Actually , it’s not aproblem as much as it is lack of understanding ,
in one of the threads regarding letters following cursor there was this script :
Text = “Kirupa has the best site on the net!!!”;
letters = Text.split("");
letterformat = new TextFormat();
letterformat.font = “Verdana”;
letterformat.align = “center”;
letterformat.size = “10”;
spacing = 8;
speed = 3;
for (var LTR = 0; LTR<letters.length; LTR++) {
mc = _root.createEmptyMovieClip(LTR+“l”, LTR);
mc.createTextField(letters[LTR]+“t”, LTR, LTR*spacing, 10, 20, 20);
with (mc[letters[LTR]+“t”]) {
text = letters[LTR];
setTextFormat(letterformat);
selectable = false;
}
if (LTR) {
mc.prevClip = _root[(LTR-1)+“l”];
mc.onEnterFrame = function() {
this._x += (this.prevClip._x-this._x+5)/speed;
this._y += (this.prevClip._y-this._y)/speed;
};
} else {
mc.onEnterFrame = function() {
this._x += (_root._xmouse-this._x+10)/speed;
this._y += (_root._ymouse-this._y)/speed;
};
}
}
and my question is
what does if (LTR) means ?? ? doesn’t “if” need acondition , or does it mean only the existence of (LTR) , one more thing , I noticed that if i’d delete the “_root” used in the last two lines the script would still work … so why did we use them in the first place ? ??
