Triangular relation is introduced such that a vertical-attribute attack B1
(first action) is more advantageous than a horizontal-attribute attack B2
(second action); the horizontal-attribute attack B2 is more advantageous
than a movement action B3 (third action); and the movement action B3 is
more advantageous than the vertical-attribute attack B1. If the vertical
and horizontal attribute attacks occur at the same time, hit check is
carried out using pseudo hit areas each of which is larger then than hit
areas specified by the orbits of attacks, the amount of axis following
compensation for character is set to be larger, or the judgment of hit is
canceled even when the attacks hit against each other. If an attribute
parameter (or difficulty level setting) for any one of the
vertical-attribute attack, horizontal-attribute attack, and movement
action is changed, the attribute parameters for the other actions are
also changed at the same time.
