If I make multiple draw calls for various Program3D instances, is there a way that I can reset or nullify the constants if I'm no longer using them in the next following Program3D assignment?
Is it even necessary that I do something like this?
//Nullify 'vc0' in the vertex shader:
context3D.setProgramConstantsFromVector("vertex", 0, null);
I've mostly seen examples where a Matrix3D object is passed as a vertex constant register in AS3 to the Context3D object. But never seen a matrix in any other types of registers (temporary or attribute).Would there be any way to copy a Matrix vertex constant to a temporary register, and then manipulate individual fields of that Matrix temporary register (ex:for the rotation), with other supplied values (vertex attributes or other constants)
View 2 RepliesI'm trying to understand molehill and would like to multiple a vertex by two matrices, say:
output = theVertex * scaleMatrix * rotationMatrix
Im guessing my vertex shader would look something like:
"m44 vt0, va0, vc0
" +
"mul op, vt0, vc1
";
And i would set the matrices with
context3d.setProgramConstantsFromMatrix(Context3DProgramType.VERTEX, 0, scaleMatrix);
context3d.setProgramConstantsFromMatrix(Context3DProgramType.VERTEX, 1, rotationMatrix);
But its not working.Im aware that i could multiple the matrix before putting on the shader, but i am trying to understand AGAL.
Using the Molehill with Flash I wish to create a vertiex shader, to have one mesh transform into another, I have seen that it is possible with Flare, However I am unsure if that was using Stage3D, Can anyone give me any pointers in the use of shaders in AGAL as to how this might be done.

I've read that the cause of that was supposed to be integration of Flex application with browser navigation, so I disabled it at the Flex compiler properties screen, however it didn't fix anything.

Is there a way to render multiple vertex buffers in AS3?Right now I have two objects which I want to render, but the only way I can think to do it is to concatenate the raw vertex data (of both objects) and then set that (concatenated) vector as the vertex buffer.I would prefer to do this as 2 separate vertex buffers, but I don't know how to render from more than one vertex buffer.
View 1 RepliesJust new in forum and just new in as3 programming. All i want to do is to make some physics simulations (i'm physics teacher...). So i made my first sim with the following code, just to simulate a simple motion with constant velocity. It works ok, except the part i need to reset the display by the means to start the motion all over again (reset button). Then the motion starts but the traces of the previous motion remains on stage. I tried the null command (sp=null) but the sim could not start again because the sp nedded to be non-null...

I have an issue with adding a reset button to my drag and drop movie clips.The problem is, if a student drags a movie clip to a wrong location on the SWF file I want them to be able to hit a reset button that would take them the same SWF that they opened and what would showup would a clear page for them to restart their drag and drop exercise.I know how to make the button for this just want the proper action script to be able for user to start over with no movie clip symbols on the page.
View 3 RepliesWhat is the most proper way to store "global" constants for a flash app:
a static data class
a dynamic data class
a dynamic data class via getter/setter
We have a project that has been built in Flash and as3. It is a video player of sorts that we want to fully customize. We have different images and color schemes that we want to be able to change very quickly. Right now we have config constants that we turn on and off for different schemes. And in the code there is a massive amount of different spots where the images and such are changed.When we create a new color scheme or whatever, we need to create a new config. Then we have to go through all of the code and put it in correctly.Basically any suggestions for how we can take the current flash project (maybe flex?) and make it customizable a lot quicker.
View 1 RepliesI would have expected, given the way Adobe seems to do things, that you could reference some of the non-ASCII keycodes using a static constant, for example KeyCode.UP_KEY. Am I dreaming? Or do you just assume 38 will be the up key in perpetuity..?
View 1 RepliesI have a class that holds some constants and will receive an object literal (associative array) with some data like this:
var ConfigObj:Config = new Config({
"Some" : 10,
"Other" : 3,
"Another" : 5
});
The class looks like this:
public dynamic class Config
{
static public const SomeProperty:String = "Some";[code].....
Flash UI Components have many different styles to set, which require passing a string name to the setter method.while this certainly is not challenging, the use of a constants class would be beneficial but i can't find one.is there no constants class available with all of the possible style settings?

View 3 RepliesIs there a way to compile SWC files in different targets (Debug vs. Release) similarly how you can compile a SWF file with the AS3 Conditional Compiler constants?
This link shows how SWF files can be compiled with predefined compiler constants:[URL]..
But I need to know how to achieve this with SWC files instead.
Note: I'm using FlashDevelop (Windows 7) to create the SWC (if that's any help to refine the answer).
I always assumed constants to be good, obedient variables that are only set once, and thereafter never change.They are reliable and... well... constant. However, the term "compile-time constant" seems to pop up quite a bit.Does this mean that rather than treat references to the constant as references to a variable, Flash goes in (at least for numbers, booleans, and strings) and during the compiling replaces all the references to the constant variable with those actual values? For instance, this line during "edit mode":
stage.addEventListener(MouseEvent.CLICK, onClick);
during compile time, the Flash FIRST replaces it to this:
stage.addEventListener("click", onClick);
and AFTER that finishes the compiling into bytecode?
This method would be a little faster since it doesn't need to access the constant as a variable, but instead has the actual value, which is a fraction of a second saved, but it can add up in the long run.Is this what happens or am I way off? Why otherwise would there be the term "Compile-time constant", and what does that refer to?
Just wondering if there is a way to read class static constants from a SWF file server side. I have found things like getimagesize() but it doesn't have all these details. I guess that means I need a partial decompiler.Specifically, I have this class in my Flex project:
package
{
public class AppVersion
[code].......
How can I have a constant in a Flex application which I could apply at several places in a Flex CSS file? For example I may have a background color which is the same in several UI components and then I would like to have this color set in only one place and reused in all style clauses. Something like ...
public static const myColor = "#00FF00"...
component1 {
backgroundColor: myColor
}
component2 {
backgroundColor: myColor
}
Basically I want to call a const by a int. Here is the code I have so far...
public static const _100:String = "name=lion legs*type=legs";
public static const _101:String = "name=lion tail*type=tail";
public static const _200:String = "name=tiger legs*type=legs";
///more lines going down with the number on the far left being the main differentiating factor
public static function getByName(name:int):String {
[Code] .....
Is there a better way out there to call the constants by an outside int without having a switch function handle the logic?
i can write constants in two ways:
MouseEvent.CLICK - "click"
MouseEvent.ROLL_OVER - "rollOver"
TextFieldAutoAlign.LEFT - "left"
etc.Is there any difference between the two ways of writing?
Despite if it is good practice or not, I read here that you can have package variables (or constants), so I tried this:

I want to create a function pointer object:
private var func:Object = { Class.Constant: function };
What is the clean way of doing this? I did the above and got
Error: Syntax error: expecting colon before dot.
And I'm not even sure that's right. The goal is that I can just do
func[ Constants ]();
I just found out that it is executed like a normal variable at runtime. Typically constants are supposed to be 'inlined'........ so when you write this:
ActionScript Code:
const SPEED:int = 5;
o.x += SPEED;
...you should get this in the SWF:
ActionScript Code:
o.x += 5;
...but when I decompile my SWF I get this:
ActionScript Code:
const SPEED:int = 5;
o.x += SPEED;
Is there a way to force the Flex compiler to inline constants in AS3?
How can I get the ord values of certain keys. Say if I want a function to run when the left arrow key is pressed or right arrow key. Or is there a constants list?

View 14 RepliesI am working on a Flash site template for which I am implementing the possibility for the users to change the theme dynamically while the site is opened.Basically, the site will have a few themes available and when the user selects a new theme, all of the site objects will change their properties (colors, alpha, fonts, etc) to fit the new theme.
And my questions is what is the best approach to sending the theme information to all of the objects in the site.I was thinking of making a static class called "Theme" and when the objects need a property, they will call a static getter of the Theme class that will return the appropriate property value for the object.But, from my understanding, static properties are quite slow and seeing that I may need quite a lot of them, maybe more that 100 for the whole site, will this approach be too slow ?
