ActionScript 3.0 :: Change Transparency Of Background Dynamically Within An Area?
Dec 13, 2011
I have two backgrounds on different layers, and an object that can be dragged around. What I want to happen is that an area around the object should be transparent so you can see the background behind the first background, and when the object is moved, the transparent area should also move. Kind of like a "see-through" effect.
can i dynamically load a movie with transparency background? and one more thing i load a jpg with loadmovie command but the size of the jpg in pixel is not the same with the output of the fla..
Is it possible to add dynamically an button or graphic symbol into some area ?Let's say i have two buttons, and in particular case i would like to display first button in that area and another time i would like to replace that button with second or another graphic.
Here's the deal: I am working on a site that provides information for art buyers. Pricing, where to buy and things like that. The page is done in php, mysql, and some jQuery here and there.One of the things they want to implement is a live stream of auctions. What they want is something like this:Where on the left you'd see the stream -instead of the black block- and on the right, the image of the work that is currently being sold, with the artist name, title and price. That's what The image on the left should change as the auction progresses.What I need is to have and option in the admin area on the page, where the administrator can select the image to display. So, to implement this, I would need to:Connect to the database to get the information: pictures, data, etc.
Loop trough the record to get a list. From that list, the user will select the image he wants shown on the webpage.Have the admin area send the image to be displayed to the page, and have the page change it dynamically, without the user having to refresh the page.The first two points are no problem, what I'm not quite sure how to do is the third one. Flash? Some from of Javascript? I leaning towards flash, but anything will do. I'm sure what I'm asking for is nothing that hasn't been done before, but my google-fu has failed me on this one. I don't need copy and paste code, if you could point me to a tutorial on this, or the basics tools I'd need, that's great.
I'm having issues changing a TextInput background color after the initial onLoad using AS2. On load, I have no issues setting the background color with this code:
However, I have a form validator run when focus is lost but yet I cannot set the background color at that point. For example, I'm trying to set the background color to orange and text to white if the field's contents are invalid. Even something simple like this doesn't affect the colors.
It seems like there are various hacks out there to change the background colour of the row of a datagrid but all of them seem to happen at render time.See: http:[url]....I have a datagrid where I need to change row colours to red then back to normal frequently based on changes to the bound ArrayCollection. So I'm looking for a way to change the row colours dynamically.Obviously as the changes are happening frequently it would be nice if changing the background colour of the row wasn't an expensive process.
I have a collection of animated sprites with a brown background and I want to know how to make the brown transparent. Is there some kind of color keying in flash? The brown is #5E4229 by the way.
This has been bugging me for a little, and some of the examples I have tried to find throw me in loops and they have been wrong. [url]...
Or if you have ever played "Scorched Earth" you will see that when some part of the terrain is destroyed, it punches out the pixels perfectly when a shot is fired into the ground, to reveal the picture behind the main picture with the terrain.
I ran into an odd problem a week ago that I haven't been able to fix. I'm new to Flash so sorry if this has been discussed but my research has turned up nothing. I'm using Flash Develop. I managed to duplicate the problem in a simple program: I set up one large bitmap for the background, not transparent. I then add another large bitmap on top of that, the second layer background, as a child of the main bg. This layer has transparency so you can see the bg through the trees and such. Then I stack a lot of sprites on top of each other, all with transparency. They can be children of the main bg or the second layer bg, doesn't matter. Where the transparency of the sprites overlap the second layer background disappears completely to reveal the main background (like a window around the sprite stack.) The bitmaps I'm using are from embedded png files.
I found that 23 transparent objects causes the 24th object and beyond to disappear. And it only happens when I have a mask set to the main background (a simple filled square for clipping the child sprites that move off-screen.) Also the problem goes away while the background is moving. My project features many objects near each other so the chance of this problem occurring is pretty high. Its not game-breaking but I'm new to flash and my project is nearly complete (and large) so I'm hoping there is something simple I can do to fix this.
var menu = new Menu (); menu.x = 0; menu.y = 0;[code]...........
This works, but transparency varies for each element MovieClip separately, but I would like that would have changed the whole MovieClip transparency as a single image.
I want to create a website in flash for which i want to use the bg in flash to fit on 100% of width and height of browser in which it is opened (according to screen resolution) but want the content and other things used remain in same layout (they should not stretch) and remain in the middle area of the browser, like you see mostly a html page have a bg image which is set to fill 100% of width and height of the page.
is it possible with flash, i dont want to use bg image of html page (body tag background image)
I have a random motion script that I need to remove when the object in random motion hovers over a specific area in the background. I need the object to just keep moving in the direction it was going in and not randomly switch directions or bounce.This is my script for the random motion which is on the object:[code]
I want to add a text area on the click or a button, for example lets say if a person has multiple addresses and they want to add more address. When the user clicks 'add address' a new text area should appear.I have looked everywhere for the solution but no luck
Hear is the code that I have tried (and this could be very wrong):
import mx.controls.Alert; import mx.events.CloseEvent; private function createTextField(evt:Event):void{ var theTextField:TextField = new TextField();
I have a .jpg graphic in a movieclip on layer two (1024/768). This is used as a background.I have a .jpg scrolling movieclip on layer one. It is a very wide graphic used for displaying a panorama.I would like to be able to create, dynamically using actionscript, a transparent area on the layer two movieclip (create a window) to view the underlying movieclip.I believe this is possible using the Rectangle class in the flash.geom.rectangle but I can't figure out how to attach it to the layer two movieclip or how to make it transparent so shows the underlying scrolling graphic.
I have a Flash interaction where I exchange the cursor for a hand holding a flashlite mc. The entire stage is black. The cursor drags a mask around that illuminates a small image in another mc on the stage that the user has to find (illuminate).2 problems
1. When the mouse is rolled outside the stage, the custom cursor is still visible.
2. When imported into Captivate 3, and I move outside the stage and over buttons for navigation, the cursor is no longer visible, for the rest of the Captivate movie.
Desired functionality:Custom cursor to be visible only when on the stage area and the normal cursor to be visible outside the stage area. The stage area is 400x330.[code]
But when I go to click on something it uses the mouse's pointer still. I'd like to be able to drag with any part of my custom cursor(which is larger than a mouse).I've tried making a hit box that detects when the mouse is near the clip but it doesn't work onsistently(sometimes it just clicks like normal).Is there to make the clicking area of the mouse change?
I have some lines that I am assigning actions to upon MOUSE_OVER
The problem is that they are relatively small and kind of finicky to get the mouse directly over. When the mouse_over event occurs, I am changing their color to indicate they've been selected.
Is there a way I can change how sensitive they are to the mouse over event (i.e. detect MOUSE_OVER within 10 pixels of each MC or something)?
Here's the code I am using to asign the listeners and then to create a MOUSE_OVER event.
I'm having a slight problem with loading backgrounds dynamically. When the index page loads i need one bg.swf to load dynamically, but when the user clicks another background button, a new background will replace the default bg.swf that loaded automatically when the page opened. I understand to load the new bg's into an empty clip. I just need to know how to automatically load a .swf once the page opens. Pretty basic,
I recently learned about scrollRect. Can anyone tell me how efficient it is? by this i mean i have a huge background_mc and use a stage sized rectangle as the scrollRect to scan the insides of that movie Clip. (like a vcam i guess). Since it only renders the rectangle area , is it safe to say it doesn't matter how large "background_mc" is ? or is it better to dynamically add portions to the background when its just outside the stage.
