  • a rectangular 3D map 3DM is virtually (imaginarily) formed such that four comers thereof are located on straight lines originating from the viewpoint E and passing through four corners of the image G.
  • the 3D map 3DM is placed in parallel with the image G at a backward position seeing from the viewpoint E.
  • the 3D map 3DM is virtually disposed such that an X-Y plane (a plane including X and Y axes) thereof is set in parallel to the image G which is two-dimensional.
  • This 3D map corresponds to the display map M displayed on the display unit.
  • the specified position determining unit 131 C uses, for example, 3D map data obtained from the 3D map recorder 131 D via the map data generator 131 A in order to form the 3D map 3D virtually.
  • map data generator 131 A uses the above data in generating combat element data after deciding destinations of combat elements S 1 , S 1 .
  • the above data can be used to generate image data for displaying a small region S 1 specified by the cursor C at the current point on the display unit as distinguished from other small regions S 1 , S 1 , . . . .
  • This can be attained by, for example, making a difference in color between the small region S 1 and other regions S 1 , S 1 . . . or adding some pattern to the small region S 1 though the illustration is omitted.
  • Data generated in this case is capable of displaying such a color and a pattern.
  • the image displayed on the display unit in the normal state is displayed based on image data generated when the data generator 133 combines map data, combat element data and cursor data generated as mentioned above.
  • a determination whether or not a predetermined condition about the start of combat is satisfied is performed (S 203 ). For example, this condition is satisfied when the game player inputs the operation content, which corresponds to the instructions in which the predetermined player's combat elements S 1 , S 1 are fought with the opponent's combat elements S 1 , S 1 , via the control unit 81 or when the normal state controller 122 supports the start of combat in accordance with the predetermined condition.
  • the determination whether or not this condition is satisfied is performed by, for example, the selector 121 .
  • This image is displayed on the display unit in accordance with image data, which the data generator 133 has generated based on data determined by the combat state image determining unit 132 under control of the combat state controller 123 .
  • This image shows that the player's combat element executes an action in real time in accordance with the operation content inputted by the game player.
  • the data generator 133 generates combat image data to display the player's combat element S 1 , which executes a combat in accordance with the operation content inputted by the game player among the player's combat elements S 1 , S 1 , and the opponent's combat element S 1 fighting with the player's combat element S 1 in real time.
  • the player's combat element S 1 is displayed on the screen in real time in accordance with the operation content inputted by the game player.
  • the image as a moving image using a polygon is displayed on the display unit.
  • FIG. 8 One example of the image displayed on the display unit in the combat state is illustrated in FIG. 8.
  • the aforementioned combat data is inputted to the combat state controller 123 .
  • This data is also sent to the distance detector 123 A provided in the combat state controller 123 .
  • the distance detector 123 A Upon receipt of this data, the distance detector 123 A detects a distance between the player's combat element S 1 , which executes the combat, and the opponent's combat element S 1 so as to generate distance data of the distance.
  • This distance denotes, for example, a distance between both combat elements S 1 on the 3D map 3DM.
  • Distance data may be one that is proportional to the distance between both combat elements S 1 .
  • two kinds of different distance data are generated depending on whether both combat elements S 1 , which are to fight with each other, are placed at the small regions M 1 adjacent to each other via the side or at a different position.
  • the distance detector 123 A generates distance data indicating that both combat elements S 1 are placed in a close distance range in the former case and in a long distance range in the latter case.
  • this data is sent to the combat state image determining unit 132 provided in the image data generator 130 .
  • the combat state image determining unit 132 generates image data about the initial image displayed on the display unit in accordance with the distance data at the beginning of the change to the combat state.
  • the combat state image determining unit 132 is configured to generate initial image data for displaying the initial image indicating that both combat elements are in the close distance range as compared with the case in which it receives data indicating that both combat elements are in the long distance range.
  • FIG. 10 shows an example of the initial image in a case (A) in which the combat state image determining unit 132 receives distance data indicating that both combat elements S 1 are placed in the close distance range and that of the initial image in a case (B) the combat state image determining unit 132 receives data indicating that both combat elements are in the long distance range.
  • the soldier displayed at the front indicates the player's combat element S 1 and the solider displayed at the backward is the opponent's combat element S 1 .
  • distance data is data that shows numerous levels (or non-level), which are proportional to the distance
  • the distance between the player's combat element S 1 and the opponent's combat element S 1 can be variously expressed.
  • a 3D map having three-dimensional information and a cursor having only two-dimensional information can be displayed on the same screen page and but also their positions can be figured out, whereby determining as to which position on the 3D map is specified by the cursor.
