ActionScript ReferenceError: Error #1056

ReferenceError: Error #1056: Cannot create property _x on flash.display.Sprite

ActionScript 3 Error #1056 Description:
AS3 error 1056 appears when you have improperly referenced a property of an object. This will happen when you misspell something or when you reference variables in the AS2 fashion with a leading underscore ( _ ). AS3 error 1056 is actually pretty nice to work with because it tells you exactly what variable didn't work and it tells you which object it didn't work on.

Flash / Flex Error 1056 Fix:
Simply spell the property correctly or make sure that you are using AS3 Syntax instead of AS2.

Bad Code 1:

var s = new Sprite();
s._x = 100;

Good Code 1:

var s = new Sprite();
s.x = 100;

Bad Code 2:

var t = new Timer(1000, 4);
t.dela = 500;

Good Code 2:

var t = new Timer(1000, 4);
t.delay = 500;

This should help you resolve Flex / Flash Error #1056

Thanks and as always Happy Flashing

Related ActionScript Error(s):
Flash / Flex Error 1119 - You will get AS3 Error 1056 instead of 1119 if you don't properly type your object before referencing a property on it. For example var s:Sprite = new Sprite(); s._x = 10; will give error 1119 but var s = new Sprite(); s._x = 10; will give Error 1056.
Flash / Flex Error 1151
Flash / Flex Error 1069 - This is the error you will get if you try and call a method with a misspelled name in the same way as calling a property with a misspelled name.
