enum STEP doesn't contain slope information #89
Description
The STEP enum only contains information on whether two nodes are connected by a step or not.
enum STEP {
NOT_CONNECTED = 0, ///< No connection between parent and child.
NONE = 1, ///< Parent and child are on the same plane and no step is required.
UP = 2, ///< A step up is required to get from parent to child.
DOWN = 3, ///< A step down is required to get from parent to child.
OVER = 4 ///< A step over something is required to get from parent to child.
};
This should ideally contain elements such as "upslope," "downslope," etc.
