TEXT_NORTH	North direction as a string "[1]"
TEXT_SOUTH	South direction as a string "[2]"
TEXT_EAST	East direction as a string "[4]"
TEXT_WEST	West direction as a string "[8]"
REVERSE_DIR	Inverse direction, taking into account UP\|DOWN if necessary.
MAPPING_DIRECTIONAL_HELPERS	Create directional subtypes for a path to simplify mapping.
MAPPING_DIRECTIONAL_HELPERS_ROBUST	When you need to prescribe very specific offsets, use this over MAPPING_DIRECTIONAL_HELPERS
MAPPING_DIRECTIONAL_HELPERS_ROBUST_INVERSE_DIR	Like the above, but the atom's DIR value will be the opposite of it's offset. i.e the /north type will have dir = SOUTH.

Define Details

Create directional subtypes for a path to simplify mapping.

When you need to prescribe very specific offsets, use this over MAPPING_DIRECTIONAL_HELPERS

Like the above, but the atom's DIR value will be the opposite of it's offset. i.e the /north type will have dir = SOUTH.

Inverse direction, taking into account UP|DOWN if necessary.

East direction as a string "[4]"

North direction as a string "[1]"

South direction as a string "[2]"

West direction as a string "[8]"
