Problem with classes and oop basics.

Question

I got a main class called "controll class":

There I addChild a btn to the stage and create a listener for click on that btn.

When clicked the function animated the curretn clip on the stage and moves it out and addChild another movieclip

called Levels_BG

Levels_BG contains at attached and controled but its onwl class: Levels_BG

Which creates a number of 'boxs' on the stage that can be clicked to select a level.

I am tryin to achieve this:

a level box is clicked in the Levels_BG and I need to pass this variable to another class.

Any help appriciated. sry if this is confussing.

Cheers Pavel

I changed my function in control_Class:

static public function startlevel ():void

{

trace("from that class to this one")

}

control_Class.startlevel();

thx for the help.

there are a number of ways to communicate among classes. deciding which is best depends on some specifics.

for example, is there a simple relationship between Levels_BG and your other class? eg, did your other class created the Levels_BG instance?

is there no simple relationship? for example, i often use Data class contains information that needs to be shared among several other classes like a setup class where a user selects parameters and those parameters are used in other classes to control the app. in that situation, using a singleton Data class or static Data class makes sense.

i've never used more than one static/singleton class per app so most communication is not done via this global-type class. some people think static/singleton classes should never be used. but, i think, those are mostly teacher-types, not doers.
