-====== Activities ======
-This is summary of how to add stuff for villagers to do. [[https://github.com/EmmanuelMess/ReligiousVillagersMinecraftMod|Here]] is the repo with the full code. The accessors are not explained here, they are at [[tutorial:mixin_accessors|Mixin Accessors]].
-An activity is a set of tasks.
-First register the activity:
-<code java [enable_line_numbers="true"]>
-    public static final Activity PRAY = Activity.register("pray");
-</code>
-Then create a task:
-<code java [enable_line_numbers="true"]>
-public class FindTempleTask extends Task<VillagerEntity> {
-    public FindTempleTask() {
-        super(ImmutableMap.of(ReligiousVillagersMod.MOSQUE_POINT, MemoryModuleState.VALUE_ABSENT));//Conditions to be met to start the task
-    }
-    protected boolean shouldRun(ServerWorld world, VillagerEntity entity) {
-        return world.getPointOfInterestStorage()
-                .getNearestPosition(
-                        ReligiousVillagersMod.BELIEVER.getCompletionCondition(),
-                        entity.getBlockPos(),
-,
-                        PointOfInterestStorage.OccupationStatus.ANY
-                ).isPresent();
-    }
-    protected void run(ServerWorld world, VillagerEntity entity, long time) {
-        ReligiousVillagersMod.LOGGER.info("FindTemple:run!");
-        world.getPointOfInterestStorage()
-                .getPositions(
-                        ReligiousVillagersMod.BELIEVER.getCompletionCondition(),
-                        (blockPos) -> {
-                            Path path = entity
-                                    .getNavigation()
-                                    .findPathTo(blockPos, ReligiousVillagersMod.BELIEVER.getSearchDistance());
-                            return (path != null && path.reachesTarget());
-                        },
-                        entity.getBlockPos(),
-,
-                        PointOfInterestStorage.OccupationStatus.ANY
-                )
-                .findAny()
-                .ifPresent(blockPos -> {
-                    GlobalPos globalPos = GlobalPos.create(world.getRegistryKey(), blockPos);
-                    entity.getBrain().remember(ReligiousVillagersMod.MOSQUE_POINT, globalPos);
-                });
-    }
-}
-</code>
-This task just finds a ReligiousVillagersMod.MOSQUE_POINT:
-<code java [enable_line_numbers="true"]>
-	public static final MemoryModuleType<GlobalPos> MOSQUE_POINT = MemoryModuleType.register(
-			"mosque_point",
-			GlobalPos.CODEC
-	);
-</code>
-The mosque point is a point of interest (like work benches, or a home):
-<code java [enable_line_numbers="true"]>
-        static {
-	       public static final PointOfInterestType BELIEVER = PointOfInterestType.register(
-                                "believer", PointOfInterestType.getAllStatesOf(Blocks.EMERALD_BLOCK), 32, 100
-	       );
-               addPointsOfInterest();
-        }
-        private static void addPointsOfInterest() {
-		VillagerEntityAccessor.setPointsOfInterest(
-				new ImmutableMap.Builder<MemoryModuleType<GlobalPos>, BiPredicate<VillagerEntity, PointOfInterestType>>()
-						.putAll(VillagerEntity.POINTS_OF_INTEREST)
-						.put(MOSQUE_POINT, (villagerEntity, pointOfInterestType) -> pointOfInterestType == BELIEVER)
-						.build());
-	}
-</code>
-The position is saved in a memory module:
-<code java [enable_line_numbers="true"]>
-VillagerEntityAccessor.setMemoryModules(new ImmutableList.Builder<MemoryModuleType<?>>()
-				.addAll(VillagerEntityAccessor.getMemoryModules()).add(MOSQUE_POINT).build());
-</code>
-Once you have a task, you can create a set of tasks (aka Activity):
-<code java [enable_line_numbers="true"]>
-	public static ImmutableList<Pair<Integer, ? extends Task<? super VillagerEntity>>> createPrayTasks(float speed) {
-		return ImmutableList.of(
-				Pair.of(1, new FindTempleTask()),
-				Pair.of(2, new VillagerWalkTowardsTask(
-						MOSQUE_POINT, speed, 1, 150, 1200//info about how to do the task
-				)),
-				Pair.of(3, new ForgetCompletedPointOfInterestTask(BELIEVER, MOSQUE_POINT)),
-				Pair.of(3, new PrayVillagerTask()),//Another task, remove it if you dont want it.
-				Pair.of(99, new ScheduleActivityTask())
-		);
-	}
-</code>
-Then, you need to add the activity to their brain:
-<code java [enable_line_numbers="true"]>
-@Mixin(VillagerEntity.class)
-public class VillagerEntityMixin {
-	@Inject(at = @At("HEAD"), method = "initBrain(Lnet/minecraft/entity/ai/brain/Brain;)V", locals = LocalCapture.CAPTURE_FAILEXCEPTION)
-	private void initBrain(Brain<VillagerEntity> brain, CallbackInfo info) {
-		VillagerEntity $this = (VillagerEntity) (Object) this;
-		if (!$this.isBaby()) {
-			brain.setTaskList(
-					ReligiousVillagersMod.PRAY,
-					createPrayTasks(0.75F)
-			);
-		}
-	}
-}
-</code>
-And to their schedule:
-<code java [enable_line_numbers="true"]>
-	static {
-		addScheduled();
-	}
-	private static void addScheduled() {
-		ScheduleAccessor.setVillagerDefault(
-				new ScheduleBuilder(Schedule.VILLAGER_DEFAULT).withActivity(10, ReligiousVillagersMod.PRAY).build());//10 is the start time
-	}
-</code>
-If all went well and you have all the accessors, you should be able to put down an emerald block inside a village and villagers will pray before work:
