Blocks

Blocks are the primary components of every Terraria world. They make up nearly all of the game's terrain, with the preponderance of a particular block type in an area determining its biome. Nearly all blocks are collectible for use by players, and are mined with a Pickaxe, Drill, or an explosive. All block types can be stacked up to 9999 in a single inventory slot.
* The most common blocks from world generation are Dirt and Stone.
* Most blocks can be crafted into walls and vice-versa. Nearly all block types have a corresponding wall type.
* Most blocks are foreground objects, and can be used to impede or block player and enemy movement. Background blocks include Inactive Stone Block, Living Fire Block, Bubble, and Smoke Block.
* Most blocks can be shaped into half-blocks and angled slopes using a Hammer.
There are currently 192 block types, including natural, crafted, purchased, and summoned block types.
== Naturally Occurring Blocks ==
These blocks are created when the world is generated. Though few of them are renewable, more can always be found by generating new worlds.
=== Soils ===
Soils are the most accessible type of block in the game, and they make up the majority of the world. Many of them grow Plants naturally. All soils can be mined with a Copper Pickaxe or Tin Pickaxe (except for the Stone variants as noted below). Soils are the only blocks that can be converted by the Corruption, Crimson, and Hallow. All soils are destroyed by explosives.
=== Grown Blocks ===
These blocks drop when their respective plant is looted from the environment using the necessary tool. Once in the player's inventory, they can be placed like other blocks and likewise looted with a Pickaxe, Drill, or explosives.
=== Other Found Blocks ===
These blocks are found in various parts of the world.
=== Trap Blocks ===
Trap blocks are likewise found throughout the world. Unlike other blocks they feature special abilities which can be activated by a trigger through Wire. All trap blocks can be destroyed by explosives. As of 1.3.1, their direction of fire can be changed with any Hammer.
=== Ore Blocks ===
Ores are found underground (With the exception of Luminite and Meteorite), some types only in certain biomes. They are used in the crafting of Bars, which in turn are used to craft Weapons, Armor, Furniture, and more. Many are used to make Bricks or other blocks.
=== Gem Blocks ===
Gems are valuable materials that can be found in veins underground. They can be found in two forms; as gem blocks embedded in Stone Blocks or on the sides of Stone Blocks, or as background objects placed onto Stone Blocks. Mining either version will provide the respective gem type. Gem blocks can be created by the player in the .
Amber is also a gem, but can only be obtained from Silt, Slush or . In the , it can also be found on blocks in the Underground Desert.
== Bricks ==
Bricks are a specific type of crafted block with a repeating rectangular pattern. Though many bricks are crafted from ores and soils, some can only be looted from the environment (or in one case, enemies). All Bricks have the word 'Brick' in their name (however, Mudstone Brick is called Mudstone Block on ).
Bricks have no sell value. Most crafted bricks are made using a Furnace, Hellforge and/or Titanium/Adamantite Forge. 
== Crafted Blocks ==
These blocks are obtained through crafting at a crafting station.
== Other Blocks ==
=== Purchased Blocks ===
These blocks are bought from NPCs.
=== Looted Blocks ===
These blocks are obtained in various ways, mostly as drops from enemies.
=== Summoned Blocks ===
== Notes ==
* Blocks directly below a Tree, Cactus, Chest, or Altar cannot be mined until the item sitting above is first removed.
** However, blocks beneath Chests and Altars can be swapped with other blocks.
* Blocks growing Grass or Moss cannot be mined before their vegetation is destroyed, which is generally done with a single extra hit.
* If the player ends up overlapped with a block, they will behave as if the overlapped blocks are not there.
** An exception to this is if the player is overlapped with a sloped block. In these circumstances, the player will usually be ejected depending on the orientation of the block. This can be utilized as a method of transportation, known as a Hoik.
