The invention discloses a game control method of a pedal platform structure. A game player stands on a pedal platform, an external acting force is applied to the pedal platform by changing standing positions of both feet, the pedal platform is driven to swing accordingly, and then corresponding rack plates of a first rack transmission component and a second rack transmission component are driven to do linear vertical motion, so that the corresponding servo motor is driven to rotate, a pulse signal when an encoder of the servo motor deviates a setting position of the original point is utilized and converted into corresponding output, and the output is sent to an external game equipment computer control assembly to drive a game scene to be continuously carried out. The game control method disclosed by the invention has the advantages that a novel rack plate transmission structure is adopted, and adjustable lock shaft torque of the servo motor is utilized, so that the pedal platform can overcome an external force and restore a horizontal state while the player keeps the balance of gravity center of the both feet, the feet still feel resistance when treading on the pedal platform, but the resistance is balanced, stable and reliable; meanwhile, structure is simple, disassembly and assembly are convenient, wear is hardly caused, stress is uniform and change is small.
