Hi

I’m trying to get the effect of letters cycling randomly until it gets to the correct letter and then stops…so you can have a word cycle randomly until it creates the word you want.

how can I achieve that in MX

There are 2 random letter cycling tutorials on this site…

you might want to see [http://www.kirupaforum.com/showthread.php?s=&threadid=11686](http://www.kirupaforum.com/showthread.php?s=&threadid=11686)

there is a function

Math.randomRange = function(min, max){  
return Math.floor(Math.random()\*(max-min+1)) + min;  
}

which can be used with the range of letters in char codes 97-122 (a-z) and be checked for correctness

simple example

```auto

Math.randomRange = function(min, max){
	return Math.floor(Math.random()*(max-min+1)) + min;
}
checkFor = "a";
this.onEnterFrame = function(){
	charValue = Math.randomRange(97,122);
	if (checkFor == String.fromCharCode(charValue)){
		trace("Found match: "+ checkFor +" and "+ String.fromCharCode(charValue) +" ("+ charValue +")")
	}
}

```

this doesnt stop, just traces a message, but you get the point
