Hi

I’m trying to get the bt text over effect here:

I’ve set-up a simple mc button and applied the text effect script (below) to the over state in the mc - But I can’t get it 2 work.

Grateful for any input going - .fla attached

Thanx

textEffectF(yourTF);

Array.prototype.shuffle = function() {
	for (var ivar = this.length-1; ivar>=0; ivar--) {
		var p = random(ivar);
		var t = this[ivar];
		this[ivar] = this[p];
		this[p] = t;
	}
};
a = "abcdefghijklmnopqrstuvwxyz 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ!@#$%^&*()-_+=[]{};\':\"<>?\\,./";
A = a.split("");
B = A.concat();
B.shuffle();
function textEffectF(tf) {
	var origS = tf.text;
	cnt = -1;
	changeI = setInterval(changeF, 1, tf, 0, origS);
}
function changeF(tf, ind, s) {
	cnt++;
	if (cnt>=A.length) {
		cnt = 0;
	}
	for (var j = ind; j<tf.text.length; j++) {
		if (j>ind) {
			tf.text = tf.text.substring(0, j)+B[(cnt+j)%A.length]+tf.text.substring(j, s.length-1);
		} else {
			tf.text = tf.text.substring(0, j)+A[cnt]+tf.text.substring(j, s.length-1);
			if (s.charAt(j) == A[cnt]) {
				clearInterval(changeI);
				ind++;
				if (ind<s.length) {
					changeI = setInterval(changeF, 1, tf, ind, s);
				}
			}
		}
	}
	updateAfterEvent();
