Pseudo Code for Hill Maze Game

Overview

This pseudo code represents the logic for a simple hill maze game using the Pygame library. It initializes the game, handles user input for sprite movement, and updates the game display accordingly.

Variables and Initialization

• Initialize Pygame
• Set screen dimensions
• Load sprite images for different directions (right, left, up, down)
• Set the initial direction of the sprite and the corresponding sprites
• Define rectangle for boundaries and load the background image
• Initialize sprite properties (position, width, height)
• Define speed and frame rate settings

Main Game Loop

FUNCTION MainGameLoop()
    RUNNING = TRUE
    WHILE RUNNING
        PROCESS_EVENTS()
        HANDLE_INPUT()
        UPDATE_POSITION()
        DRAW_SCREEN()
        UPDATE_DISPLAY()
        CONTROL_FRAME_RATE()
    END WHILE
END FUNCTION

Process Events

FUNCTION PROCESS_EVENTS()
    FOR EACH EVENT IN pygame.event.get()
        IF EVENT.type IS pygame.QUIT THEN
            RUNNING = FALSE
        END IF
    END FOR
END FUNCTION

Handle Input

FUNCTION HANDLE_INPUT()
    GET pressed_keys FROM pygame.key.get_pressed()

    IF pressed_keys[pygame.K_UP] THEN
        SET current_direction TO 'up'
        SET current_sprites TO sprites_up
        INCREMENT current_frame BY 0.2
        INCREMENT background_y BY speed
    ELSE IF pressed_keys[pygame.K_DOWN] THEN
        SET current_direction TO 'down'
        SET current_sprites TO sprites_down
        INCREMENT current_frame BY 0.2
        DECREMENT background_y BY speed
    ELSE IF pressed_keys[pygame.K_LEFT] THEN
        SET current_direction TO 'left'
        SET current_sprites TO sprites_left
        INCREMENT current_frame BY 0.2
        INCREMENT background_x BY speed
    ELSE IF pressed_keys[pygame.K_RIGHT] THEN
        SET current_direction TO 'right'
        SET current_sprites TO sprites_right
        INCREMENT current_frame BY 0.2
        DECREMENT background_x BY speed
    END IF
END FUNCTION

Update Position

FUNCTION UPDATE_POSITION()
    IF background_x < -645 THEN
        INCREMENT background_x BY speed
    END IF
    IF background_x > 305 THEN
        DECREMENT background_x BY speed
    END IF
    IF background_y > -745 THEN
        DECREMENT background_y BY speed
    END IF
    IF background_y < 200 THEN
        INCREMENT background_y BY speed
    END IF

    IF current_frame >= LENGTH(current_sprites) THEN
        SET current_frame TO 0
    END IF
    IF current_frame == 4 THEN
        SET current_frame TO 0
    END IF
END FUNCTION

Draw Screen

FUNCTION DRAW_SCREEN()
    CLEAR SCREEN WITH COLOR (135, 206, 235)
    BLIT background_image AT (background_x, background_y)
    BLIT current_sprites[int(current_frame)] AT sprite_rect
END FUNCTION

Update Display

FUNCTION UPDATE_DISPLAY()
    pygame.display.flip()
END FUNCTION

Control Frame Rate

FUNCTION CONTROL_FRAME_RATE()
    clock.tick(30)
END FUNCTION

Conclusion

This pseudo code outlines the structure and functionality of a simple game using Pygame, focusing on sprite movement and background interaction based on user input. This serves as a foundational design for developing the actual code within a programming environment.
