var t:TextField = new TextField();

t.autoSize = TextFieldAutoSize.LEFT;
t.textColor = int(Math.random() * 0xFFFFFF);

Sometimes you need to do something to a TextField one letter at a time. One way to do this is to create a separate TextField for each letter and position them based on the TextLineMetrics object. This snippet creates textFields for a string and colors each TextField randomly.
This post reminded me of splittextfield at greensock: http://www.greensock.com/splittextfield/
But also useful to not use a full library when performing text operations like yours above.
Does TextLineMetrics retain the ‘virtual’ letter spacing when placing TextFields side-by-side? For example, if I format a TextField via styleSheet, or via TextFormat, and if I copy from that textField letter by letter and place each letter within it’s own textField side by side, are those letter spacing numerics captured / retained when using TextLineMetrics? Sorry for the long questions.
@Jeff that looks cool.
@Lex I’m not really sure … you should try and create a test to see if it works or not – because off the top of my head, I’m not really sure.
This is an alternative (note: I know yours is an example of what you can do with the metrics and note just about the example :-)) and should be a lot faster.
var word:String=”TextLineMetrics are useful”;
var textformat:TextFormat=new TextFormat(“Arial”,40);
var t:TextField = new TextField();
t.autoSize=TextFieldAutoSize.LEFT;
t.text = word;
addChild(t);
for (var i:int = 0; i
Really cool. Thanks for digging the new as3 apis. Now I will make my little text effect engine.
