TWO-DIMENSIONAL IMAGE GENERATION PROGRAM, RECORDING MEDIUM WITH TWO-DIMENSIONAL IMAGE GENERATION PROGRAM RECORDED AND TWO-DIMENSIONAL IMAGE GENERATION SYSTEM, AND PACHINKO GAME MACHINE, SLOT MACHINE, OR GAME MACHINE INCLUDING GAMING MACHINE

PROBLEM TO BE SOLVED: To generate a moving image in which an object image drawn in a two-dimensional virtual area is changed to an optional state desired to be changed.SOLUTION: A two-dimensional image generation program makes a computer execute the following steps. An object image is created by arranging the image of each part within a two-dimensional virtual area displayed in a display device, a feature point is set at a plurality of places in the object device, and a control point common to the plurality of feature points and a linkage condition of the feature points are set (S101 to 103). An object image changed by linking the feature points is generated in each display period according to feature point operation linkage information calculated based on feature point operation information about an operation of the feature points and the linkage condition, and the object image is displayed in the display device (S104 to 108).
