Hi, I found this awesome text effect class. Can anyone give me any ideas on how I would go about making this work multi-line? I’d also like it to reverse and erase itself on call. Any tips?


class com.texts.effects.TextAdd {
    public static function makeText(textBox:TextField, theText:String, myInterval:Number):Void {

        if (theText == undefined) theText = textBox.htmlText;
        
        var textLength:Number = theText.length;
        var letterCount1:Number = 0;
        var letterCount2:Number = 0;
        textBox.html = true;
                
        var textInt:Number = setInterval(makeTheText, myInterval);
    
        function makeTheText():Void {
            
            if ( letterCount1 != textLength+1 ) {  // MAKE RANDOM TEXT
                
                var randomChar:String = String.fromCharCode (150 + Math.round(Math.random() * 90)); // set random character
                                
                textBox.htmlText += randomChar; // add random character

                ++letterCount1; // increase counting variable by 1
                
            } else { // WRITE OUT YOUR INPUTTED TEXT
            
                var oldTextBoxText = textBox.text;
                
                var oldTextSplit:String = oldTextBoxText.substr(letterCount2, textLength-letterCount2+1) // split old character from counting variable to the length of the text string
                var textSplit:String = theText.substr(0, letterCount2) // split new text string from 0 to counting variable

                textBox.htmlText = "</font><font color=\"#999999\">"+textSplit+"/</font>"+oldTextSplit; // put splitted texts together
                
                if ( letterCount2 == textLength+1 ) {
                    textBox.htmlText = "</font><font color=\"#666666\">"+theText+"</font>";
                    clearInterval(textInt);
                }
                
                ++letterCount2;
            }
        }
    }
}
