This article is about world creation and structure. For world size measurements and advantages, see Map size.

The term world refers to Terraria's virtual world system which all of the gameplay takes place in. The world holds the entirety of the game content, such as items, enemies, objects, and so on. Terraria worlds are 2D and navigated in a platform game-like manner. World appearance is subject to some settings.

The term map is partly synonymous with world but also refers to the minimap, the in-game map system (not to be confused with the big map that takes up the whole screen).

Creation and access[edit | edit source]

Worlds are created in the game's main menu through the Single Player option. After selecting a character, the player is provided the options of selecting (for playing) already created worlds if they have made any, creating new worlds, favoriting worlds, integrating worlds with their Steam Cloud in order to easily access them on different computers, and deleting them.

World creation presents the player with these options (see images on the right). Options slightly differ between game platforms.

  • Enter World Name: ____
  • Desktop Version Enter Seed:
  • World Size:
    • Desktop versionConsole versionOld-gen console versionMobile version Small, Medium, Large
    • 3DS version Normal, Expanded (Similar to Small worlds on other versions)
  • Desktop, Console, and Mobile Versions Difficulty:
    • Desktop Version Journey - With great power comes great responsibility (Unearth your creativity)
    • Desktop Version Classic / Console VersionMobile Version Normal - Your Adventure Begins... (The Standard Terraria Experience)
    • Expert - Fortune & Glory, Kid. (Far Greater Difficulty & Loot)
    • Desktop Version Master - Game over man, game over! (Brutally hard, for the truly brave)
  • Desktop VersionConsole Version World evil: (Console Version only available once a player reaches Hardmode on any world or loads a Hardmode world)

Beyond this the creation is an automated process which generates a random world (if world seed is not used). This seeks to ensure that no two worlds are identical, allowing each new world to be a somewhat new experience. The perhaps largest difference between worlds is some of them having the Corruption whereas others have the Crimson. Each of these evil biomes offer a player unique materials, enemies and drops.

Only one world can be accessed at a given time (in similar fashion to how the player may only control one character at a time), but the player is free to create as many worlds as they can store on their device or computer. Characters are not locked to worlds (with the exception that journey mode characters can only enter worlds on journey difficulty), so it is, for example, possible for an end-game character to play in worlds that have not made that much progression, or to bring resources from one world to another.

Since the contents of a character's inventory, Piggy Bank, Safe, Defender's ForgeDesktop VersionConsole Version and Void Vault are stored with the character, the character has access to these no matter which world they visit.

A given world can be used both for single-player and multiplayer. In case of the latter the world is used to make a server (see Guide:Setting up a server).

When entering a new world, the character will appear at the World Spawn Point, usually on the surface close to the horizontal mid-point of the map. A character's individual spawn point can be altered using a bed. If the player dies, or teleports using a Recall Potion, Magic Mirror/Ice MirrorDesktop, Console, and Mobile Versions, or Cell PhoneDesktop, Console, and Mobile Versions, they will return to their spawn point.

World exit is typically done through the settings option that appears when the inventory is opened (see game controls), though this depends on game platform.

Structure and content[edit | edit source]

Worlds are structured into layers and biomes in order to provide various content depending on the player's location. World content is also provided through a range of time-based events like invasions, nighttime, boss battles, etc. The world states of pre-Hardmode or Hardmode also determine what content is available. The world's biomes and layers, time-based events, and Hardmode are designed to gradually become accessible as the player becomes more skilled and the character stronger. This progression gameplay can pose a unique challenge in multiplayer, as one player could progress more quickly than the others, only to find themselves with a weak team during difficult battles.

World content is also dependent on game platform. Old-gen console version Old-gen console and 3DS version3DS have exclusive content not found on other platforms, and vice-versa.

Notes[edit | edit source]

  • Worlds can be viewed and sometimes edited by third-party programs known as map viewers.
  • Worlds, like characters, are stored as individual files. A world has the file extension .wld. On the Windows platform, they can be found in the "%USERPROFILE%\Documents\My Games\Terraria\Worlds" directory.
    • Windows Steam users who have their worlds moved to the Steam Cloud will find them under "C:\Program Files (x86)\Steam\userdata\<userID>\105600\remote\worlds" by default. See this article for world locations in the Mac and Linux versions of the game.
  • The leaves of the Tree icon when selecting a world will change depending on the status of the world. The left half will always represent the world's naturally spawned evil biome, while the right will be a pure Forest tree. In some secret world seeds, both evil biomes will be native to the world, resulting in a tree that is both corrupt and crimson with no pure representation. In Hardmode, the bottom right quarter and half of the left branch will turn yellow, representing The Hallow.
