Example 2 with BlockStateChange

use of com.bergerkiller.bukkit.common.wrappers.BlockStateChange in project BKCommonLib by bergerhealer.

the class PacketPlayOutMapChunkHandle method setBlockStates.

    List<BlockStateChange> baseStates = this.getBlockStates();
    int count = states.size();
    int limit = Math.min(count, baseStates.size());
