Multiplayer



Multiplayer is a game mode in which Terraria can be played with or against other remote players online. Multiplayer worlds are by default, with  (PvP) available for activation once multiplayer is entered.

Desktop/Console
There are two types of multiplayer environments: Server and "Host & Play".
 * Host & Play games are started via the regular Terraria application. The first player chooses "", chooses options, and starts the world, becoming the host. Other network or internet players can then join, by choosing "" from the multiplayer menu or "" if they are friends on Steam. The world shuts down when the original player leaves the world. This option is normally used for smaller LAN games or for small online games.
 * Servers: Major internet multiplayer games run on servers. Servers are started via the TerrariaServer.exe file included with each Windows Terraria installation, or via a third-party server program – see server for details. A server allows the game world to run on a separate computer, with no graphical requirements, and without requiring any particular player to remain connected. Players can join server games by choosing "" from Terraria's multiplayer menu, then entering the server information. Server lists can be found below, in the "Server lists" section on this page. In server multiplayer games, the host server provides the world file, and has the ability to communicate with players, save the map, close the server, set the time of day, and kick or ban players.


 * The player will need to press "Multiplayer", and then press on their preferred character. Then the screen will read: "Searching for local hosts...", or if the "online" button was pressed then it will just wait until it finds someone. Third-party applications exist to forward these games over the internet rather than just over a single network, such as Multi Terraria or Terraria MP, but others are unsupported and come with no guarantee. There is a maximum of 8 players allowed in one world.
 * To host a LAN World, the device will have to have at least 1GB of RAM.


 * After selecting a character, the player can choose "Multiplayer" and "Start Game" to host a world locally. Players who want to join a world can select "Join World" and select the preferred world from the list. Up to 4 players can join a world at once.
 * Note that Expanded Worlds hosted by New Nintendo 3DS or 2DS systems will prevent users with a Original 3DS or 2DS from joining, as those systems do not support the Expanded World feature.

PvP
Player versus player (PvP) is a multiplayer mode that allows players, or teams of players, to attack each other. PvP is activated by joining a multiplayer world and enabling the PvP option by clicking on the crossed swords near the armor and accessory slots /  in the PvP menu found in the inventory. In the, the only way a player can damage another player is if both players have the PvP option enabled, or through traps such as Boulders, Land Mines or Lava.

There is also the option of joining a team. Teams are represented by the colored icons near the armor and accessory slots. Once a team is selected, there is an on-screen display providing information about the distance (and direction) and health of the teammates. PvP players on the same team can see each other on the minimap, while other PvP players cannot.

If a player has equipped or is holding an informational item such as the, any teammates standing near them can also see the data readout from it.

Capture the Gem
PvP players can play Capture the Gem, which operates similarly to. Capture the Gem requires Large Gems, one for each team, which can be crafted using 15 Amethyst, Topaz, Sapphire, Emerald, Ruby, Amber, or Diamond. Teams attempt to steal the opposing team's gem and bring it back to their own base. Large Gems display as hovering graphics over any player carrying one, and always drop next to killed players, regardless of their character's difficulty setting.

The Large Gems can be held in their respective holders, instead of having a player hold them.

Unique aspects of PvP play

 * The window of invincibility after taking damage is greatly reduced if it came from another player: Normally, the player would receive 2/3 of a second of invincibility (0.67 seconds). In PvP, they only receive 2/15 of a second (0.13 seconds). This can make weapons weaker that have a use time lower than 8.
 * Players killed by other players do not drop coins. By extension, players that are killed by their own explosives also do not drop coins, even in singleplayer worlds.
 * When players respawn, they have full health instead of half health ( 100 health), but this will not work if players were killed by the debuff by another player's weapon.
 * Critical hits and unique knockback values do not apply in PvP. Because of this, the best modifier for weapons that will be exclusively used for PvP and cannot have their speed modified is generally Ruthless, which simply maximizes raw damage per hit.

Multiplayer-exclusive items
These items can only be obtained in multiplayer. However, once the items are obtained, they can be transferred to a singleplayer world.

Although Wormhole Potions only drop from Pots if the game is in multiplayer (even if the player is the only one playing at that time), they can always be crafted, even when playing on singleplayer. However, they are unusable when playing alone, so it could be considered that their usability is multiplayer-exclusive and depends on having other players on the same team.
