Saving data from DDBB into AS class

0
votes

i am trying to make a "game" in Flex similar to Shake&Fidget. I'm saving all the user data in a mysql database and I retrieve the data using ZendFramework (PHP). I thought of saving all the user and character info I'm going to need into am AS class so I can use that data in every view.

The data recived from the database is correct. I was able to load it in my app labbels but everytime i changed views it had to ask it again, so i thought of making this classes in order to just ask once for the information.

I'll post here the files so it's all more clear.

ViewNavigatorAplication.mxml

<s:ViewNavigatorApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
                        xmlns:s="library://ns.adobe.com/flex/spark"
                        firstView="views.RotrHomeView"
                        persistNavigatorState="true">
<fx:Script>
    <![CDATA[
        import flash.net.registerClassAlias;

        import valueObjects.Character;

        registerClassAlias("Character", valueObjects.Character);
    ]]>
</fx:Script>

The first View goes to the login screen, it works OK. So i'll go to the view that loads and "tries" to show the character data.

char_panel.mxml

<s:View xmlns:fx="http://ns.adobe.com/mxml/2009"

If you are still here you have all my respect :D When i try it out, i get the following error. I've tried in char_panel.mxml using Character::modStats(...) instead of data.modStats i'll put the error log under this one.

Thanks in advance to anyone that get so far in this help cry :D i'd apreciate any sugestions that you can make.

ok so the reason it doesn't work with data is that event though you said 

data = new Character();

data is still actually an object (that now looks like a character). to make it work

var myChar:Character = Character(data); // cast it to a Character and it now knows the method
myChar.modStats()

the reason the other call didn't work is the way you called it:

Character::modStats(...)

This say look for a method called modStats in the namespace Character. Instead call this

character.modStats()

and it will work.

You Sir are my personal Hero :D, i've just tried it and it shows the data.

I changed the constructor for the character in Character.AS like this:

public function Character(obj:Object)
    {
        this._stats = new FinalStats();
        this._gear = new GearList();
    }

I'm not entirely sure if this is correct, but as you mentioned in your answer: 

var myChar:Character = Character(data);

I supose i'll have to use that data object to initialice myChar...am i right? Well, later when i have the time i'll try to add new views and buttons to go through views and see if the data is there :D
