own code, in addition to those errors trapped by a Flash runtime. You can create a subclass of the Error class to track the new error data type in as3 error 1046 try..catch blocks. To provide unique error display capabilities for errors generated by your application. For example, you can create a new toString() method that formats your error messages in a certain way. You can also define a lookupErrorString() method that takes an error code and retrieves the proper message based on the user’s language preference. A specialized as3 error 1119 error class must extend the core ActionScript Error class. Here is an example of a specialized AppError class that extends the Error class: public class AppError extends Error { public function AppError(message:String, errorID:int) { super(message, errorID); } } The following shows an example of using AppError in your project: try { throw new AppError("Encountered Custom AppError", 29); } catch (error:AppError) { trace(error.errorID + ": " + error.message) } Note: If you want to override the Error.toString() method in your subclass, give it one ...(rest) parameter. The ECMAScript language specification on which ActionScript 3.0 is based defines the Error.toString() method that way, and ActionScript 3.0 defines it the same way for backward compatibility. Therefore, when you override the Error.toString() method, match the parameters exactly. You do not want to pass any parameters to your toString() method at runtime, because those parameters are ignored. Twitter™ and Facebook posts are not covered under the terms of Creative Commons.

Because it's user code, it may throw exceptions. Unfortunately, I can't seem to catch the exceptions. This code doesn't work: this._loader = new Loader(); this._loader.uncaughtErrorEvents.addEventListener(UncaughtErrorEvent.UNCAUGHT_ERROR, onUncaughtError); this._loader.contentLoaderInfo.addEventListener(Event.COMPLETE, swfCompleteHandler); this._loader.loadBytes(swfByteArray, loaderContext); However, the debug player shows this in the unhandled exception dialog: [Fault] exception, information=Error: Test error message at global$init() [User_Code:3] How do I catch an exception in global$init() of a loaded SWF? I've tried adding UNCAUGHT_ERROR event listeners to every loader and loaderInfo I can find... but none of them trigger when the exception is thrown from the loaded SWF's global$init(). Thanks in advance. actionscript-3 exception-handling share|improve this question asked Jun 19 '14 at 4:42 DoomGoober 322117 Is your onUncaughtError function executed? –net.uk.sweet Jun 23 '14 at 13:02 1 Unfortunately, onUncaughtError function does not execute when loading a SWF that throws in its global$init. onUncaughtError does execute if the exception is thrown anywhere else. Thanks. –DoomGoober Jun 24 '14 at 3:58 Have you tried putting the loadBytes() line of code inside a try...catch? –C. Parcell Aug 22 '14 at 15:17 Did you eventually null'ed the loader in the swfCompleteHandler functio
