Pygame window will suddenly fill with white

Question

I was making a game where you chop trees and that when you chopped down a tree, it would count down from 3 until chopping it. However, during the countdown process the window will all fill with white and nothing can be seen except from the text counting down at the bottom of the screen. After the countdown, everything would return back to normal. Can someone tell me why this is happening? The entire code is below:

import pygame
import time
pygame.init()
root = pygame.display.set_mode((603, 573))
pygame.display.set_caption("Foraging Simulator")

width = 10

height = 20
leaves_height = 10
x = 0
tree_trunk_x = 10
y = 0
tree_trunk_y = 10
vel = 5

        countdown = count.render('3', True, (0, 0, 0))
        root.blit(countdown, (583, 553))
        pygame.display.update()
        time.sleep(1)

Answer 1

It is sufficient to rest the property self.tree_property_name when the tree is destroyed:

class Tree:
    def __init__(self, tree_x, tree_y):
        self.tree_x = tree_x
        self.tree_y = tree_y
        self.tree_property_name = True
        self.trunk = None
        self.leaves = None

    # [...]

    def destroy(self):
        self.tree_property_name = False

Create a list of trees rather than separate variables:

trees = []
for x in range(4):
    for y in range (4):
        trees.append(Tree(x*50, y*50))

Draw the trees in alist:

while window_is_open:
    # [...]

    for tree in trees:
        tree.redraw()

Evaluate if on a tree is clicked in a loop and and start a count_down in seconds:

count_down = 0
destroy_tree = None
while window_is_open:
    delta_time = pygame.time.delay(100)

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            window_is_open = False

        elif event.type == pygame.MOUSEBUTTONDOWN:
            if destroy_tree == None and event.button == 1:
                for tree in trees:
                    if tree.tree_property_name:
                        if tree.trunk.collidepoint(event.pos) or tree.leaves.collidepoint(event.pos):
                            count_down = 3
                            destroy_tree = tree

Destroy the key when the the count has expired:

while window_is_open:
    # [...]

    number = 0
    if destroy_tree != None:
        count_down -= delta_time / 1000
        if count_down > 0:
            number = int(count_down) +1
        else:
            destroy_tree.destroy()
            destroy_tree = None
