About this project
What does Useful Structures add?
FEATURES
Adds 12 fallen birch and oak log types of length 4-6 in the minecraft:forest biome with iron or stone axes that can be obtained by left- or right-clicking, along with many other ways to obtain them.
Adds 6 Healing Fire variants (with random rotations), generating in the minecraft:taiga biome. The only difference between variants is the different amounts and locations of logs. Each fire will heal you by 1 HP (0.5 Hearts) every 3 seconds. Breaking the campfire will permanently remove its effect. The coarse dirt around the fire will not allow tree generation.
Adds the Desert Arena, generating in the minecraft:desert biome. It contains a barrel of loot, and even more if you're willing to uncover the loot hidden in the sand, but beware the monsters that arrive at night.
FUTURE PLANS
Rock and ore piles with pickaxes, along with other features, may be added in the future.
VERSIONS
Supports 1.21.5 - 26.3
COMPATIBILITY/BUGS
As long as there are no packs with the same filenames, you should be fine.
If there are any bugs, including floating "ghost" tools (survival causes should be fixed but may break with /kill-ing certain entities), please report them (with steps to reproduce them) here.
Uses repeating tick functions, I tried to make them optimized but may affect performance.
