An UE4 plugin written entirely in C++ which adds support for a simple Camera Lock On / Targeting system. It was first developed and tested in Blueprints, and then converted and rewritten into a C++ module and plugin.

Features:

• Customizable with a set of options that can be overridden in Blueprints.
• Easy setup: only one Actor component to attach and a minimum of one functions to bind to input.
• Target closest enemy (Pawns by default, customizable with TargetableActors UPROPERTY).
• Break on Line of Sight when getting behind an object.
• Break Target when getting outside minimum distance to enable.
• Simple TargetLockedOn Widget included, can be customized / overridden.
• Option to control character rotation when locked on.
• Switch to new target with axis input (on mouse / gamepad axis movement).
• Two Blueprint implementable events on component on Target Locked On and Off.
• 100% open source for anyone to compile from the source code repository

Added in 1.3.0 (for Engine version 5.1)

• Update example map to use Enhanced Input bindings

Added in 1.27.0 (for Engine version 4.26 / 4.27 / 5.0)

• Added support for Local multiplayer Split Screen

Added in 1.26.0 (for Engine version 4.26)

Several small quality of life updates and minor tweaks (thanks to @josator)

• Flag to allow Pitch input while targeting (look up/down).
• Collision channel as UPROPERTY configurable in editor
• StartRotating set to < 1.0 to allow usage with controller sticks
• UFUNCTION to detect target system status on blueprint

Misc:

• Added Test Map within Plugins Content folder.
• Lowered PitchDistanceOffset value to have a slightly better view at close range by default
• Set ShouldControlRotation to false by default
