    <p><strong>Hello!</strong></p> <p>I don't really get what you mean by "<strong>Anonymous</strong>", but one of the solutions is to create so-called <strong>hitboxes</strong>.</p> <p>Let us assume you have an Enemy class:</p> <pre><code>public class Enemy { public var hitBox:Sprite = new Sprite() ; public function Enemy() { hitBox.graphics.clear() ; /* Not filled by a color, as needs to be invisible */ hitBox.graphics.drawRect(x,y,width,height) ; /* Adjust the parameters manually */ this.addChild(hitBox) ; } } </code></pre> <p>There are a lot of enemies, so just create enemyArray and push the enemies into it. And here goes the player's bullet:</p> <pre><code>public class PlayerBullet extends Sprite { private var stageReference:Stage ; public function PlayerBullet(coord:Point, stageReference:Stage){ this.x = coord.x ; this.y = coord.y ; this.stageReference = stageReference ; this.stageReference.addChild(this) ; this.addEventListener(Event.ENTER_FRAME, loop) ; } private function loop(e:Event){ /*Provide some movement for bullet by changing or incrementing this.x and this.y as you wish */ for (var i:Number = 0 ; i &lt; enemyArray.length ; i++){ if (this.hitTestObject(enemyArray[i].hitBox)) { enemyArray.splice(i,1) ; /* Remove the enemy from enemy array on collision */ this.stageReference.removeChild(this) ; /* Do not display bullet anymore on collision with enemy */ } } } } </code></pre> <p>Note: the hitboxes do provide only some square area. If you need some exact detailes of the collision, create several hitboxes.</p> <p>I hope, this will help ! :)</p>

    1. COThe hitTest itself is no problem for me. What I mean with anonymous is I gave no variable name to the object when I created it. I is simply made, and added to the main container. But thanks anyway! :)

    2. COAlright, all you do is just perform: enemyArray.push(new Enemy()) So, your enemies will not be named, but will have their own index in the array, so you can trace them and their properties :) You are welcome!

    3. COI did something similar to what you suggested. I used a Vector, and a simple for each to go through the vector. It gets mad laggy when the amount of enemies on screen gets a lot (>1000) but this was only for demonstration purposes, so it's fine.

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.
