Concept enemy stalking AI

[Abb4]

Ive stumbled over some praise for a very specific flavor of horror enemy AI which I would call stalking AI: https://youtu.be/PNGHS6D6CLc

This AI, instead of simply pursuing the player, actively stalks the player from the shadows, indicating its presence through sound effects and visuals (maybe red eyes in the dark).

The implementation could get complicated, but I believe it would add a lot of value to the game.

I have opened a discussion: #55

For advantages and disadvantages, see #55 (comment)

For games that implement that see the discussion as well.

Other games don't go to that extreme, but try to compensate, by adding random background noises, as well as droning music to build up the tension.

I believe the entire concept of the unseen-moving-enemy is an attempt to implement something like this.

All in all this could be a lot of work, so I don't believe we need it for 1.0 but it would be nice to collect some ideas for possible future implementation.

The result of this issue should be a committed design document. I would suggest excalidraw file format, since these diagrams can be serialized and committed to git, including the images embedded within.

Should only be considered as an extension of #10
