getY()

returns: (int) The vertical coordinate of the entity's position.

getResistance(entity)

Retrieves the resistance this entity has on other entities.

entity: (optional) If set, returned value is combined resistance.

returns: (int) Value between 0-100 (0 = no resistance, 100 = non-traversable).

getAdjacentNodes()

Retrieves horizontal & vertical nodes immediately adjacent to entity's current position.

NOTE: This does not compensate for the entity's size. It is only meant to determine the positions the entity could potentially move to.

returns: (List<Node>) All nodes next to entity.

getArea()

Retrieves the area this entity currently occupies.

returns: (Rectangle2D)

getArea(ex, ey)

ex: (double)

ey: (double)

returns: (Rectangle2D)

x: (int) The horizontal position to which distance should be calculated.

y: (int) The vertical position to which distance should be calculated.

returns: (double) Representation of the squared distance.

nextTo(entity, step)

Checks whether the given entity is next to this one.

entity: (Entity) The entity to compare distance to.

step: (double) (default: 0.25) Maximum distance at which is required to determine if next to.

returns: (bool) true if entity is next to this one.
