Async Locator Refined
Changes the searching of features to be asynchronous to mitigate associated lag. Maintained version
About this Mod
This mod is a port of the original version.
I have obtained the creator’s permission to port it.
For versions 1.20.1 or earlier, download the original mod here
Modifies vanilla behaviour when locating features to run asynchronously, mitigating associated lag.
This is currently implemented for:
- Locate structure command when executed by a user
- Locate biome command when executed by a user (v1.5.0+)
- Villager explorer map trade offers
- Dolphin treasure finding
- Exploration map in chests
This mod is only required to be installed server side! So clients only need this installed if they want it for single player.
This alone only works for vanilla (see list above). Other
mods may need to implement usage of this mod themselves to make use of
the async functionality.
Incompatibilities
Mods that affect vanilla's structure locating features may impact Async Locator's functionality.
Right now, the list below states other mods that I'm aware of:
Has been seen that on startup only one of either Async Locator's or
Structure Essentials' locating improvements will work. No real issues
otherwise, but only one of the mods are required.
Mod Integration
Other mods can also use Async Locators as a dependency to implement the asynchronous locating into their own code.
To do so, please use CurseMaven or Modrinth Maven to add this mod to your build.gradle, and then make use of the AsyncLocator class and/or logic classes.
