Method Details

filterState

public BlockMatcher filterState(Predicate<BlockState> predicate)

filterPosition

public BlockMatcher filterPosition(BiPredicate<BlockState, BlockPos> predicate)

Neo: Filter against the state and position context, after the states are filtered. This is only called for positions that the block state filter did not reject.

All filters registered using this method are applied in sequence, so only the intersection of all filters are matched.

The position passed to this method may be mutable; do not modify it or store it directly without first making it immutable.

For filtering out states without reference to the position, prefer using filterState(Predicate).

Parameters:

predicate - a filter based on state and (mutable) position

Returns:

this matcher, for chaining

atLeastMatched

public abstract boolean atLeastMatched(int n)

atMostMatched

public boolean atMostMatched(int n)

anyMatched
