Package net.minecraft.server.function

Class FunctionLoader

java.lang.Object
net.minecraft.server.function.FunctionLoader
All Implemented Interfaces:
ResourceReloader
public class FunctionLoader extends Object implements ResourceReloader
The function loader holds the functions and function tags for a CommandFunctionManager to use. In the reloads, it loads the tags in one completable future and each function in a completable future for all functions.

The functions are stored in .mcfunction files; each line is one Minecraft command, with blank lines and contents starting with a trailing hash # sign ignored.

The function tags are ordered, unlike other tags. Each function's order in the collection of functions from the tag is determined by the order it is listed in the JSON files; if it appears multiple times through tag nesting, only its first appearance will be considered.

    • reload

      public CompletableFuture<Void> reload(ResourceReloader.Synchronizer synchronizer, ResourceManager manager, Profiler prepareProfiler, Profiler applyProfiler, Executor prepareExecutor, Executor applyExecutor)
      Performs a reload. Returns a future that is completed when the reload is completed.

      In a reload, there is a prepare stage and an apply stage. For the prepare stage, you should create completable futures with CompletableFuture.supplyAsync(..., prepareExecutor) to ensure the prepare actions are done with the prepare executor. Then, you should have a completable future for all the prepared actions, and call combinedPrepare.thenCompose(synchronizer::waitFor) to notify the synchronizer. Finally, you should run CompletableFuture.thenAcceptAsync(..., applyExecutor) for apply actions. In the end, returns the result of thenAcceptAsync.

      Specified by:
      reload in interface ResourceReloader
      Parameters:
      synchronizer - the synchronizer
      manager - the resource manager
      prepareProfiler - the profiler for prepare stage
      applyProfiler - the profiler for apply stage
      prepareExecutor - the executor for prepare stage
      applyExecutor - the executor for apply stage
      Returns:
      a future for the reload
