scene.nodes.getByName("...").transform in animation U3D annotation

Hello

I use scene.nodes.getByName("...").transform to extract a part of the world transformation matrix (Matrix4x4). When I run the animation of a U3D file annotation, this part is moving with respect to the axis of origin and I guess its matrix must change. However, I get the same values as before. Y at - it won't read the actual position of a party in an animated 3D annotation?

Thank you

If a node is in motion, but the matrix .transform isn't changing, then it rolls by a mobile node - so there is no movement in the local coordinate system (i.e. what .transform stores). You will need to level up and inspect the node which is the engine that is the movement, whatever.

How to have 2 functions enter_frame that passes through one? I have a scene where I have an animated moving on stage film and I also want to have a custom cursor also go on stage on the same chassis.

var mc_Dog1:WagDog = new WagDog();
addChild (mc_Dog1);
mc_Dog1.x = 50; I have this in my event ENTER_FRAME handler)
mc_Dog1.y = 20;
mc_Dog1.width = 140;
mc_Dog1.height = 120;
addEventListener (Event.ENTER_FRAME, dogMove);
function dogMove(event:Event):void
{
If (mc_Dog1.x < (stage.stageWidth + 25)) {}
mc_Dog1.x += 2;
myCursor.mouseEnabled = false; The commented custom cursor is also a clip, I need this format as in my animated quiz that I also use to drag and drop)
Mouse.Hide ();
myCursor.x = root.mouseX;
myCursor.y = root.mouseY;
} else {}
mc_Dog1.x = - 25;
}
}

You can use one or two enterframe listeners. for example,.

(a) 1 earpiece

this.addEventListener (Event.ENTER_FRAME, f)

function f(e:Event):void {}

F1();

F2();

}

(b) 2 headphones

this.addEventListener (Event.ENTER_FRAME, f1);

this.addEventListener (Event.ENTER_FRAME, f2)

Transform an animation frame-by-frame in a bearing

So I was find a lot and it has been so much help. I'm taking a 40 image animation and make a button bearing and I do not understand how with the new cc flash. I create a button but it doesn't work and I really don't want to have to support on adobe that I had to do that cost me way to much time. If I can cut the middlemen, I just do it here in adobe flash.

Would you know how to do with an old version of Flash? Normally for a scenario as a button animation, you will need to use a movieclip instead of a button symbol. You must have a stop() in his timeline on the first image, and when a rollover event occurs you'd say animation play(). When you deploy tell you her either to gotoAndStop (1) or let you play thru so that it completes the animation and returns to stop at frame 1.

getByName & question randomness (Root.204ba79a45804da02860)

Hello
I have a PRC file in my PDF.
In the tree of Acrobat, it displays the names of the objects correctly.
If I have a list of people using JavaScript in the console, then he gives me the name over a load of characters. This makes it impossible to reference the knots or cracks on the stage.
This is the javascript code...
for (var i = 0; i < scene.nodes.count; i ++)
{
Console.println (Scene.Nodes.getByIndex (i). (Name)
}
And this is the output
Root.204ba79a45804da02860
Camera.204ba79a45804da02808
Sphere.204ba79a45804da02830

I use Adobe Acrobat Pro DC version 15.016.20041.55549.
Does anyone know what are these extra characters?
It makes it impossible to use getByName since then because of these random characters.
IE scene.nodes.getByName ("Sphere"); does not return a valid node.
Thank you
Kent

I handled this in the past by creating a function that runs through the knots looking for the substring until the period and then returning this node. It can be slow on large models, but it does not work.

No, you must do it yourself.

How can I convert my animated film in a video work that can be used with a new scene?

Hi all
First of all, I'M a TOTAL FLASH NOOB. I want to preface this and make new incredibly clear how it is for me. LITERALLY, I started using flash this morning; It is precisely the way the news I am.
That being said, I will do my best to explain what I want to do.
I've created an animation of a spider moving her legs back. I want to be able to combine all the layers in 1 simple animation that can be imported into new scenes flash with animation exactly how it goes. I figured out how to convert a symbol of the entire animation, AND I figured out how to import the clip to the library. However, it is my problem. When I open a new scene flash and import my animated movie, I play and there is no nothing. It's just the static image of the spider, I created with no movement.
I spent the last two hours trying to figure out (and do my own research) what I did or did not to get to this point. I'd be willing to bet that I'll just on the wrong process and I am overlooking a facet of the program.
Any idea to fix my ignorance is greatly appreciated.
(P.S. Hell, I don't even know if I use the correct terminology as far as I know I'm confusing anyone who took the time to look at my question. If I use incorrect terminology please correct me to avoid a future hang ups. (Thank you.)

I don't think you mentioned this aspect, or I just didn't read that way. If your movieclip contains only a picture, then you did not create correctly. It should include all frames and layers that shows your first screenshot (which is what I thought you showed because that's what I asked).

Here's what you need to do. Start by selecting all images and layers of this chronology that is supposed to be your animation.

Then right-click the selection and choose copy image.

NEX, create a new movieclip with Insert-> new symbol symbol-> MovieClip

Then select the one and only key frames of the timeline within this new movieclip, right-click and choose Paste images. This should now be a successfully created version of animation that you can place on a timeline.

Interesting things, however, strangers? StackPane, animations and filters.

CHANGE (17/01/2014):

As suggested by jsmith , I changed this thread so we could treat the on only one thing. Other issues that existed here before I put each in its own separate discussion. I hope that now we can deal with it properly, so start New:

For the first test case, I tried to create a program that has some controls and I put a animated background behind her done with nodes in transition. With such a test, I received the following Visual result:

I think that my tree of nodes is structured as follows :

http://S27.postimg.org/pjpvnlywz/rvore_de_n_s.jpg

I also have tried to change the root of my scene graph to StackPane. Unfortunately, the result was weird. Despite my interface controls went to the middle of the window (which is what I wanted), the bottom began to to animate in a totally weird way. I don't know what else to do on this subject. , It would be strange If this type of feature is not exist in JavaFX, because I could easily do this kind of thing to the Swing Framework library and timming. So far, I still can't understand how I could get around this problem. As a user of JavaFX, I think that it would be more interesting if the JavaFX developers would put more cool similar things to present in the documentation us. Well... If someone can help me Iwill be really grateful. I don't know a lot of people peut Can also take advantage of this too.

Thank you for your attention and patience in any case.

Editada por Mensagem: Loa

It seems to me that I finally got the result I wanted, thanks to God and to you for this. I'd love to share with the community here:

Using StackPane as root, it seemed to me that I was not getting the desired result. As you say, make use of the group for circles, causes odd effect I spoke. That's because you showed me in the JavaFX API, group is committed to the size of its child nodes. As in this type of animation background changes its size in transition (and because it's in a layout that centralizes things like StackPane), it seems that the circles are not calm and move every time they becoming or shrinkage. Using StackPane as one parent node to the circles, they are all mainly in the center of the Panel, as it is one of the goals of StackPane. As I intend to change their positions, I used the following code block so that it is possible (in the case where triggered when the button is clicked):

circle.setTranslateX(Math.random() * cenario.getWidth());
circle.setTranslateY(Math.random() * cenario.getHeight());

He was supposed to distribute the circles in the background of the window. However, it was not quite what happened. This that this resulted in circles in the background OF THE CENTER OF THE BACKGROUND, not distributing from the upper left, as initially planned by me. This means that the starting position in the center of a StackPane node leaves, that is to say StackPane not only centralizes things, but also change the initial position of them. For the circles to be distributed properly, I had to take into account the negative positions, since their origin was like being in the Center. With that, I could find the following code:

circle.setTranslateX( random.nextInt((int) cenario.getWidth()) - cenario.getWidth() / 2 );
circle.setTranslateY( random.nextInt((int) cenario.getHeight()) - cenario.getHeight() / 2 );

All this race about ended up giving me the tree of the following nodes:

The only little problem that 'left' now is when the user resizes the application. Once that circles are distributed whenever the application is resized they need be distributed again. My test application doesn't have with that in mind, but I think I can solve this problem easily using a layout that arranges the nodes by the edges of a panel using a proportional positioning. For example, should be a sign of provision for organizing nodes always a certain percentage of the edges. This can be done easily with a layout of the custom panel, because AnchorPane behaves in a different way.

I think that what I have to do now is go back and learn how to create a custom layout Panel. I want to thank all of you for your patience and your good intention to help. Thank you, really!

If anyone has anything to add, or corrections to what I said earlier, I would be very happy. The richest is this thread, best JavaFX is accepted for other users.

Can you post a NBS that illustrates the problem?

If you have a version of Java 8 corresponding to the current source code, it seems that the system attempts to select a node that is not attached to the graphic scene. This could happen in theory (I guess) If you change the chart of scene on the FX Application thread; but it's a blind guess.

There is no Node.LayoutZ? JDK 8.0, even when the API specifies its existing
OK so I might be confused, but it seems that the provision of a node defined there (X, Y) position as SetX and SetY would swing... However, there is no setLayoutZ... When I goto setTranslateZ it is said

'javafx.scene.Node '.
public final void setTranslateZ (double value)
Sets the value of the translateZ property.
Description of the property:
Defines the coordinate Z from the translation that is added to the transformed coordinates of this node. This value will be added to any translation defined by the transformations ObservableList and layoutZ. »

I guess I could put the Z translation, if necessary, but I'm confused what exactly the point of affecting the translation and layout if they do the same thing... IT seems as if the translation of setting is important for other things himself...

Remember PositionX, getScreenX, and getSceneX... >)
what I'm trying to do is set a box 3D x, y and z. Rectangle has x, y, but the box has nothing. Is it because it is too early in construction, or...? That's why I look at you I choose other methods. the only thing that makes sense is exactly the translation.

Simply use the properties translate for the positioning of objects in 3D at the moment (that's all that you have).

You may also cross this post to the discussion of possible changes to the api openjfx-dev list (such as adding a layoutZ property, a method to move some who takes z parameters for 3-d shape builders specify the initial values of page layout, etc., coordinates z, x, y, x).

I don't know if JavaFX will adopt eventually the concept of layout for use in a 3d scene graph, similar to how it works in a 2d scene graph - if it does then the above methods and properties would be desirable, otherwise they will be necessary (and everything should be done by using the coordinates translate only what you need to do today). My feeling is that finally the 3d scene graph will get 3d layout managers, but probably not in JavaFX 8 times (if you do not bring it upwards on openjfx-dev now or newspaper questions about jira, you can be assured that this facility is not available during the period of JavaFX 8).

Node.getSize ()?
Hi all

My Q is very simple...

How do I get the size (width / height) to a node?

I expect that there are: MyNode.getWidth () and MyNode.getHeight ()...
But they does NOT exist... or equivalent methods.

It's really ubnormal?

Thanks for any help...
The things that extend from region (for example, page layouts and controls) have width and height properties, so you can just do:
```
label.getWidth();
```
The nodes have different types of limits =>
http://docs.Oracle.com/JavaFX/2/API/JavaFX/scene/node.html#layoutBoundsProperty%28%29
http://docs.Oracle.com/JavaFX/2/API/JavaFX/scene/node.html#boundsInLocalProperty%28%29
http://docs.Oracle.com/JavaFX/2/API/JavaFX/scene/node.html#boundsInParentProperty%28%29

A simple program to illustrate that do this:
https://gist.github.com/1441960

In my words:
-Layout limits: the boundary of the shape.
-Delimits local: the boundary of the shape and the effect.
-Limits of Parent: the boundary of the shape, the effects and transformations.

Once you have the appropriate limits, you can query its width, height and depth.

For example:
```
node.getBoundsInParent().getWidth()
```
Note that if the node contains something resizable or css stylesheet, you really won't get a proper report to the limits until it was posted on a scene active and a pulse was performed on this subject. Thus, for example, the declared value for boundaries immediately after creating the node may differ from the value declared after that (scene) stage.show has been called. To always be informed of what is the height or width of a node, add a listener to the property of the appropriate limits, for example:
```
final DoubleProperty nodeWidth = new SimpleDoubleProperty(node.getWidth());
node.boundsInParentProperty().addListener(new ChangeListener() {
  @Override public void changed(ObservableValue ov, Bounds oldBounds, Bounds newBounds) {
    nodeWidth.set(newBounds.getWidth());
  }
});
```
Aspects of layout and controls have a property of convenience for this already, so you can do things like:
```
label.widthProperty().bind(scene.widthProperty());
```
Then there are things that calculates the preferred, minimum and maximum amounts for the nodes based on a given width or height. For nodes in constant sizes, these will always return the same value for resizable nodes, they can return different values. These should be used when in the subclassed layoutChildren call you create your own composite nodes (i.e. not so often and never if you are a beginner to write JavaFX programs).
```
node.minWidth(height)  // minimum width for a given height.
node.prefWidth(height)
node.maxWidth(height)
```
Finally resizable nodes that extend the region as part of layout and controls have the following properties, which you will likely finish by using a little:
```
region.minWidthProperty()
region.prefWidthProperty()
region.maxWidthProperty()  
```
For example region.getMaxWidth will return either
-Region.USE_PREF_SIZE-online maximum width will be the same as the default width.
-Region.USE_COMPUTED_SIZE-online maximum width will be of what is implemented in the default region.
-Some absolute value-online the maximum width will be all that a caller has chosen via region.setMaxWidth (value) call.
-Double.MAX_VALUE-online unlimited maximum width.

A good layout strategy is not to worry about sizes much at all, instead use resizable controls inside layout managers and set a default size of resizable controls only when you need to.

Help understand Node.boundsInLocal, Node.boundsInParent?

Hi all

I read the API JavaFX2 to understand the methods getBoundsInLocal() and getBoundsInParent() for a node. I understand the limits object that is returned. I want to better understand the difference between the two methods.

I read in the API that the getBoundsInLocal() method returns "the rectangular boundaries of this node in the coordinate space local transformed node." Am I correct in thinking that it is primarily the transformations? It would be the height, width, x and are coordinated during initialization?

The getBoundsInParent() method says "rectangular limits of this node include its transformations.» This includes transformations?

---

My next question is to understand the method of getBoundsInLocal() as it is used in this demonstration. Here is an example of creating custom button written by Eric Bruno (http://www.drdobbs.com/blogs/jvm/229400781).

In the class ArrowButtonSkin.java, Eric sets height and width of the label. When I run the program I see the value of width is - 1.0 and the height is 0.0. If the control is displayed as a dot on the screen. Is there a reason that the methods below are back-1 and 0? I don't know where I was wrong. It works if I put the values explicitly.

Double labelWidth = label.getBoundsInLocal () .getWidth ();
Double labelHeight = label.getHeight ();

Thank you very much for the help.

Limits of animation Clip?

Anyone know if there is a way to tie a knot so that when it has a scale applied or translate it does not extend beyond the boundaries of its container parent?

In the following code, the label fly all around the place, which is pretty cool. But I want that he be cut on the container that it is in (i.e. "animationArea") and does not pull on the top of all the other components of my scene. When the node is outside the animationArea would ideally be cut so that half the node is not established, etc. I want to make a sliding effect.

Amy work to make your life easier zonski-online http://javafx-jira.kenai.com/browse/RT-17441

Meanwhile, for your example of borderpane, add the animation of the center pane to your border before add you the outside and you will get a clip of pseudo-device because outside the borders have solid knowledge and will paint on top, see here for a longer explanation on why (I think) it works, and a sample program => Re : How can I implement a status bar at the bottom of a resizable application?

Another trick is to turn the depth buffer by specifying true as the last parameter to create scene and together as the translateZ of your entertainment center to 5 strand, then the label will be also hidden by all opaque on top of it. Platform.isSupported (ConditionalFeature.SCENE3D) to return true.

You can also calculate a form of clip to the field of Animation and place it on the animation pane, see http://download.oracle.com/javafx/2.0/api/javafx/scene/Node.html#setClip (javafx.scene.Node). This is probably the most "correct" solution There are Platform.isSupported (ConditionalFeature.SHAPE_CLIP) return true.

How to translate a node into a 3d for an exploded view pdf document?

Hello
I'm doing an exploded view of parts in 3d inside a 3d pdf. Each button has an action that moves to a certain part. I am able to rotate the pieces, but do not translate. Why so much?
This is the Javascript code I use:

C = getAnnots3D (0) [0] .context3D;
Mesh = C.scene.meshes.getByName ("geometry: 1");
v1 = new Vector3 (5,0,0);
mesh.transform.translateInPlace (v1);

The debugger Javascript said Vector3 is not defined! If I scale or do rotate work, but with the translation and the vector3, it doesn't. Something seems wrong with my definition of the vector.
Any advice?

Thank you very much!

It is a problem of context

Try:

v1 = new C.Vector3 (5,0,0);

Notification on the visibility of node

Hello

I use the node group to create the composition of nodes. Is it possible to get a notification when the composition node is visible?
I want to start an animation when the node of the composition became visible.

I tried adding a listener to changes to the visibleProperty of the group node but he never calls.

Thanks for any idea.

Adding items to an array dynamically to the current scene

Hello

I created an array with n elements. After 5 seconds, I want to add an extra element in the table and display it on the screen. And that's my problem. The function is called and the element is added (as far as I can see in debug mode), but it is not displayed. I tried the playFromStart function, but it does not help (in fact, it freezes the entire application). Here is my code:

for (j in [0..1]) {
    for (i in [0..1]) {
        insert Element {
            x: 
        } into Elements;
    }
}

def t1 = Timeline {
            repeatCount: Timeline.INDEFINITE
            keyFrames: [
                KeyFrame {
                    time: 25ms
                    values: []
                    action: function() {
                        for (Element in Elements) {
                            //do some fancy stuff :P
                        }

                    }
                }
            ]
        };

def t2 = Timeline {
            repeatCount: Timeline.INDEFINITE
            keyFrames: [
                KeyFrame {
                    time: 5s
                    values: []
                    action: function() {
                        insert Element {
                            x: random.nextInt(500), y: random.nextInt(500)
                        } into Elements;

                        //insert Elements into stage.scene.content;
                        t1.playFromStart(); //doesn't work...


                    }
                }
            ]
        };
var stage : Stage = Stage {
    title: "Test App"
    width: 500
    height: 500
    scene: Scene {
        content: [
            background, Elements
        ]
    }
}

What am I wrong with my code? Tips/advice, how can I get I work?

Hello user,

Please use bind for the changes in real time on scene.content;
And are the timeline must always be under the nodes (code statement) whose animation you are in treatment.

Thank you.

scene.nodes.getByName("...").transform in animation U3D annotation
