Display a power indicator above the player head

Hello and it has been a very long time I am not posting anything on this website and today I am just going to finish up the unfinished business from the previous python project, which is to display a power indicator above the player head to show that the player is in full power after he has eaten the mana during the game, if he collides with the enemy then that power will be used up and the power indicator will disappear. I am using the self.weak switch to indicate whether the player has eaten a mana or is he collides with an enemy. In this example, we will only edit one file, which is the boy sprite class.

from BoyObject import BoyObject
from pygame import math as mt
from pygame.locals import *
from GameSprite import GameSprite
import pygame

class BoySprite(object):

    def __init__(self, scene, level, enemy_manager, mana_manager, level_manager, score_manager):

        self.row = 10
        self.column = 10
        self.scene = scene # game scene instance
        self.space = 64 # image width and height
        self.level = level # current game level
        self.enemy_manager = enemy_manager # the reference of enemy manager
        self.mana_manager = mana_manager # the reference of mana manager
        self.score_manager = score_manager # the reference of score manager
        self.WIDTH = 640

        self.prepare_boy(self.level)

            pygame.draw.rect(self.scene, Color(0, 0, 225, 0), Rect(self.x+12, self.y-10, 10, 10), False)

If we run the above program again then we will see the following outcome.

With that, we have finally concluded the 2 months long project which costs me around 1000 hours of hard work and we will now looking forward to a new chapter of the game development, as I have mentioned before, we will create a new pygame project in the coming future. If you want to help this site out, kindly do consider to donate to this website, thank you in advance!
