[osflash] Am I overlooking any crucial tools?

[izak marais]

Ok, thanks for the help, I will post language questions elsewhere in future. For interest sake (from the Actionscript 3 programming guide) :

"To ensure that your program responds to events, you must add event listeners, either to the event target or to any display list object that is part of an event object’s event flow."

which explains why your examples worked and mine didn't.

Yes, new thread would be better. And also probably the wrong group, as there is also flashcoders, flexcoders, etc.

Simple (not best?) answer is to add listeners to the full app, such as:

this.parent.addEventListener(KeyboardEvent.KEY_DOWN, onKeyDown)     
this.parent.addEventListener(MouseEvent.MOUSE_DOWN, onMouseDown)   

And you must first click into the app. Your code would work, if you clicked the text, as the parent Sprite only stretched to contain the TextField.

I normally do flex projects, so am only guessing in AS project, but this change did work for me.

Hi there,

I don't know if it might be better to start a new thread, but this question is related to porting my code from AS2 to AS3 as suggested in this thread. Can anyone please help? It is (I think) a simple problem.

I can't get keyboard and mouse events to function properly. KeyBoard events (KEY_DOWN) don't seem to have any effect while mouse events only work occasionally. Below  is a minimal example. When I run it and press keys and the mouse (while flash has focus), I occasionaly  see "onMouseDown():called", although  it is very random, the number of traces is much fewer than the amount of actual mouse presses and generelly require at least 2 seconds between presses to register (although sometimes it does not work even when I wait longer). Key presses do not result in any traced output. 

(I did check wheter the problem perhaps lies with "trace()" by doing someting in the event-functions, but this is not the case).

Please help somebody! 
Thanks
Izak

@Daren.. Thanks, but we use our own logging system that has different output options.

@Niels: Thanks for clearing up my misunderstanding. 
@Daren: With AS2 I had been using a similar custom class to write to the top-level of the movie; based on that I had completely the wrong idea of what trace() should do. I'll try using trace() and 'tail' to output to shell and file; it seems useful.

Sorry for the confusion; I just meant as a way to identify that you are
using the debug player. Like you Debugger doesn't actually do anything
for me.

BTW, I have a Logger class that has an option to write to the top-level
of the movie, and hide/show with the D key. It is open source (as soon
as I get around to doing a release); if you want a copy before then let
me know.
