    <p>Package names are determined by the location from src. <code>src/my/package/name</code> is <code>my.package.name</code>. The package you import at the top of any class <strong>must</strong> match the actual package, otherwise the compiler will not find the class.</p> <p>So... say you have this structure in your folders:</p> <pre><code>src -&gt;my -&gt;package -&gt;name -&gt;ClassName </code></pre> <p>The class would be set up as so:</p> <pre><code>package my.package.name { public class ClassName { public function ClassName(){ //construct } } } </code></pre> <p>And you would import it using:</p> <pre><code>import my.package.name.ClassName; </code></pre> <p>or </p> <pre><code>import my.package.name.*; //only use the wildcard if every class in that package is being used, otherwise you will include code you may or may not need to in your project </code></pre> <p>Hopefully that helps explain packages and imports a bit.</p> <p>I also noticed that you are using the functions in your <code>CustomFuncs</code> class as if they were static (as you would with <code>Math.cos()</code> or similar). Your class is not set up to work this way. To do that, you need to use this <code>static</code> access modifier.</p> <pre><code>package sthreets { public class CustomFuncs { public static function TopDownMove(xy:String, rot:Number, offSet:Number):Number { if(xy=="x") { return cos(DegreesToRadions(rot)+offSet) } if(xy=="y") { return sin(DegreesToRadions(rot)+offSet) } } public static function DegreesToRadions(rot:Number):Number { return rot*Math.PI/180; } } } </code></pre> <p>The static access modifier means that the object (in this case, the functions) only exist once in any instance of the app, whereas a standard access modifier (<code>public</code>, <code>private</code>, <code>protected</code>, <code>internal</code>, <code>mx_internal</code>, <code>final</code>) create one object for every single instance of the <em>class</em>. Using the <code>static</code> access modifier allows you to access objects through <code>ClassName.objectName</code> because the objects belong to the class, not to the parent object. To get to those objects, you never have to instantiate (you will notice in the above code that I removed your constructor because it is unnecessary in this case).</p> <p><strong>Note:</strong> The following isn't necessarily directed at you, but I am including it for any future readers who might visit this question</p> <p>This <a href="http://greenethumb.com/article/27/public-private-protected-internal-access-modifiers-in-as3/" rel="nofollow">blog post</a> gives a fairly good rundown of the standard access modifiers. The comparisons it makes in relation to beer are incredibly good and incredibly easy for someone with limited knowledge about the modifiers to understand.</p> <p>I also suggest reading this <a href="http://en.wikipedia.org/wiki/Static_variable" rel="nofollow">Wikipedia article</a> on "Static Variable" to help you understand what a static object is and where and how to use it.</p> <p>AS3 strictly follows OOP (object oriented programming) and ECMAScript policies and its syntax is based heavily on Java. For these reasons, nearly every principle used by other OOP or ECMA languages applies to AS3 as well. This means that you can improve your AS3 skills by reading up on these principles, even if they are not specifically for AS3 (AS3 OOP tutorials are fairly limited in both quantity and quality so it can be difficult for someone who is learning AS3 as their first OOP language to learn these principles).</p>

    1. COThanks, but how do I set it up if my fla/as files are in a folder on the desktop, but my custom class is also in a folder on the desktop? Also the sin/cos stuff with Math I was planning on debugging later but I intended Math.sin and Math.cos.

    2. COIf they are in your src folder (in this case, the folder on your desktop), the package is the same as your document class. So there is no need to import it and the class should be created as `package{ public class{` without any package name. (Not 100% sure, however, since I have never built a class-based project using Flash Pro, only Flash Builder and Flash Develop. But Pro is just a much more feature-filled IDE so it should work the same)

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.
