    <p>In some places you try to use <code>int</code> value as <code>object</code>:</p> <pre><code>ground = 720 self.y = ground.y # error !!! </code></pre> <p><code>ground</code> is number <code>int</code>(integer) not object with <code>.y</code></p> <p>You could use <code>pygame.Rect()</code></p> <pre><code>ground = pygame.Rect(0, 750, 0, 0) # (x, y, width, heigh) </code></pre> <p>and then you can use <code>ground.x</code>, <code>ground.y</code>, and others - see <a href="http://www.pygame.org/docs/ref/rect.html" rel="nofollow">pygame.Rect()</a>.</p> <p>.</p> <hr> <p>btw: you should move <code>#Movement</code> code, <code># Movement variables</code>code, <code># Screen wrap</code> code into <code>Player</code> class as functions and call that functions in main loop - to make main loop more readable.</p> <p><code># Movement variables</code>code, <code># Screen wrap</code> code could be in <code>player.update</code></p> <p><code># Movement</code> code could be in Player class as <code>event_handler(self, event)</code></p> <pre><code>def event_handler(self, event): if event.type == pygame.KEYDOWN: if event.key == pygame.K_a: velX = -5 elif event.key == pygame.K_d: velX = +5 elif event.type == pygame.KEYUP: if event.key in (pygame.K_a, pygame.K_d): velX = 0 </code></pre> <p>(you can use <code>elif</code> as above)</p> <p>Now you can use this in main loop <code>player.event_handler(event)</code></p> <hr> <p><strong>EDIT:</strong></p> <p>I made many modifications in your code - but I had no time to finish it.</p> <p>Player still doesn't jump.

    1. COHello the part with ground fixes the error but now my player is falling through the floor and a few other errors like when I jump my player doesn't stop, he just flies off screen, also when I move all of the movement code the movement stops working. Any suggestions?

    2. COUse `print self.y, ground.y` and you see that player is stopping but below bottom window border. `self.y` is top of player so all player is below `self.y`. With `pygame.Rect()` you could test `self.rect.bottom >= ground.y`. You could also use `self.rect.top`, `self.rect.centerx`, etc. See: [pygame.Rect()](http://pygame.org/docs/ref/rect.html). You can use `self.rect` with `screen.blit` - `screen.blit(self.i0, self.rect)` - and with collision detect ([pygame.Rect.colliderect](pygame.Rect.colliderect), etc., [pygame.sprite.collide_rect](http://pygame.org/docs/ref/sprite.html), etc. ).

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.
