ActionScript Error #1024

Posted in Error, Error, errors, Flash, Flex at 11:05 pm by Curtis J. Morley

ActionScript Error #1024: Overriding a function that is not marked for override.

AS3 error 1024 means that Flash or Flex already has a function by that name.

To solve Flex/Flash Error 1024 all you need to do is either correctly name the function something besides a reserved function in Flex/Flash or properly override the function. The example below shows how to solve issue number one. Notice that the good code solves Error 1024 because it doesn't use the same name as a function that already exists in ActionScript.

Bad Code 1:

function nextFrame (e:MouseEvent):void

Good Code 1:

function onNextFrame (e:MouseEvent):void

This should help you resolve Flash / Flex Error #1024

Thanks and as always Happy Flashing

    You may also get this error if you are using inheritance in AS3 by re-implementing one of the interfaces your base class, a class you extend, also implements. To solve this just use the keyword override in the method declaration.
