I’ve got loads of stuff to post, but it needs a bit of cleaning up first (as most of it suffered late night last-minute hacks to accommodate client changes).

But anyway, here’s a simple little String function that removes any spaces from the start or end of a String, and removes any multiple spaces from within a String.

For example:

Input: "     Hello   world        "
Output: "Hello world" 

Here’s the code (Flash AS3):

function removeSpaces(string:String):String{

	//remove spaces at start
	while(string.substr(0,1) == " "){
		string = string.substring(1);
	}
	//remove multiple spaces in middle
	while(string.indexOf("  ") != -1){
		string = string.split("  ").join(" ");
	}
	while(string.substr(-1) == " "){
		string = string.substr(0,string.length-1);
	}
	return string;
}

Might save you five minutes!

Here’s another simple utility that came out of something old. It simply returns an array of consecutive integers, only in a random order, with no reptition. By default the smallest value is zero and the highest is the length of array requested – 1. However you can set the base value via an optional second argument.

A typical usage would be to trigger a number of animations in a random order.

Again, simple stuff but if it saves you 10 minutes then this post was worthwhile.

Usage:

import com.aderowbotham.utils.SequenceRandomiser;

//create a sequence of length 10
var mySequence:Array = SequenceRandomiser.createSequence(10);
trace(mySequence);    //e.g. 5,0,7,8,2,4,1,9,6,3

//create a sequence of length 10, from -5
mySequence = SequenceRandomiser.createSequence(10,-5);
trace(mySequence);    //e.g. -4,-5,0,-3,2,1,3,-2,4,-1

You may find a few handy bits and pieces in there. There’s not much at present but I reuse these classes a lot.
