    copied!<p>Pretty new flixel/AS3 user here, though not entirely new to coding. Anyways, the error is pretty straightforward in it's cause, but not it's solution. </p> <p>"Error: Access of possibly undefined property through a reference with static type org.flixel:FlxSprite." </p> <p>It gets thrown 6 times, twice with the property scrap.selected and four times with scrap.distanceToMouse - I've marked each line that throws an error with comments. </p> <p>I've searched throughout the web and StackOverflow specifically. It looks like a pretty common problem, but I haven't been able to apply any solutions to my specific situation. Anyways, Here's the relevant code... </p> <p>ScrapManager.as </p> <pre><code> if (FlxG.mouse.pressed) { var ClosestDistance:int = 500; for each (var scrap:FlxSprite in this) { scrap.selected = false; //error here!~ var dx:int = scrap.x - FlxG.mouse.screenX; var dy:int = scrap.y - FlxG.mouse.screenY; scrap.distanceToMouse = (dx * dx) + (dy * dy); //error here!~ if (scrap.distanceToMouse &lt; ClosestDistance) //error here!~ { ClosestDistance = scrap.distanceToMouse; //error here!~ } } for each (var scrap:FlxSprite in this) { if (scrap.distanceToMouse == ClosestDistance) //error here!~ { scrap.selected = true; //error here!~ } } } </code></pre> <p>Scrap.as</p> <pre><code>package { //import stuff... public class Scrap extends FlxExtendedSprite { public var selected:Boolean = false; public var distanceToMouse:int; //and more stuff... </code></pre> <p>I think (hope) that's all that's needed to solve this, but I'll be happy to provide more if needed. Thanks for reading. :D </p>
