accessing classes from classes

[silverswim]

Hi... I'm having some trouble with these bits of code... I got some help before from wangbar to sort it out when the var stored was in a class of its own. But trying to access it from another class isn't working...

class Ipa{
var c : Settings;
function Ipa() {
}
}

class Settings {
var currSubs:Boolean;
function Settings (s:Boolean) {
currSubs = s;
}
function getSubsOn ():Boolean {
return currSubs;
}
function setSubsOn (s:Boolean):Boolean {
currSubs = s;
return currSubs;
}
}

then at root level:
var dpp : Ipa = new Ipa();
dpp.c.setSubtitlesOn(false);

and level 3:
_global.subtitles = _level0.dpp.c.getSubtitlesOn();

if ( _global.subtitles == false){
_level3.speech._visible = false;
};


And nothing happens...subtitles still showing...
Thanks in advance for help.

Don't know if you cut and pasted this on not but your method names don't match - 'function setSubsOn' but 'dpp.c.setSubtitlesOn(false)'

Every time you change the status of the subtitles with your approach above you're instantiating a new class which isn't the best way to work here if I understand correctly what you're trying to do and may be contributing to your problem.

Do you know about the 'singleton' design pattern? This would be a better approach and should solve your problem - there are many articles on the web that show you the approach and it's very simple to implement. What it does is give you a single instance of your class to work from that acts as a central repository for information like the state of your subtitles.

Thanks wangbar; I'll try going down that road...I did cut and paste it...thats why- was trying to keep different possible implementations separate...silly...Thanks again, silverswim.
