Instance Method Details

#answer_feedback ⇒ Object

Numeric answers cannot be paired with their comment through a varequal, the way the base implementation does it: exact and precision answers nest it inside an or, and range answers have no single value to emit one for. Canvas instead puts each answer's displayfeedback in the same respcondition that carries its setvar SCORE, so pair them by that node and key the result on the position within answer_nodes -- the same list, in the same order, that scoring_data_structs is built from.
