What is this?
  • This mod adds a number of persistent wandering Reaper Leviathans.
  • They are persistent in the sense that, once they are de-spawned within the game, the mod simulates their movement on the world map.
  • Once the player gets close enough to a simulated persistent reaper, the mod will spawn the reaper into its simulated position.
  • The locations of the persistent reapers can be visualized by using the "Print Reaper Map to File" button.

Why might I want this?

  • If you want to add more terror into your gameplay experience
  • If you want to make the game more unpredictable
  • If you think Reaper Leviathans should exist everywhere (except beyond the crater edge)
  • If you just like Reaper Leviathans!

Options:
  • Toggle Persistent Reapers: enable or disable the persistent reapers
  • Number of Persistent Reapers: change the number of persistent reapers across the whole map. See ReaperNumber
  • Persistent Reaper Behavior: see Behavior
  • Scent Lifetime (seconds): see Human-Hunter
  • Depth Map: optionally disallow reapers from entering shallow areas
  • Reaper Update Interval (seconds): Optionally make reapers update less frequently, to save on performance.
  • Print Reaper Map to File: print an ascii map of persistent reaper locations to a file in the mod directory

ReaperNumber:
  • The default value is 50 persistent reapers. This makes for 1 reaper per area about the size of a mushroom forest.
  • You can print the reaper map to visualize a reaper density that's good for you.

Behavior:
  • Normal: unchanged from vanilla
  • Bloodthirsty: Reapers are hungrier and more aggressive
  • HumanHunter: see Human-Hunter

Human-Hunter:
  • The player leaves behind a trail anywhere they go. The trail expires [Scent Lifetime] seconds after being drawn. If a persistent reaper (simulated or not) happens to find the trail, they will follow it until the trail runs cold.
  • If a persistent reaper sees or hears the player, it will lock onto the player. Once locked on, a persistent reaper will not easily be shaken.
  • These reapers are only interested in the player, and will not target any other creature.

The Depth Map:
  • The Depth Map is used to define legal placements for the persistent reapers.
  • In general it keeps them out of the void, and optionally out of the shallows.
  • The included depth maps can be visualized in the blue images on this web page.
  • You can generate a custom map using the Companion Mod: Depth Scanner.

Future Work:
  • Improve the readability of the Reaper Map
  • Alternate Persistent Reaper skins/colors (please contact me if you do this kind of thing)
  • Let PR data-per-save-file persist through save/load
