Subject: Re: [Flashcoders] AS3 - Problem with first item in Array
Hi, SJM,
Hypothesis: Don't know if this is different for AS3 (couldn't find the
appropriate documentation in a quick search) but I got into the habit of
avoiding assigning values for declared variables in the class body unless
they are static variables. My recommendation would be declare variables like
your arrays in the class body:
public var containerX:Number;
And then initialize them in your mainClass() function
containerX = (stage.stageWidth / 5);
Otherwise you may get unpredictable results based on what's in memory at the
time.
