It is raining and the player is at or above the surface. The vertical location must be above roughly the midpoint / start of the Underground layer The lateral location must be within 338 tiles (676 feet) from either edge of the map. Underworld, Cavern, Underground, Surface, SpaceĬhecked in that order the player is within said layer. Each Sunflower present subtracts 1 from the game's count of tombstones, effectively negating it. The biomes are checked for in that order.Īt least 4 Tombstones for basic biome, 7 Tombstones for all features. Within the code, being within the radius of a Water Candle or Peace Candle is treated as being in a biome. Unlike the Corruption and Hallow, the small plants that grow in the Crimson do not contribute towards its tile count requirement.Įach Corruption or Crimson block which is also within range subtracts 1 from the game's count of Hallow blocks.Vile Mushrooms or other Wild Corruption Plants.Įach Sunflower subtracts 80 / 40 / 5 from the game's count of Corruption blocks, and each Hallow block subtracts 1.Įach Sunflower subtracts 80 / 40 / 5 from the game's count of Crimson blocks, and each Hallow block subtracts 1.Must be standing in front of a wall with an ID between 48 and 53, inclusive, which corresponds to the unsafe Amethyst, Topaz, Sapphire, Emerald, Ruby, and Diamond walls.Īt least 300 / 200 blocks of the following: Must be standing in front of a natural or unnatural Hive wall. Must be standing in front of a natural or unnatural Marble wall. Must be standing in front of a natural or unnatural Granite wall. Must be in a Desert biome and standing in front of a natural Sandstone or Hardened Sandstone wall. Worthy of note is that many areas not conventionally considered as biomes are treated as such in the code.Īt least 250 Dungeon Bricks(regular or cracked) and a naturally-placed wall other than Dirt Wall (on PC, Console, Mobile, and tModLoader, this must be a naturally-placed Dungeon Brick Wall) below −4 feet. Biomes are set in the order listed below. The area used for counting required blocks for the existence of biomes at a location appears to be 85 / 50 tiles to each side and approximately 61 / 42 below and 64 / 44 above, from the location of the player. This can lead to, for example in an Underworld Crimson, Underworld and Crimson enemies both spawning in the applicable areas. Player action can similarly introduce Corruption, Crimson, Hallow, Desert, Jungle, Mushroom, Meteorite, or Snow biomes to any location from Underworld to Space. Floating Islands can be Corrupted/Crimsoned or Hallowed upon entry of Hardmode, and such high-layered biomes are even required by some Angler quests. The simplest examples are Hallowed, Crimson, and Corrupted Deserts however, not only Deserts can be hybridized. Hybrid biomes are those created by the requirements being met for multiple biomes in a certain area. 5.6 Corrupted, Crimson, and Hallowed IceĪlthough many basic biomes appear at the world generation or are triggered by events, hybrid biomes may be synthesized by world mechanics or through player action.5.5 Corrupted, Crimson, and Hallowed Desert.In pre-Hardmode, the evil biomes will only overtake other biomes via grass, ice, sand, and stone, but once Hardmode begins all three biomes can spread directly through most soil blocks, vines, and thorny bushes. The Corruption, Crimson, and Hallow are all 'contagious' biomes which spread to certain adjacent blocks. The world's evil biome roots deeper with the Underground Corruption/ Crimson, and the Hallow and Underground Hallow form as well. Once Hardmode is activated, a few new biomes form.

The Glowing Mushroom biome also appears in the Cavern layer, and the Underworld spans the entire bottom of the world. These include the Underground Desert, Ice biome, and Underground Jungle. Going any deeper, the player will find unique subterranean variants of most of these. These Surface biomes extend into the Underground layer. Biomes on the Surface layer include Forests, Deserts, the Snow biome, the Jungle, the Dungeon, the evil biome (either the Corruption or the Crimson), and at the far ends of the world, the two Oceans. Spanning the world's ceiling is the Space biome. Every biome has its own characteristic terrain blocks, collectible items, backdrops, enemies, critters, theme music, background walls, Angler quest fish, and other features. Biomes are the different types of areas that any Terraria world can contain.
