look create_info_labels a function where string 'MARIO' is how to display on the interface.
create_label function parameters (x, y) represents the start position of the string at the interface, to obtain a corresponding object from self.image_dict Surface according characters.
set_label_rects function sets a value for each string of Surface objects rect (x, y).
pygame.Rect common object member variables (x, y), it represents the position of the upper left corner of the Surface.
top, bottom: Surface y-axis represents the uppermost and lowermost values, the top and y values are the same as
left, right: Surface x-axis represents the leftmost and rightmost value, the left and the value of x is same
