Python & Pygame: Updating all elements in a list under a loop during iteration
- by Unit978
i am working on a program in Python and using Pygame. this is what the basic code looks like:
while 1:
screen.blit(background, (0,0))
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
if event.type == KEYDOWN and event.key == K_c:
circle_create = True
circle_list.append(Circle())
if event.type == MOUSEBUTTONDOWN and circle_create == True:
if clicks == 0:
circle_list[i].center()
clicks += 1
if event.type == MOUSEMOTION and clicks == 1 and circle_create == True:
circle_list[i].stretch()
these if statements are under the while loop not the for loop since they dont require input from the user
if circle_create == True:
circle_list[i].draw_circle()
if clicks == 2:
clicks = 0
i += 1
circle_create = False
pygame.display.update()
what i want to do is have the object's function of draw_circle() to be constantly updated by the loop so that the drawn circle is shown for all objects in the list, but since the list is iterated it updates the new object added and the objects already appended are not updated.
The program, works, it draws the circles upon user input but the update problem is the only issue i need to solve. Is there any possible way to have all elements in the list of objects being updated by the while loop? i have tried for many days and i have not been able to find a good solution. any ideas are appreciated. Thanks
