Drawing device, drawing control method, and drawing control program for drawing graphics in accordance with input through input device that allows for input at multiple points

摘要

A game device includes: an input position acquiring unit for acquiring the position of an input entry to a touch panel capable of concurrently detecting input entries at a plurality of points; a drawing start determination unit for determining, when the respective positions of concurrent input entries to the touch panel at two points are acquired, to start drawing a graphic if a distance between the two points is within a first range; a drawing unit for drawing, while the input entries at the two points continue to be input after drawing a graphic is started, a graphic calculated based on the respective movement trajectories of the two points and displaying the graphic on a display device; and a drawing end determination unit for determining to end drawing the graphic when the input of the input entries at the two points ends.

主权项

1. A drawing control program embedded on a non-transitory computer-readable recording medium, the drawing control program allowing a computer to function as:
an acquiring unit configured to acquire the position of an input entry to an input device capable of concurrently detecting input entries at a plurality of points; a drawing start determination unit configured to determine, when the acquiring unit acquires the respective positions of concurrent input entries to the input device at two points that are start points, that drawing of a graphic is to be started if a distance between the two points is within a first range, wherein the graphic is a newly created graphic; a drawing unit configured to draw, while the input entries at the two points continue to be input after the drawing start determination unit determines that drawing of a graphic is to be started, a graphic calculated based on the respective movement trajectories of the two points and to display the graphic on a display device; and a drawing end determination unit configured to determine that drawing of the graphic is to be ended when the input of the input entries at the two points ends that are end points, wherein a start point and an end point of the graphic are determined by the start points and end point of the input entries.
