Sponge “What be That?” List


This documentation refers to an outdated SpongeAPI version and is no longer actively maintained. While the code examples still work for that API version, the policies, guidelines, and some links may have changed. Please refer to the latest version of the documentation for those.

This be to explain many o’ them weird words, parables and cuss-words what ye find in these parts. Some be anchored to another shore with more tales fer yer edification. We’ll not be teaching of Java nor the SpongeAPI here, go fishin’.


All these tales be talking aboot Minecraft, or Sponge, or both, ye scurvy dog.
