Classes?

[mrgrim333]

How would I got about setting up classes in as2?
I've used them in c++, but never flash.

I want to have like:

class plants
{
public:
  int number;
  int age;
  int water;
};

then use it like:

plant 1;
1.number = 5;
1.age = 100;
1.water = 50;

AS3:

class

package
{ //your class goes in a package definition, 1 class per package, but you can define helper classes outside the package bounds

//import flash.display.*; is similar to #include is c++
 public class plants
  {
    public var 
    nmber:int,
    age:int,
    water:int; //you might wanna define a constructor here to initialize those vars
  }
}

usage

var p1 =  new plants();
p1.number = 5;
p1.age = 100;
p1.water = 50;

1 class per package

This is false. It is only one class per file. Say your document class is in a file called D:\MyGame\bin\DocumentClass.as and your swf will be created in D:\MyGame. The package of DocumentClass.as is than bin, as the swf's location will be treated as a root.

D:\MyGame\bin\DocumentClass.as

package bin
{
	public class DocumentClass extends MovieClip
	{
		
		public function DocumentClass():void 
		{
			//
		}
	}
}

Now say I have a physics package with all my physics functions. I'll have to store it in it's own folder (every package needs it's own folder). Say it contains a rigidbody class and a collisiondetection class. It is located in D:\MyGame\bin\Physics

D:\MyGame\bin\Physics\rigidBody.as

package bin.Physics
{
	public class rigidBody
	{
		
		public function rigidBody():void 
		{
			//
		}
	}
}

D:\MyGame\bin\Physics\collisionDetection.as

package bin.Physics
{
	public class collisionDetection
	{
		
		public function collisionDetection():void 
		{
			//
		}
	}
}

If you wish to import something in a class the file holding the class is considered root. So if you'd wish to import collisionDetection into the DocumentClass you'd use import Physics.collisionDetection. If you would wish to import the rigidBody into the collisionDetection class you'd simply use import rigidBody.

You may want to look up acces-control modifiers in that case too bluemagica.

//your class goes in a package definition, 1 class per package, but you can define helper classes outside the package bounds

I usually do the same, but, you can have more than one class with the same package and thats the point, classes that are somehow related can all be organized and imported at the same time

I normally use something along the lines of:

com
   hsg
      Application.as // launched after preload in Doc class
      doc
         DocumentClass.as
      ui
         HUD.as
         // additional custom display object classes here
      util
         // helper classes here

so the packages would be something like...

• com
• com.hsg
• com.hsg.Application
• com.hsg.doc.DocumentClass
• com.hsg.ui.HUD
