Usage
Reading
Caves Compendiums provides insightful documentation about the general content Alex's Caves has to offer, such as information on the biomes, mobs, and progression this mod adds. To use this book, holding and using it will cause it to open on your screen. From there, simply hovering your cursor over or past the side of a page will cause it to play a swaying animation if there is another page before or after it. This animation indicates that the page is ready to flip over to the previous/next page by pressing any mouse button.
Unlocking information
- Main article: Cave Codex § Compendium unlocking
In the Cave Compendium, there are 4 sections about each biome this mod adds. However, these sections first need to be unlocked with the use of their corresponding type of cave codex. Luckily, flipping to the next few pages will tell you how to obtain a cave codex and how to get started finding these rare cave biomes.
Sections and chapters
If a unique type of cave codex has been used for the first time, the matching section and Introduction chapter of the codex will be unlocked in the Cave Compendium.
From there is where you can unlock 3 more chapters in the same section with the use of 3 extra cave codices of the same type. The extra chapters you can unlock are labelled and write about the Resources, Inhabitants, and Utilities each biome has to offer.
Secrets
- Main article: Cave Codex § Secret unlocking
If the used Cave Codex pertains to the Primordial Caves or Toxic Caves, one extra codex can be used to unlock further information in previously unlocked chapters about their corresponding biome.
