DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
Figure 1 is a perspective view showing an embodiment of a train driving simulation game machine to which the image processing system according to the present invention.
An operation unit and a display unit 2 are installed on the front surface of the chair 10 on which the player sits.
A bass shaker 9 that outputs a relatively low sound such as a bang or a bang generated when the train travels is incorporated under the chair 10.
[0006]
Speakers 12 are provided on the left and right of the display unit 2, and a title panel 7 is provided on the top. An overhead wire voltmeter 11, a speedometer 5, and a brake pressure gauge 6 are arranged in the operation section.
The train can be driven by a mascon (master control) lever 3 and a brake lever 4. When the mascon lever 3 is pulled forward, it can be accelerated from the stopped state, and when the brake lever 4 is rotated counterclockwise as viewed from above, the braking effect is increased from the brake released state.
A horn pedal 8 for emitting a horn is provided at the foot.
[0007]
When a coin is inserted from a coin insertion slot (not shown), a screen for selecting a route and a round (train type) is displayed on the screen and can be selected by an operation device 23 (see FIG. 2) (not shown).
After you select the type of route and train, it is possible to advance the simulation of train operation by pressing the start button.
[0008]
FIG. 2 is a block diagram showing an embodiment of a circuit of the game machine of FIG.
When a coin is inserted into the coin related device 22, it is transmitted to the CPU 14 via the input / output control device 24, and the game is started. The backup memory 13 stores setting values such as the number of coins and the number of plays. The CPU 14 reads a program for controlling the entire game from the ROM 18 and controls the image processing unit 21 according to the read program to display an initial screen on the CRT 2.
The work RAM 17 is an area for temporarily storing data when the CPU 14 performs an operation.
[0009]
The communication RAM 15 stores instructions from the CPU 14 regarding sound, and is used when the CPU 14 confirms the sound status.
Sound is generated by the sound system circuit 16, and various sounds and sounds during driving are output from the speaker 12 and the bus shaker 9.
The ROM 18 has a map data memory unit 19 for storing map data for creating an image of a railway line entering the field of view of the driver of each train line, in addition to a program for controlling the entire game. In addition, checkpoint data memory units 20-1 to 20-n are stored that store a large number of checkpoint data tables indicating whether the vehicle stops or passes at a midway station.
[0010]
FIG. 3 is a diagram illustrating an example of a table in which checkpoint data indicating passage and stop of a section station is written.
This example is a table showing the stop and passage of each station between Kyoto Station and Osaka Station on the Tokaido Line, and the type of train is express.
FIG. 4 is a diagram illustrating still another example of train types.
This is a table for stopping all the stations between Kyoto Station and Osaka Station in the case of driving by ordinary train on the same route as FIG. 3, ie, map data.
[0011]
FIG. 5 is a flowchart illustrating an example of a driving operation process at each check point (halfway station).
As described above, when a coin is inserted and the game is started, an image for selecting a route and a train type is displayed on the screen under the control of the CPU 14. When the type of route and train is determined by the operation device 23 (step (hereinafter referred to as “S”) 401), the CPU 14 next reads out the map data of the route and the checkpoint data table of the train type, and the driver at the starting station. Display the field of view.
[0012]
Pressing the start button in this state, since the train operation simulation is started, the player becomes to increase the speed and start by operating the master control lever 3 to release the brake lever 4. During this operation, the CPU 14 determines whether or not the station is approaching on the way (S402). If you are approaching within a certain distance, is the next halfway station a transit station? Is it a stop? Is determined from the table (S403). Since the next station name and stop / pass indication are displayed on the screen, if the vehicle stops according to the display, the player operates the brake lever 4 and the mascon lever 3 to perform the stop operation . CPU14 performs the stop process according to a player's stop operation (S404). If the vehicle passes, the player controls the vehicle to a predetermined speed without stopping and performs an operation of passing through the station on the way . The CPU 14 performs a passing process according to the passing operation of the player (S405).
[0013]
When the vehicle passes or stops at the intermediate station, the CPU 14 increments the built-in checkpoint counter by one. Based on this checkpoint counter value, it is possible to determine the position on the route.
Next, it is determined whether or not a preset time has been exceeded (S407). If the game is not over, it is determined whether or not the final station has been reached (S408). When arriving at the final station, the CPU 14 ends the check point determination. If it has not arrived at the final station, the process returns to S402 to determine the next checkpoint.
[0014]
【The invention's effect】
As described above, the present invention has a mass control lever that can operate the acceleration / deceleration of the train and a brake lever that can operate the braking of the train, and the train starts from the starting station according to the operation of each lever by the player and moves the track. Change the landscape image that is displayed on the screen as it progresses and display it from the cab , display the check details determined for the station on the way, and perform image processing in response to the player's operation of the master control lever and brake lever In the image processing method of the train driving simulation game machine , it corresponds to the map data memory circuit that stores the map data for creating the image of the railway along the line of sight of the driver of each train line , and each map data halfway station either through the way station for each way station and plurality have a table of data stops are written And E click point data memory circuit, an input means for selecting a round showing the train type, read from the checkpoint data memory circuit round correspondence table selected by the input means, for each way station of map data, Control means for controlling the image processing unit in response to the operation of the master control lever and the brake lever of the player, which is performed based on the data read from the table whether the vehicle passes or stops on the way. .
Therefore, it is possible to form a large number of rounds with a small amount of map data, and to increase the number of game rounds in a short work time.
The simulation game operating the train can be configured express, a number of rounds, such as express the less data that multiple tables with one railway map data and the check point data.
