The Basics
A simple lock on system that displays an icon on 'lock on-able' targets and changes when you have locked on.
​
When you lock on, the camera changes and you strafe around the target until you unlock or move far enough away.
Features
- Automatic camera and movement change when locked on.
- Lock on event can be bound or called.
- Switchable textures for locked on and available to lock on.
- Add a tag to any object 'lockon' which will then be recognized as a lock on-able target.
