“NOTE: you instead of “substring(0,5)” you can use a shorthand of “substr(0,5)”.”

Hey, just wanted to point out something in case anyone was using this for a reference. substr() and substring() do two different things.

var str:String = “A test string”;
trace( str.substr( 2, 4 ) ); // traces “test”
trace( str.substring( 2, 4 ) ); // traces “tes”

===
“Thanks! have you seen a way to calculate how many rows a textfield has? im trying to reveal each line one at a time but cant seem to figure out how that could be done.”

You can use the numLines property on any TextField to find out how many lines of text it contains.

A better book to start with is Learning ActionScript 3.0 by Shupe and Rosser (O’Reilly). Awesome book for those getting their feet wet with AS3.

Hi Tim thanks for the comments, yeah well spotted it should be “charAt”. And the zip has been fixed.

What i would do is figure out how many are in a row (usually by counting em manualy) then use subString to extract up to that point from my string to send to the textfield/textarea.
I’ll try and work up an example later on for ya.

Hope this helps!

Also sorry trace(myString.charAr(9));

should be charAt?? The zip fla isnt available anymore? I’d love to see how you got the charAt method working i cant seem to.

Thanks! have you seen a way to calculate how many rows a textfield has? im trying to reveal each line one at a time but cant seem to figure out how that could be done.

Any help would be really helpful!
