Examples with ChangeBlock org.spongepowered.common.event.tracking.context.transaction.block.ChangeBlock used on opensource projects

Example 1 with ChangeBlock

use of org.spongepowered.common.event.tracking.context.transaction.block.ChangeBlock in project SpongeCommon by SpongePowered.

the class TransactionSink method logBlockChange.

default ChangeBlock logBlockChange(final SpongeBlockSnapshot originalBlockSnapshot, final BlockState newState, final BlockChangeFlag flags) {
    final ChangeBlock changeBlock = new ChangeBlock(originalBlockSnapshot, newState, (SpongeBlockChangeFlag) flags);
    this.logTransaction(changeBlock);
    return changeBlock;
}

Example 2 with ChangeBlock

use of org.spongepowered.common.event.tracking.context.transaction.block.ChangeBlock in project SpongeCommon by SpongePowered.

the class LevelChunkMixin_Tracker method bridge$createChunkPipeline.

/**
 * Technically a full overwrite for {@link LevelChunk#setBlockState(BlockPos, BlockState, boolean)}
 * and due to Sponge's hijacking of {@link ServerLevel#setBlock(BlockPos, BlockState, int)},
 * it needs to be able to record transactions when necessary. This implementation allows for us to
 * further specify the types of transactions and what proxies are needing to set up where.
 *
 * @param pos The position changing
 * @param newState The new state
 * @param currentState The current state - passed in from either chunk or world
 * @param flag The sponge change flag, converted from an int to a proper struct
 * @return The changed block state if not null
