Example 3 with PipelineCursor

use of org.spongepowered.common.event.tracking.context.transaction.pipeline.PipelineCursor in project SpongeCommon by SpongePowered.

the class ServerLevelMixin_Tracker method shadow$removeBlockEntity.

/**
 * Technically an overwrite, but because this is simply an override, we can
 * effectively do as we need to, which is determine if we are performing
 * block transactional recording, go ahead and record transactions.
 * <p>In the event that we are performing transaction recording, the following
 * must be true:
 * <ul>
 *     <li>This world instance is managed and verified by Sponge</li>
 *     <li>This world must {@link LevelBridge#bridge$isFake()} return {@code false}</li>
 *     <li>The {@link PhaseTracker#SERVER}'s {@link PhaseTracker#getSidedThread()} must be {@code ==} {@link Thread#currentThread()}</li
 *     <li>The current {@link IPhaseState} must be allowing to record transactions with an applicable {@link org.spongepowered.common.event.tracking.context.transaction.TransactionalCaptureSupplier}</li>
 * </ul>
 * After which, we may be able to appropriately associate the {@link net.minecraft.world.level.block.entity.BlockEntity}
 * being removed with either an existing {@link ChangeBlock},
 * or generate a new {@link RemoveBlockEntity} transaction
 * that would otherwise be able to associate with either the current {@link IPhaseState} or a parent {@link GameTransaction}
 * if this call is the result of a {@link org.spongepowered.common.event.tracking.context.transaction.effect.ProcessingSideEffect}..
 *
 * @param pos The position of the tile entity to remove
