Trace command in FLash and general using a var 1

[fireburner69]

Ok I have this probleme which I can not understand fully!
I have a FLash movie! and I create some var!

For example!

for(x=0;x<10;x++) {
duplicateMovieCLip(_root.button,&quot;button&quot;+x,x);
}
all is smooth!
Inside the button Movie Clip I have a field named &quot;name&quot;.
I try to change the the text!
I used again to make it a loop like this

for(x=0;x<10;x++) {
&quot;_root.button&quot;+x+&quot;.name&quot; = &quot;Active&quot;;
}

So all the button will have the label active inside!
This is not possible!
an error comes up like this

&quot;Left side of assignment operator must be variable or property.
&quot;_root.button&quot;+x+&quot;.name&quot; = &quot;Active&quot;;
&quot;

So this is not possible!

And in the other hand!
I have this array!

_root.users
from 0 to 10
and when I trace one of the I use this method again!
for(x=0;x<10;x++) {
trace(_root.users.+x);

}

The answer to this is NaN
??? I do not understand what this is!
And whan i use &quot;_root.users.&quot;+x
this comes up _root.users.0 to 9 !!
But I want the var not the name!!
what can I do?

Assign values like this:

for(x=0;x<10;x++) {
    _root[&quot;button&quot;+x].name = &quot;Active&quot;;
}

... using '+' the way you were just creates strings not references.

Same for the array - you're just creating a string again. Try this instead:

for(x=0;x<10;x++) {
    trace(_root.users[x]);
}

So the tric here is! when I want to set a var! I will use this kind of type!~
_root.[&quot;name&quot;+x].name! ?

I can not understand the dif between! the string and the var!

I check it and It's work! Really thanx!

But Can you inlighten me! into this?
Please!
The string is just a name!
like
_root.button4.active that does not have a value inside!?
and var is a name which holds value inside? right?

If this is right! how can I understand when I create a string and not a var?

You need to tell Flash when something is just a value and when it is actually a path to something meaningful like a variable or movieclip. A string is not a name it is a value which can be assigned to something with a name.

Flash treats this as a string:

&quot;_root.button4.active&quot;

...but this as a variable:

_root.button4.active

So Flash will lookat this and think 'huh?':

&quot;myValue&quot;=24

...but will look at this:

myValue=24

...and think &quot;right, we're creating a variable called 'myValue' and assigning it the value of 24&quot;

question
if I type this
what will flash thing!
&quot;myvar&quot;+x = 24;
This will be a var or string?

 

[wangbar]

String.

But:

this['myVar'+x]=24

...is a variable.

You have to force Flash into evaluating things as variables in cases like this - let it know that the part in quotes is to be treated as a variable. You can do this as above by specifying the path the variable lives on (this or _root or whatever) or by using:

eval(&quot;myVar&quot;+x)=24

Hi fireburner69,

I really needed badly the same kind of functionality you wrote, and that is, creating dynamic buttons and with texts. Can you please send me a sample .fla file of this?

It will be easier for me to learn the .fla.

Thank you very much in advance.

Neil
