    <p>I'm creating a game where if you hit a zombie the zombie dies and his head is sent back in the direction you hit. It is like playing baseball with the zombies head with the head being the ball. I have two movieclips the zombie and the zombie head. Once the zombie is hit it will play its dying animation and remove itself and at the same time the zombie head will be added to the x and y co-ordinates of the dying zombie and be blown back like playing baseball. I have done the code for the hittest and the zombie dying and respawning but I can't seem to position and add the head to the dying zombie when it is hit. I have done the function for the zombie head but how can I add it to the zombie. I thought it will be like this, I added this in the PlayDeathAnimation function in the zombie class but did not work:</p> <pre><code>for (var i=0; i &lt; MovieClip(parent).zombies.length; ++i) { var zh = new ZombieHead(); zh.x = MovieClip(parent).zombies[i].x; zh.y = MovieClip(parent).zombies[i].y; zh.rotation = MovieClip(parent).zombies[i].rotation; addChild(zh); } </code></pre> <p>I even tried just this. The head does spawn but just stays static and does not fly back and it removes itself when the zombie removes itself which I don't wan't. I have already told the ZombieHead when to remove itself in its own class</p> <pre><code>var zh = new ZombieHead(); addChild(zh); </code></pre> <p>This is what i done so far Player</p> <pre><code>package { import flash.display.MovieClip;

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.
