No more lag while exploring!\ Load chunks beforehand so you can enjoy exploration.
This DataPack allows you to pregen chunks before you go exploring, so you won't experience lag from generating chunks during exploration.
Very useful for servers where players usually explore simultaneously.
USAGE:
Run `/function help:chunk_pregenerator` to get all info needed to use this DataPack.\ There are 3 parameters you should know:
- Cx: x coordinate of the square's center
- Cy: y coordinate of the square's center
- R: square's radius in chunks (each chunk is 16 blocks long)
Here is an example:
Each '✅' is a chunk that will be loaded.\ Each '❌' is a chunk that won't be loaded.\ Running `/function c_pre:start {Cx: 0, Cz: 0, R: 3}`.\ ❌❌❌❌❌❌❌❌❌\ ❌✅✅✅✅✅✅✅❌\ ❌✅✅✅✅✅✅✅❌\ ❌✅✅✅✅✅✅✅❌\ ❌✅✅✅🟢✅✅✅❌\ ❌✅✅✅✅✅✅✅❌\ ❌✅✅✅✅✅✅✅❌\ ❌✅✅✅✅✅✅✅❌\ ❌❌❌❌❌❌❌❌❌\
SETTINGS:
You can change the maximum radius with the command below.\ `/function c_pre:settings/set_max_radius {R:250}`\ Change _"250"_ to any number you want.
⚠️ NOTE: The more chunks you pregen, the more lag and time it will take.
