PeakAMap

Find out what biomes are currently in rotation and select a map to play with an in-game UI.

PeakAMap searches through each map to find out what biomes they have and lets players pick from them. There shouldn't be, but there may be inaccuracies. For performance reasons, the loading and searching is done beforehand and saved in a file included with PeakAMap. If this file is missing or a new maps are patched in, then PeakAMap will automatically create this file when the game starts. For slower PCs, this process may take 2-4 minutes.

Features

• Use a UI to Select a Map to Play

  • Biomes of each map are displayed.
  • Choose to play a custom map or to play the daily map.
  

• Biomes are Displayed in the HUD During Your Run

  

  TIP: This feature is optional. If you don't like having extra text on your screen, this feature can be disabled in your .cfg file. Instructions on how to do so is further below in the "Configuration" section.

• Map Rotation Info is Preloaded for the Suppported PEAK Version

  • Currently supporting map rotation from PEAK 1.60.c

• Support for Future Map Patches

  • PeakAMap SHOULD still display correct information when PEAK patches in new maps.
  • If PeakAMap doesn't have data for the current map rotation or there are issues with the file containing this data, the map rotation info will be loaded, searched, and saved at the game's start

    TIP: This feature is optional. If you're only interested in selecting a map without the biome info or if preloading takes too long. This feature can be disabled in your .cfg file. Instructions on how to do so is further below in the "Configuration" section.

• Partial Language Support

  • Some phrases/words that were already supported in game will be supported in PeakAMap.

• Biome Variant and Open Tomb Info

  • Extra information on current maps are stored in the .\BepInEx\plugins\PeakAMap\data\ folder in map_rotation-<version>.json. (Note: The <version> refers to the PEAK game version, not PeakAMap mod version).

    NOTE: Only available inside of file. Not shown in game. Currently, you can only view the biome variant and open tomb information in the PeakAMap's data file. There are plans to add a way to display these in game, but it is not supported at the moment.

    CAUTION: DO NOT modify these files. Doing so may cause inaccurate biome information to display in the PeakAMap UI or preloading to start due to failure to read the file.
