matches

public @Nullable BlockPattern.BlockPatternMatch matches(LevelReader level,
 BlockPos origin,
 Direction forwards,
 Direction up)

matches

private @Nullable BlockPattern.BlockPatternMatch matches(BlockPos origin,
 Direction forwards,
 Direction up,
 LoadingCache<BlockPos, BlockInWorld> cache)

Checks that the given pattern invalid input: '&' rotation is at the block coordinates.

find

public @Nullable BlockPattern.BlockPatternMatch find(LevelReader level,
 BlockPos origin)

Calculates whether the given world position matches the pattern. Warning, fairly heavy function.

Returns:

a BlockPatternMatch if found, null otherwise.

createLevelCache

public static LoadingCache<BlockPos, BlockInWorld> createLevelCache(LevelReader level,
 boolean loadChunks)

translateAndRotate

protected static BlockPos translateAndRotate(BlockPos origin,
 Direction forwardsDirection,
 Direction upDirection,
 int right,
 int down,
 int forwards)

Offsets the position of pos in the direction of finger and thumb facing by offset amounts, follows the right-hand rule for cross products (finger, thumb, palm)

Returns:

a new BlockPos offset in the facing directions
