I am an artist and I have already designed pawns for a new animal type with simple predator AI similar to the dark young from Cosmic Horrors. I would like to create statues that are only allowed to move when the player is looking away from them, but the animal freezes in place like a statue if a pawn is looking at it.
I am new to programming and still not so good at it... so I am exploring mods that already exist with similar features. I was reading the code for Real Fog of War on Github and it seems like it might already have the framework for this concept.

Specifically;
using RimWorldRealFoW.Utils;
and
handleSeenAndCache, mapCompSeenFog, faction, factionShownCells,

Jecrell's Rim of Madness vampires, dark young and star vampires already have a feature that causes a negative moodlet when seen by pawns, however I do not know for certain if this is a radial effect or if it occurs in a cone as line of sight. Do you think its possible for me to write some simple process for the statue movement freezing effect to occur, and would it make sense to use RimWorldRealFoW.Utils; in order to make sure the effect is based on line of sight instead of radial proximity?

Thanks for any insight on this issue and thank you for maintaining this wonderful mod, its lots of fun!
