      Fires the BlockDropsEvent when block drops (items and experience) are determined.

      Fires BlockEvent.BreakEvent, pre-emptively canceling the event based on the conditions that will cause the block to not be broken anyway.

      Note that undoing the pre-cancel will not permit breaking the block, since the vanilla conditions will always be checked.

      Parameters:
      level - The level

      player - The breaking player
      pos - The position of the block being broken

    • prefixNamespace

      public static String prefixNamespace(net.minecraft.resources.ResourceLocation registryKey)

      This method is used to prefix the path, where elements of the associated registry are stored, with their namespace, if it is not minecraft

      This rules conflicts with equal paths out. If for example the mod fancy_cheese adds a registry named cheeses, but the mod awesome_cheese also adds a registry called cheeses, they are going to have the same path cheeses, just with different namespaces. If additional_cheese wants to add additional cheese to awesome_cheese, but not fancy_cheese, it can not differentiate both. Both paths will look like data/additional_cheese/cheeses.

      The fix, which is applied here prefixes the path of the registry with the namespace, so fancy_cheese's registry stores its elements in data/<namespace>/fancy_cheese/cheeses and awesome_cheese's registry stores its elements in data/namespace/awesome_cheese/cheeses

      Parameters:
      registryKey - key of the registry
      Returns:
      path of the registry key. Prefixed with the namespace if it is not "minecraft"

Additionally, when the entity is underwater it will dismount if IEntityExtension.canBeRiddenUnderFluidType(FluidType, Entity) returns false.
      Parameters:

      public static boolean tryDispenseShearsHarvestBlock(net.minecraft.core.dispenser.BlockSource source, net.minecraft.world.item.ItemStack stack, net.minecraft.server.level.ServerLevel level, net.minecraft.core.BlockPos pos)
      Attempts to modify target block using ItemAbilities.SHEARS_HARVEST in ShearsDispenseItemBehavior, consistent with vanilla beehive harvest behavior (also controlled by ItemAbilities.SHEARS_HARVEST).

      The beehive harvest behavior is not implemented by IBlockExtension.getToolModifiedState(BlockState, UseOnContext, ItemAbility, boolean) and thus will still be controlled by ShearsDispenseItemBehavior.tryShearBeehive(ServerLevel, BlockPos) by default.

      Mods may subscribe to BlockEvent.BlockToolModificationEvent to override vanilla beehive harvest behavior by setting a non-null BlockState result.
