A "Find and Replace" method is always handy when trying to avoid repetition in code (especially when replacing variables in XML Strings) and so here's a quick script everyone should know:
public static function replaceWord (searchString:String, find:String, replace:String) : String
{
var wordLength = searchString.length;
var result:String = '';
for (var i = 0; i < wordLength; i++) {
if (searchString.substr (i, find.length) == find) {
result = searchString.substr (0, i) +
replace +
searchString.substr (i + find.length, wordLength);
}
}
if (result == '') result = searchString; // didn't replace anything
return result;
}
I've recently been working on a physics/trigonometry project at home using Processing and memo's amazing MSARemote. In short, I realized I haven't posted anything on Tomorrow Evening in ages, I have a lot of cool things up my sleeve right now, just trying to find time to get all these ideas out. I'll be taking all of Thanksgiving week off to take a break from work and do some fun experiments. If I weren't a web developer I'd turn my internet off for a few weeks, I keep finding such great developers/art online that I start something new every other day and never finish what I was working on the day before! That needs to end soon :P. I know I said I was doing a Processing experiment and this code is in AS3 but I have a good reason why! My wordpress doesn't know how to format processing code and since it's only a few lines, I converted it to AS3.
function findDistance(x1:Number, y1:Number, x2:Number, y2:Number) : Number{
var xd:Number = x1 - x2;
var yd:Number = y1 - y2;
var td:Number = Math.sqrt(xd * xd + yd * yd);
return td;
}
function findAngle(x1:Number, y1:Number, x2:Number, y2:Number) : Number{
var xd:Number = x1 - x2;
var yd:Number = y1 - y2;
var t:Number = Math.atan2(yd,xd);
var a:Number = 180 + (-(180 * t) / Math.PI);
return a;
}
