IDE :: Drag-and-drop Recognize Transparent Areas Of External PNGs?
Jan 21, 2009
I have a simple Flash movie which loads several external PNG-24 images into movie clipsEach movie clip is partially transparent (using alpha transparency), and made drag-and-droppable. Everything works properly except that for each movie clip, I am able to drag and drop the clip using the transparent space around the image. I want the "grab-able" area of each clip to correpond to only the non-transparent areas of the PNG, not a rectangular box around each movie clip.

Okay, this drag and drop thing seems fairly doable, but I've never tackled it before..I have about six items that I want to be able to drag and drop into their designated areas.I would like whatever mc that is being dragged to be put on the highest level, so I will need the set depths thing to work out.Also, if you drag an MC and release it but it's not on the correct target, I would like it to animate back to it's original position. Could you point me in the right direction as to how to do this? Or help me out with any code or source files you might have?

I am trying to make a quiz on metals. I have several elements which i want to fall into multiple target areas (e.g. the target areas are shaded grey in the following swf; metal_mc, nonmetal_mc, metalloid_mc). I can make individuals match to target areas (as there are tutorials for that) but i want each one to be able to slide in to any target area (and someday i want to create a solve button which will then place each element in the correct place). have started all over and have designated only chlorine to move (for the moment) but how do i code it to allow it to fall into any of the grey areas?
var objectoriginalX:Number;var objectoriginalY:Number;chlorine_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);chlorine_mc.addEventListener(MouseEvent.MOUSE_UP, dropIt);function

Has anyone ever encountered this weird, unique error I am gettingWhen I export my program to a SWF all the imported PNGs with alpha transparency (ie; soft edges) render totally wrong - no transparency, very blocky and pixelated. See the attached image for an example;this is out of the blue. Has exported fine recently.

I need to important transparent pngs into my SWF, and have them clickable as buttons. Right now, I'm using JPGs with the loader component, but I'm aware this method does not work with PNGs.

I have an artist I'm paying to do animation art for me. I need PNGs for each frame in the animation but she is most comfortable doing her animations in Flash. It sounds like getting the frames for me will be difficult for her. She was able to do the still art we needed and give us that as a frame, but for some reason the animation is different? Keep in mind we need PNGs with full transparency support in the background. We can't be clipping these frames out by hand.

i have a transparent (in places) png in a movieclip, can i use that png in the movie clip as a mask? i have seen lots of ways of creating compositions but i need the mask movieclip on the top to be able to mask a movieclip underneath that has lots going on animation wise? is this possible. i dont need answers i just need the right direction or a yes or no, i fail to believe i cant copy the bitmap data of a movieclip (and the transparent png images in it) and then use that as a mask

I'm having an issue with solid backgrounds showing up behing transparent PNGs in Flash. I know this isn't a lot to go on, but I have no idea what is going on here, My client sent me the attached image.. This is what they are seeing (the green box behind the top of the vehicle). I am not seeing this. Apparently this box, and other similar boxes show up during image transitions.
I am using Tweens to fade between different models and colors of the vehicle. I was originally using Caurina/Tweener, and experienced similar issues myself, but since switched to using the built in tween class, and am not seeing any problems anymore, but apparently my client is.You should be able to see the attached image. You can also view the demo link, to see if you see any issues yourself with the PNGs fading in and out....(you'll have to sit through the intro, then click EXPAND on the final frame)

I wanted to put on the stage a png file with some transparent areas, unfortunately it weight too much.So instead I thought I'll create a shape object and use jpeg image as it's mask...
This is my code:
Code:
package {
import flash.display.Bitmap;
import flash.display.Shape;
[code]....
And it doesn't work, can I use jpeg images to mask the shape at all?

I made a simple test Air application to try different approaches to masking or using hitArea to ignore mouse events over transparent areas of a PNG. Can't seem to find the right mix of things to make it work, nor could I find a succinct example on the web.Clicking on the transparent areas of any of these methods don't result in the click getting handled by the background.Here's the code I have:

I'm having troubles getting the dimensions I'm looking for for a given display object. This display object has some transparent area to the top-left of the opaque content but to the bottom-right of 0,0. As such, the display object's reported width ONLY includes the opaque area, not the transparent area. For example:
Code:
var myChild:Sprite = new Sprite();
myChild.graphics.beginFill(0xff0000);
myChild.graphics.drawRect(100, 100, 100, 100);
myChild.graphics.endFill();
trace(myChild.width);
This reports 100 as the width and height. I need to somehow retrieve 200 as the width and height.
I'm trying to take a bitmapdata snapshot of the display object, but when I do new BitmapData(myChild.width, myChild.height) and then draw into it I don't get the full opaque content of myChild drawn because the dimensions are too small.

I've got a movie clip with masked-out areas. It's placed on top of various buttons.The idea is, the user rotates the top movie clip to reveal stationary buttons beneath it. Where there's a hole in the top movie clip, i'd like the user to be able to click the button revealed below.
It's looking like that's not possible. The buttons underneath cannot be activated, because the top movie clip is in the way, despite the transparency from the mask.
I'll begin thinking of a Plan B workaround, but first I wanted to ask if there's a way I'm not thinking of to do my Plan A.

I am having problems with optimizing a code. I am not new to Flash (not an expert though) but as much as I work and read it seems that there are lots of things I don't know. I hope you could help me with this.
So..I have 192 buttons (each in different colors) and 192 arrows. The arrows are invisible in the first place. When I press one of the buttons I want the coresponding arrow to appear, hide the mouse and make it act like a mouse. I also want to be able to drop the color of the button on an external movieclip.

I loaded some images from an external XML file, and tried to add a startDrag() & stopDrag() on my actionscript, but it got an error. "ReferenceError: Error #1069: Property startDrag not found on flash.display.Loader and there is no default value."
this is the data in my XML File
Code:

I think my "MouseEvent.CLICK" is conflict with "MouseEvent.MOUSE_DOWN or MOUSE_UP"
How can I drag up & down an IMAGE from an ARRAY or XML LIST since it will just LOAD a one variable array?

I would like to know how to set up the URLRequest to load an external image to a movie clip that is being used in a Drag and Drop event.I have successfully implemented the drag & drop code to my design but I would like to improve it by successfully loading external images to those objects that are being dragged around.I have both Var Load and starDrag codes. I am trying to figure out how to combine them.

Flash can compress .png files like Photoshop can compress .jpg files better than any other tool hands down. I have 77 .png files that are 1.8 .megs on my c: drive after I imported them and setting the file compression under the "File > Publish Settings" to 75% for jpg and published the .swf with all the .png on the stage the file size is 350K that's about 20% of the original file size of the .pngs downloaded file by file with 77 separate request.
I can create linkage in the shared .swf and test the movie with code in the shared .swf to add the movieclip holders for each:
.png to the stage but when I load the shared .swf into the main
.swf Flash acts like it can't create the classes based on the
Linkage I setup or that the MovieClip linkage doesn't exist.
I tried a test to have the shared .swf with all the .pngs and linked movieclips to add the assets to it's own stage and it works fine but that means a lot of my code and logic is included in the shared .swf that the designers need to add .pngs to. We need to have the main .swf get a handle of the linked .png assets and place them in the main .swf to load the assets to different parts of the main .swf. It's cute that the shared .swf can add the linked assets to it's own stage but not too useful.
Also the way we deploy we cannot roll out a new release/build to update the .pngs but we can upload a new .swf to the asset server so the .pngs need to be in a separate .swf. I can get the shared MovieClip to add the linked assets to it's own stage when testing and when loading my problem is the main .swf that loads the shared .swf cannot create instances of the classes that are exported for runtime sharing using linkage.

I'm trying to make a simulation where a person can drag 2 different objects to any 4 predefined targets on the stage. Based on the position of the 2 objects there will be a different output text. I hope I described that clearly. I would also like the 2 objects to snap to the 4 targets. Im very new to AS. Im starting to be able to read it a bit but still can not wright it.

Im trying to do a drag and drop system where the user can drag a movie clip into an area. Although i would like to make it snap to a target instead of just sitting wherever it lands in the area. Problem Two:
The next thing i am trying to do is when the user has a movie clip on a target already, and trys to put another movie clip in that target area, it will replace the one thats in there and go back to its current position. Here is the script of what i have done so far:

I have added drag and drop to some of my custom components.The drag event is fired on mouse down.If you mouse down and move the component around then drop it repeatedly its fine.But if you mousedown and drag the component around drop it and THEN just click on the component it inits the drag but doesn't fire the drop event.Its almost like you have to move the component for it to fire the drag drop event.This is very annoying as i'm removing the component on drag init and adding it again on drop, so just clicking on it makes it disappear.
