public class drop_desire
extends drop_intention

Internal action: .drop_desire(D).

Parameters:

• - desire (literal): the desire to be dropped.

Example:

• .drop_desire(go(X,3)): remove desires such as <+!go(1,3),_> from the set of events and intentions having plans with triggering events such as +!go(1,3).
