title: Creating sliders using pygame
body: <p>I am creating a covid simulator and am using sliders to allow the user to adjust the figures such as the amount of people that will stay at home. I have been able to successfully create the sliders, but for some reason when i try to move one they both move. The code i have created goes:</p>
  <pre><code>def saved_sim():
      slider1 = 600
      slider2 = 600
      #size_of_gas_cloud = 400
      running = True
      while running:
          menu.fill(BACKGROUND_COLOR)
          title = Label(menu, &quot;Editting features for simulation&quot;, 1, font_title, BLACK, 330, 30)
          Sub_heading = Label(menu, &quot;Please edit the features using sliders before selecting a location&quot;, 1, font_para, BLACK, 5, 100)
  
          if pygame.mouse.get_pressed()[0] != 0:
              # collision detection also needed here
              slider1 = pygame.mouse.get_pos()[0] - 5
              if slider1 &lt; 600:
                  slider1 = 600
              if slider1 &gt; 800:
                  slider1 = 800
  
          if pygame.mouse.get_pressed()[0] != 0:
              # collision detection also needed here
              slider2 = pygame.mouse.get_pos()[0] - 5
              if slider2 &lt; 600:
                  slider2 = 600
              if slider2 &gt; 800:
                  slider2 = 800
  
          pygame.draw.rect(menu, BLACK, Rect(600, 300, 210, 10))
          pygame.draw.rect(menu, RED, Rect(slider1, 300, 10, 10))
  
          pygame.draw.rect(menu, BLACK, Rect(600, 400, 210, 10))
          pygame.draw.rect(menu, RED, Rect(slider2, 400, 10, 10))
  </code></pre>
  <p>Thanks for any help in advance.</p>
