So I am running into an issue where the lines I drew when calling 'draw_Screen()` are flickering. I tried using doublebuf but that didn't fix the issue for me. If you are wondering what I am trying to achieve, I am trying to move the box (main player) while holding the left click button, hence the 'if left_clicking'
You choose a new random corner coordinate in every frame. This causes the flickering. Pick a random corner once and use the same coordinate in every frame:
random_corner = random.choice(rndCorner)
def draw_screen():
obstacle = pg.draw.line(screen, (0, 0, 0), random_corner, (200, 200), 2)
I'm trying to have the for loop run 5 iterations of the code below it but once it runs once and i try to click the rectangle the code goes unresponsive.
I can't see why this is happening so i'm looking for some help.

I expect the code to run 5 iterations of this little reaction time game but it doesn't even get past the first loop before going unresponsive.
You have to use for event in pygame.event.get(): inside while clicked to get new events from system. Without this you have the same values in event.type and even.button.
Even pygame.mouse.get_pos() can't work correclty because it uses data created by pygame.event.get() (or similar)
If you have event MOUSEBUTTONDOWN, MOUSEBUTTONUP then you have mouse position in event.pos and you don't need pygame.mouse.get_pos()
while not clicked:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
quit()
if event.type == pygame.MOUSEBUTTONDOWN and event.button == 1:
if RectX+75 > event.pos[0] > RectX and RectY+40 > event.pos[1] > RectY:
TimeEnd = time.time()
ReactionTime = TimeEnd - TimeStart
Reaction_times.append(ReactionTime)
clicked = True
EDIT:
You can keep Rectangle position and size in pygame.Rect()
RectX = randrange(50,950)
RectY = randrange(60,513)
rect = pygame.Rect(RectX, RectY, 75, 40)
and then you can use rect instead of (RectX,RectY,75,40)
round_rect(screen, rect, black , 10, 5, white)
and you can use rect to check if you clicked in rectangle rect.collidepoint(event.pos)
if event.type == pygame.MOUSEBUTTONDOWN and event.button == 1:
if rect.collidepoint(event.pos):
TimeEnd = time.time()
ReactionTime = TimeEnd - TimeStart
Reaction_times.append(ReactionTime)
clicked = True
EDIT: working example with other changes - ie. I use pygame.time.wait() instead of time.sleep() and pygame.time.get_ticks() instead of time.time(). Both use miliseconds instead of seconds.

I'm trying to make a pause function I've tested this pause function separately and it seems to be working fine although there is nothing that it can do at the moment but it still shows. However, when I implement it in my game it doesn't work?
I've put it in different places before the while loop and in the while loop. When it's before the while loop the pause function will show first then mess up the game. When it's put in the while loop, it wont show at all even when 'p' is pressed.
What is the issue?

if I click on play button on first menu it should open a menu for users to choose the levels . in the code I wrote , on clicking the play button , the computer is also assuming that I also clicked on the easy button which is placed in the same place as the play button in the level screen.It is directly going to the game loop .
Probably you use mouse.get_pressed() which gives True when you hold button pressed - and it makes problem. Using event MOUSEBUTTONDOWN you get "True" only when button changes state from "not-pressed" to "pressed", but not when you hold it pressed.
But mostly it needs a lot changes in button, especially if you have button in one function.

clock.tick(FPS)
pygame.quit()
I guess this is the most important part:
pygame.draw.rect(screen, RED, rectangle)
Every time I try drawing 5 of them I can't drag any of them. Does anyone have a solution for this?
You can create a list of rectangles and a selected_rect variable which points to the currently selected rect. In the event loop check if one of the rects collides with the event.pos, then set the selected_rect to the rect under the mouse cursor and move it.
I'm using a pygame.math.Vector2 for the offset to save a few lines in the example.
import sys
import pygame as pg
from pygame.math import Vector2
pg.init()
WHITE = (255, 255, 255)
RED = (255, 0, 0)
screen = pg.display.set_mode((1024, 768))
selected_rect = None # Currently selected rectangle.
rectangles = []
for y in range(5):
rectangles.append(pg.Rect(20, 30*y, 17, 17))
# As a list comprehension.
# rectangles = [pg.Rect(20, 30*y, 17, 17) for y in range(5)]
clock = pg.time.Clock()
running = True
while running:
for event in pg.event.get():
if event.type == pg.QUIT:
running = False
elif event.type == pg.MOUSEBUTTONDOWN:
if event.button == 1:
for rectangle in rectangles:
if rectangle.collidepoint(event.pos):
offset = Vector2(rectangle.topleft) - event.pos
selected_rect = rectangle
elif event.type == pg.MOUSEBUTTONUP:
if event.button == 1:
selected_rect = None
elif event.type == pg.MOUSEMOTION:
if selected_rect:
selected_rect.topleft = event.pos + offset
screen.fill(WHITE)
for rectangle in rectangles:
pg.draw.rect(screen, RED, rectangle)
pg.display.flip()
clock.tick(30)
pg.quit()
sys.exit()
