    <p>I always solved the problem like this: (a partial solution):</p> <pre><code>for event in pygame.event.get(): if event.type == pygame.QUIT: pygame.quit() if event.type == KEYDOWN: if event.key == K_ESCAPE: pygame.quit() sys.exit() if event.key == pygame.K_LEFT: x_speed=3 if event.key == pygame.K_RIGHT: player.moveright() x_speed=-3 if event.key == pygame.K_UP: y_speed=3 if event.key == pygame.K_DOWN: y_speed=-3 if event.type == pygame.KEYUP: if event.key == pygame.K_LEFT and x_speed == 3: x_speed=0 if event.key == pygame.K_RIGHT and x_speed == -3: x_speed=0 if event.key == pygame.K_UP and y_speed == 3: y_speed=0 if event.key == pygame.K_DOWN and y_speed == -3: y_speed=0 </code></pre> <p>This doesn't stop movement when the previous key has been unpressed.</p> <p>EDIT: It is not impossible, its just not that useful. You could for example have 2 lists that would imitate a stack. When the list is empty your character will not move. With each keydown, you append the key to the end of list. Every keyup, you remove the key from the list. That way, the most recent key pressed will be at the end of the list, and if you unpress the last recent will also be at the end of the list.</p> <p>A small example:</p> <pre><code>keylist = [] for event in pygame.event.get(): if event.type == KEYDOWN: if event.key == pygame.K_LEFT: keylist.append(-1) if event.key == pygame.K_RIGHT: keylist.append(1) if event.type == pygame.KEYUP: if event.key == pygame.K_LEFT: keylist.reverse().remove(-1) if event.key == pygame.K_RIGHT: keylist.reverse().remove(1) </code></pre> <p>the in the move method you try this: You get the last element in the list if it exists, move the character in the right direction.</p> <pre><code>if(not keylist[-1:]): character.move(direction=keylist[-1]) else: character.move(direction=0) </code></pre>

    1. COThanks for the input. With your method it is more consistent, but what is happening is when you, for example, click right, you start going right, then you click left for a moment and release left while still clicking right, it wont continue right. It will just stop, and the user needs to repress an input again. What Im wanting is a way to prioritize key input, so whatever key i press most recent takes priority, and then when i release that key, if im holding any other directional key down it will then take priority and move me in that direction. Im starting to think it isnt possible!

    2. COyou could also append all the keys from the input, and the look through the list to find the most recent one that is in the same category for example up and down keys.

    3. COThanks I will give that method a try next. I appreciate it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
