MouseDown - occurs when a mouse button is pressed

it should still fix some issue Sorry for replying late, was testing actually ;) Try SOMETHING(modify the logic according to your needs) like this:

code :

$('body').click(function(e){ $('body').append($('<input />').css({position:'absolute',left:e.pageX,top:e.pageY}).focus());})

Click mouse and draw fixed rectangle at mouse position in Video (python_opencv)

hop of those help? The problem is that you fixed a point of the rectangle and the other point follows the mouse. In your code it would be here:

code :

cv2.rectangle(frame,(200,cy),(cx,128),(0,0,255),0)

cv2.rectangle(frame,(cx,cy),(cx + 80, cy +80),(0,0,255),0)

import numpy as np
import cv2 

drawing = False
point = (0,0)

def mouse_drawing(event, x, y, flags, params):
     global point, drawing
     if event == cv2.EVENT_LBUTTONDOWN:
        drawing = True
        point= (x, y)

cap = cv2.VideoCapture(0)
cv2.namedWindow("Frame")
cv2.setMouseCallback("Frame", mouse_drawing)

while True:
   _, frame = cap.read()
   if drawing :
      cv2.rectangle(frame,point,(point[0]+80, point[1]+80),(0,0,255),0)

   cv2.imshow("Frame", frame)
   key = cv2.waitKey(25)
   if key== 13:    
     print('done')
   elif key == 27:
     break

 cap.release()
 cv2.destroyAllWindows()

def mouse_drawing(event, x, y, flags, params):
     global point, drawing
     if event == cv2.EVENT_LBUTTONDOWN:
        drawing = True
        point = (x, y)
     elif event == cv2.EVENT_MOUSEMOVE:
       if drawing is True:
        point = (x, y)
    elif event == cv2.EVENT_LBUTTONUP:
        drawing = False
        point = (x, y)

How do I select a sprite on a first mouse click then create a new one in the position of a second mouse click

With these it helps You don't need to wait for a second click. You need to be able to understand if, when clicking, the program should select the sprite or create a new one.
A way to do this is to create a variable selected_sprite. If this variable is equal to None, that means that the click must select a sprite. It this variable holds a sprite, you can create a copy of it (or just a new sprite) at the new position.

code :

addBarrierButton = Barrier()

addBarrierButton.rect.x=800
addBarrierButton.rect.y=400

all_sprites_list = pygame.sprite.group()
all_sprites_list.add(addBarrierButton)
all_sprites_list.draw(gameDisplay)

selected_sprite = None

#Main loop
while True:
    for event in pygame.event.get():
        if event.type = pygame.MOUSEBUTTONDOWN:
            if selected_sprite is None:
                for spr in all_sprites_list:
                    if spr.rect.collidepoint(event.pos):
                        selected_sprite = spr
                        break
            else:
                new_sprite = Barrier()
                new_sprite.image = selected_sprite.image
                new_sprite.rect.x = event.pos[0]
                new_sprite.rect.y = event.pos[1]
                all_sprites_list.add(new_sprite)
                selected_sprite = None
