This sight system is a highly optimized (like, REALLY optimized) sight system for any kind of NPC

I was annoyed that all NPC systems use raycasting just for the torso or the head despite needing accuracy, so I made this system that detects any kind of limb and the location inside of the limb.

Despite raycasts happening 60 times a second (maximum, not frame dependant), this system uses a modified version of FastCast to handle it's raycasts in a few hacky ways.

This AI system was done as I was very tired of making a new AI from the ground up anytime I wanted to make a roaming AI monster for a horror game.

The system contains 1,356 lines of highly optimized code (for reference, before optimization, the system was nearly 2600 lines of code.)

Fun Fact: Any AI that properly uses this system does NOT have collision on anything other than walls, rather it avoids objects at all costs , meaning it won't get stuck, but it also won't attempt to go through walls or objects.

This is an unfinished movement system and camera system for my game, Sane.

ALL of the movement and camera is done fully custom by reverse engineering Unreal Engine's default first person camera and movement is done without any prior help

Movement and camera work also supports Controller and mobile, albeit cursed, it works and is fully playable.
