ActionScript 3.0 :: Transparency And Mouse Handling?
Jan 5, 2010
If I have a graphic that is fully transparent in places, can I make only the non-transparent portions of the graphic respond to mouse clicks? I realize I can probably do this with a few lines of code, e.g. detect the click and then check the alpha value under the mouse. But I was looking for something simple. For example, in Director there is an "alphaThreshold" in a graphic that determines at what alpha value a bitmap will respond to mouse clicks. Does Flash / AS3 have a similar capability?
I have a flash that has a background symbol that responds to CLICK event. On top of that symbol I have a sprite that contains a Bitmap with transparent pixels. Both of them are added to the stage, so they are not related directly.
I want clicks on the transparent pixels on the sprite to go straight through to the background. I have read about mouseEnabled / mouseChildren but have not been able to make these work. The symbol ignores the mouse events when I use them, but does not pass it along as if its transparent.
Is this possible to do with flash? Or will I have to re-route mouse events?
I have prepared a simplified test case for my question. It will run instantly in your Flash Builder if you put the 2 files below into a project.I'm trying to display a List of strings and a confirmation checkbox in a popup:In the real application I dispatch a custom event with the string selected in the list, but in the test code below I just call trace(str);My problem: if I use click event, then the window closes, even if I click at a scrollbar (the !str check below doesn'twhen an item had been selected in previous use). And if I use change event, then the window doesn't close, when I click on the same item as the last time.riting a custom item renderer and having a click event handler for each item seems to be overkill for this case, because I have strings in the list.Test.mxml: (please click myBtn few times - to see my problems with click and change)
I'm creating a DressUp kind of game using only external .png files for items (such as dresses, hair styles, bags etc).Some of my image files have transparent space left/right of the drawing itself. What I want to do, is set the hitArea of that certain movieclip (which contains the .png file) only to the visible area (to the actual drawing). This would be a fairly easy job if all the items had have the same size, but sizes are different from item to another.Taking the attached image, the grey area should not respond to mouse events.
I created an image in Photoshop that included a gradient layer fading from transparency to a foreground color (in this case, black). I saved this image as a PNG file and imported the file onto my Flash stage. The gradient appears on the image as expected when viewing the stage in the Flash editor, however, when I test the movie, the gradient no longer appears.
I have created a swf for the header of my website. On the top layer I have an image that stays static while the rest of the header changes images. I am trying to get the static image to be fairly transparent but am not having much luck. I created the image in PS I saved it with transparency but it doesn't look right in the swf.
URL..they rocky frame you see is a PNG and it's converted in MovieClip to be able to change it's index so it's always in front of the other objects.Problem: once I get what I want (MC+png is in front of everything) I'm not able to interact with anything under the MC anymore.I know the problem it's that the png extends for all the MC space but I really need to make those object under the frame interactable.
I have a PSD with about 30 layered transparencies. I exported each individual layer as a PNG 24 with the transparent background in tact. I then made identical layers in Flash just like I had in Photoshop, and imported each PNG to it's corresponding layer at which point I converted the graphic to a movie clip for future scripting animations. Once I got to the 24th layer Flash quit recognizing my transparencies and my first Flash layer masked anything else I brought in from layer 24 on....but the layers above remained OK!! I checked and double checked my Photoshop exports and had several Flash "gurus" check my work. Nobody can figure out what is wrong! Is there a limit to the number of PNG tranparencies allowed on seperate layers in a Flash document?
I'm working on a project where I want to use a transparent png, and when authoring in Flash CS3 (using actionscript 2.0) the png image appears transparent just as it should. However when I test it the .swf file loses the transparency entirely. The png image was saved for web from photoshop as png-24.
With CS3, when I entered a movieclip, I could see the other movieclips/stage in the background. But now when I enter a movieclip with CS4, I get the stage color as the background. If I try to test that "scene", the objects are in the top left corner.
It makes positioning from within a movieclip very very difficult.
I have a flash SWFObject on a pafge and i want to make the background transparent so that the base HTML background shows through. This is my code:
var so = new SWFObject("images/topnav.swf", "flash", "100%", "100%", "6","#000000"); so.addVariable("xml", "data.xml?time="+new Date().getTime()) so.write("flashcontent");
Is there a way to turn off the transparent appearance of the toolbars when you drag them in Flash CS3. For example, when I drag the actionscript toolbar, it turns transparent and it's really lagging on my system
I have a problem I can't seem to fix - why wont the transparent attributes of the PNG files I have substituted into the XML gallery wont show? instead there is a heavy white border that overlaps other images in when the flash is rendered
var tn:Number = 0; var current_tn_x:Number; var current_tn_y:Number;
I'm an art student and have produced some pieces in Flash 8. Now I've been asked for a high-quality (i.e. a letter-sized print at 600dpi) image, but the animation uses transparency.
I've been able to generate vector-based PDFs that I can blow up to as big as I want with no quality loss, but the transparency dissappears.
When I conserve the transparency, I get something that'll print at about 1/10 the size I need at 600dpi.
If it's not possible from the Flash Player (or from Flash 8), then does anyone know of an alternate program that'll do this for me (preferably free or cheap)?
I am trying to get the alpha values in the rect of one (playball_mc) clip inside another bigger clip (dst_mc). The clip dst_mc has a bitmap attatched and also has a shaderFilter that calculates the alpha values.ut I only get alpha values of 0xFF.Does anyone know what I am doing wrong or where the alpha value gets lost?
CODE:var rSource:Rectangle=new Rectangle(playball_mc.x,playball_mc.y,80,80) dst_bmp.draw(dst_mc);bmd1.copyPixels( dst_bmp , rSource, new Point(0,0) ); for
I'm using AS2 with Flash CS4. How can I change the alpha of a ComboBox? I tried: MyCombo._alpha = 25; // and MyCombo.alpha = 25; But both have no effect on my ComboBox, it just appears to have the alpha set to 100.
What's the best way to bring in an image with transparency in Flash CS4?I have a logo in Photoshop that looks great on a black background. But when I bring it in as a GIF or PNG in Flash, the edges get really jagged.Is there a preferred way to import this so the edges are smooth?
I need to use te colorTransform to change the color of one movieclip in stage. I can do it, but I loose the original degrades illustration has. How to apply the color transform but defining one alpha to the new color, so what is being fill doesn't looses its appearance?
I've made a flash image with the gif extention with Adobe Flash CS4 Pro. I have set the WMODE to tranparent and i've set the Transparency at the giv tab to transparent to. But now comes the difficult part. Each time when I export the image the background is still white.
Im trying to create an as3.0 navigation with a few buttons.Each button is a png image.When im importing images to the stage i dont have any transperancy issues but the problem is that they are not smooth enough, especially because im animating them using TweenLite.I thought that the only way to do it properly is to load all the images using as3 into bitmap objects and then use the smoothing property.The problem is that everytime that i assign the png to a bitmap object i lose the transperancy information and i get a white background...Anyone knows how can i keep the transperancy information from the png onto the bitmap object ?
I have created a peelback advert that peels down from the top right. All is well apart from it it obstructs the user ability of the site underneath as the peelback advert is effectively over the top. I have been giving some guidlines to stop this but i am struggling to understand them. The instructions specificall say that the file must be set with the transparent parameter.
Here are the options that i have:
OPTION 1: import flash.external.ExternalInterface; // Function executed in answer to the event function onClic(pEvt:Event):void {
[code]...
I think it could be the latter two that i need but am not entirely sure, i have tried them but have failed in my attempts?!If this is definetly the way to do it i will persevere! If these are not the way, what does the corner_show/hide method method do?
I want to apply transparency to a non-transparent logo then add it to an image. So I change the alpha of the logo, then I draw() the logo on the image. But it doesn't work, the transparency isn't applied as expected.
Note: I will later save the resulting bitmapData to a file, so an addChild() won't be enough to solve this.
var image:Bitmap; var logo:Bitmap; //... logo.alpha = 0.3; image.bitmapData.draw(logo);
i placed png file inside movie clip... when a event trigger the image there should pop up appear.. main thing is the event should not trigger in the transparent image area.. using as3..
