Auto Select will automatically select an item to use, depending on where the cursor is pointed. The item does not need to be in the hot bar. By default, Auto Select is activated by pressing Shift on PC, R3 on PS3/PS4, or pressing down the right thumbstick on Xbox 360.
|Blocks and most furniture||Pickaxe|
|Tree, Giant Mushroom, or Cactus||Axe|
|Altar, Shadow Orb or Crimson Heart||Hammer|
|Extractinator||Silt or Slush|
|Bunny Cannon||Explosive Bunny|
|When you point at an empty space or a wall, a light source will be selected based on the following criteria|
|Cursor is far from the player||Glowstick, Spelunker Glowstick or Flare Gun|
|Player and cursor are in water (or other liquid)||Cursed Torch, Ichor Torch, Glowstick or Flare Gun|
|Player in water but cursor is not||Cursed Torch or Ichor Torch|
|If none of the above apply||Any torch|
A Flare Gun without Flares won't be selected. Nor will other light sources such as candles. If more than one item is equally appropriate it will normally select the first one in your inventory. And if the preferred item is unavailable it will usually fall back to something else.
Smart Cursor selects a target based on the active item. By default, it is toggled on and off by pressing Ctrl, or by holding down and dragging the right thumbstick. There is also an option in General Settings to make it last only while the key is held down. Smart Cursor mode is indicated by a slightly wider cursor, and the tile targeted is shown with a yellow box. On the , Smart Cursor is on by default unless the D-Pad or Touch Screen is used to target an area. 版
|Pickaxe||Digs a passage wide enough to pass through in the direction indicated be the cursor. A tunnel going diagonally upwards will often have to be widened to go back down.|
|Axe||Chops the base of the tree nearest the cursor. It will target branches when the base is out of range. An item that functions like an axe/pickaxe will target trees first then blocks. This can be easily seen with the Laser Drill (1.3+).|
|Hammer||Removes the wall nearest the cursor.|
|Block||Places a block at the nearest legal space to the cursor. If the space under the cursor already contains a block or other object, it will do nothing. However if the cursor is over an NPC or player, it will encase them in multiple layers. This is currently the only way to automatically fill a large area with blocks. On the 移動版, this is quite unreliable.|
|Wall||Places a wall at the nearest legal space to the cursor. Unlike other items, walls will only be placed by Smart Cursor within line of sight of the player. This makes it easy to fill a room without the walls "spilling" out.|
|Platform||Adds to existing platforms (in any direction, including vertical).|
|Minecart Track||Extends existing tracks horizontally or diagonally.|
|Wrench||Extends existing wires of the same color.|
|Wire Cutter||Removes the wire nearest the cursor.|
|Acorn||Places an acorn on top of grass if two blocks beside it are free.|
A fresh installation of Terraria 1.3 or later will start with Smart Cursor disabled for placing common blocks. This setting applies to foreground blocks that you would use during construction, such as dirt, wood, and stone. The Smart Cursor will continue to behave as per the 1.2 standard for platforms and walls.
If you wish to use Smart Cursor for common blocks, you will need to edit Terraria's config.json file manually.
Edits to config.json must be performed while the game is not running, or else the new setting will not take effect. You may want to create a backup copy of the config.json file before editing, which will allow you to restore your original configuration later, if needed.
- Browse to your config.json file location (see config.json for common locations).
- Right-click config.json and choose Open With...
- Select Notepad (or your favorite text editor).
- Use the 'Find' option in your text editor and search for this:
- "UseSmartCursorForCommonBlocks": false,
- Edit the line so it now reads:
- "UseSmartCursorForCommonBlocks": true,
- Save your config.json file.
- Launch Terraria.
- Now you will have SmartCursor On
Lock on is a cursor mode that can be used on 電腦版 while playing with a controller, on the , or on the 版 移動版. While holding a weapon, a small yellow triangle appears above the enemy to be targeted. Depending on the chosen setting, Clearest Line or Target Closest, the yellow triangle will appear on the monster closest to the cursor's pointing direction or closest to the player (independently of line of sight). By pressing or tapping the enemy, the enemy will be locked on to, indicated by three triangles rotating around the enemy or by a single yellow triangle above the enemy. From then on, all attacks are automatically directed at that enemy (in the 移動版, all attacks initiated by hold tapping the center of the right thumb stick are directed at the target). Pressing again releases the lock (in the 移動版, the lock is released upon the enemy's defeat or movement offscreen).
This cursor mode can be especially effective while using weapons that require accurate aim, like Yoyos, Ranged Weapons, or Magic Weapons. Lock-on mode makes strafing (dodging while firing) an effortless task.
