put the player in "swim mode" only when the player is completely submerged in water. When in swim mode, the player is horizontal and one block high.
Water can be used for transporting players, mobs, and items. For mobs and players, boats can be used for transportation over water bodies such as lakes and oceans. Water can also be used for transporting things vertically. By placing a block of soul sand or magma below water, a column of bubbles are created which can either push the entity up or pull it down respectively.
Water is an essential part of farming any sort of crop or food item. When a grass/dirt block is turned into a farmland block, it spawns in a dry state, meaning that crops planted on it will not grow to completion as the dry farmland block will turn into a dirt block if not supplied with water. Once a farmland block is within 7 blocks range of a water source block, it will be in the wet state, allowing players to grow crops on them. For crops such as wheat, sugarcane, pumpkins, and melons, water must be present.
Water is also used to farm stone or obsidian depending on what you need. This works due to the interaction water has with lava and the way they come into contact. When lava is allowed to flow into water, cobblestone is generated, whereas obsidian is generated when water flows into lava. When either piece of cobblestone or obsidian is removed, another one will take its place, this allows the player to farm cobblestone and obsidian.
Some mobs can be drowned in water, this can be used to make traps or experience farms. A water trap is not effective against zombie pigmen; however, it is very effective against creepers. Water can push creepers away from buildings or land that aren’t to be destroyed; after all, explosions do not destroy blocks in water. Certain mobs show an odd fondness towards the water, these mobs being the general peaceful mobs, such as pigs and chickens.
Water is one of the most useful things in the game. You can find water quite easily and picking it up is also quite easy and straightforward. Water can be found in oceans, lakes, rivers, and even in caverns underground.
A. To make an infinite water source you will need to dig a 2x2 square and place two buckets of water in the diagonally opposite corners.
