I have recently been working on creating a game similar to the good ol' Asteroids game. So far, I have managed to create a very simple piece of code that rotates and moves my spacecraft according to the angle it is currently at. There are two problems with it, though:
1. I can't use two buttons at once--for example, to rotate and move forward. I'm sure there must be a better way to detect key presses. What's the best way to do it in AS3?
2. The way the whole thing works looks kind of jerky and stage. Another thing is, the spacecraft is constantly at an odd angle for no apparent reason.
Here it is ("sc" is my spacecraft movieclip):
var SC_speed:Number;
var SC_rotation:Number;
var SC_radians:Number;
SC_speed = SC_rotation = 0;
function keys(event:KeyboardEvent):void{

When I say two keyboard presses, I'm thinking about a situation where I would need to detect both. Not a shift this or alt that or control third. I'm talking about Down + A or 5 + T. For instance: Ryu has an overhead attack that is used when both Down + MP are pressed. If I were to create a game, with ActionScript 3.0, is there a way for me to detect that both buttons were pressed at the same time?

View 2 RepliesI have, lets say an arrow, it points up when you press w, left when a is pressed, down when s is pressed, and right when d is pressed. This is done through animations, and simple gotoAndStop commands. Anyway, Lets say that I want it to point North-east when I press D+W. whats the easiest way I can use to get it to detect Multiple key-presses. If any more explanation is needed I can easily explain further.

The problem is that the action listener seems never get called when I press any keys. the trace() is not called. But I tried to add a mouse listener just to test and it worked. So I guess its the Keyboard event listener class's problem? Everyone I see on the web uses stage.addEventListener(KeyboardEvent.KEY_DOWN, move) approach.

Detect a keyboard press in it?This is my [code]....
View 10 RepliesI'm using a keyboard event to detect when a key is pressed. This is what it looks like:
Code:
private function keyPressed(event:KeyboardEvent)
{
switch(event.keyCode)
{
case Keyboard.CONTROL:
ctrlHandle=true;
[Code]...
It's worked up until now. I know that all the keys except the last one work because they carry out their function and the trace on DOWN works. However, for the last one, I've tried W and ALTERNATE (and got errors) and ESCAPE and TAB (both not doing anything, not even returning the trace).
I was wondering, is it possible for a shockwave application to detect if a keystroke came for the keyboard, or from another application simulating a keystroke?
View 1 RepliesI came in to flash on ActionScript 3 and when I was starting out just over a year ago I realised how much of a bother finding keyCodes was and changing controls was just as long as had to look up the new one I wanted to use. My solution was to (eventually) write a class that handles all of my key presses and event listeners attached to that stuff. instead of using keyCodes, the functions use strings for their arguments making it easier to see what keys you want to do what. Initially the class only worked for letters and numbers but I managed to make it easily customisable and includes the arrow keys, numpad numbers, space, enter, shift and control keys.
The reason why I wrote this thread was because: I plan on making it a public class (available to anyone who wnats to use it) and b) to see if there were any specific functions that people think may be useful. So far there are the standard key-down and onRelease type functions as well as a function that only returns true once for the duration that a key is down - difference between pressing and holding.
AS3 script that detect if the mouse has no movement for 1min +no keyboard activity, it will call a function to change the frame in TimeLine.

View 2 RepliesI'm having problems referencing the stage from an external class. I've tried :
Code:
stage.addEventListener(MouseEvent.MOUSE_UP, onUp, false,0,true);
And also
Code:
MovieClip(parent).addEventListener(MouseEvent.MOUSE_DOWN, onDown, false,0,true);
But no luck. Can I not do this? I'm making a pencil class that I want to be able to reuse. I also tried "this" and while it didn't throw and error, it didn't work either.
When I debug this, it gives me an error saying that it cannot access the stage because it's a null property.

I'm trying to create an application with an extensive user interface. I've come pretty far and decided I wanted to really take advantage of the object oriented features that AS3 has to offer.
I've started off by created a few classes: User, Background and Main. Main is the document class of course. In the document class I have a function "resetStage" that clears the display list of all children. This is because I have many layers of images making up the UI and they all show up at startup unless I remove them. Besides I want to see where the stuff is positioned in the Authoring tool so I don't want to just create movieclips and then delete them.
My issue is with my Background class. Basically what I want to do is create a new DisplayObjectConatiner called bgContainer or something and then put all the background stuff in it. (The main background image and a status bar image). Then add the bgContainer and its children to the stage. This should all happen when the object is constructed.

public class Main extends MovieClip

How can I access objects and modify their property that is ALREADY placed on the stage using external classes (AS file)? I 'm a newbie of AS3 and followed some tutorials about AS3 not long ago. For I learned scripting in AS3 can be done using AS file rather than script on Timeline. But I have a question. How can I "find" and "modify"the objects on the stage, or inside a MovieClip , in AS3?
For example, I have a file call Stage004.fla which have no document class linkage. I place the MovieClip "StageMain" which links the Stage004.as on the stage. StageMain has a textfield in it named "textFieldStage001". The Stage004.as is ran using "Event.ADDED_TO_STAGE" since StageMain is on the stage. I create another AS file WindowRename , to test can I modify the text in "textFieldStage001".
Then the famous error #1109 occurred.
"1119: Access of possibly undefined property textFieldStage001 through a reference with static type Class."
ActionScript Code:
package {
import flash.display.Stage;
import flash.events.Event;
import flash.events.MouseEvent;
import flash.display.MovieClip;
public class Stage004 extends MovieClip{

I have a media player that I am codging together, one that will play either videos or MP3s depending on the variables it is passed. The video player part works fine. The MP3 player controls are all actual physical MCs on the stage; each one has its own AS class file as part of the package, but there is also a lot of AS that is happening in the main FLA as well. Messy, I know, but it mostly works great.
The MC on the stage in the main FLA is properly linked to the class file via Actionscript linkage, and the control itself works. However, I am trying to make some aspects of the control respond to variables that are set within the AS on the timeline of the main FLA, and I cannot seem to pass values to the control no matter what I do.

Still trying to wrap my brain about using classes in as3. I have my document class that calls another class that sets up buttons. I have the buttons working but I want them to play a movieclip on the stage when they are clicked. In AS2 I could just reference _root.mymc.play(); I am also having trouble setting up global variables which I think will have a similar solution. I think I read somewhere that I need to make a 'Globals' class inside my document class. Is this correct? I have tried doing that a few times but keep getting errors.

I have a dynamic textfield called neighName on my Flash stage. I also have a movieclip that I call a region on my stage. When I mouseover the region, I want a word to display in a little popup *and* I want some text to display in my textfield. I have an external .as file for handling the region. I can make the code "see" my region, but I can't seem to make it see my textfield, although no errors are being thrown.
