PROBLEM TO BE SOLVED: To simplify a description of a program without performing a complicated judging method each time in a structure of a background picture to discribe a map by performing picture image processing on the basis of an attribute value of an image element of the background picture corresponding to an attribute value of a player character. SOLUTION: When a player character PC stays on an upper road, it is defined as 30, and when he stays on the ground surface, it is defined as 10. A bridge is shown by 20, and when an attribute of PC is 10, the non-passage is shown by 11, and when an attribute of the PC is 30, the non-passage is shown by 31. When an attribute of the PC is 10, map attributes 20 and 31 of an upper layer are not influenced. When an attribute of the PC is 30, a map attribute 11 of a lower layer is not influenced. Here, since 01 of a drawing shows the overall non-passage, passing cannot be allowed regardless of a lower layer and an upper layer. Since these map attributes 11, 20 and 31 are simultaneously set when a background is defined, when the PC comes to its cell on a program, whether or not passing is allowed can be judged only by checking an attribute of the PC and an attribute of a map. |
