Delete a dynamic property of a dynamic object

I use a simple normal Flash as a data container object, and I want to delete a particular property of this object. Then this object is passed to a for... in loop. But even after using delete to remove the property, the key appears always in the loop.

For example:

var obj:Object = {a: 'a', b 'b', c 'c'}

Delete obj ["b"];

for (var prop: String in obj) {}

trace (prop + ":"+ obj [prop] ");

}

a: one

// b:

c: c

So delete the property seems to be the same as assign its value to null.

Is it possible to remove immediately the property of quite the object while he plays in a loop is no longer on one for... in loop?

It is enough to check the property to a null value, because a property with a null value is not the same as the property having no not first place and represents a different State. I don't want to set the property to null, I want to delete the property.

Is this possible in AS3?

This isn't how your code works on my machine.

var obj:Object = {a: 'a', b 'b', c 'c'}

trace ('Before');

for (var prop: String in obj) {}

trace ("" + prop + ":" "" + obj [prop]);

}

trace ("\nAfter");

Delete obj ["b"];

for (prop in obj) {}

trace ("" + prop + ":" "" + obj [prop]);

}

On my machine, here's how it works:

Front

b: b

c: c

a: one

After

c: c

a: one

    dzedward is right on target here Moses - and in addition there are a few things you can do here that will make you more fluid system work. If you pass the object instead of a string, you can use this reference to cause the reaction you method without having to 'check' all instances (which I think is what you go here) so you can simplify all using something more like the following:

  • Flattening of the dynamic objects to the original document and keep their Hi-Rez detail detail

    Hello, I am under difficulties with ram collapse my Photoshop files, please let me know if this is how to use smart objects for their Hi-Rez details, change your object voluntarily collapse / compress in the original document while retaining all of your changes and detail Hi-Rez to save on ram? If If Yes, what is the procedure?  I searched everywhere on the net and have not found an answer to this question.  I'm under that Photoshop CS6 extended on OSX 10.9 Mavericks.

    Thank you, Warunicorn, I do understand that you lose the benefits of dynamic objects, I guess what I'm trying to ask is to make you lose the appearance that smart objects gave you when you group documents? For me if the image looks still even with objects with or without smart objects their pixelated it does not matter that smart objects or they aren't. I seek only the general appearance, is he always looks good as he has done with smart objects. ?

    Thank you for your help,

    When just flattening? Of course, they look alike. It's when you go to register in a particular format is where things start to get sticky. (As the backup format JPEG.)

  • Dynamic objects of poor quality in Photoshop

    My apologies if this has already been answered, but I was able to find a solution. I want to add vector items saved in a creative library of clouds in a photoshop document, but when I insert smart objects they all appeared really pixelated. I used to be able to copy and paste directly from indesign, Photoshop, but the same thing is happening now.

    Any help would be greatly appreciated.

    Thank you very much

    If you want to transform a smart object layer.  If the object is a vector file placed as an .ai or .svg file the object layer dynamic will be a vector smart object and turn via vector graphics that will turn all other objects using interpolation.  If the object has Photoshop vector graphic elements. You can double-click content layer icon in the layers palette. This will open a working document in Photoshop, you can resize in Photoshop using vector graphics. When you save the work file Photoshop updates the dynamic object with your object resized layer. I don't use other Adobe products you can save vector files from indesign as .svg files?  And put them in you library. So far, I have not use libraries for all I use in Photoshop in a team not environment.  I can find a use one day Adobe libraries.

    I think that if the assets in a library and .svg file it would be placed in Photoshop as a vector smart object layer.

  • Dynamic objects in the disconnected model?

    Hello! I have a problem with the connection between smart objects and hope that someone can help me!
    A book-mock up I bought, contains a group of "Items" - layer - base, containing several dynamic objects.

    Those who are then used in different preview-layergroups (eg; before you book, inside the book, etc.)

    In this way, I can import/pages cover rear cover of my book-drawings and models in dynamic objects in the items-layer group, and then they are automatically changed in various layergroups. Or that's what's supposed to happen.

    However, somehow, a couple of smart objects was disconnected of the Basic smart objects, so rather than change all layers at once, I still spend several layers, one by one.
    Check the picture below

    In this way the dynamic object has lost part of its use... How to fix / reconnect the smart object?

    I got appriciate the feedback! Thank you!

    Try this (on a working copy, so you don't break anything, as if this works also depends on how the rest of the document is built)

    Click the object FLY Original layer, that you marked as a basic form of object and drag it to the new layer at the bottom of the palette icon.

    This will create a copy of the child of the dynamic object on a new layer

    Move this new layer of child in the same position that the layer with the broken link. Make this new layer visible and her broke the previous layer invisible by clicking on the symbols of 'the eye '.

  • PS CS6 video editing, change in position of the dynamic object

    Hello

    Correct me if I am mistaken in my project, I want to make a couple of small clips to appear on the screen and the change of position. I so in order for me resize a clip to convert object dynamic, right? But it seems that I can't use a 'position' function more on dynamic objects, (it disappeared). So, how can I transform an object while being able to use the tool "position? Is it work around?

    Kind regards

    Bart

    Instead of position, you will see " transformed" in the timeline that contains the positions and all other transformations.

  • Resize an exponential dynamic object

    I use script with dynamic objects animation to create the illusion that an object is moving toward the screen. The problem is, resizing, and using images key leave small "jumps" in the query whenever a keyframe passes. Is there a good way to have an exponential growth of the smart object in Photoshop? Or should I just bite the bullet and do it manually?

    What you are looking for then is 'Easements' - acceleration / deceleration. Ease (more slow as it comes to a stop), in (more rapid deceleration when it stops). In my version of Photoshop, it is not available. You can do a number of things - use Flash, After Effects or Premier to use the ease in/out function or do it manually as you originally thought. One option is to convert your animation script to frame and then remove the frames nears you the end. keep 1 remove 1, keep 1, remove 2, etc.. Then it will give the illusion of gets bigger and faster but still have the fluidity of the animation time online. I hope that helps!

  • show transform controls does not not as expected with dynamic objects.

    When I selected the move tool, I click the box see the transformation of the controls and it adds the controls as expected, but I can rarely actually use them.

    whenever you go to turn something, she sort of "resize" the bounding box and then allows you to use the controls. its really annoying, is there something else to check that it can fix? is it me? its been like it for too many versions specific version. -is a 'feature '?

    It seems to be a problem with the layers that are a dynamic object, works well with layer pixelated, but then you never want to intensify even when a layer of rasterised.

    "is there a way to force the controls' see the transform ' to use the actual limit box rather than the visible pixels, or that it works as expected and just let me transform with the original handles?

    Basic Page >

    001-item.jpg

    Select the item (automatic selection of layer on)

    002-item-select.jpg

    view transform controls

    003-item-slect-with-t-controls-on.jpg

    "hover" over the corner and get the icon of the transformation on the scale

    004-transform-controls-showing.jpg

    'Click' to try to get the corner...

    005-click-drag-to-scale.jpg

    and all of a sudden it changes layers limit real dimensions, (the size of maximum image to image dynamic objects) of the box and start to 'move' the layer,

    as you clicked actually within the area enclosing, not the corner as expected.

    006-bounding-box-changes-size.jpg

    Then, you have to cancel or move again, THEN use the transformation real corner as nationally.

    007-i-have-to-move-to-the-new-boundary-edge-to-transform.jpg

    OK, I think I "solved this myself" only took me 2 years to stop for two minutes to try to resolve the annoying behavior! Oops...

    Basically it happens when you're dealing with a layer that is a "placed picture" - another file that you drag onto your document.

    I thought wrongly it was layers of dynamic object, but its elements placed, the layer icon looks the same, so I didn't notice the difference in behavior.

    so the fix is

    Right-click on the layer and convert to smart object. It then behaves correctly!

  • Don't want to not automatically added to the library of dynamic objects

    With the update of 2015.1, using all existing documents when a dynamic object is created, or pasted from Illustrator etc it is automatically it adding to a library and sync to the cloud. I don't want this behavior, I want only the libraries contain objects that I purposely put there.  Is there a switch?

    Hi MicahBurke,

    When you display dialog box paste, there is a new option that is checked, the 'add to my current library' downstairs.

    Could you please uncheck the box.

  • I'm updating photoshop today and when I drag an object from illustrator to photoshop, the object doesn't turn into a dynamic object why?

    Update photoshop today and when I drag an object from illustrator to photoshop object market not turning into a smart object why?

    OK - think I have this sorted out now.

    When you copy and paste an Illustrator file in Photoshop, you get the dialog box PASTE.

    You can paste as smart object, Pixels, path and shape layer. In the past, you would select depending on what you want (in my case for most Smart Object) and viola - you have your dynamic object. However, in the newly revised version, there is a checkbox in low called "Add to my current library" If this box is checked, it becomes a library file that displays with a 'cloud' icon in the layer. If you uncheck the 'Add to my current library' it won't matter as a regular smart object.

  • Dynamic filters deactivation on dynamic objects while making connections in CC

    This just started today, but in trying to apply a filter of "Sharpness" to a .gif (video file) Smart Object, visibility of the filter turns off as soon as I click on the play button in the timeline panel.

    My approach is this:

    > Save the .gif on computer

    > Leader open .gif in PS CC

    > Convert all layers of dynamic object

    > Apply the sharpness filter to the smart object to create the smart filter

    > Click on 'Play' on the Timeline

    > * ISSUE: the smart filter becomes invalid. It won't save even when you export for the Web.

    I made connections for years using this process and it never became a problem until today. I wonder if it's just a bug in this version of PS CC? It's super annoying! Any help I could get would be fantastic. Thank you!

    To keep track, I'm not sure your workflow, but I'm guessing that at a given time convert you a chronology of "animation image" GIF to a collage "video". We are trying to fix a bug for the dynamic filters on video editing. The bug involved filters that do not have a dialogue window, sharpen, sharpen more, etc. These filters would be disabled to play or export. This could be the problem you see now. This problem appeared in Photoshop CC 2015. It will be fixed in the next update of Photoshop.

  • A problem when using dynamic objects related

    1. open an image in Lr using the command "open as smart object in Photoshop.

    2 convert the dynamic object opened in dynamic object associated with the Ps (save it in the same place where the original DNG file is by agreeing to replace)

    3. Save and close the TIFF file created in PS.

    4 make a few adjustments to the original DNG and save them in Lr in the DNG file.

    5. open the TIFF file and double-click the icon of yellow warning on the dynamic object bound to this day in the TIFF file.

    6. in ACR, simply click ok to update my linked smart object.

    7 and now without no cropping applied, my smart object related to the Ps is cropped automatically.

    How can I stop this automatic cropping?

    I solved my problem... Thank you.
