    <p>I am trying to do an example of collision in Action Script 3. It's a <code>character</code> that should stop when it hits a <code>platform</code>. It works well when I move only to the right, left, up or down directions, but if I try to move in the diagonals, if the <code>character</code>is colliding with the <code>platform</code>, the object goes to a different area of the screen.</p> <p>This is the compiled example: <a href="http://dl.dropbox.com/u/5282142/GameDemo.html" rel="nofollow">http://dl.dropbox.com/u/5282142/GameDemo.html</a></p> <p>And below is my code.</p> <p>Now, does anyone know a better way to do what I am doing, or how can I get the character not to go to a weird position when I try to move it in a diagonal?</p> <pre><code>var level:Array = new Array(); for (var i = 0; i &lt; numChildren; i++) { if (getChildAt(i) is Platform) { level.push(getChildAt(i).getBounds(this)); } } var speedX:int = 0; var speedY:int = 0; var kLeft:Boolean = false; var kRight:Boolean = false; var kDown:Boolean = false; var kUp:Boolean = false; stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyDownHandler); stage.addEventListener(KeyboardEvent.KEY_UP, onKeyUpHandler); function onKeyDownHandler(event:KeyboardEvent):void { if (event.keyCode == 37) kLeft = true; if (event.keyCode == 38) kUp = true; if (event.keyCode == 39) kRight = true; if (event.keyCode == 40) kDown = true; } function onKeyUpHandler(event:KeyboardEvent):void { if (event.keyCode == 37) kLeft = false; if (event.keyCode == 38) kUp = false; if (event.keyCode == 39) kRight = false; if (event.keyCode == 40) kDown = false; } addEventListener(Event.ENTER_FRAME, loop); function loop(event:Event):void { moveChar(); bound(); } function moveChar():void { if (kLeft) { speedX = -10; } else if (kRight) { speedX = 10; } else { speedX *= 0.5; } if (kUp) { speedY = -10; } else if (kDown) { speedY = 10; } else { speedY *= 0.5; } character.x += speedX; character.y += speedY; } function bound():void { if (character.x &gt; (800 - character.width/2)){ character.x = 800 - character.width/2; } if (character.x &lt; (character.width/2)){ character.x = character.width/2; } if (character.y &gt; (480 - character.height/2)){ character.y = 480 - character.height/2; } if (character.y &lt; (character.height/2)){ character.y = character.height/2; } for (i = 0; i &lt; level.length; i++) { if (character.getBounds(this).intersects(level[i])) { if (speedX &gt; 0) { character.x = level[i].left - character.width/2; } if (speedX &lt; 0) { character.x = level[i].right + character.width/2; } } } for (i = 0; i &lt; level.length; i++) { if (character.getBounds(this).intersects(level[i])) { if (speedY &gt; 0) { character.y = level[i].top - character.height/2; } if (speedY &lt; 0) { character.y = level[i].bottom + character.height/2; } } } } </code></pre>

    1. COHave you considered using a physics library like Box2D to prevent likely future brain meltdown.

    2. CO@PeterSmith I have, I'm trying to use Box2D with Flash CS5.5. I looked up an error that I came across and there seems to be an issue with Box2D and Flash CS5.5. They tell me to compile again the examples, but it won't work. Running the examples contained in the Box2D package should be simple, right?

    3. COI got Box2D to work by following this tutorial that uses WCK: http://gotoandlearn.com/play.php?id=135

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
