Lock on

Lock on or Target Lock is a mechanic which allows players to automatically target enemies, bosses, and critters.
Behavior
Right: The enemy is now locked on.
Lock on is enabled at all times on the Console version, Mobile version, and Nintendo version. On the Desktop version, it is automatically enabled when using a suitable controller.
Locking onto targets
- The player can use any button assigned to "Lock On" / "Lock target" in the settings (
/ 
/ 
by default) to lock onto targets. The button can be pressed again to stop targeting or switch targets. - The Lock On button (
) can be pressed to lock onto targets, and can be pressed again to stop targeting or switch targets.
While an NPC is being targeted, three yellow arrows will surround it, and from then on, all of the player's attacks will be directed towards it. If the targeted NPC goes off-screen, two arrows will point towards it.
The "Lock On Priority" setting can be used to change how potential targets are sorted. Clearest Line will target the NPC closest to the cursor, based on line of sight from the player. Target Closest will target the NPC closest to the player, regardless of any intervening tiles.
Notes
- Enemy caster spells can be targeted.
- Invincible enemies, NPCs, and Players cannot be targeted.
- Lock on often will deactivate when an enemy becomes invincible or loses its hitbox for a period of time, such as when certain enemies teleport.
Tips
- Lock on is a useful compensation for the small screen size on the Mobile version and Nintendo version.
- It can be especially helpful when using weapons that require accurate aim, like Yoyos, Ranged weapons, or Magic weapons, making strafing (dodging while firing) an effortless task.
- In the Expert Mode Brain of Cthulhu fight, auto-aim will always go for the true brain in the second phase.
- Lock on only fires at the position the enemy is at when a weapon is used, making it disadvantageous to use against faster or smaller enemies, as well as weapon with slow projectiles as all shots may miss.
- Although functional in the Mobile version's 1.2 update (and all updates subsequently), and despite occasionally showing the lock-on indicator in said version, the Lock on feature is unusable before the Mobile version 1.3.0.7 update.
