LoadVariables from text file into Actionscript.

[Andy K]

Im loading variables in from a text file which looks like this...

variable1=hello&bigimage=main-graphic.jpg&title01=rebrand


This works fine, I can add a variable to a dynamic text field by adding

_root.variable1 ...... in the textfields' Properties Var: field.


However I want to use variables in ActionScript as a normal variable. i have tried this...

Code: Select all

 
loadVariablesNum("title.txt", 0);
 
myVar = _root.variable1;
 
trace(myVar);

BUT it returns as 'undefined' ............ So, how can I get the variables into ActionScript usage?

I write a tutorial about loading links from an external text file :

maybe this can help you
If it didnt please attach your fla file...

Tried the method in your Tutorial and it gave the same outcome.

I have attached a flash movie with both methods, and text.txt file containing the variables.

trace(_root.varTwo) comes back as undefined, but the value appears in a dynamic text field, therefore the variables are loading in ok, just not usable in code.

I want to use the variables in actionscript because..... you may notice varTwo=filename.jpg ........ I want to reference filenames in the actionscript so i can load external images dynamically without hardcoding them into flash.

The reason for that is the variable you are calling is inside function scope and available only in function scope, not outside that, so you get undefined when you call it

So do I need to load the variables and call them from inside the same function?

It traces undefined because trace will run before the function is called, one way is to add another frame to your timeline and there trace your variable and you will get the result.
