Hi guys and girls,
Ive come across this before but i cant remeber for the life of me the solution :(. For some reason I cannot call methods in my prototype more than once via this.myMethod()…I have to store a reference to ‘this’ in the constructor using _global.ref=this; and then call my functions via ref.myFunction()…it’s real dumb. Although my proto sorta works…
Thanks in advance :love:
say wha? :huh:
Ok, sorry I should have simplified my explanation a bit. 
Essentially Sen Im trying to create a global Object which carries out repitive movie actions for my site.
The main function is loadContent which is used to load the various sections in my site. Probably the most complicated the typical scenario for this function is when a user clicks a menu item. It fades current movie to 0 alpha (using the handy $tweenManager class) unloads it (via unloadMovie), starts preloading the next, and finally on load complete fades up the newly loaded movie…
It works, well sort of… it seems since I only have 1 Object that if a user suddenly decides to press another menu item mid-load my function loadContent complely ignores it UNTIL it has completely finished loading previosuly selected movie…
**** I really need to post the code…its hard to put in words. Could you possibly skim through at least Sne and point me in the right direction…my architecture is poor as you can see :(.

Hello? Anybody please assist
Thanks in advance
Hmm well, ive narrowed it all down to 1 question.
How come when calling a supposedly ‘global’ function from another timeline (either external movie or parent object) this function which calls other ‘helper’ functions (within the same object as it) cannot use the helper functions via relative pathing??? i.e. this.helperFunction(vlaue1, vlaue2)
Short example…
Scenario: A menu item within menu_mc (path _root.menu_mc) is pressed
//_root.menu_mc
print_btn.onPress = function(){
Actions.printName();
}
//_root
_global.Actions = Object();
Actions.getName = function(person){
return person.name;
}
Actions.printName = function(){
trace(this.getName(person))
}
The above will not work!
instead to get it to work I must remove this and call the getName() function via Actions.getName()…that just doesnt semm right to me :h:
well I didnt read through all your code but above with printNane, there is no person to reference, no matter where you use it. the only place person exists is as an argument passed into getName within the getname function block. This is not at all accessible from printName in any way.
:)… Yeah Sen that was just an example…The person object doesnt exist, i was just
trying to illustrate my question. Lets say hypothetically person does exist…I still find
that printName will not work. a call to getName will returns undefined.
Do you understand my question now?
ooo… no I dont understand heh… because if person was a real reference with a name property, that should work fine :-/
Okie dokie, well I know it should work, but it doesnt if there are multiple calls.
Maybe bringing this closer to “home” you’ll catch on. Remember the XML menu u did Sen?
And then Lost went and reworked it into a another version with drop-downs and rotation arrows?
Well anyway, in your version you created an Object call Actions like so
//your actions handlers
Actions = Object();
Actions.message = function(msg){
message_txt.text=msg;
}
ring a bell!?
And within the menu, you have the items calling the various functions with onRelease events.
//some menu item onRelease
//this.action and this.variables being properties of the menu item mc pressed set with values from XML doc
Actions[this.actions[this.variables]
Now…going back to the Person example above, if you add the extra step of using a helper function
_global.Actions = Object();
//helper function
Actions.getName = function(person){
return person.name;
};
Actions.printName = fuction(){
//calling via relative pathing
trace(this.getName(person));
};
You will find that the first call to printName() will work, and from there on in
it won’t because for some reason getName() becomes undefined…you must use absolute pathing to get it to work
still not following you. Can you whip up a basic file demonstrating the problem? (with working references - or what you think should work ;))
btw, the menu with the rotating arrows both lost and I did together and the menu tutorial with the Actions object came after that 
OK, ill get right onto whipping up an example… Thanks
Oh yes thats right the credits ;)…Talking about Lost…havent seen him in a while
he’s lost. What more is there to say :lol:
Here it is Sen :)…All files included.
Goto line 113 of main.fla and you’ll see im calling by absolute path, now try relative and u will soon understand the source of my frustration :red:
wait, 113? Thats not basic :trout:
Heh the scripting is spaced out, its mostly yours anyway 
Please almighty Sen can you hlp me ?
